【摘要】 目的分析二尖瓣置换术后左心室破裂的原因。方法作者经历2例二尖瓣置换术后左心室破裂,其中1例进行了尸体解剖,另外1例进行了术中探查。结合尸体解剖及术中探查的结果,以及二尖瓣置换术对心脏解剖的改变,分析左心室破裂的原因。结果 2例患者左心室破裂均排除了外科直接损伤,存在因解剖结构改变导致自发性破裂的因素。结论二尖瓣置换术后发生左心室破裂的原因与左心室结构改变有密切关系。更多还原

【Abstract】 Objective To analyze the causes of left ventricular rupture after mitral valve replacement in two cases.Methods Two patients with left ventricular rupture after mitral valve replacement were reported.One of them underwent autopsy and the other underwent intraoperative exploration.The causes of left ventricular rupture were analyzed according to the results of autopsy and intraoperative exploration,as well as the changes of cardiac anatomy after mitral valve replacement.Results The two patients with left ventricular rupture excluded direct surgical injury,and preoperative anatomical structure changes led to left ventricular rupture.Conclusion In the present report,the cause of left ventricular rupture after mitral valve replacement was closely related to the changes of left ventricular structure.更多还原
