风心病各瓣膜病损率的分析(107例二维,多普勒超声心动图分析)

Valvular lesion frequency in rhumatic heart disease: Analysis of echocardiograms of 107 patients

现有风心病瓣膜病损率的统计多源于尸检和临床调查。本文应用二维、多普勒超声心动图统计了107例门诊风心病患者的瓣膜病损率,结果与以前的统计有所不同。瓣膜损害以联合瓣膜病变为主,占67.3％。而单瓣膜损害仅占32.7％,明显低于以前的统计结果。三尖瓣狭窄的发生率高于以前的统计结果。联合损害的主要形式是二尖瓣狭窄和关闭不垒合并主动脉瓣病变,其中以二尖瓣狭窄为主,为重。而二尖瓣关闭不全,主动脉瓣关闭不全或狭窄多为伴随的轻度病变。

The statistics about the valvular lesion frequency in rhumatic heart disease available at present come mainly from data of autopsy, angioqraphy and physical examinations. They are inaccurate. Echocardiography is considered the best modality for diagnosis of valvular disease. To investigate the exact frequency of rhumatic valvular lesion, 107 patients were examined by echocardiography. The results showed: 1. 67.3% of valvular lesions are combined, only 32.7% are single; 2, the commonest pattern of combined valvular lesion is mitral stenosis and requrgitation plus aortic regurgitation, the mitral stenosis usualy being predominant, while the mitral and aortic regurgitation of mild to moderate severity; 3, incidence of tricuspid stenosis is higher than that of previous results.
