Five-Year Outcomes of Measured and Predicted Prosthesis-Patient Mismatch following Transcatheter Aortic Valve Implantation.

Data on the long-term outcomes of prosthesis patient mismatch (PPM) after transcatheter aortic valve implantation (TAVI) remain controversial. This study aimed to investigate the incidence and clinical outcomes of measured PPM (PPM) and predicted PPM (PPM) in patients who underwent TAVI. This is a retrospective analysis of 3,016 patients who underwent TAVI at a large health care system between 2012 and 2021.
