摘要
To assess the importance of atrial contribution to left ventricular filling in mitral stenosis, Doppler echocardiography war performed in 31 patients with mitral stenosis and sinus rhythm before(all patients) and after (15 patients) percutaneous mitral balloon valvuloplasty. Percent atrial contribution was derived from the ratio of atrial velocity-time integral (VTI) to total mitral VTL.The percent atrial contribution correlated closely with mitral valve area (r=0.91, P<0.001) and was inversely related to mean pressure gradient across the mitral valve orifice (r= -0.68, P<0.01). The study indicates that the degree of mitral stenosis exeris a great effect on the importance of a trial contribution to left ventricular filling in patients with mitral stenosis and sinus rhythm.
