  • Abstract
  • Look Inside

Anomalus coronary artery originating from the aorta without complicated congenital cardiac ano-mary is rare. We describe a case with the left coronary artery originating from the right sinus of Valsalva. Cardiac catheterization revealed a left coronary artery transverse between the aorta and the pulmonary artery. Severe atherosclerotic stenosis was present at segment 3 of the right coronary artery. Electrocardiogram and myocardial scinti-graphy revealed that the angina occurred due to stenosis of the right coronary artery.

We tried PTCA, but could not pass the catheter through the stenosis After PTCA, he complained of anterior chest pain frequently, so we performed an aortocoronary bypass operation to the right coronary artery with saphenous vein graft. Post-oparative course was not eventful and angina disap-peared.
