Coronary artery fistula (CAF) is a rare congenital anomaly in which a communication is present between a coronary artery and cardiac chamber. Conventional coronary angiography is an invasive and expensive procedure, and cannot provide three-dimensional data. ECG gated multidetector CT (MDCT) is useful for non-invasive evaluation of coronary artery fistulae. Objectives: In this paper, we describe ten post-closure cases of coronary artery fistulae. The aim of this study is to demonstrate the effectiveness of 128 slice-MDCT in demonstrating the precise anatomy and post closure follow-up of coronary artery fistula. Methods: 10 pediatric subjects underwent MDCT as well as conventional coronary angiography. Good quality images were obtained in all patients to analyze the coronary artery fistulae and their anatomic course. Results: MDCT not only provided precise details of post closure CAF but also clearly delineated anatomy of other coronary arteries. Catheter-related risks like bleeding at puncture site, hematoma formation were completely eliminated. Advances in Knowledge: MDCT may provide additional precise details of CAF. It also eliminates minor as well as more serious complications of catheter angiography and a small but definite incidence of mortality. The procedure is carried out as an outpatient procedure. Thus, MDCT is considered as a good alternative to echocardiography and coronary angiography for diagnosis as well as follow-up of CAF. [Patel D NJIRM 2014; 5(5):82-89]
