Single coronary artery-right ventricular fistula.

We report a rare case of a male child aged 4 years and 5 months who was diagnosed with a coronary artery fistula and left single coronary artery. Pre-operative evaluation with echocardiography and selective angiography showed a dilated and tortuous single coronary artery draining into the right ventricular outflow tract. The coronary fistula was ligated. The post-operative and clinical courses were uneventful.
