Key result
Primary AVR in octogenarians yields ~70% lower hospital mortality than EuroSCORE predictions.

Does primary aortic valve replacement result in acceptable mortality and long-term survival in patients aged 80 years and older?
Absolute Event Rate: 4.9% vs 16.2%
p-value: p=< 0.01
Primary aortic valve replacement in octogenarians is associated with excellent long-term survival and lower hospital mortality than predicted by conventional risk scores.
Nikolaidis et al. (2011) conducted a cohort in Aortic valve disease requiring replacement (n=345). Primary aortic valve replacement (AVR) with or without CABG vs. Predicted mortality by logistic EuroSCORE was evaluated on Hospital mortality (p=< 0.01). Primary aortic valve replacement in octogenarians resulted in a hospital mortality of 4.9%, significantly lower than the 16.2% predicted by the logistic EuroSCORE (p < 0.01).
