Acquired coronary artery fistulae after right ventricular myotomy and/or myomectomy for congenital heart disease

We conclude that coronary artery fistulae may develop in patients undergoing right ventricular surgery and can be diagnosed during early postoperative echocardiographic evaluation. The most common site of drainage is the right ventricle. Careful imaging and color Doppler examination are needed to accurately assess postoperative patients for such fistulae. Finally, further echocardiographic follow-up is needed in order to determine the long-term consequence of these fistulae, with special attention to right ventricular volume and function.
