Echocardiographic findings in right coronary arterial-right ventricular fistula. Report of a neonate with fatal congestive heart failure.
Coronary arteriovenous fistula is a rare cause of congestive heart failure in the newborn. We describe a 2 day old infant with a large fistula between the right coronary artery and right ventricle that caused fatal congestive heart failure. An echocardiographic study revealed a large right ventricle, paradoxical motion of the interventicular septum and an enlarged aorta, suggesting an unusual location of a left to right shunt. The diagnosis was established at cardiac catheterization when a large left to right shunt was found at the ventricular level; the fistula was visualized by angiography.
