心内膜心肌纤维化的主要特点为心内膜以及较小程度上心肌的纤维组织形成,使心室部分闭塞,减少心室的扩张能力,阻碍心室充盈。纤维化通常位于心尖,向流入道延伸,腱索常受累而产生二尖瓣及/或三尖瓣返流。本文报道心内膜心肌纤维化患者的手术前后所见。患者女性6例,男性1例,平均35岁(19～52岁)。4例因严重右心衰竭,2例因严重的二尖瓣返流,1例因双心室心力衰竭而入院。心功能5例为Ⅲ级,2例为Ⅳ级。7例中有4例用手术治疗,其中3例主要为左室纤维化伴中至重度二尖瓣返流者,
Endocardial myocardial fibrosis, the main features of the endocardium and to a lesser extent the formation of myocardial tissue, the part of the ventricular occlusion, reduce ventricular dilatation, hinder ventricular filling. Fibrosis is usually located at the apex, extending to the inflow tract, and tendons are often involved to produce mitral and / or tricuspid regurgitation. This article reports endocardial myocardial fibrosis seen in patients before and after surgery. Six patients were female and one was male, with an average age of 35 (19-52 years). Four patients were hospitalized for severe right heart failure, two for severe mitral regurgitation, and one for biventricular heart failure. 5 cases of cardiac function grade Ⅲ, 2 cases of grade Ⅳ. Four of the seven cases were treated surgically, three of whom were predominantly left ventricular fibrosis with moderate to severe mitral regurgitation,
