Description
Summary:Compared with SAVR, TAVR resulted in larger EOA and less prosthesis-patient mismatch (PPM), but consistent with other studies (13), more aortic insufficiency (total and paravalvular). [...]the type of aortic valve replacement had important, but not entirely predictable, structural and functional consequences. [...]the aortic regurgitation index (the ratio of the gradient between aortic diastolic pressure and LV end-diastolic pressure to systolic blood pressure) decreased with increasing severity of aortic regurgitation and predicted the 1-year mortality after transcatheter aortic valve implantation independent of the echocardiographic degree of paravalvular leak (21). [...]efforts to recognize, quantify, and reduce the incidence of prosthetic aortic regurgitation are critical.
