AIMS: To investigate whether long-term (3-year) clinical outcomes after multivessel treatment with the Resolute zotarolimus-eluting stent (R-ZES) were similar to single-vessel treatment. METHODS AND RESULTS: The RESOLUTE Global Clinical Trial Program enrolled 7618 patients, of whom 1562 underwent multivessel and 6053 single-vessel treatment with the R- ZES. Patients in the multivessel group were more likely to have complex lesions (58% vs 44%, p<0.001). Clinical outcomes were compared using a Cox regression model adjusted by propensity score to account for differences in baseline characteristics...

The advent of intracoronary stents greatly increased the safety and applicability of percutaneous coronary interventions. One of the drawbacks of drug eluting stents (DES) is the increased risk of late and very late stent thrombosis (ST). The risk of ST after the DES implantation were anticipated to be solved with the advent of fully biodegradable scaffolds which offers the possibility of transient scaffolding of the vessel to prevent acute vessel closure and recoil while also transiently eluting an antiproliferative drug to counteract the constrictive remodeling and excessive neointimal hyperplasia...

AIMS: Selective use of DES only in patients at higher risk of MACE is common practice, particularly in health care systems with a large premium payable for DES. We aimed to identify subgroups of patients in which the use of BMS in primary percutaneous coronary intervention (PPCI) for STEMI can still be justified. METHODS AND RESULTS: We performed a patient-level pooled analysis of COMFORTABLE-AMI and EXAMINATION comparing contemporary DES with BMS in PPCI. A risk score was applied using three parameters: lesion length>15mm, vessel size <3mm, and diabetes mellitus...

AIMS: The aim was to determine the best functional position of a transcatheter heart valve (THV) implanted as a valve-in-valve (ViV) procedure in small rapid deployment valves (RDV) in an in vitro model. METHODS AND RESULTS: A 21mm Perceval™, Enable™ or INTUITY™ RDV was mounted into a pulse duplicator and a 23mm balloon-expandable or a self-expanding THV was deployed (valve-in-valve) in two different positions. Under physiological hydrodynamic conditions, performance of the THV was characterized by mean transvalvular pressure gradient (MPG), effective orifice area (EOA) and regurgitation volume (RV)...

AIMS: It has become clearly apparent that in comparison to metallic stents, bioresorbable vascular scaffold (BVS) require specific implantation techniques. The aim of this study was to investigate outcomes following BVS implantation using a dedicated strategy for optimal deployment. METHODS AND RESULTS: 400 consecutive lesions (264 patients) treated with Absorb BVS were analyzed. All procedures were performed based on the following principles: 1) aggressive lesion preparation; 2) high-pressure post-dilation; and 3) a low threshold for intravascular imaging...

AIMS: During transradial coronary catheterization the radial artery is functionally occluded and hand perfusion depends on the collateral circulation. Nexfin is a simple, non-invasive technique to measure digital arterial pressure and could serve to quantify the palmar collateral circulation. Potentially, inter-individual differences in the extent of collateralization are related to perfusion and function after transradial intervention. METHODS AND RESULTS: In total 85 adults were included (18 healthy volunteers; 67 patients who underwent transradial catheterization)...

AIMS: We sought to evaluate the impact of permanent pacemaker (PPM) implantation on two-year mortality and one-year left ventricular ejection fraction recovery (∆LVEFR=one-year LVEF-baseline LVEF) after transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: We pooled patient-level data from four European institutions with significant TAVI volume. Outcomes were compared between patients without PPM (no-PPM), patients with PPM prior to TAVI (old-PPM) and patients with PPM implanted after TAVI (new-PPM)...

AIMS: Mitral annular calcification (MAC) negatively influences outcomes in surgical mitral valve (MV) repair for mitral regurgitation (MR). However, there are no data on whether MAC impacts on outcomes of MitraClip percutaneous MV edge-to-edge repair. This study sought to investigate whether the presence of MAC impacts on the procedural success and durability of percutaneous transcatheter repair of MR using the MitraClip. METHODS AND RESULTS: One hundred and seventy-three patients undergoing MitraClip repair for significant MR were studied...

AIMS: The aim of this study was to evaluate the biological efficacy of a novel lower-dose (2.5 µg/mm2) encapsulated paclitaxel nanocrystal-coated balloon (Nano-PCB) in the familial hypercholesterolaemic swine (FHS) model of iliofemoral in-stent restenosis. METHODS AND RESULTS: Nano-PCB pharmacokinetics were assessed in 20 femoral arteries (domestic swine). Biological efficacy was evaluated in ten FHS: 14 days following bare metal stent implantation each stent segment was randomised to a clinically available PCB (IN...

AIMS: In the HORIZONS-AMI trial, bivalirudin compared to unfractionated heparin (UFH) plus a glycoprotein IIb/IIIa inhibitor (GPI) improved net clinical outcomes in patients undergoing primary percutaneous coronary intervention (PCI) at the cost of an increased rate of acute stent thrombosis. We sought to examine whether these effects are dependent on time to treatment. METHODS AND RESULTS: The interaction between anticoagulation regimen and symptom onset to first balloon inflation time (SBT) on the 30-day and three-year rates of major adverse cardiac events (MACE) was examined in 3,199 randomised patients according to SBT ≤3 hours versus >3 hours...

AIMS: Randomised controlled trials (RCTs) represent the most robust source of evidence-based medicine. However, the generalisability of RCTs is limited by the inclusion of selected populations. We sought to assess the external validity of a contemporary trial including patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). METHODS AND RESULTS: Patients presenting to Bern University Hospital during the inclusion period of the COMFORTABLE AMI trial were divided into three groups: RCT participants (41%), eligible not included (17...

AIMS: Recently, favourable procedural 30-day and one-year outcomes with the Diamondback 360 Orbital Atherectomy System (OAS) in the treatment of severely calcified lesions have been reported. The purpose of this study was to assess the therapeutic mechanism and efficacy of the OAS with optical coherence tomography (OCT) imaging. METHODS AND RESULTS: This was an observational imaging study in 18 patients with complex calcified coro-nary artery lesions who underwent percutaneous coronary intervention with the OAS...

AIMS: The aim of the study was to investigate the 20-year trends in rates, patient selection and prognosis of coronary revascularisations in Finland. METHODS AND RESULTS: We identified patients from nationwide registers who had undergone first-ever percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) between 1994 and 2013. We examined changes in procedure rates, patient characteristics and estimated hazard ratios (HR) and 95% confidence intervals for cardiovascular events during this period...
