Local delivery of sirolimus nanoparticles for the treatment of in-stent restenosis.

Objectives: To test the local delivery of sirolimus nanoparticles following percutaneous transluminal coronary angioplasty (PTCA) to treat in-stent restenosis (ISR) in a swine model.

Background: Coronary bare-metal stent (BMS) implantation reduces major adverse cardiac events when compared with PTCA; however, ISR rates remain high.

Methods: Eighteen swine underwent BMS deployment guided by intravascular ultrasound (IVUS).

First-in-man study of simvastatin-eluting stent in de novo coronary lesions: the SIMVASTENT study.

Background: Statins have anti-inflammatory and antiproliferative properties irrespective of their cholesterol-lowering effects. The aim of the present study was to evaluate a simvastatin-eluting stent (SimvES) in the treatment of de novo coronary lesions.

Methods And Results: Forty-two patients with de novo coronary artery lesions were assigned to SimvES, bare-metal stent (BMS) or everolimus-eluting stent (EES) implantation followed by intravascular ultrasound (IVUS) for neointimal quantitative analysis.
