Purpose:
Publicly available health information is increasingly important for patients and their families. While the average US citizen reads at an 8th-grade level, electronic educational materials for patients and families are often advanced. We assessed the quality and readability of publicly available resources regarding hypoplastic left heart syndrome (HLHS).
Methods:We queried four search engines for “hypoplastic left heart syndrome”, “HLHS”, and “hypoplastic left ventricle”. The top 30 websites from searches on Google, Yahoo!, Bing, and Dogpile were combined into a single list. Duplicates, commercial websites, physician-oriented resources, disability websites, and broken links were removed. Websites were graded for accountability, content, interactivity, and structure using a two-reviewer system. Nonparametric analysis of variance was performed.
Results:Fifty-two websites were analysed. Inter-rater agreement was high (Kappa = 0.874). Website types included 35 hospital/healthcare organisation (67.3%), 12 open access (23.1%), 4 governmental agency (7.7%), and 1 professional medical society (1.9%). Median total score was 19 of 39 (interquartile range = 15.8–25.3): accountability 5.5 of 17 (interquartile range = 2.0–9.3), content 8 of 12 (interquartile range = 6.4–10.0), interactivity 2 of 6 (interquartile range = 2.0–3.0), and structure 3 of 4 (interquartile range = 2.8–4.0). Accountability was low with 32.7% (n = 17) of sites disclosing authorship and 26.9% (n = 14) citing sources. Forty-two percent (n = 22) of websites were available in Spanish. Total score varied by website type (p = 0.03), with open access sites scoring highest (median = 26.5; interquartile range = 20.5–28.6) and hospital/healthcare organisation websites scoring lowest (median = 17.5; interquartile range = 13.5–21.5). Score differences were driven by differences in accountability (p = 0.001) – content scores were similar between groups (p = 0.25). Overall readability was low, with median Flesch–Kincaid Grade Level of 11th grade (interquartile range = 10th–12th grade).
Conclusions:Our evaluation of popular websites about HLHS identifies multiple opportunities for improvement, including increasing accountability by disclosing authorship and citing sources, enhancing readability by providing material that is understandable to readers with the full spectrum of educational background, and providing information in languages besides English, all of which would enhance health equity.

Background:
Intraoperative imaging determines the integrity of surgical repairs. Transoesophageal echocardiography represents standard care for intraoperative imaging in CHD. However, some conditions preclude its use, and epicardial echocardiography is used alternatively. Minimal literature exists on the impact of epicardial echocardiography versus transoesophageal echocardiography. We aimed to evaluate accuracy between the two modalities and hypothesised higher imaging error rates for epicardial echocardiography.
Methods:We retrospectively reviewed all epicardial echocardiograms performed over 16 years and compared them to an age- and procedure-matched, randomly selected transoesophageal echocardiography cohort. We detected un- or misidentified cardiac lesions during the intraoperative imaging and evaluated patient outcomes. Data are presented as a median with a range, or a number with percentages, with comparisons by Wilcoxon two-sample test and Fisher’s exact test.
Results:Totally, 413 patients comprised the epicardial echocardiography group with 295 transoesophageal echocardiography matches. Rates of imaging discrepancies, re-operation, and incision infection were similar. About 13% of epicardial echocardiography patients had imaging discrepancies versus 16% for transoesophageal (p = 0.2352), the former also had smaller body sizes (p < 0.0001) and more genetic abnormalities (33% versus 19%, p < 0.0001). Death/mechanical support occurred more frequently in epicardial echocardiography patients (16% versus 6%, p < 0.0001), while hospitalisations were longer (25 versus 19 days, p = 0.0003).
Conclusions:Diagnostic accuracy was similar between patients undergoing epicardial echocardiography and transoesophageal echocardiography, while rates of death and mechanical support were increased in this inherently higher risk patient population. Epicardial echocardiography provides a reasonable alternative when transoesophageal echocardiography is not feasible.

