This literature review evaluated 21 studies that included nearly 4000 patients having undergone transcatheter aortic valve implantation (TAVI), specifically focusing on prosthesis-patient mismatch (PPM). Overall prevalence of PPM was 35%, with 8% of patients having severe PPM. PPM occurred less often after TAVI than after surgical AVR. PPM was not associated with increased long-term mortality.
