Intraoperative color flow Doppler echocardiography is uniquely suited to evaluate blood flow dynamics. By using direct epicardial imaging techniques, the efficacy of a surgical valvular repair can be instantaneously evaluated to assist the cardiac surgeon. If regurgitation is detected, surgeons may reexpose the valve and continue with further reconstruction or with replacement. The ability of color flow Doppler to assess surgical repairs prior to chest closure helps improve operative results.

Key Words: Doppler color flow mapping • intraoperative • valvular reconstruction
