Asymptomatic spontaneous coronary artery dissection.

Spontaneous coronary artery dissection (SCAD) is a rare cause of myocardial ischemia that could present as angina, acute myocardial infarction, or even sudden death. It occurs more commonly in women and it has been associated with autoimmune and collagen vascular diseases. The management and prognosis in these patients depend on the initial clinical presentation and the extent of dissection. In this article, we report 2 cases of asymptomatic SCAD that were diagnosed on routine preoperative evaluation. The management options and clinical implications are discussed.
