Comparison of histopathologic coronary lesions obtained from directional atherectomy in stable angina versus acute coronary syndromes.
T he transition of coronary lesions from the stable to unstable state is the pathophysiologic mechanism underlying myocardial infarction and unstable angina pectoris. Angiographic, angioscopic and postmortem pathologic studies suggest that this transition is mainly due to atherosclerotic plaque fissuring and associated thrombus formation.‘.2 The present study examines the tiistopathologic chara...
متن کاملComparison of directional coronary atherectomy-based intervention and stenting alone in ostial lesions of the left anterior descending artery.
BACKGROUND Balloon angioplasty yields suboptimal results and increases the rate of restenosis in the ostium of the left anterior descending coronary artery (LAD). Several non-balloon devices have been used to improve the outcome of dilatation of such lesions. METHODS This investigation retrospectively compared the results of a directional atherectomy (DCA)-based intervention and stenting alon...
متن کامل‘Optimal’ Directional Coronary Atherectomy
Background—Previous clinical trials of directional coronary atherectomy (DCA) have failed to show significant improvement in early or late outcomes compared with balloon angioplasty (PTCA). The present study tested the hypothesis that more aggressive “optimal” atherectomy could be performed safely to produce larger initial lumen diameters and a lower late restenosis rate. Methods and Results—Th...
متن کاملDirectional Coronary Atherectomy
Background. Directional coronary atherectomy has recently become available to treat coronary stenoses. This study was performed to determine the relation of patient characteristics and stenosis morphology to procedural outcome with directional coronary atherectomy to gain insight into which patients might be best treated with this device. Methods and Results. Four hundred stenoses from 378 pati...
