Importance: Identifying high-performing surgical valve centers with the best surgical outcomes is challenging. Hospital surgical volume is a frequently used surrogate for outcomes. However, its ability to distinguish low-performing and high-performing hospitals remains unknown. Objective: To examine the association of hospital procedure volume with hospital performance for aortic and mitral valve (MV) surgical procedures. Design, Setting, and Participants: Within an all-payer nationally representative data set of inpatient hospitalizations, this study identified 682 unique hospitals performing surgical aortic valve replacement (SAVR) and MV replacement and repair with or without coronary artery bypass grafting (CABG) between 2007 and 2011...

BACKGROUND: Although bifurcation percutaneous coronary intervention (PCI) is associated with lower procedural success rates and higher risk of complications, there are little data regarding outcomes after successful bifurcation PCI with contemporary stents and techniques. Whether residual platelet reactivity (PR) affects outcomes differently after bifurcation versus non-bifurcation PCI is also unknown. We studied the association between bifurcation PCI, PR, and clinical outcomes among patients undergoing successful PCI with drug-eluting stents...

The presence of severe coronary artery calcification is associated with higher rates of angiographic complications during percutaneous coronary intervention (PCI), as well as higher major adverse cardiac events compared with non-calcified lesions. Incorporating orbital atherectomy (OAS) for effective preparation of severely calcified lesions can help maximize the benefits of PCI by attaining maximal luminal gain (or stent expansion) and improve long-term outcomes (by reducing need for revascularization). Areas covered: In this manuscript, the prevalence, risk factors, and impact of coronary artery calcification on PCI are reviewed...

BACKGROUND: Fractional flow reserve (FFR), an index of the hemodynamic severity of coronary stenoses, is derived from invasive measurements and requires a pressure-monitoring guidewire and hyperemic stimulus. Angiography-derived FFR measurements (FFRangio) may have several advantages. The aim of this study is to assess the diagnostic performance and interobserver reproducibility of FFRangio in patients with stable coronary artery disease. METHODS AND RESULTS: FFRangio is a computational method based on rapid flow analysis for the assessment of FFR...

BACKGROUND: Whether the consequences of diabetes mellitus (DM) are worse for women than for men treated with drug-eluting stents (DES) and antiplatelet therapy remain unclear. METHODS: Patients from the Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents study were stratified according to sex and DM status. We investigated the sex-specific effect of DM on high on-clopidogrel platelet reactivity (HPR), defined as a P2Y12 reaction units ≥208, and the adjusted association of DM on the 2-year risk for coronary thrombotic events (CTE), defined as spontaneous myocardial infarction or definite or probable stent thrombosis...

Coronary perforation is a potential complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We analyzed 2,097 CTO PCIs performed in 2,049 patients from 2012 to 2017. Patient age was 65 ± 10 years, 85% were men, and 36% had prior coronary artery bypass graft surgery. Technical and procedural success were 88% and 87%, respectively. A major periprocedural adverse cardiovascular event occurred in 2.6%. Coronary perforation occurred in 85 patients (4.1%); The frequency of Ellis class 1, 2, and 3 perforations was 21%, 26%, and 52%, respectively...

Patients at high risk of thrombotic events after percutaneous coronary intervention (PCI) may potentially benefit from intensified antiplatelet therapy. However, more potent antiplatelet therapy would be expected to only overcome risk that is mediated by high platelet reactivity (PR). We used mediation analysis to determine the contribution of residual PR to the 2-year risk of major adverse cardiac events (MACE; the composite of cardiac death, myocardial infarction, or stent thrombosis) associated with clinical risk factors after PCI with drug-eluting stents (DES) in 8,374 patients from the prospective, multicenter Assessment of Dual AntiPlatelet Therapy with Drug-Eluting Stents (ADAPT-DES) registry...
