title: Unusual position of a prosthetic mitral valve.
abstract: Extensive calcification of the mitral annulus in patients who require mitral valvereplacement presents a significant challenge to the surgeon. Several techniques, includingdebridement of the calcium, reconstruction of the annulus, and insertion of the prosthesis in a locationother than the annulus, have been used in such patients. We report the echocardiographictechniques used to evaluate the case of a woman with an unusually positioned prosthetic mitralvalve.
