Gemella is a genus of Gram-positive bacteria found in the digestive tract of humans. They rarely cause systemic illness but have been recently implicated in several serious infections. We report infective endocarditis caused by Gemella bergeri in a 23-year-old with a bicuspid aortic valve status post-intervention in infancy.
There has been an increase in the use of extracorporeal membrane oxygenation for severe neonatal cardiac failure. However, the frequency of complications is high, particularly in preterm and low-birth-weight neonates. Herein, we present combination treatment with transcatheter balloon atrioseptostomy and bilateral pulmonary artery banding in a collapsed preterm neonate. This strategy can be an alternative to circulatory support using extracorporeal membrane oxygenation.
For most patients, adenoviruses cause few acute health concerns and are often self-limiting. Patients who are immunocompromised or immunosuppressed, however, are at risk for disseminated adenovirus and suffer high morbidity and mortality, without well-defined treatment options. We report the case of a 9-month-old boy who was successfully treated for disseminated adenovirus infection with intravenous immunoglobulin and cidofovir 3 months post heart transplant, tailored to serum adenoviral load and clinical response. We emphasise the importance of early identification, monitoring, and a potentially novel treatment in the paediatric cardiac transplant population with disseminated adenovirus infection.
Differentiation between post-operative inflammation and bacterial infection remains an important issue in infants following congenital heart surgery. We primarily assessed kinetics and predictive value of C-reactive protein for bacterial infection in the early (days 0–4) and late (days 5–28) period after cardiopulmonary bypass surgery. Secondary objectives were frequency, type, and timing of post-operative infection related to the risk adjustment for congenital heart surgery score.
Methods:
This 3-year single-centre retrospective cohort study in a paediatric cardiac ICU analysed 191 infants accounting for 235 episodes of CPBP surgery. Primary outcome was kinetics of CRP in the first 28 days after CPBP surgery in infected and non-infected patients.
Results:
We observed 22 infectious episodes in the early and 34 in the late post-operative period. CRP kinetics in the early post-operative period did not accurately differentiate between infected and non-infected patients. In the late post-operative period, infected infants displayed significantly higher CRP values with a median of 7.91 (1.64–22.02) and 6.92 mg/dl (1.92–19.65) on days 2 and 3 compared to 4.02 (1.99–15.9) and 3.72 mg/dl (1.08–9.72) in the non-infection group. Combining CRP on days 2 and 3 after suspicion of infection revealed a cut-off of 9.47 mg/L with an acceptable predictive accuracy of 76%.
Conclusions:
In neonates and infants, CRP kinetics is not useful to predict infection in the first 72 hours after CPBP surgery due to the inflammatory response. However, in the late post-operative period, CRP is a valuable adjunctive diagnostic test in conjunction with clinical presentation and microbiological diagnostics.
We report a case of thyroid storm precipitated by SARS-CoV-2 infection in an adolescent girl with a history of Graves disease and dilated cardiomyopathy. This case highlights that SARS-CoV-2 infection can potentially trigger a thyrotoxicosis crisis and acute decompensated heart failure in a patient with underlying thyroid disease and myocardial dysfunction even in the absence of multi-system inflammatory syndrome in children. We systematically reviewed the thyrotoxicosis cases with SARS-CoV-2 infection and described its impact on pre-existing dilated cardiomyopathy.
A young child presented with hepatomegaly, ascites and bradycardia in the setting of COVID-19. Permanent complete atrioventricular block and severe right heart failure were diagnosed. He was treated with surgical epicardial pacemaker implantation. This report is the first description of COVID-19-induced permanent complete atrioventricular block in a child.
A 12-year-old girl presented with fever and signs of systemic inflammation, and was found to have junctional tachycardia. She was subsequently diagnosed with Multisystem Inflammatory Syndrome in Children and treated with intravenous immunoglobulin and steroids, which led to resolution of the arrhythmia.
To compare patients treated for incomplete Kawasaki disease whose practitioners followed versus did not follow American Heart Association criteria and to evaluate the association of cardiology consultation with adherence to these guidelines.
Study design:
Single centre retrospective cohort study of patients <18 years old who received ≥1 dose of intravenous immunoglobulin for Kawasaki disease between 01/2006 and 01/2018. We collected demographics, clinical and laboratory data, coronary artery abnormalities, and cardiology consultation status. Patients treated for incomplete Kawasaki disease were divided into two groups based on adherence versus nonadherence to American Heart Association guidelines and compared by Wilcoxon rank sum test and chi-squared or Fisher’s exact test.
Results:
Of the 357 patients treated for Kawasaki disease, 109 (31%) were classified as incomplete Kawasaki disease. The American Heart Association algorithm for identifying patients with incomplete Kawasaki disease was followed in 81/109 (74%). Coronary artery abnormalities were present in 46/109 (42%) of the patients who were treated for incomplete Kawasaki disease. Cardiology consultation was more frequent in those fulfilling American Heart Association criteria for the diagnosis of incomplete Kawasaki disease versus those who did not fulfill criteria (76% versus 48%, p = 0.005).
