“…The interest of our study focuses on the fact that most of the main studies about partial AV septal defect [1][2][3][4] incorporated patients suffering from other associated cardiac anomalies such as aortic coarctation, pulmonary stenosis, ostium secundum IAC, double superior vena cava, anomalies of the venous return, or hypoplasia of the left ventricle. This is the first and largest series reporting of patients with an isolated partial AV septal defect and a large age-range.…”

“…Most of the authors [1,7,12] report several surgical procedures (suture or not of the septal commissure, annuloplasty, prosthetic or pericardial patch on the IAC) motivated by their own experience. All our patients were operated on using the same surgical technique (systematic closure of the septal commissure, dacron w patch on the IAC, drainage of the coronary sinus in the right atrium) over a long period.…”

The morbi-mortality of the isolated partial AV septal defect is primarily perioperative and is linked with the presence of an atypical form of the lesion. This atypical form was the main reason for reoperation for AV valve regurgitation. The AV valve replacement was associated with a high mortality and with the occurrence of complete AV block. Using a standardized technique, the AV septal defect can be repaired with excellent long-term clinical and echographic results.

A 4-year-old, 5.9-kg female Japanese Spitz presented with syncope and exercise intolerance. Echocardiography revealed an ostium primum atrial septal defect (ASD), a cleft mitral valve, mitral valve regurgitation (MR), and tricuspid regurgitation (TR) (velocity: 3.6 m/sec, pressure gradient: 52 mmHg), leading to a diagnosis of partial atrioventricular septal defect (AVSD) with moderate pulmonary hypertension (PH). Open-heart surgery using cardiopulmonary bypass was performed through right atriotomy. The cleft of the mitral valve was sutured with polypropylene and the AVSD was closed using an autologous pericardial patch fixed with glutaraldehyde. No postoperative pulmonary hypertensive crisis occurred. Shunting flow through the ASD, TR and PH had completely disappeared 2 months postoperatively; however, moderate MR persisted. The dog is still alive 5 years postoperatively without clinical signs.

“…on living patients over 20 years of age shows an erroneously favorable outcome, because deaths under 20 years of age were not included 24. Surgery comes close to restoring normal survival, but, as pointed out by McMullan et al,23 the results are less good for those operated on over 15 years of age, with larger hearts, or with more severe symptoms. Even so, those operated on over 15 years of age have a 90% survival over the next 18 years.…”

Reflections on the past, present and future of pediatric cardiology

SummaryAbout 1.5 million children are born each year world-wide with congenital heart disease. The nine most frequently occurring lesions are patency of the arterial duct (ductus arteriosus), atrial septal defect within the oval fossa, atrioventricular septal defect, ventricular septal defect, coarctation of the aorta, valvar pulmonary stenosis, valvar aortic stenosis, tetralogy of Fallot, and complete transposition. Their natural history is presented and compared with representative results of surgical treatment. Surgery has markedly improved the outcome for all these lesions, although almost no patients have been followed postoperatively for more than 25 years. Because congenital heart lesions are likely to consume an increasing proportion of cardiological resources in future years, the long-term future in this field rests with prevention of these lesions if at all possible. Recent advances in molecular and developmental biology, some of which are discussed, will certainly aid in diagnosis and may well bring the time at which prevention can be achieved closer to reality.