Background and hypotheses:
High venous pressures and associated hepatic congestion are important drivers for Fontan-associated liver disease. The prognostic significance of hepatomegaly as a marker of congestion however is not well defined and is further explored in this research study.
Methods:Fontan patients who have had liver ultrasound scans were identified from the Prince Sultan Cardiac Centre Fontan Database and had their anatomic, surgical, clinical histories abstracted from the electronic medical records following institutional ethics approval. Liver volumes were determined retrospectively from reviewing individual US images, and these, divided into tertiles, were analysed in the context of the predefined endpoints of (i) Primary – death or heart or liver transplantation, or (ii) Secondary – combined endpoint of death, transplantation, arrhythmia, or protein-losing enteropathy.
Results:Mean indexed liver volumes for the entire cohort (n = 199) were 1065.1 ± 312.1 ml/m2, range 387 to 2071 ml/m2. Patients with the largest liver volumes (highest tertile) were less likely to have a functioning fenestration compared to those in the lowest tertile 44% versus 56% p = 0.016 and experienced the highest burden of mortality and heart or heart–liver transplantation, p = 0.016, and were more likely to reach the composite endpoint of death, protein-losing enteropathy, arrhythmia, or transplantation, p = 0.010. Liver volumes had an overall predictive accuracy for the combined outcome of 61% (CI 53%, 67%, p = 0.009).
Conclusions:Liver volumetry may serve as a potentially important congestion biomarker for adverse outcomes after the Fontan operation.

Multiple studies have endeavoured to define the role of steroids in paediatric congenital heart surgery; however, steroid utilisation remains haphazard. In September, 2017, our institution implemented a protocol requiring that all neonates undergoing cardiac surgery with the use of cardiopulmonary bypass receive a five-day post-operative hydrocortisone taper. This single-centre retrospective study was designed to test the hypothesis that routine post-operative hydrocortisone administration reduces the incidence of capillary leak syndrome, leads to favourable postoperative fluid balance, and less inotropic support in the early post-operative period. Data were gathered on all term neonates who underwent cardiac surgery with the use of bypass between September, 2015 and 2019. Subjects who were unable to separate from bypass, required long-term dialysis, or long-term mechanical ventilation were excluded. Seventy-five patients met eligibility criteria (non-hydrocortisone group = 52; hydrocortisone group = 23). For post-operative days 0–4, we did not observe a significant difference in net fluid balance or vasoactive inotropic score between study groups. Similarly, we saw no major difference in secondary clinical outcomes (post-operative duration of mechanical ventilation, ICU/hospital length of stay, and time from surgery to initiation of enteral feeds). In contrast to prior analyses, our study was unable to demonstrate a significant difference in net fluid balance or vasoactive inotropic score with the administration of a tapered post-operative hydrocortisone regimen. Similarly, we saw no effect on secondary clinical outcomes. Further long-term randomised control studies are necessary to validate the potential clinical benefit of utilising steroids in paediatric cardiac surgery, especially in the more fragile neonatal population.

Introduction:
Ventricular septal defect is one of the commonest heart defect in children and closure of this defect with devices has seen a rapid progression over a period of time. The availability of new and safer devices has made the transcatheter closure of ventricular septal defect a suitable option even in young children.
Aim:The study was done to evaluate the feasibility and complications of device closure of ventricular septal defect in children weighing 10 kg or less with different types of devices.
Methods:The present study was undertaken in a newly established dedicated Paediatric Cardiac Unit at a Tertiary Care Hospital. Relevant data were obtained retrospectively from the case files and the catheterisation records and data were analysed for first 50 patients with ventricular septal defect weighing 10 kg or less between March 2018 and March 2021.
Results:Among these 50 patients selected, device closure was successfully done in 45 (90%) cases while 5 (10%) attempts were unsuccessful for various reasons. The mean weight in this study was 7.46 ± 1.89 kg (2.3–10 kg), 21 (42%) cases were females while 29 (58%) were males; mean age was 19.4 ± 11.88 months (4–48 months). Right heart catheterisation study showed 21 (42%) patients with normal pulmonary artery pressures (no pulmonary artery hypertension). Among 29 patients with pulmonary arterial hypertension, 13 patients (22%) were having mild pulmonary arterial hypertension, 4 (8%) were with moderate pulmonary arterial hypertension, and 12 (24%) were with severe pulmonary arterial hypertension. Mean Qp/Qs was 2.73 ± 0.72 (2.5–4.5) and mean pulmonary vascular resistance was 1.5 ± 1.04 (0.6–4.6 WU). Amplatzer Duct Occluder (ADOI) was used in 15 (30%) cases, 27 (52%) cases were closed with Amplatzer Duct Occluder (ADOII), and the 3 (6%) cases closure was done with Amplatzer muscular ventricular septal defect occluder.
Conclusions:Transcatheter closure of ventricular septal defect in children 10 kg or less is feasible and safe alternative to surgical ventricular septal defect closure. The immediate and short-term outcomes have proven this method to be safe and valid.

