Thrombotic coronary arterial occlusion, and myocardial infarction, are rare in the newborn. We report such a happening presenting shortly after birth with cardiogenic shock, no left ventricular output and a systemic circulation dependent on flow from a patent arterial duct.

We describe a complex case of obstruction of the left ventricular outflow tract in one of Dr. Noonan's original patients. Intraoperative findings revealed pathology at the valvar, subvalvar and supravalvar positions. Patients with Noonan syndrome are traditionally described as having right-sided cardiac pathology. Review of the literature revealed left-sided lesions to occur in a substantial number of these patients. We therefore suggest the routine employment of cardiac ultrasonography in all patients with Noonan syndrome with attention directed toward left-sided pathology, as well as the frequent pulmonary valvar pathology.

Reported here is an obstruction of the right ventricular outflow tract caused by a tuberculoma in a 15-year-old boy who presented with a ventricular septal defect. The obstruction was discovered at surgery and the tuberculous aetiology was only demonstrated histologically. To the authors' knowledge, this is the first report of a tuberculoma of the heart associated with congenital heart disease.

A child of a mother with maternal anti-Ro and anti-La antibodies presented antenatally with abnormal myocardial function, and was found to have a first degree heart block at birth. The extent of the abnormality in the conduction system progressed, with appearance of left bundle branch block in addition to further prolongation of PR interval. A pacemaker was implanted prophylactically, but patient has remained well, with no further deterioration in her atrioventricular conduction.

A child presented at birth with severe cyanosis. Echocardiography showed hypoplasia of the right heart with a right-to-left shunt at atrial level. A conservative approach was adopted initially, and the situation improved over a few months, with reversal of the atrial shunt. Surgery was successfully performed at 4 years of age after further echocardiography revealed a congenitally large Eustachian valve and an atrial septal defect.

Closure of atrial septal defects be means of intravenous catheterisation has been undertaken using a variety of devices as an alternative to surgical closure.1–5 We describe the first case, to the best of our knowledge, of infective endocarditis complicating a successful transcatheter closure. This highlights the potential risk of this procedure, and emphasises the need for appropriate antibiotic prophylaxis until complete endothelialization of the device has occurred.

An infant is described with congenitally corrected transposition and Ebstein's malformation. Banding of the pulmonary trunk had been previously performed because of a muscular ventricular septal defect. The patient underwent the double-switch procedure with the intention of unloading the morphologically right ventricle and the malformed tricuspid valve. This resulted in prompt postoperative functional and haemodynamic improvement.

Division of the morphologically left atrium is a rare abnormality, constituting around 0.1% of congenital heart disease. It may coexist with other cardiac abnormalities, and this association may obscure its recognition. We report an uncommon association with tricuspid atresia and discordant ventriculo-arterial connections, the latter dominating the clinical picture. Accurate diagnosis was made by transthoracic cross-sectional echocardiography, and the patient was referred to surgery without need for cardiac catheterisation.

Informed medical care, appropriate maternal and fetal monitoring, and cooperation among experienced obstetricians, anesthesists cardiologists, particularly during delivery and the early puerperium associated with psychological preparation of the mother, were the bases of the successful management of a pregnant 28-year-old woman at high risk because of the Eisenmenger reaction.

A 3-year-old patient is described with an unusual form of co-arctation due to hypoplasia of the transverse arch and fibromuscular dysplasia involving a long segment of the thoracic aorta. Surgical repair required resection of the aorta from the distal transverse arch to the mid-descending thoracic aorta, and replacement with a 16-mm Dacron interposition graft. This case demonstrates the importance of preoperative evaluation of the entire aorta in the presence of co-arctation due to fibromuscular dysplasia.

Described is a rare association in a patient with the heart in the left chest, namely pulmonary atresia with intact ventricular septum, fistulous coronary arterial connections, a right-sided aortic arch and an aorto-pulmonary collateral artery feeding one lung. The pulmonary arteries were non-confluent, with the right lung supplied by the right arterial duct originating from the under surface of the right-sided aortic arch, and the left lung supplied through the aorto-pulmonary collateral artery arising from the descending aorta. The surgical management is different in the setting of non-confluent pulmonary arteries.

