Background & Aims : Although aortic valve replacement (AVR) is the only effective treatment for patients with aortic stenosis (AS), it is generally recognized that the surgical risk increases with age.<BR>Methods : We examined the outcome of surgical management for AS in patients above 70 years of age in comparison with younger ones to determine whether age was a risk factor.<BR>Results : We obtained relatively good results in 3-and 5-year mortality (17% and 25%) in the elder group which were not significantly different from the younger group (5% and 13%). Perioperative factors were not significantly different between the two group. Elderly patients had significantly smaller body surface areas (BSAs) (1.43 ± 0.15 vs. 1.53 ± 0.16m<SUP>2</SUP>) and smaller valves (20.5 ± 1.8 vs. 22.0±2.0mm). The age was significantly correlated with the BSA (correlation coefficient=-0.433, p<0.001) and the valve size (Spearmans σ=-0.414, p<0.005). The valve size was also significantly correlated with the BSA (Spearmans σ=0.612, p< 0.0001).<BR>Conclusions : The risk of AVR in patients with AS was not significantly increased by age and AVR may be performed with good results in both short-and long-term outcomes.
