Meta Analysis Comparative Study
Temporal Trends in Adverse Events After Everolimus-Eluting Bioresorbable Vascular Scaffold Versus Everolimus-Eluting Metallic Stent Implantation: A Meta-Analysis of Randomized Controlled Trials.
Bioresorbable coronary stents have been introduced into clinical practice to improve the outcomes of patients treated with percutaneous coronary intervention. The everolimus-eluting bioresorbable vascular scaffold (BVS) is the most studied of these stent platforms; however, recent trials comparing BVS with everolimus-eluting metallic stents (EES) raised concerns about BVS safety. We aimed to assess the efficacy and safety of BVS versus EES in patients undergoing percutaneous coronary intervention. ⋯ Our meta-analysis of randomized trials with a follow-up of ≥2 years demonstrated a higher risk of ST and of TLF in patients treated with BVS compared with EES. Of note, BVS had a higher risk of subacute, late, and very late ST, whereas the risk of TLF and TLR was higher between 1 and 2 years.

Randomized Controlled Trial Multicenter Study Comparative Study
Hemocompatibility-Related Outcomes in the MOMENTUM 3 Trial at 6 Months: A Randomized Controlled Study of a Fully Magnetically Levitated Pump in Advanced Heart Failure.
The HeartMate 3 (HM3) Left Ventricular Assist System (LVAS) (Abbott) is a centrifugal, fully magnetically levitated, continuous-flow blood pump engineered to enhance hemocompatibility and reduce shear stress on blood components. The MOMENTUM 3 trial (Multicenter Study of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy With HeartMate 3) compares the HM3 LVAS with the HeartMate II (HMII) LVAS (Abbott) in advanced heart failure refractory to medical management, irrespective of therapeutic intention (bridge to transplant versus destination therapy). This investigation reported its primary outcome in the short-term cohort (n=294; 6-month follow-up), demonstrating superiority of the HM3 for the trial primary end point (survival free of a disabling stroke or reoperation to replace the pump for malfunction), driven by a reduced need for reoperations. The aim of this analysis was to evaluate the aggregate of hemocompatibility-related clinical adverse events (HRAEs) between the 2 LVAS. ⋯ URL: http://clinicaltrials.gov.

Calcification of the aortic valve leads to increased leaflet stiffness and consequently to the development of calcific aortic valve disease. However, the underlying molecular and cellular mechanisms of calcification remain unclear. Here, we identified that dipeptidyl peptidase-4 (DPP-4, also known as CD26) increases valvular calcification and promotes calcific aortic valve disease progression. ⋯ DPP-4-dependent insulin-like growth factor-1 inhibition in VICs contributes to aortic valve calcification, suggesting that DPP-4 could serve as a potential therapeutic target to inhibit calcific aortic valve disease progression.
