收治室间隔缺损８８０例，６８例合并主动脉瓣关闭不全（７．７３％）。其中干下型室间隔缺损合并主动脉瓣关闭不全者４１例，膜周者２７例。５５例单纯行室间隔缺损修补术，１３例行室间隔缺损修补＋主动脉瓣成形术，无１例行主动脉瓣替换术。术后随访６月～１０ａ，无并发症，无近远期死亡，残余返流无１例较术前加重。多因素分析提示主动脉瓣关闭不全的程度、室间隔缺损的类型、瓣膜折叠的次数及术前心胸比率等对主动脉瓣成形术的疗效有着重要影响。
880 cases of ventricular septal defect were treated, 68 cases with aortic regurgitation (7.73%). Of which dry inferior ventricular septal defect with aortic regurgitation in 41 cases, 27 cases of membrane weeks. 55 cases of simple ventricular septal defect repair, 13 cases of ventricular septal defect repair + aortic valve angioplasty, 1 case of aortic valve replacement. All the patients were followed up for 6 months to 10 years. There was no complication, no immediate and long-term mortality, and none of the residual reflux was worse than preoperative. Multivariate analysis showed that the extent of aortic insufficiency, the type of ventricular septal defect, the number of valve folds and the preoperative cardiothoracic ratio had an important effect on the curative effect of aortic valve angioplasty.
