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...
متن کاملRotational 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 کاملRole of Rotational Atherectomy in Percutaneous Coronary Interventions in Elderly
RA is a debulking device that physically removes plaque and reduces plaque rigidity basically altering vessel compliance, similar to that achieved by a dental drill. It works on the principle of “differential cutting”, ablating only the calcified and fibrotic “non-compliant” tissue, while retaining the elastic arterial wall. The hard and calcified plaque is not able to deflect the rota-burr and...
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...
