Key result
Aortic valve replacement in patients >70 years old yielded 3- and 5-year mortality rates (17% and 25%) that were not significantly different from younger patients (5% and 13%).
Why the study?
Does age >70 years increase mortality risk in patients undergoing aortic valve replacement for aortic stenosis?
Population
Patients with aortic stenosis undergoing surgical management, divided into elderly and younger patients.
Comparison
Aortic valve replacement in patients >70 years… vs Aortic valve replacement (AVR) in younger patients
Design
Cohort
Follow-up
5 years

May not increase post-AVR mortality in patients >70; challenges consensus yet leaves open need for prospective confirmation.
Observational
Does age >70 years increase mortality risk in patients undergoing aortic valve replacement for aortic stenosis?
Absolute Event Rate: 25% vs 13%
Ogata et al. (2002) conducted an observational in Aortic stenosis. Aortic valve replacement vs. Younger patients was evaluated on 5-year mortality. Aortic valve replacement in patients >70 years old yielded 3- and 5-year mortality rates (17% and 25%) that were not significantly different from younger patients (5% and 13%).
