Abstract：
Mitral valve surgery (MVS), with repair preferred to replacement, is a common procedure for the treatment of severe primary mitral regurgitation related to leaflet prolapse. Structural complications after MVS include left ventricular outflow obstruction, paravalvular leak and atrial septal defect. Intraoperative transoesophageal echocardiography and predischarge transthoracic echocardiography (TTE) specifically screen for these complications. Ventricular septal defect (VSD), a known complication after aortic valve surgery, is rarely reported after MVS. Recently, unsuccessful valvuloplasty prior to replacement was suggested as a risk factor. We present such a case and explore mechanisms with advanced cardiac imaging. In this case, the patient was found to have an elongated membranous septum that likely predisposed her to septal injury. Finally, we provide guidance on specific transoesophageal/transthoracic echocardiography views to avoid a missed diagnosis.
摘要：
二尖瓣手术（MVS），维修优于更换，是治疗与小叶脱垂相关的严重原发性二尖瓣返流（MR）的常用方法。MVS后的结构性并发症包括左心室流出道梗阻，瓣周漏和房间隔缺损。术中经食管超声心动图（TEE）和出院前经胸超声心动图（TTE）专门筛查这些并发症。室间隔缺损(VSD),主动脉瓣手术后已知的并发症，在MVS之后很少报道。最近,置换前瓣膜成形术不成功被认为是一个危险因素.我们提出了这种情况，并探索了先进的心脏成像机制。在这种情况下,患者被发现有一个细长的膜隔膜，可能易患间隔损伤。最后,我们就特定的TEE/TTE观点提供指导,以避免漏诊.
