Intraoperative Assessment of Mitral Commissurotomy and Mitral Valve Replacement by Echocardiography
One of the newest applications of echocardiography is its use in the operating room as an aid to the surgeon in the immediate assessment of several types of cardiac surgery. Intraoperative echocardiographic analysis of mitral valve motion before and after surgery has become a routine method for evaluating mitral commissurotomy and mitral valve replacement. Placement of the sterile transducer directly on the heart clearly demonstrates both natural valve function and the degree of prosthetic ball or disc movement. Thus, by intraoperative echocardiographic assessment, valve dysfunction following mitral commissurotomy or prosthetic valve replacement can be detected, and the valve can be replaced immediately. Two cases illustrate the applications of intraoperative echocardiography in the evaluation of mitral valve repair and replacement.