Background:
Following cardiac surgery, infants often remain endotracheally intubated upon arrival to the cardiac ICU. High-flow nasal cannula and non-invasive positive pressure ventilation are used to support patients following extubation. There are limited data on the superiority of either mode to prevent extubation failure.
Methods:We conducted a single-centre retrospective study for infants (<1 year) and/or <10 kg who underwent cardiac surgery between 3/2019–3/2020. Data included patient and clinical characteristics and operative variables. The study aimed to compare high-flow nasal cannula versus non-invasive positive pressure ventilation following extubation and their association with extubation failure. Secondarily, we examined risk factors associated with extubation failure.
Results:There were 424 patients who met inclusion criteria, 320 (75%) were extubated to high-flow nasal cannula, 104 (25%) to non-invasive positive pressure ventilation, and 64 patients (15%) failed extubation. The high-flow nasal cannula group had lower rates of extubation failure (11%, versus 29%, p = 0.001). Infants failing extubation were younger and had higher STAT score (p < 0.05). Compared to high-flow nasal cannula, non-invasive positive pressure ventilation patients were at 3.30 times higher odds of failing extubation after adjusting for patient factors (p < 0.0001).
Conclusions:Extubation failure after cardiac surgery occurs in smaller, younger infants, and those with higher risk surgical procedures. Patients extubated to non-invasive positive pressure ventilation had 3.30 higher odds to fail extubation than patients extubated to high-flow nasal cannula. The optimal mode of respiratory support in this patient population is unknown.

Objective:
Owing to its obvious cosmetic appeal, minimal invasive repair of congenital heart defects (CHDs) through the mini right axillary thoracotomy is becoming routine in many centres. Besides cosmesis, and before becoming a new norm, it is important to establish its outcomes as safe compared to repairs through traditional median sternotomy.
Methods:Between 2013 and 2021, 116 consecutive patients underwent defect repairs through mini right axillary thoracotomy. Patient, operative data, and hospital outcomes were compared to contemporary mini right axillary thoracotomy and sternotomy series.
Results:There was no mortality or need for approach conversion (mean age 4.3 years, range 0.17–17, mean weight 18.6 kg, range 4.8–74.4) in 118 repairs for atrial septal defect, ventricular septal defect, partial anomalous pulmonary venous return, partial atrioventricular canal with mitral cleft, scimitar syndrome, double-chambered right ventricle, cor triatriatum, and tricuspid valve repair. Protocol included on-table extubation, achieved in 97 children, with 23 outliers leading to 0.7 average hours of mechanical ventilation (range 0–66 hours), indwelling chest drain time of 2.6 days (range 1–9 days), intensive care stay of 1.8 days (range 1–10 days), and hospital stay of 3.9 days (range 2–18 days). Late revisions were required in one patient after scimitar repair for scimitar vein stenosis at 2 weeks, and in another for repair of superior caval vein stenosis after a Warden operation at 2 months; reoperations (5/116 = 4.3%) were successfully performed through the same mini right axillary incision.
Conclusions:While providing obvious cosmetic advantages, the minimally invasive right axillary thoracotomy approach for the surgical repair of common CHDs yields excellent results and is safe compared to the benchmark median sternotomy approach.

Background:
Paediatric cardiac critical care continues to become more sub-specialised, and many institutions have transitioned to dedicated cardiac ICUs. Literature regarding the effects of these changes on paediatric critical care medicine fellowship training is limited.
Objective:To describe the current landscape of cardiac critical care education during paediatric critical care medicine fellowship in the United States and demonstrate its variability.
Methods:A review of publicly available information in 2021 was completed. A supplemental REDCap survey focusing on cardiac ICU experiences during paediatric critical care medicine fellowships was e-mailed to all United States Accreditation Council of Graduate Medical Education-accredited paediatric critical care medicine fellowship programme coordinators/directors. Results are reported using inferential statistics.
Results:Data from 71 paediatric critical care medicine fellowship programme websites and 41 leadership responses were included. Median fellow complement was 8 (interquartile range: 6, 12). The majority (76%, 31/41) of programmes had a designated cardiac ICU. Median percentage of paediatric critical care medicine attending physicians with cardiac training was 25% (interquartile range: 0%, 69%). Mandatory cardiac ICU time was 16 weeks (interquartile range: 13, 20) with variability in night coverage and number of other learners present. A minority of programmes (29%, 12/41) mandated other cardiac experiences. Median CHD surgical cases per year were 215 (interquartile range: 132, 338). When considering the number of annual cases per fellow, programmes with higher case volume were not always associated with the highest case number per fellow.
Conclusions:There is a continued trend toward dedicated cardiac ICUs in the United States, with significant variability in cardiac training during paediatric critical care medicine fellowship. As the trend toward dedicated cardiac ICUs continues and practices become more standardised, so should the education.

