Single coronary artery from the right sinus of Valsalva, associated with absence of left anterior descending and an ostium-secundum-type atrial septal defect: a rare combination. A case report.

A case of single coronary artery from the sinus of Valsalva, with an anomalous origin of the left circumflex coronary artery from the just proximal portion of the right coronary artery, absence of the left anterior descending, and an ostium-secundum-type atrial septal defect is presented. This combination seems to be very rare.
