Coronary artery fistula detected by 64-slice multidetector computed tomography: case report.

Coronary artery fistula (CAF), a rare anomaly of a coronary artery, is defined as an anomalous communication between a coronary artery and a cardiac chamber or vessels. Coronary angiography remains the main modality for diagnosing CAF. We present a case of fistulous communication between the left anterior descending coronary artery and the main pulmonary artery. The exact anatomy of the fistula was demonstrated by 64-slice multidetector computed tomography (MDCT). Surgical ligation on a beating heart was carried out. Intraoperative Doppler flow detection was used to evaluate the shunt of the CAF. We prefer MDCT as a new diagnostic modality to provide the detailed anatomy of a CAF.
