THE IMPACT OF AORTIC VALVE VELOCITY AND MEAN GRADIENT ON THE INCIDENCE AND SEVERITY OF PROSTHESIS PATIENT MISMATCH FOLLOWING TAVR

Prosthesis patient mismatch (PPM) occurs due to a small prosthetic valve for the patient's body size leading to elevated prosthetic aortic valve velocity (AVvel) and mean gradient (MG). Guidelines recommend using AVvel and indexed aortic valve area (iAVA) to diagnose PPM. Post TAVR, PPM has been
