Mitral valve insufficiency is treated by introducing an expansible device such as a balloon bearing a an ultrasonic transducer into the heart so that the transducer is positioned adjacent the mitral annulus but spaced from the mitral annulus, and actuating the transducer to heat the mitral annulus, denature collagen in the annulus and thereby shrink the annulus.
