Coronary artery fistula draining into left ventricle: case report and review.

A 6-year-old boy with coronary artery fistula emptying into the left ventricle was reported. An attempt was made to outline clinical manifestations of this disease which have not yet been fully described, based on the experience of the present case and a review of 14 previously reported cases. It is concluded that clinical signs and symptoms are not specific for this anomaly and retrograde aortography is required to establish the definite diagnosis of the lesion. Authors' views are expounded as to the location of maximal intensity of the murmur, genesis of the systolic murmur and electrocardiographic features.
