Dobutamine stress echocardiography in anomalous left coronary artery.

The evaluation of left ventricular function with dobutamine stress echocardiography is described for the first time in a patient with anomalous left coronary artery from the pulmonary trunk during the preoperative and postoperative periods. This method demonstrated signs of myocardial ischemia that were not seen on the resting echocardiogram during the preoperative period and ventricular function recovery after surgical intervention.
