Patients with common atrioventricular valve( CAVV) regurgitation are at increased risk of mortality and adverse outcomes during single ventricle palliation. CAVV repair is one of the most challenging techniques in pediatric cardiac surgery. Especially in patients who require CAVV repair before Glenn operation have the complicated valve anatomy and sometimes need repeat valve surgery. Several techniques of CAVV repair include annuloplasty, commissuroplasty, cleft closure, edge-to-edge repair, and bivalvation. Prosthetic valve replacement for uncontrollable CAVV regurgitation in patients with single ventricular physiology is the last available option entailing a moderately high risk of death, valve dysfunction, and redo valve replacement.
患有共同房室瓣（CAVV）反流的患者在单心室姑息治疗期间死亡和出现不良结局的风险增加。CAVV修复是小儿心脏手术中最具挑战性的技术之一。特别是那些在格林手术前需要进行CAVV修复的患者，其瓣膜解剖结构复杂，有时还需要再次进行瓣膜手术。CAVV修复的几种技术包括瓣环成形术、交界切开术、裂口闭合术、边缘对边缘修复术和双瓣化术。对于单心室生理的患者，因CAVV反流无法控制而进行人工瓣膜置换是最后的选择，这会带来中度较高的死亡、瓣膜功能障碍和再次瓣膜置换风险。
