Either citation can be used when citing this article.The VARC (Valve Academic Research Consortium) for transcatheter aortic valve replacement set the standard for selecting appropriate clinical endpoints reflecting safety and effectiveness of transcatheter devices, and defining single and composite clinical endpoints for clinical trials. No such standardization exists for circumferentially sutured surgical valve paravalvular leak (PVL) closure. This document seeks to provide core principles, appropriate clinical endpoints, and endpoint definitions to be used in clinical trials of PVL closure devices. The PVL Academic Research Consortium met to review evidence and make recommendations for assessment of disease severity, data collection, and updated endpoint definitions. A 5-class grading scheme to evaluate PVL was developed in concordance with VARC recommendations. Unresolved issues in the field are outlined. The current PVL Academic Research Consortium provides recommendations for assessment of disease severity, data collection, and endpoint definitions. Future research in the field is warranted.All authors: Berrebi A, Borer JS, Cutlip DE, Fontana G, Gerosa G, Hahn RT, Ibrahim R, Jelnin V, Jilaihawi H, Jolicoeur EM, Kliger C, Kronzon I, Leipsic J, Leon MB, Maisano F, Millan X, Nataf P, O'Gara PT, of the Paravalvular Leak Academic Research Consortium, Pibarot P, Ramee SR, Rihal CS, Rodes-Cabau J, Ruiz CE, Serruys PW, Sorajja P, Suri R, Swain JA, Turi ZG, Tuzcu EM, Weissman NJ, Zamorano JLFiscal year: FY2017Digital Object Identifier: Date added to catalog: 2017-05-06
