不同原因所致二尖瓣脱垂超声,手术及病理对比分析

本文回顾性分析１６例不同原因所致二尖瓣脱垂超声心动图表现，结合手术及病理改变，评价超声诊断价值。除二尖瓣不同程度脱垂外，９例粘液样变性的瓣叶冗长、活动幅度增强，青少年与老年瓣膜厚度及瓣口面积有所不同。５例瓣膜感染性炎性病变中４例瓣叶不厚或瓣尖轻度增厚，见赘生物；另１例瓣膜增厚、严重变形、穿孔。以上１４例均有不同程度腱索延长、断裂。２例风湿性瓣膜病变的瓣叶增厚，部分钙化，１例无交界粘连，腱索延长

A Comparison Study of 2 DE,Surgery and Pathological Findings of Mitral Valve Prolapse Induced by Different Causes
