The operative results of this anomaly is generally acceptable. Between 1978 and 1982, 32 patients with PAVC underwent intracardiac repair. Two operative deaths occured in 41 and 42 years old patients who were in NYHA calss 4 preoperatively. Postoperative mitral insufficiency was either nil or mild except in one patient with mitral valve prolapse which was left unrepaired.
2. Complete Atrioventricular Canal Defect (CAVC)
Our operative procedures for th repair of CAVC are as follows, 1) all of accessory chordae are cut off and the bridging leaflet is incised into mitral and tricuspid components. 2) Ventricular septum, atrioventricular valve and atrial septum are construced with our designed endocardial cushion prosthesis (Dacron prosthesis with pericardial brim of 3-4 mm width in each side). Between 1978 and 1982, 20 patients with CAVC containing 16 infants less than 2 years old underwent intracardiac repair using this prosthesis. Thirteen patinets had no severe associated anomalies and only one death occurred in this group. Three patients were combined with tetralogy of Fallot (one died) and two patients with double outlet right ventricle (one died). The other two patients had either coarctation of the aorta (died) or interruption of the aortic arch (survived).
