Twelve patients with endomyocardial fibrosis with angiographic and/or histologic corroboration were studied with Doppler echocardiography with the purpose of describing the echocardiographic features and identify the affected sites. The average age was 41 years (range 16 to 59 years), 2 men and 10 women. Three patients (25%) had isolated right ventricular involvement, one patient (8%) left ventricular, 8 patients (66%) both ventricular. Our Doppler echocardiographic findings were: right atrium enlargement (91%), right ventricle outflow dilatation (83%), paradoxical septal motion (83%), left atrial enlargement (33%), mitral and tricuspid valve prolapse (50%), pericardial effusion (41%), mitral regurgitation (75%), tricuspid regurgitation (100%), apex obliteration (50%) and a restrictive type flow pattern (50%). Doppler echocardiography is a useful method for the diagnosis of endomyocardial fibrosis, the finding of normal or small ventricles associated with apex obliteration and enlarged atria, mitral or tricuspid regurgitation and a restrictive type flow pattern are characteristics of this disease. In our population, the isolated or predominantely right ventricular involvement is the most common finding as it represented 83% of the cases.
对12例经血管造影和/或组织学证实的心肌内膜纤维化患者进行了多普勒超声心动图研究，目的是描述超声心动图特征并确定受累部位。平均年龄为41岁（范围16至59岁），男性2例，女性10例。3例患者（25%）仅右心室受累，1例患者（8%）左心室受累，8例患者（66%）双心室受累。我们的多普勒超声心动图检查结果如下：右心房增大（91%）、右心室流出道扩张（83%）、室间隔矛盾运动（83%）、左心房增大（33%）、二尖瓣和三尖瓣脱垂（50%）、心包积液（41%）、二尖瓣反流（75%）、三尖瓣反流（100%）、心尖闭塞（50%）以及限制性血流模式（50%）。多普勒超声心动图是诊断心肌内膜纤维化的一种有用方法，心室正常或较小但伴有心尖闭塞、心房增大、二尖瓣或三尖瓣反流以及限制性血流模式是该疾病的特征。在我们的研究人群中，仅右心室受累或主要为右心室受累是最常见的发现，占病例的83%。
