Anomalous origin of the left anterior descending artery from the main pulmonary artery with multi-detector row computed tomography coronary angiography.

Anomalous origin of the left anterior descending artery from the main pulmonary artery is a rare congenital anomaly of the coronary artery. We present a case report of a 31-year-old male patient with anomalous origin of the left anterior descending artery from the main pulmonary artery that was diagnosed by multi-detector row computed tomography coronary angiography and correlated with conventional angiography. The results indicate that multi-detector row computed tomography plays an important role in the diagnosis of some rare coronary anomalies that conventional angiography cannot clarify.
