Use, Safety and Effectiveness of Subintimal Angioplasty and Re-Entry Devices for the Treatment of Femoropopliteal Chronic Total Occlusions: A Systematic Review of 87 Studies and 4,665 Patients.

Background: Subintimal angioplasty (SIA) is often utilized to cross femoropopliteal (FP) artery chronic total occlusions (CTOs). Re-entry devices (RED) can further assist with true lumen re-entry.

Objective: To systematically review the literature for studies reporting on the use of SIA, with or without RED.

Second-generation drug-eluting stents versus drug-coated balloons for the treatment of coronary in-stent restenosis: A systematic review and meta-analysis.

Purpose: The benefit of drug-eluting stents (DES) versus drug-coated balloons (DCB) in coronary artery in-stent restenosis (ISR) for the prevention of target lesion revascularization (TLR), stent thrombosis, and mortality remains uncertain. Our aim was to synthesize the available evidence from randomized clinical trials (RCTs) and observational studies that directly compare second-generation drug-eluting stents (SG-DES) and DCB for the treatment of coronary ISR.

Methods: Medline, Embase, and Cochrane Central were searched for RCTs or observational studies, published up to March 15, 2017.
