An iatrogenic ventricular septal defect (VSD) after aortic valve replacement is rare, but represents a significant complication. Repeat surgery to repair such a defect carries a high surgical risk. The transcatheter approach (either transvascular or transapical) could be considered as an alternative to open chest surgery. We describe the successful transcatheter closure of an iatrogenic VSD with an Amplatzer membranous VSD occluder in a patient with previous combined mitral and aortic mechanical valve replacements. The device was implanted through a CarboMedics mechanical valve in the aortic position.
主动脉瓣置换术后医源性室间隔缺损（VSD）较为罕见，但却是一种严重的并发症。再次手术修复此类缺损手术风险很高。经导管介入方法（经血管或经心尖）可被视为开胸手术的替代方案。我们描述了一例曾接受二尖瓣和主动脉瓣机械瓣联合置换术的患者，使用Amplatzer膜周部室间隔缺损封堵器成功经导管封堵医源性室间隔缺损的病例。该装置通过置于主动脉位置的CarboMedics机械瓣植入。
