Abstract
Conventional angiography is generally considered the standard procedure for diagnosis of coronary artery disease. With improvements in multidetector computed tomography (CT), CT coronary angiography (CTCA) is a new and rapidly emerging noninvasive imaging technique for coronary imaging. We report the three rarest types of congenital coronary artery fistulae detected by CTCA. CTCA is a practical tool for diagnosis of coronary artery anomalies and reveals the origin, course, termination, and connections of the fistula.
