BACKGROUND The impact of aortic prosthesis-patient mismatch (P-PtM) on long-term survival is unclear. METHODS AND RESULTS Between 1985 and 2000, 388 patients at Mayo Clinic in Rochester, Minn, underwent aortic valve replacement (AVR) with 19- or 21-mm St Jude Medical prostheses and had transthoracic echocardiography within 1 year after AVR. Mean age of patients was 62+/-13 years; 69% were female. Prosthesis effective orifice area (EOA) was derived from the continuity equation. P-PtM was… CONTINUE READING
