Multicenter StudyProsthesis-patient mismatch is associated with higher operative mortality following aortic valve replacement.
Prosthesis-patient mismatch (PPM) occurs when the valve prosthesis implanted at surgery is too small in relation to patient's body size, causing high transvalvular gradients. We investigated if severe PPM is related to early morbidity and mortality after aortic valve replacement (AVR). ⋯ PPM was associated with increased operative mortality. PPM should be avoided where possible as it may reduce operative mortality following AVR.
