Impact of PCI Appropriateness in the Long-Term Outcomes of Consecutive Patients Treated With Second-Generation Drug-Eluting Stents.

Background: Appropriate use criteria (AUC) for coronary revascularization were developed to deliver high-quality care; however, the prognostic impact of these criteria remains unclear. We sought to assess the outcomes of patients treated with second-generation drug-eluting stent (DES) classified according to the updated American College of Cardiology Foundation/American Heart Association/Society for Cardiac Angiography and Intervention AUC for percutaneous coronary intervention (PCI).

Methods: Between January 2012 and December 2013, a total of 1108 consecutive patients treated only with second-generation DES were categorized according to the AUC in three groups, using the new proposed terminology: appropriate ("A"); uncertain ("U"); and inappropriate ("I").

EXCELLA First-in-Man (FIM) study: safety and efficacy of novolimus-eluting stent in de novo coronary lesions.

Aims: First generation DES have markedly reduced restenosis. However, there is a major interest in developing new DES with greater flexibility, radiopacity and safety profile. The Elixir Medical drug eluting stent is a novel DES that combines a chromium-cobalt platform with novolimus (an antiproliferative sirolimus-analogue drug) and a polymer from the methacrylate family.

IMPACT Trial: angiographic and intravascular ultrasound observations of the first human experience with mycophenolic acid-eluting polymer stent system.

The purpose of the study was to examine the safety and efficacy of two different formulations of mycophenolic acid (MPA)-eluting Duraflex stents on coronary de novo lesions. Recent data indicate that local delivery of MPA in the porcine overstretch coronary model significantly reduces neointimal hyperplasia (NIH). Patients were divided into three consecutive groups.
