Spontaneous Multivessel Coronary Artery Dissection in a Young Asymptomatic Patient

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 2 2004
ALEKSANDR ROVNER M.D.
A unique case of spontaneous multivessel coronary artery dissection in a young woman without identifiable risk factors, who remained asymptomatic despite extensive coronary dissection is presented. The management of this condition and a review of the current literature on this subject are presented. (J Interven Cardiol 2004;17:123,127) [source]

Clinical and Angiographic Outcome after Cutting Balloon Angioplasty

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 1 2003
JOHANN AUER M.D.
The cutting balloon is a new device for coronary angioplasty, that, by the combination of incision and dilatation of the plaque, is believed to be promising for treatment of in-stent restenosis. The purpose of the study was to evaluate the safety and efficacy of CBA. We reviewed the immediate and 6-month follow-up angiographic and clinical outcome of 147 patients (109 men and 38 women) with a mean age of67.3 ± 10undergoing this procedure at eight interventional centers in Austria. The target lesions treated with CBA were in-stent restenosis in 61% of patients, stenosis after balloon angioplasty in 8% of patients, and native lesions in 33% of patients. Sixty-five percent of the patients included had multivessel disease. Lesion type was A in 18% of patients, B1 in 31% of patients, B2 in 39% of patients, and C in 12% of patients. The degree of stenosis was87%± 9%,the length of the target lesion treated with CBA was8.8 ± 5.1 mm. Target vessel was left circumflex artery in 22 cases, right coronary artery in 36 cases, and left anterior descending artery in 89 cases. The overall procedural success rate was 90.5%. "Stand-alone" CBA was performed in 63% of patients, the procedure was combined with coronary stenting in 16% of patients, and with balloon angioplasty in 21% of patients. Coronary complications occurred in eight cases (5.4%) with coronary dissection in seven (total dissection rate of 4.7%) and urgent bypass surgery in one case (0.7%). No further complications such as death, occlusion, or perforation of coronary arteries, embolization, or thrombosis were observed. Six-month clinical follow-up revealed q-wave myocardial infarction in 2.7% of patients, aortocoronary bypass surgery in 8.5% of patients, and repeated percutaneous coronary intervention in 17% of patients (11.5% with stenting). Six-month angiographic follow-up of patients with recurrent angina showed target lesion restenosis (>50% diameter stenosis) in 14% of patients, late lumen loss with ,50% diameter stenosis in 6% of patients and progression of "other than target" lesions with >50% diameter stenosis in 14% of patients. This series demonstrates the safety and feasibility of cutting balloon angioplasty in patients with complex coronary artery disease and in-stent restenosis.

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]

Two Brothers with Myocardial Infarction in the Absence of Atherosclerotic Coronary Artery Disease: Spontaneous Coronary Thrombosis: Case Reports of Two Brothers

CLINICAL CARDIOLOGY, Issue 12 2009
Jamal Hussain MD
Myocardial infarction in the absence of significant atherosclerotic coronary artery disease is not uncommonly encountered in clinical practice. This has been more often seen with the current sensitive biomarker assays for myocardial necrosis. Acute illnesses, spontaneous coronary dissection, sepsis, pulmonary embolism and coagulation disorders are some of the common clinical situation where elevated cardiac markers are noted. We describe two brothers presenting with acute myocardial infarction due to thrombus without any obvious cause. Copyright © 2009 Wiley Periodicals, Inc. [source]
