BSA-based PPM thresholds may guide TAVI sizing in AF; leaves open outcome validation before practice change.
Graphical Abstract: Transcatheter Valve Size and Clinical Outcomes in Patients with Atrial Fibrillation Undergoing TAVI. Legend: Predicted patient prosthesis mismatch (PPM) was defined as effective orifice area (EOA), per manufacturer specifications, divided by the body surface area (BSA). The suggested cutoffs for insignificant, moderate, and severe PPM were stratified by body mass index (BMI). For BMI <30 kg/m2, the corresponding EOA/BSA thresholds were >0.85, 0.66 to 0.85, and ≤0.65 cm2/m2, respectively.

Hemelrijk et al. (2026) conducted an observational in Atrial Fibrillation Undergoing Transcatheter Aortic Valve Implantation. Predicted patient prosthesis mismatch (PPM) was evaluated on Clinical Outcomes. The abstract defines predicted patient prosthesis mismatch cutoffs based on body mass index for patients with atrial fibrillation undergoing TAVI, but reports no clinical outcomes.
