<p>Mitral valve insufficiency may be treated by introducing an energy emitter (50), such as an ultrasonic transducer, into the coronary sinus or esophagus of a mammal. The energy emitter (50) may be positioned, using imaging information obtained from the emitter unit, to emit energy to be absorbed substantially by the mitral annulus, so as to heat the mitral annulus for shrinking the annulus. Mitral valve insufficiency also may be treated completely non-invasively by targeted application of gamma radiation generated by a gamma knife (502), using imaging information and information indicating heart movement.</p> |
