BACKGROUND Usage of biological prosthesis is increasing in surgical aortic valve replacement (SAVR). Recent U.S. guidelines recommend either biological or mechanical prosthesis for SAVR in patients aged 50-70 years. We set out to study long-term outcomes of mechanical vs. biological prosthetic valves in this patient group. METHODS All patients (excluding infective endocarditis and other concomitant surgery than CABG) aged 50-70 with first-time SAVR in Finland between 2004-2014 were… CONTINUE READING
