Repair of anomalous origin of right coronary artery from the left sinus of Valsalva

Anomalous origin of the right coronary artery from the left sinus of Valsalva is a rare congenital anomaly but a relatively frequent cause of sudden death in the young. The medical records of 4 consecutive patients with this anomaly were retrospectively reviewed. The first 2 patients underwent coronary artery bypass and had early graft failure. The next 2 patients underwent coronary reimplantation and unroofing and have done well. This limited series suggests that bypass procedures used to treat anomalous origin of the right coronary artery from the left sinus of Valsalva are prone to early graft failure.
