BACKGROUND To characterize the cells responsible for neointima formation after porcine coronary artery wall injury, we studied the expression of smooth muscle cell (SMC) differentiation markers in 2 models: (1) self-expanding stent implantation resulting in no or little interruption of internal elastic lamina and (2) percutaneous transluminal coronary(More)
IMPORTANCE Dual antiplatelet therapy after percutaneous coronary intervention (PCI) reduces ischemia but increases bleeding. OBJECTIVE To develop a clinical decision tool to identify patients expected to derive benefit vs harm from continuing thienopyridine beyond 1 year after PCI. DESIGN, SETTING, AND PARTICIPANTS Among 11,648 randomized DAPT Study(More)
BACKGROUND Demonstration and quantification of site-specific intracoronary administration of compounds has been confined thus far to the experimental animal laboratory. The aim of this study was to describe a scintigraphic method to demonstrate site-specific intracoronary drug delivery in humans. The methods allow on-line visualization and off-line(More)
P ercutaneous coronary intervention has become the most frequently used method of myocardial revasculariza-tion. 1,2 The advent of coronary stenting led to a significant decrease in the complications seen after balloon angio-plasty, resulting in improved patient outcome. 3,4 Yet, stented angioplasty has been plagued from the onset by early stent thrombosis(More)
BACKGROUND The safety and efficacy of drug-eluting stents (DES) in the treatment of coronary artery disease have been assessed in several randomised trials. However, none of these trials were powered to assess the safety and efficacy of DES in women because only a small proportion of recruited participants were women. We therefore investigated the safety(More)
OBJECTIVE Heterogeneous smooth muscle cell (SMC) populations have been described in the arteries of several species. We have investigated whether SMC heterogeneity is present in the porcine coronary artery, which is widely used as a model of restenosis. METHODS AND RESULTS By using 2 isolation methods, distinct medial populations were identified:(More)
OBJECTIVE The occurrence of atrial fibrillation after percutaneous closure of a patent foramen ovale for cryptogenic stroke has been reported in a variable percentage of patients. However, its precise incidence and mechanism are presently unclear and remain to be elucidated. DESIGN Prospective follow-up study. PATIENTS Ninety-two patients undergoing a(More)
BACKGROUND Inefficacy of systemic drug administration for restenosis prevention may partially relate to insufficient local drug concentration. This study aimed to evaluate the acute feasibility and long-term outcome of using an infusion-perfusion coil balloon, Dispatch. METHODS AND RESULTS In 22 patients after balloon angioplasty, the coil balloon was(More)
BACKGROUND We sought to compare the long-term safety of two devices with different antiproliferative properties: the Endeavor zotarolimus-eluting stent (E-ZES; Medtronic, Inc) and the Cypher sirolimus-eluting stent (C-SES; Cordis, Johnson & Johnson) in a broad group of patients and lesions. METHODS Between May 21, 2007 and Dec 22, 2008, we recruited 8791(More)
BACKGROUND The use of a stent to deliver a drug may reduce in-stent restenosis. Paclitaxel interrupts the smooth muscle cell cycle by stabilizing microtubules, thereby arresting mitosis. METHODS AND RESULTS On the basis of prior animal studies, the European evaLUation of the pacliTaxel Eluting Stent (ELUTES) pilot clinical trial (n=190) investigated the(More)
