Intraoperative evaluation of valvular regurgitation: comparison of echocardiographic techniques.
Intraoperative echocardiography provides information on cardiac structure and function that is unobtainable from routine monitoring modalities.  Intraoperative imaging can be performed from the epicardial and/or transesophageal approach, and with the addition of contrast and/or color flow Doppler mapping, blood flow characteristics within the cardiac chambers can be visualized. The relative severity of regurgitation can be assessed before and after valvular surgery, and before the patient leaves the operating room, thereby facilitating successful valve repair or replacement.  Surgeon preference, equipment availability, and valvular pathology will determine which technique will be utilized.
