Relation of clinical presentation, stenosis morphology, and operator technique to the procedural results of rotational atherectomy and rotational atherectomy-facilitated angioplasty.

BACKGROUND Rotational atherectomy using the Rotablator has recently become available to treat coronary stenoses. This study was performed to determine the relation of patient characteristics, stenosis morphology, and operator technique to procedural outcome to gain insight into which patients might be best treated with this device. METHODS AND RESULTS Four hundred stenoses from 316 patients r...

Rotational Atherectomy in Clinical Practice

Unlike balloon dilation that results in the displacement of atherosclerotic plaque with multiple intimal tears, rotational atherectomy (RA) is based on the principle of differential cutting that allows for physical removal of inelastic atherosclerotic material while rendering the inner lumen surface smooth. Although plaque reduction by pulverization of atherosclerotic material into <10 μm parti...

Rotational atherectomy: an Update

As we known, drug-eluting stents (DES) reduce the risk of restenosis and represent an important advance in coronary intervention. Newer-generation DES with thin struts releasing limus-family drugs from durable or biodegradable polymers have further improved clinical outcomes, as compared with early-generation DES releasing sirolimus or paclitaxel. The risk of stent thrombosis has become exceedi...

Treatment of calcific coronary stenosis with the use of excimer laser coronary atherectomy and rotational atherectomy

Noncrossable and nondilatable coronary lesions pose a major concern in percutaneous coronary intervention (PCI) often leading to technical failure, incomplete revascularization and complications. With the increasing age of the PCI population and the increasing complexity of cases undertaken in many centers, ‘balloon failure’ is now encountered more frequently. Such calcified stenosis, chronic t...
