Thin-strut drug-eluting stents are more favorable for severe calcified lesions after rotational atherectomy than thick-strut drug-eluting stents.
AIM Percutaneous coronary intervention (PCI) for severe calcified lesions is still challenging, and there are few studies of drug-eluting stent (DES) implantation for severe calcified lesions, especially regarding long-term results and hemodialysis patients. The study purpose was to clarify the factors, including DES strut thickness, that affect the long-term outcome of severe calcified lesion ...
متن کاملThe outcomes of patients with very small coronary artery disease treated with thin strut cobalt chromium bare metal stents: an observational study
BACKGROUND Percutaneous coronary interventions (PCI) in coronary artery disease (CAD) with very small vessel diameters remains controversial and challenging. These lesions are usually more diffuse, calcified and tortuous. The usage of thin strut bare metal stents (BMS) with excellent crossing profiles in a very small caliber coronary lesions has increased the likelihood of procedural success. ...
متن کاملDrug-eluting stents compared with thin-strut bare stents for the reduction of restenosis: a prospective, randomized trial.
AIM Drug-eluting stents have considerably reduced restenosis. Their relative merits have been assessed on the basis of comparisons made with control bare stents with thick struts. However, increased strut thickness negatively affects restenosis. No direct comparisons between drug-eluting stents and bare stents with thin struts have been performed. The aim of this study was to evaluate the relat...
متن کامل[Comparative analysis of intimal hyperplasia after sirolimus-eluting stent and thin-strut bare-metal stent implantation in small coronary arteries].
OBJECTIVE This study aimed at evaluating reduction in intimal hyperplasia volume following angioplasty using sirolimus-eluting stents (Cypher) compared with thin-strut bare-metal stents (Pixel) in patients with small vessels. METHODS Eighty patients with coronary artery disease were prospectively included in two consecutive series, the first using sirolimus-eluting stents (50) and the second ...
متن کاملStrut position, blood flow, and drug deposition: implications for single and overlapping drug-eluting stents.
BACKGROUND The intricacies of stent design, local pharmacology, tissue biology, and rheology preclude an intuitive understanding of drug distribution and deposition from drug-eluting stents (DES). METHODS AND RESULTS A coupled computational fluid dynamics and mass transfer model was applied to predict drug deposition for single and overlapping DES. Drug deposition appeared not only beneath re...
