Multicenter Study Meta AnalysisPrior Percutaneous Coronary Intervention and Mortality in Patients Undergoing Surgical Myocardial Revascularization: Results From the E-CABG (European Multicenter Study on Coronary Artery Bypass Grafting) With a Systematic Review and Meta-Analysis.
The clinical impact of prior percutaneous coronary intervention (PCI) in patients requiring coronary artery bypass grafting (CABG) remains unsettled. We sought to determine whether prior PCI is associated with adverse outcome after CABG. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT02319083.

Multicenter StudyTreatment of Aortic Stenosis With a Self-Expanding, Resheathable Transcatheter Valve: One-Year Results of the International Multicenter Portico Transcatheter Aortic Valve Implantation System Study.
The aim of the Portico TAVI (transcatheter aortic valve implantation) system study was to evaluate outcomes ≤1 year after implantation of a novel resheathable, self-expanding TAVI system in a multicenter patient population with severe aortic stenosis (AS). ⋯ URL: https://www.clinicaltrials.gov. Unique identifier: NCT01493284.

Multicenter Study Comparative StudyPredicting Mortality After Transcatheter Aortic Valve Replacement: External Validation of the Transcatheter Valve Therapy Registry Model.
The Transcatheter Valve Therapy (TVT) registry model was recently developed to predict the risk of in-hospital mortality in patients undergoing transcatheter aortic valve replacement. We sought to externally validate the model in an independent data set of consecutively enrolled patients in the Swiss Transcatheter Aortic Valve Implantation registry. ⋯ In a large, multicenter, non-US cohort of patients with transcatheter aortic valve replacement, the validation of the TVT registry model demonstrated moderate discrimination and good calibration for the prediction of in-hospital and 30-day mortality. As a result, the TVT registry model should be considered an alternative to the Society of Thoracic Surgeons Predicted Risk of Mortality score for decision making and assessment of early outcome in patients eligible for transcatheter aortic valve replacement.

Multicenter StudyAcute and Midterm Outcomes of Transcatheter Pulmonary Valve Replacement for Treatment of Dysfunctional Left Ventricular Outflow Tract Conduits in Patients With Aortopulmonary Transposition and a Systemic Right Ventricle.
Transcatheter pulmonary valve replacement (TPVR) is an established therapy for dysfunctional right ventricular (RV) outflow tract conduits. TPVR in patients with congenitally corrected transposition of the great arteries, subpulmonary left ventricle, and left ventricular outflow tract (LVOT) conduit dysfunction has not been studied. Unique anatomic and physiological aspects of this population may contribute to distinct risks and outcomes. ⋯ TPVR in dysfunctional LVOT conduits is feasible but associated with an important rate of TPV nonimplantation and procedural serious adverse events. Worsening systemic RV function and tricuspid regurgitation may develop after LVOT TPVR.

Multicenter Study Observational StudyWhite Blood Cell Count and Major Adverse Cardiovascular Events After Percutaneous Coronary Intervention in the Contemporary Era: Insights From the PARIS Study (Patterns of Non-Adherence to Anti-Platelet Regimens in Stented Patients Registry).
Elevated white blood cell (WBC) count is associated with increased major adverse cardiovascular events (MACE) in the setting of acute coronary syndrome. The aim of this study was to evaluate whether similar associations persist in an all-comers population of patients undergoing percutaneous coronary intervention in the contemporary era. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT00998127.
