[Two cases of coronary artery-left ventricular fistula associated with left ventricular hypertrophy].

Two cases of coronary artery-left ventricular fistula (AVF) associated with left ventricular hypertrophy were reported. The first patient was a 53-year-old man with chest pain. Selective coronary angiography (CAG) revealed bilateral coronary arteries draining into the left ventricle (LV). The second patient was a 46-year old man with electrocardiographic (ECG) abnormalities. CAG showed bilateral coronary artery which communicated via a maze of fine vessels into LV. In both cases, ECG showed ST depression and inverted T wave, and two-dimensional echocardiography revealed hypertrophic cardiomyopathy (HCM). Coexistence of coronary artery-left ventricular fistula and HCM seems to be a casual association.