Investigations are still ongoing about the pathophysiology of multi-system inflammatory syndrome in children, which can progress with serious morbidity and mortality after COVID-19 infection. In this study, we aimed to investigate whether fibroblast growth factor-2 and tumour necrosis factor alpha-stimulated gene-6 levels play a role in the diagnosis of the disease and on cardiac involvement. Twenty-three patients (11 girls, 12 boys) and 26 healthy controls (10 girls, 16 boys) were included in the study. The mean age of the patient and control group was 8.45 ± 2.43 and 10.73 ± 4.27 years, respectively. There was no difference between the fibroblast growth factor-2 and tumour necrosis factor alpha-stimulated gene-6 levels of the patient and control groups. When the patients with myocardial involvement in the patient group were compared with the patients without myocardial involvement in terms of fibroblast growth factor-2 and tumour necrosis factor alpha-stimulated gene-6 levels, no difference was found between these groups. The correlation of fibroblast growth factor-2 and tumour necrosis factor alpha-stimulated gene-6 levels with other laboratory parameters was investigated in the patient group. Fibroblast growth factor-2 was moderately inversely correlated with white blood cell count (r = -0.541, p = 0.008), absolute neutrophil count (r = −0.502, p = 0.015) and C-reactive protein (r = −0.528, p = 0.010). Fibroblast growth factor-2 was strongly inversely correlated with erythrocyte sedimentation rate (r = −0.694, p =<0.001). Our data show that fibroblast growth factor-2 and tumour necrosis factor alpha stimulated gene-6 do not provide sufficient information about diagnosis and cardiac involvement in multi-system inflammatory syndrome in children.

Objectives:
To determine potentially modifiable risk factors for a complicated Glenn procedure (cGP) and whether a cGP predicted adverse neurodevelopmental and functional outcomes. A cGP was defined as post-operative death, heart transplant, extracorporeal life support, Glenn takedown, or prolonged ventilation.
Methods:All 169 patients having a Glenn procedure from 2012 to 2017 were included. Neurodevelopmental assessments were performed at age 2 years in consenting survivors (n = 156/159 survivors). The Bayley Scales of Infant and Toddler Development-3rd Edition (Bayley-III) and the Adaptive Behavior Assessment System-2nd Edition (ABAS-II) were administered. Adaptive functional outcomes were determined by the General Adaptive Composite (GAC) score from the ABAS-II. Predictors of outcomes were determined using univariate and multiple variable linear or Cox regressions.
Results:Of patients who had a Glenn procedure, 10/169 (6%) died by 2 years of age and 27/169 (16%) had a cGP. Variables statistically significantly associated with a cGP were the inotrope score on post-operative day 1 (HR 1.04, 95%CI 1.01, 1.06; p = 0.010) and use of inhaled nitric oxide post-operatively (HR 7.31, 95%CI 3.19, 16.76; p < 0.001). A cGP was independently statistically significantly associated with adverse Bayley-III Cognitive (ES −10.60, 95%CI −17.09, −4.11; p = 0.002) and Language (ES −11.43, 95%CI −19.25, −3.60; p = 0.004) scores and adverse GAC score (ES −14.89, 95%CI −22.86, −6.92; p < 0.001).
Conclusions:Higher inotrope score and inhaled nitric oxide used post-operatively were associated with a cGP. A cGP was independently associated with adverse 2-year neurodevelopmental and functional outcomes. Whether early recognition and intervention for risk of a cGP can prevent adverse outcomes warrants study.

“Harlequin effect” may be observed in the watershed region of a patient with pulmonary dysfunction, receiving peripheral veno-arterial extracorporeal membrane oxygenation via the femoral vessels. In such cases, retrograde oxygenated blood from the peripheral inflow cannula converges with the antegrade deoxygenated blood ejected from the left ventricle. This occurs when the left ventricle is ejecting significantly but the recovery of pulmonary function lags behind. Herein, we describe the occurrence of “Harlequin effect” in the setting of central veno-arterial extracorporeal membrane oxygenation that ensues due to the persistence of right ventricular dysfunction in the presence of an interatrial communication. This results in right to left shunting at the atrial level while weaning the patient from extracorporeal life support.

