Single chamber pacemaker implantation leads to a desynchronization of ventricular depolarization. This study aims to evaluate the implant of biventricular versus univentricular pacemaker. 902 patients were included in the group with biventricular pacemaker and 908 in the univentricular pacing group. The primary objective was to evaluate the long-term mortality and needs hospitalization for heart failure....

This multicenter noninferiority design work included 1399 patients randomized to receive 6 months (n = 682) versus 1 year (n = 717) dual anti-aggregation after implantation of 2nd generation drug-eluting stent. The primary end point was a composite of cardiac death, myocardial infarction, stroke, definite or probable thrombosis, and major bleeding. At 12 months follow-up...
While the use of intravascular ultrasound (IVUS) during coronary intervention proved useful in multiple studies, there is limited evidence in the literature regarding its use in specifically in chronic total occlusions. The IVUS may help guide in recognizing the true lumen and better distal positioning, better coverage of stent, an optimal apposition and expansion, diagnose...
This paper included 5 studies that randomized patients to conventional stent versus chromium cobalt everolimus eluting stent; at 2 years, a significantly lower risk of cardiac death (2.7% for the everolimus eluting stent versus 4% for conventional stent, p = 0013) was observed. Myocardial infarction was reduced by over 80% with drug-eluting stent (0.08% versus...
The aim of this study was to evaluate the performance of the sirolimus eluting stent with bio -absorbable polymer (MiStent SES) compared with zotarolimus eluting stent with permanent polymer (Endeavor). This 2:1 randomized, multicenter study included 183 patients with the primary objective of evaluating the late lumen loss between the MiStent and Endeavor a two...
This study was designed to compare the apposition and neointimal coverage of struts by optical coherence tomography (OCT) of the new self-expanding sirolimus eluting stent (STENTYS SES) at 4 and 9 months in patients with STE-ACS. 152 patients randomized to STENTYS SES (n = 90) versus zotarolimus-eluting balloon-expandable stent (n = 62) were included. The...
This work aimed to evaluate the use of optical coherence tomography (OCT) to guide the drug-eluting stent implantation during primary angioplasty. 201 patients experiencing STEMI to use or not OCT during primary angioplasty were randomized. The clinical and angiographic characteristics were well balanced, and no differences in MACE, cardiac death, TLR, or stent thrombosis at...

This trial is a prospective evaluation of DESolveTM bioabsorbable coronary stent implantation in a 15 patient cohort enrolled in New Zealand and Belgium. At 6 months follow up, late lumen loss was 0,19 mm, binary restenosis was 0% and thrombosis was absent. OCT evaluation showed excellent stent apposition, and 98% of evaluated struts were covered...
