Does severe prosthesis-patient mismatch increase long-term mortality and congestive heart failure in patients with small St Jude Medical aortic valve prostheses?
Severe prosthesis-patient mismatch in small St Jude Medical aortic valves predicts higher long-term mortality and heart failure, highlighting the need to maximize effective orifice area during aortic valve replacement.
Severe P-PtM is an independent predictor of higher long-term mortality and congestive heart failure in patients with small St Jude Medical aortic valve prostheses. For patients undergoing AVR who are at risk of severe mismatch, every effort should be made to use a larger prosthesis or to consider a prosthesis with a larger EOA.