Conclusions:
Over 25% of patients treated for incomplete Kawasaki disease did not meet American Heart Association guidelines. Guidelines were more frequently followed when the paediatric cardiology team was consulted. Consulting physicians with experience and expertise in the evaluation and management of incomplete KD should be strongly considered in the care of these patients.
This study was conducted to evaluate the persisting Covid-19-related symptoms of the cases included in our study and to assess their cardiac findings to determine the impact of Covid-19 on children’s cardiovascular health.
Methods:
In this study, 121 children between the ages of 0– and 18 with Covid-19 were evaluated based on their history, blood pressure values, and electrocardiography and echocardiography results. These findings were compared with the findings of the control group which consisted of 95 healthy cases who were in the same age range as the study group and did not have Covid-19. The results were evaluated using the statistics program, SPSS 21.
Results:
There was no significant difference between the study group and the control group in terms of age, weight, and body mass index. The clinical symptoms (chest and back pain, dizziness, headache, palpitation, fatigue, shortness of breath, loss of balance, coughing) of 37.2% of the cases persisted for at least 1 month after Covid-19 recovery. Statistically significant differences were found in systolic blood pressure, left ventricular ejection fraction, relative wall thickness, and tricuspid annular plane systolic excursion.
Conclusion:
The continuation of some cases’ clinical symptoms post-recovery indicates that long Covid infection can be observed in children. The fact that statistically significant differences were observed between the echocardiographic parameters of the study and control groups suggests that Covid-19 may have effects on the cardiovascular system. To shed light on the long Covid cases among children and the infection’s cardiac impacts, it would be beneficial to conduct more comprehensive studies on this matter.
We present a case of infective endocarditis caused by Streptococcus gordonii in an 11-year-old girl with Barlow’s mitral valve disease. The differential diagnosis of rheumatic carditis and infective endocarditis was difficult as the patient fulfilled the Jones criteria. Vegetation on the mitral valve which became evident later in course of the disease and positive blood culture allowed diagnosing “definite” infective endocarditis.
Hydatid disease is a zoonotic parasitic infection endemic in livestock-raising countries. Isolated cardiac hydatid cyst is a very rare disease, and chest pain, palpitations, cough, and dyspnoea are the most common presenting symptoms. Here a case of isolated cardiac hydatid cyst in a female patient with chest pain and electrocardiographic changes mimicking myocardial ischaemia is presented.
Acute myocarditis is a rare but potentially fatal disease. Endomyocardial biopsy and histologic examination are key to an accurate diagnosis. Despite being an uncommon cause, Influenza A and B viruses are a well-documented aetiology. Myocarditis may complicate about 0 to 10% of influenza virus infections (0.4 to 5% in paediatric cases). The clinical presentation varies widely, from ischemic-like chest pain to fulminant myocarditis with acute hemodynamic compromise, requiring mechanical circulatory support, with high mortality in the acute phase. We report a series of paediatric patients with myocarditis due to Influenza virus, to emphasize the importance of considering this uncommon aetiology.
To describe outcomes of acute coronavirus disease 2019 in paediatric and young adult patients with underlying cardiac disease and evaluate the association between cardiac risk factors and hospitalisation.
Study design
We conducted a retrospective single-institution review of patients with known cardiac disease and positive severe acute respiratory syndrome coronavirus 2 RT-PCR from 1 March, 2020 to 30 November, 2020. Extracardiac comorbidities and cardiac risk factors were compared between those admitted for coronavirus disease 2019 illness and the rest of the cohort using univariate analysis.
Results
Forty-two patients with a mean age of 7.7 ± 6.7 years were identified. Six were 18 years of age or more with the oldest being 22 years of age. Seventy-six percent were Hispanic. The most common cardiac diagnoses were repaired cyanotic (n = 7, 16.6%) and palliated single ventricle (n = 7, 16.6%) congenital heart disease. Fourteen patients (33.3%) had underlying syndromes or chromosomal anomalies, nine (21%) had chronic pulmonary disease and eight (19%) were immunosuppressed. Nineteen patients (47.6%) reported no symptoms. Sixteen (38.1%) reported only mild symptoms. Six patients (14.3%) were admitted to the hospital for acute coronavirus disease 2019 illness. Noncardiac comorbidities were associated with an increased risk of hospitalisation (p = 0.02), particularly chronic pulmonary disease (p = 0.01) and baseline supplemental oxygen requirement (p = 0.007). None of the single ventricle patients who tested positive required admission.
Conclusions
Hospitalisations for coronavirus disease 2019 were rare among children and young adults with underlying cardiac disease. Extracardiac comorbidities like pulmonary disease were associated with increased risk of hospitalisation while cardiac risk factors were not.
A term newborn, who underwent lotus birth, developed Staphylococcus lugdunensis sepsis and endocarditis on the 1st day of life. This case reports an uncommon pathogen known to cause destructive endocarditis in the adult and paediatric populations, causing endocarditis in a neonate. We speculate that lotus birth, an atypical birthing practice, may have contributed to the development of this infection.