The sequential segmental approach is now universally used in the diagnosis of congenital heart disease. Its utilization during fetal sonography has not been well described. In this review, we show how the fetal heart can be approached in a sequential segmental manner by using six basic sonographic views. The transverse view of the fetal upper abdomen is obtained to determine the arrangement of the abdominal organs, which, in most cases, provides the important clues to the determination of the atrial arrangement. The four-chamber view is obtained to evaluate the atrioventricular junctions. The views of the left and right ventricular outflow tracts are obtained to evaluate the ventriculoarterial junctions. The three-vessel view and the aortic arch view are obtained for the evaluation of the arrangement and size of the great arteries, which provides the additional clues to the diagnosis of the abnormalities involving the ventriculoarterial junctions and the great arteries. The standard protocol to acquire these six basic views is also introduced.

We report amiodarone-induced pulmonary toxicity in an 18-year-old who had undergone corrective surgery for tetralogy of Fallot 4 years earlier, and was treated with amiodarone because of recurrent malignant postoperative ventricular tachyarrhythmias. Toxicity was recognized on the basis of clinical features, chest X-ray, high-resolution contrast enhanced computerized tomography, and resolution of the findings subsequent to withdrawal of amiodarone and treatment with steroids. pulmonary toxicity due to amiodarone, as far as we know, has not been reported in children and young adults, and its occurence even in young adults requires wider appreciation.

The unusual case of an infant with aortic origin of the left pulmonary artery is presented. The patient developed a rare complication of lobar emphysema due to bronchial compression from the enlarged right pulmonary artery. Operative anastomosis of the left pulmonary artery to the pulmonary trunk was successful, with subsequent resolution of the lobar emphysema.

A 6-day-old male with interruption of the aortic arch at the isthmus (type A) had the typical phenotype of DiGeorge syndrome. There was also a doubly committed juxta-arterial ventricular septal defect and an unobstructed left ventricular outflow tract. Hypoplasia of the thymus was confirmed during a modified Blalock-Park operation. He had persistent hypocalcemia, and was susceptible to infection. He was subsequently revealed by the use of fluorescence in situ hybridization analysis to have 22q11.2 deletion. Interruption of the aortic arch at the isthmus is presumed to reflect abnormal fetal hemodynamics, and is considered a distinct pathogenetic entity from interruption between the left common carotid and subclavian arteries, the latter being the variant more frequently associated with DiGeorge syndrome. In our case, the 22q11.2 deletion likely played a major role in the etiology of the interrupted aortic arch.

The reentrant circuit of common atrial flutter is known to located in the right atrium between two anatomical barriers. Recent electrophysiologic studies have defined the tricuspid annulus as the anterior barrier, and the terminal crest and its continuation as the eustachian ridge as the posterior barrier. Construction of a bidirectional block to conduction between these two barriers by means of lesions created with radiofrequency current have been shown to be effective in ablating the flutter. We now find that surgical creation of such a block to conduction between the barriers by a simple modification of the atrial incision line is equally effective. In a 6-year-old boy, who was admitted to our hospital for closure of an atrial septal defect and treatment of sustained atrial flutter, the atriotomy was performed perpendicular to the terminal groove and extended towards the tricuspid annulus, placing some crythermal lesions between the end of the incision and the annuals. The special defect was closed using a Dacron patch. The child was free of arrhythmia both during the postoperative stay and over the initial three months of follow-up. We conclude that this simple modification of the atrial incision line provides cure of atrial flutter in children who require atriotomy for repair of congential cardiac anomalies. It may also be beneficial in preventing ‘incisional’ reentrant tachycardia.

We present a 14-year-old female with a massive aneurysm of the pulmonary trunk occurring secondary to bacterial endocarditis of the patent arterial duct. Echo Doppler imaging, magnetic resonance and angiography confirmed the diagnosis. On intermediate follow-up after surgical correction, the echo studies and cardiac catheterization disclosed no residual lesions. The patient is now asymptomatic.
