Advances in surgical technique and postoperative care have resulted in substantial improvement in the operative mortality after repair of atrioventricular canal defects. However, significant late morbidity and the need for reoperation complicate the medium and long-term results in these patients. Left atrioventricular valve regurgitation, residual or recurrent intracardiac shunting, and subaortic stenosis are the principle causes of late morbidity after repair of complete and partial atrioventricular canal defects. This article describes the incidence and etiology of these complications, as well as the methods of diagnosis and management.
手术技术和术后护理的进步已使房室管缺损修复术后的手术死亡率有了显著改善。然而，严重的晚期并发症以及再次手术的需求使这些患者的中长期治疗结果变得复杂。左房室瓣反流、残余或复发性心内分流以及主动脉瓣下狭窄是完全性和部分性房室管缺损修复术后晚期并发症的主要原因。本文描述了这些并发症的发生率和病因，以及诊断和处理方法。
