Intraoperative echocardiography (IOE), mostly done by transesophageal methods, provides an important means of accessing cardiac structure and function during cardiac and noncardiac surgery. The purpose of this study was to determine the role of IOE by identifying the frequency of the use of IOE during cardiac surgery, the rate of second pump operations determined by IOE findings, and the results of the operations.

Sixty-five patients (93 lesions) underwent cardiac surgery with the concomitant IOE done by a cardiologist in a single institution between March 1997 and October 1998. The data was collected retrospectively by reviewing the hospital records and IOE videotapes.

IOE was applied to 18.9% of total cardiac operations, primarily being used in MV surgery (48.4%). A pre-pump IOE was done in 2 cases and the post-pump procedure was done in the remainder. A second pump operation was performed in 4 cases (6.25%) and all of these were found to be successful after immediate re-operation.

IOE was primarily used in valve operations, particularly in procedures involving the mitral valve. IOE appears to be useful in determining the immediate results following cardiac surgery and may contribute to determining the prognosis of the patient.
