Complex forms of atrioventricular (AV) canal (C) such as; AVC with left ventricular outflow tract obstruction, tetralogy of Fallot with complete AVC, double orifice left AV valve, unbalanced complete AVC, and single ventricle patients with common AVC valve require careful preoperative planning and special techniques. This review will explore these technical modifications and outcomes for repair of complex variants of AVC. Optimal results will be achieved using an individually tailored approach that is guided by careful evaluation of the preoperative studies, precise operative technique, and intraoperative assessment of the reconstructed AV valve, as well as a willingness to re-intervene should the postoperative course not proceed as anticipated.
房室管（AVC）的复杂形式，如：伴有左心室流出道梗阻的AVC、完全性AVC的法洛四联症、双孔型左房室瓣、不平衡性完全性AVC以及具有共同AVC瓣的单心室患者，需要仔细的术前规划和特殊技术。本综述将探讨修复AVC复杂变体的这些技术改进和结果。通过精心评估术前研究、精确的手术技术、术中对重建房室瓣的评估以及在术后过程未按预期进行时愿意再次干预的个体化定制方法，将取得最佳结果。
