title: Successful treatment of a nonagenarian patient with acute coronary syndrome complicated with chronic total occlusion of the left main coronary artery.
abstract: Although chronic total occlusion of the left main coronary artery (LMCA) is considered very rare, this condition could be fatal if it becomes complicated with an acute coronary syndrome lesion in the right coronary artery (RCA) which is usually the only remaining coronary artery for the myocardium. We reported a successfully treated case of a nonagenarian patient with ST-segment elevation myocardial infarction, who had subtotal occlusion of the RCA and total occlusion of the LMCA with Rentrop grade 2 collateral coronary artery supply from the RCA.
