One-Year Outcomes in "Real-World" Patients Treated With a Thin-Strut, Platinum-Chromium, Everolimus-Eluting Stent (from the PROMUS Element Plus US Post-Approval Study [PE-Plus PAS]).

The PROMUS Element Plus US Post-Approval Study (PE-Plus PAS) was a prospective, open-label, multicenter, observational study designed to examine outcomes in everyday clinical practice in patients treated with everolimus-eluting, platinum-chromium PROMUS Element Plus stents at 52 centers in the United States. This is the first report of results from this large study. The primary end point of the PE-Plus PAS was 12-month cardiac death or myocardial infarction in the more restricted population of "PLATINUM-like" patients pooled from the PE-Plus PAS, PE-PROVE (PROMUS Element European post-approval study), and PLATINUM Workhorse/Small Vessel trials.

Cost-effectiveness of percutaneous coronary intervention versus bypass surgery from a Dutch perspective.

Aims: Recent cost-effectiveness analyses of percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) have been limited by a short time horizon or were restricted to the US healthcare perspective. We, therefore, used individual patient-level data from the SYNTAX trial to evaluate the cost-effectiveness of PCI versus CABG from a European (Dutch) perspective.

Methods And Results: Between 2005 and 2007, 1800 patients with three-vessel or left main coronary artery disease were randomised to either CABG (n=897) or PCI with drug-eluting stents (DES; n=903).

The impact of a second arterial graft on 5-year outcomes after coronary artery bypass grafting in the Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery Trial and Registry.

Objective: Despite various evidence supporting the advantages of multiple arterial grafting, inconsistencies in use of the procedure have resulted in high variability in the acceptance and practice of arterial grafting. The purpose of this study was to assess the effects of an arterial versus venous second grafts on outcomes at 5-year follow-up in the coronary artery bypass grafting population from the Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) trial.

Methods: Patients (n = 1419) with an arterial graft to the left anterior descending artery and ≥1 other graft were included and divided according to the second graft's type: 2nd-graft-arterial group (n = 456) and 2nd-graft-venous group (n = 963).

Efficacy and safety of a novel bioabsorbable polymer-coated, everolimus-eluting coronary stent: the EVOLVE II Randomized Trial.

Background: Drug eluting stents with durable polymers may be associated with hypersensitivity, delayed healing, and incomplete endothelialization, which may contribute to late/very late stent thrombosis and the need for prolonged dual antiplatelet therapy. Bioabsorbable polymers may facilitate stent healing, thus enhancing clinical safety. The SYNERGY stent is a thin-strut, platinum chromium metal alloy platform with an ultrathin bioabsorbable Poly(D,L-lactide-co-glycolide) abluminal everolimus-eluting polymer.
