TCT-647 Hemodynamic valve deterioration following transcatheter aortic valve implantation: prevalence and predictors of elevated transvalvular gradients

Valve durability has become a major issue after transcatheter aortic valve replacement (TAVR) procedures. Elevated gradients have been proposed to be associated with hemodynamic valve dysfunction. We sought to investigate the prevalence and predictors of elevated gradients and the incidence of valve
