Validation of a new Doppler-echocardiographic method for quantifying mitral regurgitation.


The noninvasive determination of severity of mitral regurgitation (MR) is often of major clinical importance. We performed simultaneous Doppler echocardiography and left ventricular angiography in 24 patients with MR, comparing a new Doppler echocardiographic technique with angiographic criteria for severity of MR. Angiographic severity was measured on a 1… (More)
