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...
متن کاملRotational atherectomy: Technical update.
Percutaneous coronary intervention is currently the most common form of revascularization for symptomatic coronary artery disease. In elderly, diabetic and renal patients, there is an increased prevalence of calcified coronary disease. Rotational atherectomy (RA) can be useful in the treatment of these lesions. Plaque removal was initially proposed as an alternative to balloon angioplasty, henc...
متن کاملCurrent status of rotational atherectomy.
Despite the increasing use of percutaneous transluminal coronary angioplasty and intracoronary stent placement for the treatment of obstructive coronary artery disease, a large subset of coronary lesions cannot be adequately treated with balloon angioplasty and/or intracoronary stenting alone. Such lesions are often heavily calcified or fibrotic and undilatable with the present balloon technolo...
متن کاملRotational 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...
متن کاملAggressive plaque modification with rotational atherectomy and cutting balloon for optimal stent expansion in calcified lesions
OBJECTIVE To evaluate the factors affecting optimal stent expansion in calcified lesions treated by aggressive plaque modification with rotational atherectomy (RA) and a cutting balloon (CB). METHODS From January 2014 to May 2015, 92 patients with moderate to severe coronary calcified lesions underwent rotational atherectomy and intravascular ultrasound imaging at Chinese PLA General Hospital...
