Spontaneous dissection of the distal obtuse marginal coronary artery: a rare cause of sudden death.
Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction and sudden death. It typically, but not always, occurs in healthy postpartum women without traditional risk factors for atherosclerosis. Moreover, the site of dissection usually involves the proximal, major coronary arteries: left main coronary artery and/or the left anterior descending artery, and in men, more often the right coronary artery. We report a case of sudden death caused by dissection of the obtuse marginal branch of the left circumflex artery, in a 49-year-old man, a very rare site of fatal coronary dissection.
