Atherosclerosis in Type IV Dual Left Anterior Descending Artery and Anomalous Aortic Origin of the Left Circumflex Artery in Association with Rheumatic Valve Disease: A Case Report
AbstractDouble left anterior descending coronary artery arising from the left and right coronary arteries is a very rare congenital coronary artery anomaly. In this case, there was also a circumflex artery arising from the right sinus Valsalva and in association with severe rheumatic valve disease. Subsequently, the patient underwent mechanical aortic valve replacement with a 21-mm bileaflet mechanical aortic valve and coronary artery bypass grafting. We performed coronary artery bypass grafting of 3 vessels, including the left internal mammary artery to the large diagonal branch and the saphenous vein graft to the circumflex artery and the right coronary artery, under cardiopulmonary bypass. In this report, we describe an unusual case of this combination in association with both atherosclerosis and rheumatic aortic and mitral valve disease.