Pulmonary aspergillosis associated with cyanotic congenital heart disease is a rare condition, which is known to have a poor prognosis. We report a case of a 21-year-old woman with truncus arteriosus and major aortopulmonary collateral arteries who underwent primary Rastelli procedure after thoracoscopic lobectomy for the management of progressive pulmonary aspergillosis.
Steroids are used in the treatment of acute rheumatic fever with moderate-to-severe carditis. Corticosteroids have several cardiovascular side affects that are more common in adults than in children. Corticosteroid-related bradycardia is a rarely seen side effect. Children with bradycardia following oral corticosteroid use are rarely reported previously. We present a child who developed bradycardia after oral corticosteroid treatment and concurrent Wolff–Parkinson–White pattern.
The most serious manifestation of rheumatic fever is carditis, as it can lead to chronic rheumatic heart disease. Neutrophil-to-lymphocyte ratio, platelet-to lymphocyte ratio and mean platelet volume have been accepted as novel indicators of the continuing inflammation that is correlated with the severity of valvular involvement in patients with rheumatic carditis.
Objective:
As a diagnostic study to investigate the correlation of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and mean platelet volume with the severity of carditis in children with rheumatic fever.
Methods:
This was a cross-sectional study at Sanglah Hospital, Bali. Data were collected retrospectively from medical records. Severity of carditis was characterised by a clinical, audible murmur during physical examination and demonstration of valvular involvement by echocardiography. Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and mean platelet volume were calculated from complete blood count. The correlation between parameters was assessed using Spearman’s correlation tests.
Results:
From January 2018 to December 2020, we found 45 cases admitted to Sanglah Hospital. Carditis was present in 40 (88.9%) subjects. Neutrophil-to-lymphocyte ratio had a strong positive correlation with severity of carditis (r = 0.66, p = 0.001), while platelet-to-lymphocyte ratio had a weak positive correlation with the severity of carditis (r = 0.23, p = 0.13) and mean platelet volume had a very weak negative correlation with the severity of carditis (r = −0.01, p = 0.95). Using a cut-off of 3.4, neutrophil-to-lymphocyte ratio predicted severe carditis with a sensitivity of 81.8% and specificity of 91.3%.
Conclusion:
There was a positive correlation between neutrophil-to-lymphocyte ratio and severity of carditis in children with rheumatic fever. Neutrophil-to-lymphocyte ratio might be used as a diagnostic tool to predict the diagnosis of carditis severity.
During the initial surge of the COVID-19 pandemic in the spring and summer of 2020, paediatric heart centres were forced to rapidly alter the way patient care was provided to minimise interruption to patient care as well as exposure to the virus. In this survey-based descriptive study, we characterise changes that occurred within paediatric cardiology practices across the United States and described provider experience and attitudes towards these changes during the pandemic. Common changes that were implemented included decreased numbers of procedures, limiting visitors and shifting towards telemedicine encounters. The information obtained from this survey may be useful in guiding and standardising responses to future public health crises.
Children with exposure to coronavirus disease 2019 in recent times (asymptomatic or symptomatic infection) approaching congenital heart surgery programme are in increasing numbers. Understanding outcomes of such children will help risk-stratify and guide optimisation prior to congenital heart surgery.
Objective:
The objective of the present study was to determine whether convalescent coronavirus disease 2019 children undergoing congenital heart surgery have any worse mortality or post-operative outcomes.
Design:
Consecutive children undergoing congenital heart surgery from Oct 2020 to May 2021 were enrolled after testing for reverse transcription-polymerase chain reaction or rapid antigen test and immunoglobulin G antibody prior to surgery. Convalescent coronavirus disease 2019 was defined in any asymptomatic patient positive for immunoglobulin G antibodies and negative for reverse transcription-polymerase chain reaction or rapid antigen test anytime 6 weeks prior to surgery. Control patients were negative for any of the three tests. Mortality and post-operative outcomes were compared among the groups.
Results:
One thousand one hundred and twenty-nine consecutive congenital heart surgeries were stratified as convalescence and control. Coronavirus disease 2019 Convalescent (n = 349) and coronavirus disease 2019 control (n = 780) groups were comparable for all demographic and clinical factors except younger and smaller kids in control. Convalescent children had no higher mortality, ventilation duration, ICU and hospital stay, no higher support with extracorporeal membrane oxygenation, high flow nasal cannula, no higher need for re-intubations, re-admissions, and no higher infections as central line-associated bloodstream infection, sternal site infection, and ventilator-associated pneumonia on comparison with coronavirus disease 2019 control children.
Conclusions:
Convalescent coronavirus disease 2019 does not have any unfavourable outcomes as compared to coronavirus disease 2019 control children. Positive immunoglobulin G antibody screening prior to surgery is suggestive of convalescence and supports comparable outcomes on par with control peers.
Purulent pericarditis occurs rarely in the current antibiotic era. We describe clinical and echocardiographic features of purulent pericarditis in a previously healthy child with influenza and community-acquired methicillin-resistant Staphylococcus aureus co-infection. The child was already on appropriate antibiotics and had a very subtle clinical presentation, with prominent abdominal symptoms. Timely surgical drainage led to complete recovery.
