BACKGROUND: Little is known about the gender differences of patients undergoing aortic valve replacement (AVR) for isolated severe aortic stenosis. METHODS AND RESULTS: 408 consecutive patients (215 women and 193 men; p=0.9) were analysed. At presentation, women were older (73.7+/-9.3 years vs men 66.5+/-11.5 years; p<0.001), more symptomatic (New York Heart Association (NYHA) class: women 2.3+/-0.7 vs men 2.0+/-0.65; p<0.001), and presented with smaller valve areas (women 0.6+/-0.2 cm(2) vs men 0.7+/-0.2 cm(2); p<0.001) and higher mean pressure gradients (women 67.3+/-19.2 mm Hg vs men 62.2+/-20.0 mm Hg, p=0.001). Despite older age and more advanced disease in women, operative mortality did not differ. Survival after AVR by Kaplan-Meier analysis tended to be even better in women (92.8%, 89.8%, 81.4% vs men 89.1%, 86.6%, 76.3% at 1, 2 and 5 years, p=0.31). After division into age quintiles, the outcome of women was significantly better in patients older than 79 years (p=0.005). After adjustment for clinical characteristics, gender did not predict operative mortality and late outcome. Despite physical improvement in both groups after surgery, women remained more symptomatic (NYHA class: women 1.6+/-0.7 vs men 1.3+/-0.4; p=0.001). CONCLUSION: Although women referred to AVR are older and more symptomatic, operative and long-term mortality are not increased. In the oldest age group of 79 years and older, women even have a better outcome, presumably due to a longer mean life expectancy.
