Background: The advent of bioresorbable vascular scaffolds (BVS) was considered as a potential improvement in percutaneous coronary intervention (PCI) after the groundbreaking development of drug eluting stents (DES). However, the clinical performance, long-term safety and efficacy of BVS in complex coronary lesions remain uncertain. COMPARE ABSORB, a multicenter, single blind, prospective ...

Objectives: We sought to determine the efficacy and safety of a scoring balloon for the treatment of in-stent restenosis (ISR). Background: The optimal therapy for ISR is not yet properly established and subject to many discussions. The GRIP™ Balloon (Acrostak, Switzerland) might be of interest for the treatment of certain types of ISR. Methods: Between 2003 and 2009, 157 patients who were...

Background Recent reports suggest an elevated incidence of bioresorbable vascular scaffold (BVS) thrombosis (scaffold thrombosis [ScT]).Objectives This study investigated occurrence rates, clinical and angiographic characteristics, and possible mechanisms of ScT in all-comer patients undergoing BVS implantation at 2 German and 2 Swiss hospitals.Methods A total of 1,305 consecutive patients...

Background: Several parameters of cardiovascular physiology and pathophysiology exhibit circadian rhythms. Recently, a relation between infarct size and the time of day at which it occurs has been suggested in experimental models of myocardial infarction. The aim of this study is to investigate whether circadian rhythms could cause differences in ischemic burden in patients with ST-elevation...

ObjectivesThe authors aimed to compare long-term data of an ultrathin cobalt- chromium stent with passive silicon carbide coating and an active biodegradable polymer that releases sirolimus (O-SES) (Orsiro, BIOTRONIK, Bülach, Switzerland) with the durable polymer-based Xience Prime everolimus-eluting stent (X-EES) (Abbott Vascular, Santa Clara, California).BackgroundBiodegradable polymer...

Background—Biodegradable polymers for release of antiproliferative drugs from drug-eluting stents aim to improve vascular healing. We assessed noninferiority of a novel ultrathin strut drug-eluting stent releasing sirolimus from a biodegradable polymer (Orsiro, O-SES) compared with the durable polymer Xience Prime everolimus-eluting stent (X-EES) in terms of the primary end...

Background: Second-generation everolimus-eluting stents (EES) and third generation biolimus-eluting stents (BES) have been shown to be superior to first-generation paclitaxel-eluting stents (PES) and second-generation sirolimus-eluting stents (SES). However, neointimal proliferation and very late stent thrombosis is still an unresolved issue of drug-eluting stent (DES) implantation overall. The...

Objectives: This study sought to compare the efficacy of passive stent coating with titanium-nitride-oxide (TiNO) with drug-eluting stents releasing zotarolimus (ZES) (Endeavor, Medtronic, Minneapolis, Minnesota).Background: Stent coating with TiNO has been shown to reduce restenosis compared with bare-metal stents in experimental and clinical studies.Methods: In an assessor-blind noninferiority...

Contrast-induced nephropathy (CIN) is an acute renal injury due to the renal toxicity of iodinated contrast media. It is classically defined as a relative (≥25%) or absolute (≥0.5 mg/dl; 44 μmol/l) increase in serum creatinine from baseline value. CIN accounts for 10 to 15% of hospital-acquired acute renal failure and may rarely lead to irreversible renal function loss. Following...

Background Peri-stent coronary evaginations may disturb flow and have been proposed as possible risk factor for late stent thrombosis. We describe incidence, predictors, and possible mechanisms of coronary evaginations 12 months after implantation of bioresorbable vascular scaffolds (BVS).Methods and results One hundred and two BVS implanted in 90 patients...
