Rotational Atherectomy Prior to Taxus Stent

2014-08-27 03:42:21 | BioPortfolio

Summary

The primary purpose of this study is to evaluate the long term effects of the polymer-based slow-release paclitaxel-eluting stent (TAXUS; Boston Scientific), with or without prior rotablation, in an angiographically well defined group of patients with complex calcified coronary lesions.

Description

Calcification is an essential part of all atherosclerotic plaques. Its extent increases with the progression of atherosclerotic disease. Heavily calcified lesions form a particular threat to DES; both damage to the polymer coating during vigorous advancement and inadequate diffusion of the drug to the subintima through extensive calcium arcs could contribute to the ineffectiveness of DES when implanted into such lesions, or may lead to primary stent delivery or expansion failure. Rotational atherectomy can effectively ablate calcified plaques. In the DES era, data concerning rotational atherectomy are scarce. DES implantation following rotablation seems a rational combination, but is only poorly supported by controlled studies. In the present study, we are using the polymer-based slow-release paclitaxel-eluting stent (TAXUS; Boston Scientific), with or without prior rotablation, in an angiographically well defined group of patients with complex calcified coronary lesions. This prospective, randomized, controlled study aims at evaluating the long term effects of both strategies in this complex cohort of patients.

Medical and Biotech [MESH] Definitions

Percutaneous transluminal procedure for removing atheromatous plaque from the coronary arteries. Both directional (for removing focal atheromas) and rotational (for removing concentric atheromatous plaque) atherectomy devices have been used.

A family of percutaneous techniques that are used to manage CORONARY OCCLUSION, including standard balloon angioplasty (PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY), the placement of intracoronary STENTS, and atheroablative technologies (e.g., ATHERECTOMY; ENDARTERECTOMY; THROMBECTOMY; PERCUTANEOUS TRANSLUMINAL LASER ANGIOPLASTY). PTCA was the dominant form of PCI, before the widespread use of stenting.

The formation of dentin. Dentin first appears in the layer between the ameloblasts and odontoblasts and becomes calcified immediately. Formation progresses from the tip of the papilla over its slope to form a calcified cap becoming thicker by the apposition of new layers pulpward. A layer of uncalcified dentin intervenes between the calcified tissue and the odontoblast and its processes. (From Jablonski, Dictionary of Dentistry, 1992)

Abnormal balloon- or sac-like dilatation in the wall of CORONARY VESSELS. Most coronary aneurysms are due to CORONARY ATHEROSCLEROSIS, and the rest are due to inflammatory diseases, such as KAWASAKI DISEASE.

Malformations of CORONARY VESSELS, either arteries or veins. Included are anomalous origins of coronary arteries; ARTERIOVENOUS FISTULA; CORONARY ANEURYSM; MYOCARDIAL BRIDGING; and others.
