Recurrent Spontaneous Coronary Artery Dissection in 4 Vascular Territories.

Spontaneous coronary artery dissection, a rare cause of acute coronary syndrome, is due to nonatherosclerotic coronary events and is probably underrecognized as a cause of myocardial infarction. The condition typically affects premenopausal women who are otherwise healthy. Among more than 1,200 reported cases, recurrent dissection has been described 63 times, and only 3 reports have documented multiple episodes of dissection involving different vascular territories. We present the case of a woman in her 30s who, over a 9-year period, presented 4 times with coronary dissection in different vascular territories. She was first treated conservatively, then with stents, and ultimately by means of coronary artery bypass grafting. In addition to this case, we discuss this rare condition and its management.
