Spontaneous coronary artery dissection

CLINICAL CARDIOLOGY, Issue 7 2004
Francis Q. Almeda M.D.
Abstract Spontaneous coronary artery dissection (SCAD) is an unusual cause of acute myocardial ischemia with complex pathophysiology. This paper reviews the major diagnostic and therapeutic issues of this rare but important disease. The diagnosis of SCAD should be strongly considered in any patient who presents with symptoms suggestive of acute myocardial ischemia, particularly in young subjects without traditional risk factors for coronary artery disease (especially in young women during the peripartum period or in association with oral contraceptive use). Urgent coronary angiography is indicated to establish the diagnosis and to determine the appropriate therapeutic approach. The decision to pursue medical management, percutaneous coronary intervention, or surgical revascularization is based primarily on the clinical presentation, extent of dissection, and amount of ischemic myocardium at risk.

Dor Operation for a Young Male with Left Ventricular Aneurysm due to Spontaneous Left Anterior Descending Coronary Artery Dissection

JOURNAL OF CARDIAC SURGERY, Issue 1 2004
Masato Nakajima M.D.
We describe a young male who had a myocardial infarction with left ventricular aneurysm due to spontaneous left anterior descending coronary artery dissection. He was successfully treated with Dor's left ventriculoplasty without coronary artery revascularization. The Dor procedure was a simple and effective treatment. To our knowledge, this is the first report in which the Dor procedure was used to treat spontaneous coronary artery dissection with left ventricular aneurysm. (J Card Surg 2004;19:54-56) [source]

Natural History of a Giant Coronary Aneurysm With Spontaneous Dissection

CLINICAL CARDIOLOGY, Issue 12 2009
Alberto Bouzas-Mosquera MD
Primary spontaneous coronary artery dissection may appear in young women during the peripartum period or as a result of atherosclerosis. We present a patient with familial hypercholesterolemia who developed a giant aneurysm of the right coronary artery in the setting of atherosclerotic spontaneous coronary dissection over an 8 year period. This report illustrates the association between spontaneous coronary artery dissection and subsequent coronary aneurysm formation. Copyright © 2009 Wiley Periodicals, Inc. [source]

Postpartum dissection of the left main coronary artery

CLINICAL CARDIOLOGY, Issue 4 2006
Ian S. Rogers M.D., M.B.A.
Abstract Peripartum coronary artery dissection is rare, but it is an increasingly recognized risk to women of childbearing age. Literature reviews reveal that about 80% of the population with spontaneous coronary artery dissections (SCAD) are female, and approximately 25,33% of cases occurred while the woman was pregnant or in the peripartum phase. Most cases have presented within 2 weeks of delivery. The left anterior descending is the most commonly affected vessel. The etiology is poorly understood, but many reports suggest that SCAD occurs as a result of protease release secondary to an eosinophilic vasculitis resulting in vessel lysis. Many investigators have examined the correlation between peripartum SCAD and estrogen levels; however, case studies have shown conflicting results regarding estrogen levels as the putative causative factor. Optimal treatment remains controversial. Presently, stenting appears to be best employed in the patients who have single-vessel dissection not involving the left main coronary artery (LMCA). Surgical revascularization via coronary artery bypass graft remains the optimal therapy in patients whose dissection involves the LMCA, in patients with concurrent multi-vessel dissection, and in patients with disease refractory to medical management. It is important to consider coronary artery dissection in the differential of any young woman who presents with signs or symptoms consistent with acute coronary syndrome, particularly if she is peripartum. Furthermore, once suspected, it is imperative that a definitive diagnostic study, that is, coronary angiography, be completed prior to the initiation of treatment whenever possible. [source]
