Nicolaj C. Hansson et al. JACC 2016;68:2059-2069 THV Thrombosis: Detection by Multidetector Computed Tomography (7%) In this study cohort of 405 patients, larger transcatheter heart valve (THV) size and no post–transcatheter aortic valve replacement (TAVR) warfarin treatment was found to be associated with increased risk of THV thrombosis. Warfarin effectively reverted THV thrombosis and normalized THV function. Nicolaj C. Hansson et al. JACC 2016;68:2059-2069 American College of Cardiology Foundation