Background:
An early warning tool, the Congenital Heart Assessment Tool (CHAT), was designed in 2012 to support parental preparation before discharge, enhancing understanding of their infant’s complex CHD, the signs of deterioration to look out for and to support decision-making at home. Acceptability and feasibility of the tool were tested during 2013–2015 in a single centre.
Aim of this project:To evaluate the wider implementation across four children’s cardiac centres of the CHAT for infants with complex CHD in the community setting.
Design:A four-centre collaborative mixed-methods quality improvement project funded by The Health Foundation, during 2016–2018. A plan, do, study, act cycle of improvement was employed. This article reports on the planning phases, creation of a modified tool (CHATm); and the implementation phases, including retrospective case note review using CHATm; tabletop simulation exercise using CHATm and clinical implementation of CHATm.
Results:Key findings included the benefit of using CHATm simulation for practitioners; the effectiveness of CHATm in predicting amber and red triggers, indicating parental actions and escalation of concerns to professionals. Parents using CHATm found it enhanced knowledge in preparation for going home, supported decision-making, and discussions with health care professionals.
Conclusion:Using the CHATm clinically identified the need to develop a structured model of assessment of parental suitability for home-monitoring programmes. A robust and nationally agreed training programme for all staff using CHATm was recommended to ensure successful and complete implementation in practice.

Objective:
We aimed to evaluate the efficacy of combined (ibuprofen+paracetamol) medical therapy in cases of persistent haemodynamically significant patent ductus arteriosus that are resistant to standard medical monotherapy (ibuprofen and/or paracetamol) in this retrospective multi-centre study.
Methods:The combined therapy included the administration of 15mg/kg/dose of paracetamol every 6 h for 3 days and ibuprofen at an initial dose of 10mg/kg/dose followed by 5 mg/kg/dose every 24 h. After 2 days following the administration of the last dose, the researchers evaluated the efficacy of combined treatment by conducting an echocardiographic examination.
Results:Of all 42 patients who received combined therapy, 37 (88.1%) patients exhibited closure of the haemodynamically significant patent ductus arteriosus without requiring surgical ligation. Patients who did not respond to combined therapy had a higher mean birth weight and gestational age compared to those who responded (p < 0.05).
Conclusion:The researchers believe the success of ibuprofen and paracetamol in haemodynamically significant patent ductus arteriosus treatment may be due to their synergistic efficacy and inhibition of the prostaglandin synthesis pathway through different enzymes. The results of our retrospective trial suggest that combination therapy with paracetamol and ibuprofen can be attempted when monotherapy is unsuccessful in treating haemodynamically significant patent ductus arteriosus, especially in centres without a surgical department.

Background:
In the absence of randomised trials for paediatric multisystem inflammatory syndrome temporally associated with SARS-CoV2 (PIMS-TS), optimal management of PIMS-TS-patients remains somewhat uncertain. We aimed to evaluate the practicability of consensus diagnostic/therapeutic pathways in a real-life German hospital setting.
Methods:All children treated for PIMS-TS (February to November, 2021) at the Childrens’ Hospital Kassel were analysed retrospectively. Patients were treated according to local PIMS-TS standardised operating procedure based on the Swiss and UK consensus statements
Results:Eleven patients treated for PIMS-TS were included in this study (female:male = 2.1:1). According to the categories of the Swiss and UK consensus statements, 36% were uncomplicated hyperinflammation, 36% Kawasaki-like and 27% shock-like disease. Local estimated incidence was 0.92/1000 Covid-19 cases in children aged 4–15 years. Significant inter-group differences in laboratory parameters were found: BNP was highest in shock-like presentation compared to Kawasaki-like and uncomplicated hyperinflammation (median 954 (668–1491) versus 213 (173–934) versus 80 (5–257) ng/l, p = 0.02), whereas troponin was highest in Kawasaki-like, followed by shock-like presentation and uncomplicated hyperinflammation (median 34.7 (27.5–58.4) versus 19.1 (14.1–23.4) versus 1.9 (1.9–16.4) ng/l, p = 0.02). Patients with shock-like presentation needed circulatory resuscitation in the paediatric ICU. All patients received standardised operating procedure-based therapy and were discharged home after a medium of 7.4 days.
Conclusion:The Swiss and UK consensus statements on the management of PIMS-TS proved very valuable in a real-life clinical setting, facilitated early categorisation, and initiation of specific therapy, possibly improving the outcome. Additional randomised trials are necessary to further improve the management of PIMS-TS

