Directional coronary atherectomy versus coronary angioplasty in vessels larger than 3 mm in diameter.
It has been proposed that directional coronary atherectomy (DCA) should be an intervention of choice in larger vessels as one can achieve a greater minimal luminal diameter with DCA than with percutaneous transluminal coronary angioplasty (PTCA). This in turn should translate into a higher success rate and may even reduce the restenosis rate. The aim of this study was to compare DCA versus PTCA...
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 کاملEfficacy and safety of coronary balloon angioplasty and directional atherectomy.
In this issue of Circulation, Safian et all describe their experience with directional coronary atherectomy. The procedure was successful in removing 88% of lesions, and only one of 67 patients required emergency coronary bypass surgery. However, according to life-table analysis, 30% of the lesions restenosed in the ensuing 6 months. Thus, coronary atherectomy appears to be effective and safe i...
متن کاملComparative quantitative angiographic analysis of directional coronary atherectomy and balloon coronary angioplasty.
An attempt to assess the "utility" of directional atherectomy was made using a new quantitative angiographic index. This index can be subdivided into an initial gain component and a restenosis component. The initial gain index is the ratio between the gain in diameter during intervention and the theoretically achievable gain (i.e., reference diameter). The restenosis index is the ratio between ...
