Abstract:
A 35-year-old male with exertional dyspnea was transferred to our hospital for evaluation of a diastolic murmur and cardiomegaly discovered by chest X-ray. Two-dimensional and Doppler echocardiographic studies revealed an aneurysmal dilation of the right coronary artery (RCA) and diastolic inflow from the RCA to the left ventricle (LV) through a myocardial defect 11 mm in diameter in the basal inferior LV wall. Coronary computed tomography angiography (CCTA) confirmed the presence of a giant RCA to LV fistula. Due to the risks for developing overt left heart failure and spontaneous rupture of the giant RCA, the RCA was obliterated surgically. Coronary-cameral fistulas are a rare congenital coronary artery anomaly. A fistula between the coronary artery and LV, especially when combined with coronary artery aneurysm, is a rare occurrence in the literature. Here, we report a case of a giant RCA to LV fistula detected by echocardiography and CCTA.
