[Evaluation of prosthetic valvular regurgitation by color Doppler echocardiography].
Prosthetic valvular regurgitation was evaluated by color Doppler echocardiography in 107 patients with prostheses. Regurgitant jets were detected in 37 (35%) prostheses, 76% of them were transvalvular and 24% of them were perivalvular. The ratio of bioprostheses with increased intensity and transvalvular regurgitant jets increased parallel to the duration after replacement. Of those bioprostheses replaced more than 6 years, 23% developed regurgitation with a higher degree. Transvalvular regurgitation was detected in 25% of St. Jude Medical prostheses recently replaced, but the degree was low.
