Angiographic measurement of coronary blood flow reserve. Does it work?
T he study reported by Hess et all in this issue of Circulation presents a timely opportunity to discuss several issues that are directly relevant to use of angiographic methods for estimating myocardial perfusion. These issues are motivation for use of angiographic methods, limitations of the gold standard used, limitations of the angiographic method, limitations of the conceptual model used a...
متن کاملPlaque rupture as a cause of apparent coronary aneurysm formation following directional coronary atherectomy.
Late coronary aneurysm formation was observed following treatment by directional coronary atherectomy. Intravascular ultrasound disclosed that the mechanism involved was plaque rupture. The cause of coronary aneurysm may be multifactorial after coronary interventions. Intravascular ultrasound imaging is useful for understanding the pathologic mechanism of coronary aneurysm production.
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 کاملIs rotational atherectomy here to stay?
Rotational atherectomy was developed to ablate selectively inelastic atherosclerotic plaque, while deflecting normal arterial wall away from the rotating burr. Intravascular ultrasound (IVUS) studies have confirmed that rotablation differentially removes even hard, calcified plaque without damaging normal arterial wall. Early in clinical experience, the ability to ablate previously undilatable ...
