title: Valvular disease. Super size me? Annular size and paravalvular leak after TAVR.
abstract: Paravalvular aortic regurgitation (PAR) after transcatheter aortic valve replacement is common and independently associated with increased morbidity and mortality. The determinants of PAR are uncertain, but new data extend our understanding, and a simple practice change in preprocedural imaging could help dramatically to reduce the incidence of this important complication.
