Spontaneous coronary artery dissection is a rare but often fatal cause of acute myocardial ischemia that occurs in young or middle-aged and otherwise healthy patients. We report a case of spontaneous left main coronary artery dissection in a young woman who was treated with emergency coronary artery bypass grafting. She improved after surgery but required a long recuperative period because of her cardiac failure and multiple organ failure, developed expiring on the 78th postoperative day. Spontaneous coronary artery dissection is unpredictable, and sudden death is the usual mode of clinical presentation. Prompt diagnosis and coronary artery revascularization are essential in order to achieve a favorable outcome in such cases.
