Ostial left main coronary artery chronic total occlusion presenting as chronic stable angina
Significant left main coronary artery (LMCA) disease is found in 5–6% of all patients undergoing coronary angiography. It usually presents as acute coronary syndrome and is commonly associated with multi-vessel coronary artery disease (CAD). Complete occlusion of LMCA is a much rarer finding, since...

description | Significant left main coronary artery (LMCA) disease is found in 5–6% of all patients undergoing coronary angiography. It usually presents as acute coronary syndrome and is commonly associated with multi-vessel coronary artery disease (CAD). Complete occlusion of LMCA is a much rarer finding, since these patients usually present as unstable angina, myocardial infarction and cardiogenic shock. We report a case of a young female, who presented with chronic stable angina and had an isolated chronic total occlusion (CTO) of LMCA with no lesions in the other coronary arteries. Aortogram failed to demonstrate the stump of occluded LMCA and demonstrated the filling of the left coronary system from the right coronary artery. Apart from dyslipidemia, she had no other risk factors for CAD. She was extensively evaluated for non-atherosclerotic causes of LMCA CTO including vasculitis. She underwent coronary artery bypass graft successfully without any peri-procedural complications. |
