متن کاملRecurrent unstable angina after directional coronary atherectomy is related to the extent of initial coronary plaque inflammation.
OBJECTIVES This study was performed to evaluate the relationship between plaque inflammation of the initial culprit lesion and the incidence of recurrent angina for one year after directional coronary atherectomy (DCA). BACKGROUND A positive correlation between coronary plaque inflammation and angiographic restenosis has been reported. METHODS A total of 110 patients underwent DCA. Cryostat...
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...
متن کاملComparison 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...
