BACKGROUND The purpose of this study was to determine the impact of prosthesis-patient mismatch on long-term survival after mitral valve replacement. METHODS From 1992 to 2008, 765 patients underwent bioprosthetic (325; 42%) or mechanical (440; 58%) mitral valve replacement, including 370 (48%) patients older than 65 years of age. Prosthesis-patient mismatch was defined as severe (prosthetic effective orifice area to body surface area ratio <0.9 cm(2)/m(2)), moderate (0.9 to 1.2 cm(2)/m(2… CONTINUE READING
