This report describes the clinical, echocardiographic and angiographic aspects of a five-day old boy with pulmonary atresia and intact ventricular septum. Both the echocardiogram and the aortography did not show any coronary arteries arising from the aorta. Two-dimensional echocardiography was able to identify the coronary arteries originating from the right ventricle and so did the right ventricular angiogram. No retrograde flow into the aorta or pulmonary trunk was identified after opacification of the coronary arteries. As far as we know this is the first case diagnosed by echocardiography, and is a vivid example of the necessity of identifying the coronary arteries in patients with pulmonary atresia and intact ventricular septum.
