Abstract
Prosthesis-patient mismatch (PPM) is defined as a small effective orifice area (EOA) of a normally functioning prosthetic valve in relation to patient body size. Even moderate impediment to forward flow has been associated with an increase in all-cause mortality. We report an unusual cause of PPM where a transcatheter implantation of a large EOA valve in an aortic position results in relative PPM in a patient with morbid obesity. © 2016 Wiley Periodicals, Inc.
