OBJECTIVE: The aim of this study is to explore major mechanisms of atherosclerotic plaque growth, presenting a proof-of-concept numerical model. METHODS: To this aim, a human reconstructed left circumflex coronary artery is utilized for a multi-level modeling approach. More specifically, the first level consists of the modeling of blood flow and endothelial shear stress (ESS) computation. The second level includes the modeling of low and high density lipoprotein (LDL, HDL) and monocytes transport through the endothelial membrane to vessel wall...

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...

Cigarette smokers with ST-segment elevation myocardial infarction (STEMI) may present different response to potent antithrombotic therapy compared to nonsmokers. We assessed the impact of smoking status and intracoronary abciximab in patients with STEMI undergoing primary percutaneous coronary intervention (PCI). We pooled data from 5 randomized trials comparing intracoronary versus intravenous abciximab bolus in patients undergoing primary PCI. The primary end point was the composite of death or reinfarction at a mean follow-up of 292 ± 138 days...

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: 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...

Patients with advanced chronic renal dysfunction were excluded from randomized trials of transcatheter aortic valve replacement (TAVR). The potential impact of chronic renal disease on TAVR prognosis is not fully understood. We aim to evaluate outcomes within a large cohort of patients who underwent TAVR distinguished by renal function. Baseline characteristics, procedural data, and clinical follow-up findings were collected from 10 high-volume TAVR centers in Europe, Israel, and Japan. Data were analyzed according to renal function...

AIMS: The minimum fibrous cap thickness (FCT) is considered a major criterion of coronary plaque vulnerability according to autopsy studies. We aimed to assess the reproducibility in the measurement of the optical coherence tomography (OCT)-detected minimum FCT and the agreement in the classification of thin-cap fibroatheroma (TCFA), by a software-based semi-automatic method compared with the manual method. METHODS AND RESULTS: A total of 50 frames with fibroatheromas (FA) were randomly selected from the Integrated Biomarker Imaging Study-4 (IBIS-4)...

Surgical techniques for the treatment of mitral valve disease (MVD) have continuously evolved; however, anatomical details like severe annular calcification remain challenging and require sophisticated surgical strategies. Among patients with symptomatic MVD referred for surgical valve repair or replacement, four presented with circumferential calcification of the mitral annulus precluding conventional surgical techniques. Successful treatment by implanting a balloon-expandable transcatheter aortic heart valve using an antegrade surgical access was performed...

OBJECTIVE:  To test the optimal antithrombotic regimen in patients with acute coronary syndrome. DESIGN:  Randomised controlled trial. SETTING:  Patients with acute coronary syndrome with and without ST segment elevation in 78 centres in Italy, the Netherlands, Spain, and Sweden. PARTICIPANTS:  7213 patients with acute coronary syndrome and planned percutaneous coronary intervention: 4010 with ST segment elevation and 3203 without ST segment elevation...

BACKGROUND: Few data are available on long-term follow-up of DES in the treatment of chronic total occlusion (CTO). The LEADERS CTO sub-study compared the long-term results in CTO and non-CTO lesions of a Biolimus A9™-eluting stent (BES) with a sirolimus-eluting stent (SES). METHODS: Among 1,707 patients enrolled in the prospective, multi-center, all-comers LEADERS trial, 81 with CTOs were treated with either a BES (n = 45) or a SES (n = 36). The primary endpoint was the occurrence of major adverse cardiac events (MACE): cardiac death, myocardial infarction (MI) and clinically-indicated target vessel revascularization (TVR)...

BACKGROUND: The clinical correlates and the prognostic significance of CAC in women undergoing percutaneous coronary intervention with DES remain unclear. METHODS: Patient-level data from female participants in 26 randomized trials of DES were pooled...

OBJECTIVES: To compare the efficacy of a proactive approach with a reactive approach to offer intensive smoking cessation intervention using motivational interviewing (MI). DESIGN: Before-after comparison in 2 academic hospitals with parallel comparisons in 2 control hospitals. SETTING: Academic hospitals in Switzerland. PARTICIPANTS: Smokers hospitalised for an acute coronary syndrome (ACS). INTERVENTION: In the intervention hospitals during the intervention phase, a resident physician trained in MI systematically offered counselling to all smokers admitted for ACS, followed by 4 telephone counselling sessions over 2 months by a nurse trained in MI...

AIMS: Transcatheter heart valve (THV) implantation in failed bioprosthetic valves (valve-in-valve [ViV]) offers an alternative therapy for high-risk patients. Elevated post-procedural gradients are a significant limitation of aortic ViV. Our objective was to assess the relationship between depth of implantation and haemodynamics. METHODS AND RESULTS: Commercially available THVs used for ViV were included in the analysis (CoreValve Evolut, SAPIEN XT and the Portico valve)...
