Evaluation of unroofing procedure of anomalous origin of right coronary artery from left sinus of valsalva between aorta and pulmonary trunk by multidetector computed tomography.

An anomalous origin of a coronary artery is a rare congenital anomaly. Conventionally, the diagnosis of coronary artery anomalies is performed by coronary angiography. Currently developed multidetector computed tomography has permitted better definition of the coronary arteries, however. Multidetector computed tomography could be used effectively in the diagnosis and evaluation of the postoperative status of a patient with an anomalous origin of the right coronary artery from the left sinus of Valsalva between the aorta and pulmonary trunk.
