[Dynamic echocardiography in mitral insufficiency].
Mitral insufficiency can have a dynamic character, correlating to an intermittent increase in the area of the regurgitant orifice and the regurgitant volume. Among the various stress methods, echocardiography during effort on a bicycle in the semisitting position appears to be the technique of choice for evaluating this dynamic character. Thanks to the improvement of the Doppler signal quality, quantification of the regurgitant volume variations can be obtained in a reproducible manner at rest and during effort by applying the "PISA" method.
