Abstract

Coronary artery fistula (CAF) and noncompaction of the ventricular myocardium (NCVM) result from obliteration or compact failure of the intramyocardial trabecular sinusoids to form a ventricular cavity wall. The draining site of a right coronary artery (RCA) fistula may usually be the right ventricle, right atrium, or pulmonary artery. An RCA aneurysm with a fistula to the left ventricle is rare. We report a patient with an RCA aneurysm with a fistula to the left ventricle coexisting with NCVM. The patient's condition was diagnosed by echocardiography and contrast-enhanced multidetector computed tomography.
