Randomized Controlled Trial Multicenter Study Comparative Study
A polymer-coated, paclitaxel-eluting stent (Eluvia) versus a polymer-free, paclitaxel-coated stent (Zilver PTX) for endovascular femoropopliteal intervention (IMPERIAL): a randomised, non-inferiority trial.
The clinical effect of a drug-eluting stent in the femoropopliteal segment has not been investigated in a randomised trial with a contemporary comparator. The IMPERIAL study sought to compare the safety and efficacy of the polymer-coated, paclitaxel-eluting Eluvia stent with the polymer-free, paclitaxel-coated Zilver PTX stent for treatment of femoropopliteal artery segment lesions. ⋯ Boston Scientific.

Randomized Controlled Trial Multicenter Study
Blinded outcomes and angina assessment of coronary bioresorbable scaffolds: 30-day and 1-year results from the ABSORB IV randomised trial.
Previous studies showed more adverse events with coronary bioresorbable vascular scaffolds (BVS) than with metallic drug-eluting stents (DES), although in one randomised trial angina was reduced with BVS. However, these early studies were unmasked, lesions smaller than intended for the scaffold were frequently enrolled, implantation technique was suboptimal, and patients with myocardial infarction, in whom BVS might be well suited, were excluded. ⋯ Abbott Vascular.
