Non-surgical treatment of congenital left ventricle to coronary sinus fistula and Wolf-Parkinson-White.

Congenital left ventricle to coronary sinus fistula is a rare entity. We report a case of an infant with prenatal finding of left ventricle to right atrial shunt. The anatomy was defined by multi-modality imaging. Baseline electrocardiogram was notable for a Wolff-Parkinson-White pattern. He underwent successful catheter device closure of the left ventricle to coronary sinus fistula. The patient developed supraventricular tachycardia and underwent successful ablation of the accessory pathway.
