Webb12 juli 2024 · Prosthesis-patient mismatch (PPM) is defined by an effective orifice area (EOA) too small in relation to patient’s body surface area (BSA), therefore often resulting in high residual transvalvular pressure gradients (1).PPM is generally categorized on the basis of the indexed EOA (EOAi) (ie, the EOA divided by the patient’s BSA). WebbAbstract. Background Several studies have reported high rates of prosthesis–patient mismatch (PPM) after aortic valve replacement (AVR) with the Mosaic prosthesis. This work assesses the incidence of PPM after AVR with a modified version of the Mosaic prosthesis, the Mosaic Ultra. Methods We performed a retrospective analysis of the data …