Background:
Despite advances in medical care, we still come across pregnancy in Eisenmenger syndrome. Eisenmenger syndrome represents the severe end of the spectrum for disease in pulmonary artery hypertension associated with CHD. Due to very high maternal and perinatal morbidity and mortality, pregnancy is contraindicated among these women. Current guidelines also recommend that the women who become pregnant should opt for early termination of pregnancy. Here, we present a case series of 11 women of Eisenmenger syndrome and their pregnancy outcome.
Methods:It was a retrospective analysis of 12 pregnancies among 11 women with Eisenmenger syndrome who were managed in a tertiary care referral centre of Northern India.
Results:The mean age of these women was 28 ± 4 years (range 22 to 36 years). Almost 80% of them (9/11) were diagnosed with Eisenmenger syndrome during pregnancy. The commonest cardiac lesion was Ventricular Septal defect (54.5%) followed by Atrial Septal defect (27.3%) and Patent Ductus arteriosus (9.1%). Only three women opted for medical termination of pregnancy, rest eight continued the pregnancy or presented late. Pregnancy complications found include pre-eclampsia (50%), abruption (22%), and fetal growth retardation (62.5%). There were three maternal deaths (mortality rate 27%) in postpartum period.
Conclusion:This case series highlights the delay in diagnosis and treatment of CHD despite improvement in medical care. Women with Eisenmenger syndrome require effective contraception, preconceptional counselling, early termination of pregnancy, and multidisciplinary care.

Background:
Right ventricular outflow tract intervention spans transcatheter, surgical, or hybrid pulmonary valve replacement methodologies. Standardised pre-procedure workup includes cardiac MRI to identify an intended valve site (landing zone). Our institutional practice includes measurement of the right ventricular outflow tract perimeter (circumference) of this site in end-systole. Our primary aim was to compare patients by their perimeter values to the palliative interventions performed (transcatheter versus surgical/hybrid methodologies).
Methods:Retrospective review of patients undergoing pulmonary valve replacement from January 2017 to 2021. We performed perimeter measurements at the intended valve site on advanced imaging; the outcomes of interventions were outlined via descriptive and statistical analyses.
Results:A total of 37 patients underwent pulmonary valve replacement that met study criteria – 21 transcatheter, 7 surgical, and 9 hybrid. Median age at intervention was 26 years (range 8–70). The mean end-systolic perimeter of the transcatheter cohort was 88.9 ± 8.7 mm and in the surgical/hybrid cohort measured 106.6 ± 7.5 mm. For the transcatheter cohort, the median “circularised” diameter derived from the perimeter measurement (divided by π) was 27.7 mm (range 24.3–32.4). Notably, this correlated (r = 0.93, p < 0.01) with the median diameter of the narrowest region during actual transcatheter right ventricular outflow tract balloon sizing (lateral imaging) of 27.1 mm (range 23.2–30.1).
Conclusions:Right ventricular outflow tract perimeter measurement to determine circularised diameter is useful in planning pulmonary valve replacement in terms of candidacy of transcatheter versus the need for a surgical/hybrid approach. The circularised diameter correlates with transcatheter right ventricular outflow tract balloon sizing.

Objective:
Joint programmes are an alternative model that may aid in improving congenital cardiac surgery outcomes while avoiding the potential resource and accessibility challenges that could result from regionalisation. This study aims to characterise current joint programmes, identify factors that are associated with joint programme success and failure, and gauge attitudes within the profession regarding joint programmes as an alternative.
Methods:A multiple choice survey with 23 standard questions for all programmes and additional 42 additional questions for each participant hospital in a joint programme was addressed to paediatric cardiac surgeons in the United States of America. Questions were designed to qualitatively and quantitatively characterise congenital cardiac surgery joint programmes.
Results:Of the 34 unique congenital cardiac surgery programmes identified in this survey, 14 have participated in a joint programme and 50% of those joint programmes existed for more than 10 years. Most joint programmes (86%) participate or participated in a model where the hospital participants are engaged in a “mother–daughter” relationship in both perception and case volume distribution. In three out of four defunct joint programmes, there were case complexity limitations placed on partner institutions, but the now independent partner institutions operate with no limitation on complexity. Most (71%) hospital participants in a joint programme felt that the joint programme produced better outcomes than two separate programmes; however, among those who participate or have participated in a joint programme, only 18% felt that joint programmes were the optimal model for delivery of congenital cardiac surgical care.

