BACKGROUND: Current guidelines suggest that coronary artery bypass grafting (CABG) should be the preferred revascularization method for unprotected left main coronary artery stenosis. In light of evidence from recent randomized trials, we assessed whether percutaneous coronary intervention (PCI) using drug-eluting stents is as safe and effective as CABG for the treatment of unprotected left main coronary artery disease. METHODS AND RESULTS: Digital databases and manual searches were performed for randomized trials comparing PCI and CABG for unprotected left main coronary artery stenosis...

BACKGROUND: The Navvus pressure sensor-equipped microcatheter allows to measure functional stenosis severity over a work-horse guidewire and is used as a more feasible alternative to regular sensor-equipped wires. However, Navvus is larger in diameter than contemporary sensor-equipped guidewires and may, thereby, influence functional measurements. The present study evaluates the hemodynamic influence of the Navvus microcatheter. METHODS AND RESULTS: In patients with intermediate coronary stenosis, coronary pressure and flow velocity were measured using a dual sensor-equipped guidewire before and after introduction of Navvus...

BACKGROUND: Distal coronary to aortic pressure ratio (Pd/Pa) and instantaneous wave-free ratio (iFR) are indices of functional significance of a coronary stenosis measured without hyperemia. It has been suggested that iFR has superior diagnostic accuracy to Pd/Pa when compared with fractional flow reserve (FFR).We hypothesized that in comparison with FFR, revascularization decisions based on either binary cutoff values for iFR and Pd/Pa or hybrid strategies incorporating iFR or Pd/Pa will result in similar levels of disagreement...

BACKGROUND: The objective of this study was to assess the efficacy of sealing intermediate nonobstructive coronary saphenous vein graft (SVG) lesions with drug-eluting stents (DES; paclitaxel- or everolimus-eluting stents) for reducing major adverse cardiac events (MACE). METHODS AND RESULTS: This was a randomized controlled multicenter clinical trial that enrolled patients with a previous coronary artery bypass graft who had developed at least 1 intermediate nonobstructive SVG lesion (30%-60% diameter stenosis by visual estimation)...

BACKGROUND: Associations between hospital volume and the risk of stroke or death following carotid endarterectomy (CEA) and carotid artery stenting (CAS) on a national level in Germany were analyzed. METHODS AND RESULTS: Secondary data analysis using microdata from the nationwide statutory German quality assurance database on all surgical or endovascular carotid interventions on the extracranial carotid artery between 2009 and 2014. Hospitals were categorized into empirically determined quintiles according to the annual case volume...

BACKGROUND: There are only little data available on the comparison of clinical outcomes between a 1-stent strategy (1-SS) and a 2-stent strategy (2-SS) for percutaneous coronary intervention in unprotected distal left main disease. METHODS AND RESULTS: Between April 2005 and August 2011, we recruited 937 consecutive unprotected distal left main patients treated with drug-eluting stents (1-SS, 608 patients; 2-SS, 329 patients). Major adverse cardiovascular events were defined as all-cause death, myocardial infarction, or target lesion revascularization (TLR) during the median follow-up period of 1592 days...

The optimal antithrombotic treatment regimen for patients with atrial fibrillation undergoing percutaneous coronary intervention with stent implantation is an emerging clinical problem. Currently, there is limited evidenced-based data on the optimal antithrombotic treatment regimen, including antiplatelet and anticoagulant therapies, for these high-risk patients with practice guidelines, thus, providing limited recommendations. Over the past years, expert consensus documents have provided guidance to clinicians on how to manage patients with atrial fibrillation undergoing percutaneous coronary intervention...

BACKGROUND: There is general agreement that the optimal duration of dual antiplatelet therapy (DAPT) in patients treated with drug-eluting stents should be individualized. We hypothesized that the extent of coronary artery disease may affect the clinical outcomes of DAPT. METHODS AND RESULTS: We pooled patient-level data from 5 large, randomized trials comparing short-term DAPT with prolonged therapy. From the data, we identified 5476 patients who received newer-generation drug-eluting stents...

BACKGROUND: Aortic valve stenosis may influence fractional flow reserve (FFR) of concomitant coronary artery disease by causing hypertrophy and reducing the vasodilatory reserve of the coronary circulation. We sought to investigate whether FFR values might change after valve replacement. METHODS AND RESULTS: The functional relevance of 133 coronary lesions was assessed by FFR in 54 patients with severe aortic valve stenosis before and after transcatheter aortic valve implantation (TAVI) during the same procedure...

BACKGROUND: Guidelines recommend the use of adenosine diphosphate receptor inhibitor (ADPri) therapy for 1 year postacute myocardial infarction; yet, early cessation of therapy occurs frequently in clinical practice. METHODS AND RESULTS: We examined 11 858 acute myocardial infarction patients treated with percutaneous coronary intervention discharged alive on ADPri therapy from 233 United States TRANSLATE-ACS study (Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome) participating hospitals to determine the prevalence of early ADPri cessation (within 1 year), patient-reported reasons for cessation, and associated risk of major adverse cardiovascular events at 1 year...

BACKGROUND: There is little evidence regarding the efficacy and safety of bioresorbable scaffolds (BRS) for the percutaneous treatment of chronic total occlusions. METHODS AND RESULTS: We performed a multicenter registry of consecutive chronic total occlusion patients treated with BRS (Absorb; Abbott Vascular) and second-generation drug-eluting stents (DES) at 5 institutions. Long-term target-vessel failure (a composite of cardiac death, target-vessel myocardial infarction, and ischemia-driven target-lesion revascularization) was the primary end point...

BACKGROUND: The presence of coronary artery ectasia (CAE) is influenced by genetic factors and related to the presence of aneurysms in other vascular beds. Bicuspid aortic valve (BAV) disease is frequently accompanied by ascending aortic aneurysm. Because the aortic valve and the proximal parts of the coronary arteries share a common embryonic origin, we hypothesized that CAE is associated with BAV disease. METHODS AND RESULTS: One hundred seventy-seven patients with suspected aortic valve disease (n=94 BAV, n=83 tricuspid aortic valve) underwent both cardiac magnetic resonance imaging and coronary angiography...
