[Problems in estimating the severity of aortic regurgitation by pulsed Doppler echocardiography: with special reference to its distribution pattern].

Abstract

We categorized the findings of aortic regurgitation (AR) by aortography (AOG) into the following four types, and compared them with the corresponding findings obtained by pulsed Doppler echocardiography (PDE) in 30 patients, and assessed the ability of PDE to observe the distribution of an aortic regurgitant flow. Type 1: A wide regurgitant jet distributed… (More)