Purpose:
Systemic-to-pulmonary shunts are used as a source of pulmonary blood flow in palliated Congenital Heart Disease in neonates and young infants. Shunt thrombosis, often requiring shunt interventions during index hospitalisation, is associated with poor outcomes. We hypothesised that extensive use of perioperative pro-coagulant products may be associated with shunt thrombosis.
Methods:Children (≤18 years) undergoing systemic-to-pulmonary shunts with in-hospital shunt reinterventions between 2016 and 2020 were reviewed retrospectively. Perioperative associations to shunt thrombosis were examined by univariate logistic regression and Wilcoxon rank sum tests as appropriate. Cox and log transformed linear regression were used to analyse postoperative ventilation duration, length of stay, and cost.
Results:Of 71 patients requiring in-hospital shunt intervention after systemic-to-pulmonary shunts, 10 (14%) had acute shunt thrombosis, and among them five (50%) died. The median age was four (interquartile range: 0-15) months. There were 40 (56%) males, 41 (58%) had single ventricle anatomy, and 29 (40%) were on preoperative anticoagulants. Patients with acute shunt thrombosis received greater volume of platelets (p = 0.04), cryoprecipitate (p = 0.02), and plasma (p = 0.04) postoperatively in the ICU; experienced more complications (p = 0.01) including re-exploration for bleeding (p = 0.008) and death (p = 0.02), had longer hospital length of stays (p = 0.004), greater frequency of other arterial/venous thrombosis (p = 0.02), and greater hospital costs (p = 0.002).
Conclusions:Patients who develop acute shunt thrombosis receive more blood products perioperatively and experience worse hospital outcomes and higher hospital costs. Future research on prevention/early detection of shunt thrombosis is needed to improve outcomes in infants after systemic-to-pulmonary shunt surgery.

Background:
Paediatric residents are often taught cardiac anatomy with two-dimensional images of heart specimens, or via imaging such as echocardiography or computed tomography. This study aimed to determine if the use of a structured, interactive, teaching session using heart specimens with CHD would be effective in teaching the concepts of cardiac anatomy.
Methods:The interest amongst paediatric residents of a cardiac anatomy session using heart specimens was assessed initially by circulating a survey. Next, four major cardiac lesions were identified to be of interest: atrial septal defect, ventricular septal defect, tetralogy of Fallot, and transposition. A list of key structures and anatomic concepts for these lesions was developed, and appropriate specimens demonstrating these features were identified by a cardiac morphologist. A structured, interactive, teaching session was then held with the paediatric residents using the cardiac specimens. The same 10-question assessment was administered at the beginning and end of the session.
Results:The initial survey demonstrated that all the paediatric residents had an interest in a cardiac anatomy teaching session. A total of 24 participated in the 2-hour session. The median pre-test score was 45%, compared to a median post-test score of 90% (p < 0.01). All paediatric residents who completed a post-session survey indicated that the session was a good use of educational time and contributed to increasing their knowledge base. They expressed great interest in future sessions.
Conclusion:A 2-hour hands-on cardiac anatomy teaching session using cardiac specimens can successfully highlight key anatomic concepts for paediatric residents.

Objectives:
We present the short-term results of an alternative method in stage 1 surgery for hypoplastic left heart syndrome.
Methods:Data of 16 consecutive patients who were treated with the novel method in our clinic between February 2019 and March 2021 were analysed retrospectively. Preoperative data and postoperative follow-up were recorded.
Results:Of the 16 operated patients, 12 were diagnosed with hypoplastic left heart syndrome, while four were diagnosed with hypoplastic left heart syndrome variants. Seven patients died during early postoperative period. One patient died at home waiting stage 2 surgery. Three patient underwent stage 2 surgery. Pulmonary artery reconstruction was performed in one patient due to left pulmonary artery distortion.
Conclusions:We believe that our method can be an effective alternative in the surgery of hypoplastic left heart syndrome and its variants. It is hoped that with increasing number of studies and more experience better outcome will be achieved.
