title: Early experience with the two patch technique for complete atrioventricular septal defect.
abstract: A total of 12 cases underwent repair of complete atrioventricular (AV) septal defect utilising the two-patch technique. There were 4 males and 8 females. The mean age at repair was 9.6 months (range, 3 to 49 months). The average weight was 5.4 kg (range, 3.5 to 13 kg). Five had associated patent ductus arteriosus. A Gore-Tex patch and glutaraldehyde preserved pericardium was utilised for the ventricular and atrial portions of the defects respectively in all patients. Four of these were done under hypothermic circulatory arrest. There were no intra-operative deaths. Early mortality comprised of 2 patients (2/12, 16.6%). One due to a pulmonary hypertensive crisis and the other to septicemia. The mean duration of ventilatory support was 62 hours (range, 24 to 192 hours). The mean duration of inotropic support was 57 hours (range, 24 to 192 hours). Primary repair of AV septal defects using the two-path of technique can be accomplished with a low early mortality in carefully selected patients.
