Anomalous origin of 4 coronary ostia from the right sinus of Valsalva in a patient with hypertrophic cardiomyopathy.

Anomalous origin of 4 separate coronary ostia from a single coronary sinus has rarely been reported. We report what is to our knowledge a previously undescribed variation characterized by the left anterior descending, left ramus, left circumflex, and right coronary arteries originating from separate ostia in the right sinus of Valsalva. In addition, the autopsy disclosed features of hypertrophic cardiomyopathy, rarely associated with congenital coronary anomalies.
