Abstract

Anomalous papillary muscle insertion directly into the surface of the mitral valve leaflet is rare, especially in a subject without apparent evidence of hypertrophic cardiomyopathy. We present a case of this isolated congenital malformation producing two hemodynamic sequelae of dynamic left ventricular outflow tract obstruction and severe mitral regurgitation.

摘要

乳头肌异常直接插入二尖瓣瓣叶表面的情况罕见，尤其是在没有明显肥厚型心肌病证据的患者中。我们报告了这样一例孤立性先天性畸形病例，该病例产生了动态左心室流出道梗阻和严重二尖瓣反流这两种血流动力学后遗症。
