Right Coronary Artery Fistula to Left Ventricle Complicated with Huge Coronary Artery Aneurysm

Abstract

Congenital coronary artery fistula (CAF) with huge coronary artery aneurysm is a very rare condition. In this paper, we describe a 26-year-old asymptomatic male patient with right coronary artery (RCA) to the left ventricle fistula with a huge coronary artery aneurysm which was diagnosed by multidetector computed tomography and coronary angiography. The patient received surgical treatment for coronary artery after diagnosis. Both RCA and a giant aneurysm were excised; surgical closure of CAF and coronary artery bypass grafting were performed on this patient. Two months after surgery, the enlarged left ventricle returned to normal as evaluated by echocardiography.
