[Surgery of 56 patients having a partial atrioventricular septal defect].
Between January 1991 and December 2006, 56 patients having a partial atrioventricular septal defect (AVSD) were operated. The purpose of this retrospective study is to analyze the immediate and long-term results of the surgery by granting of the importance to two main problems which are the disturbances of the rhythm and the conduction and the residual mitral regurgitation (MR). The mean age of our patients is of 10 and a half years with a net feminine ascendancy. Ninety-three percent of the patients were in regular sinus rhythm. No case of complete atrioventricular block (AVB) was noted. The MR was of grade I in 28.5% of the cases, grade II in 60% of the cases and grade III and IV in 7.5% of the cases. The MR was mild in 4% of the cases. The correction was made under cardiopulmonary bypass (CPB) and consisted of a suture of the mitral cleft in most of the cases with lock of the ostium primum by a patch of pericardium. The perioperative mortality was 1,8% of the cases. The disturbances of the rhythm and the conduction were noted in 34% of the cases. All the patients were controlled with a mean follow-up of six years and seven months. The secondary mortality was nil. The MR, at mid-term follow-up, was mild in 78% of the cases. The partial AVSD is a congenital heart disease, the spontaneous evolution of which can be burdened by complications, notably the disturbances of the rhythm and the conduction, as well as the heart failure. This justifies a premature surgical repair.
