The successful repair of three consecutive cases of tetralogy of Fallot associated with complete atrioventricular canal type C is reported. The correct preoperative diagnosis was established by right and left ventriculography. Operative repair in the first two patients involved division of both hemivalves above the crest of the ventricular septal defect and closure of the septal defects with a single large Dacron patch. In the third patient, the septal defects were closed with two separate patches. The undivided hemivalves were attached to the patches by interrupted sutures placed more to the right side of the midline, so that tricuspid tissue was used to reconstitute the mitral valve. Right ventricular outflow tract obstruction was relieved by infundibulectomy, pulmonary valvulotomy, and placement of a Darcon patch on the infundibulum in Cases 1 and 3. A valved tube was used in Case 2. Six months postoperatively, the condition of the patient is satisfactory. The first patient is receiving digitalis; the second, digitalis and diuretics; and the third patient is well without treatment.
报道了连续成功修复3例法洛四联症合并C型完全性房室通道的病例。通过左右心室造影术做出了正确的术前诊断。前两名患者的手术修复包括在室间隔缺损嵴上方分开两个半瓣膜，并用一块大的涤纶补片关闭室间隔缺损。在第三名患者中，室间隔缺损用两块分开的补片关闭。未分开的半瓣膜通过放置在中线右侧更多位置的间断缝线附着于补片上，以便用三尖瓣组织重建二尖瓣。在病例1和3中，通过漏斗部切除术、肺动脉瓣切开术以及在漏斗部放置一块涤纶补片缓解了右心室流出道梗阻。病例2使用了带瓣管道。术后6个月，患者情况令人满意。第一名患者正在接受洋地黄治疗；第二名患者接受洋地黄和利尿剂治疗；第三名患者未经治疗情况良好。
