Prosthesis–Patient Mismatch After Transcatheter Aortic Valve Implantation

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.
