Abstract

Background: There has been a rekindling of interest in alternatives to conventional two patch technique for the repair of complete atrioventricular septal defect in infancy in the recent past. We applied the simplified single patch technique to 15 consecutive infants and herein report our intermediate term results.

Methods: Between March 1998 and September 2001, fifteen patients underwent repair of complete atrioventricular septal defect with this technique (mean age 6 months, mean weight 5.4 kg). Downs syndrome was present in 11 patients. Repair was done in all patients by direct suturing of the common atrioventricular valve leaflets to the crest of the ventricular septum irrespective of the size of the ventricular septal component. The cleft in the anterior mitral leaflet was closed in all patients. The atrial septal component was closed by a pericardial patch.

Results: There was no mortality. There were no pulmonary arterial hypertensive crises or heart block. The mean follow up was 13.2 months. One patient underwent mitral valve replacement after one year due to severe mitral regurgitation. The remaining fourteen patients had no significant mitral regurgitation, residual ventricular septal defect or left ventricular outflow tract obstruction on echocardiography.

Conclusion: Simplified single patch technique is an easily reproducible method for surgical repair of complete atrioventricular septal defect. It is less time consuming and minimises ischaemic time. Atrioventricular valve function is preserved and there is no incidence of obstruction to left ventricular outflow tract. The intermediate term results are encouraging.
