Key result
Severe prosthesis-patient mismatch after AVR is linked to substantially higher basal surface area.
Why the study?
Prosthesis-patient mismatch is a frequent issue after aortic valve replacement, and the residual high transprosthetic pressure gradient could impede left ventricular mass regression.
Does prosthesis-patient mismatch (EOAI < 0.85 cm2/m2) after aortic valve replacement for aortic stenosis affect left ventricular mass regression at six months?

Higher basal surface area in severe PPM after AVR may inform prosthesis choice; leaves open effects on LV mass regression at six months.
Objective: Prosthesis-patient mismatch (PPM) of the aortic prosthesis is frequent trouble following aortic valve replacement (AVR). The residual high transprosthetic pressure gradient (PG) could interrupt left ventricular mass regression (LVMR). The purpose of this study was to assess the frequency of PPM as well as its impact on LVMR postoperatively. Methods: 106 patients were prospectively evaluated after AVR for aortic stenosis (AS) from Jan 2016 to Dec 2021. Patients were classified into three groups based on the effective orifice area index (EOAI) (cm2/m2); Group A (≥0.85), B (0.8-0.84), and C (< 0.8). Follow-up of LVMR was performed postoperatively on all patients after six months. Results: We didn’t record significant changes in basic data among studied groups away from the basal surface area, which was substantially higher in group C (Mean 2.4, P

Alawady et al. (2022) conducted a cohort in Aortic stenosis (n=106). Prosthesis-patient mismatch (PPM) vs. No prosthesis-patient mismatch was evaluated on Left ventricular mass regression (LVMR). In patients evaluated after aortic valve replacement, basal surface area was substantially higher in the severe prosthesis-patient mismatch group (Mean 2.4).
