[Study of the etiologic mechanism of valvular regurgitation using Doppler echography]

Doppler echocardiography is currently the method of choice for diagnosing and determining the mechanism and etiology of valvular regurgitation. The recent introduction of transesophageal echo coupled with color Doppler has increased the value of these ultrasonic methods. The analysis of the valvular lesion should be particularly precise and accurate in severe mitral insufficiency because of the possibility of surgical valvuloplasty, the indications of which are now much broader than was the case at the beginning of the nineteen eighties.
