The aim of our study was to determine survival after aortic valve replacement (AVR) with or without concomitant coronary artery bypass surgery at Oslo University Hospital Ullevål and compare this to the general Norwegian population and to the EuroSCORE predicted mortality. 497 patients with a mean age of 70.4 years were followed for up to 3 years postoperatively. Overall, in operated patients above 75 years the 3 years survival rate was 85.4 % versus 79.1 % in the general population, whereas in patients under 65 years old the 3 years survival rate was 94.8 % versus 98.2 % in the general population. In patients subjected to isolated AVR, the numbers were 90.0 % versus 79.1 % (< 75 years) and 94.2 % versus 98.2 % (< 65 years). There was no significant difference in survival in the middle age group in comparison with the general population. The overall survival rate was 96.2 % at 30 days, 94.2 % at one year, 91.5 % at two years, and 88.2 % at three years. Mortality generally correlated with EuroSCORE prediction, but EuroSCORE overestimated mortality by a factor of 1.6. Conclusions: Patients in the highest age group (>75 years) exhibited significantly improved survival compared to the general population. Patients in the lowest age group (<65 years) exhibited significantly lower survival compared to general population. Furthermore, although mortality correlated to EuroSCORE also beyond 30 days, it overestimated mortality by 1.6 times.
