Acute left main coronary artery occlusion--a case report and review of the literature.
Acute left main coronary artery (LMCA) occlusion is rare and typically fatal. According to the recent literature, only three cases have been reported surviving emergent coronary artery bypass grafting (CABG) for acute myocardial infarction (AMI) caused by total LMCA occlusion. We report the case of a 52-year-old man presenting with total occlusion of the LMCA associated with acute anterolateral myocardial infarction and cardiogenic shock. The patient's dominant right coronary artery did not supply the collaterals to the left coronary system. After ineffective thrombolysis the patient underwent successful emergent CABG for the management of uncontrollable cardiogenic shock. Emergent CABG, though controversial, appears to be a feasible approach for patients with AMI in life-threatening situations, when other attempts at reperfusion have been unsuccessful.
