Surgical treatment of partial atrioventricular septal defect / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To summarize the experience of surgical treatments of partial atrioventricular septal defect in 60 patients.@*METHODS@#From April 1999 to April 2004, 60 patients of partial atrioventricular septal defect were operated. Fifty-eight patients were performed with suture of the cleft of mitral valve and the other 2 were given mitral valve replacement; For closure of primum ASD, 53 patients with pericardial patches and 7 with Dacron patches. Coronary sinus was baffled to left atrium with kirklin procedure in 35 cases and baffled to right atrium with McGoon procedure in other 25 cases. Correct the accompanying cardiac deformity at the same time.@*RESULTS@#The hospital mortality was 3.3% (2/60) due to low cardic output syndrome. The incidence rate of complete atrioventricular block was 8.00% (2/ 35) in the group with Kirklin procedure and 6.06% (2/25) in the group with McGoon procedure. There was no statistical significance between the 2 groups (P > 0.05). The follow-up was from 1 month to 5 years, and there was no late death. All cardiac function were improved except middle mitral regurgitation in 1 patient.@*CONCLUSION@#Reasonable operative design, refined procedures, avoiding damage to conducting bundles and proper perioperative management are the key points in improving theraeutic effect.
