Postsurgical coronary artery fistula after tetralogy of fallot repair

Abstract

Coronary artery fistula (CAF) are a major coronary anomaly which involve one or more coronary arteries abnormally communicating with one of the cardiac chamber or the great vessels adjacent to the heart. The incidence of CAF is 0.05-0.9% in general population and the majority are congenital. Acquired CAF are less common and may occur after cardiac surgery or catheterism, chest trauma or disease related. We present a case of a 6-month-old male infant who underwent intracardiac repair for Tetralogy of Fallot. During the immediate postsurgical period, a CAF from the left coronary artery to the right ventricle (RV) was detected. Spontaneous closure occurred one month after the initial diagnosis .
