Key result
Isolated aortic valve replacement for aortic stenosis resulted in a 10-year survival of 63%, with left ventricular failure (p<0.0002) and age (p<0.009) identified as independent predictors.

Supports preoperative risk stratification by LV function and age in aortic stenosis; leaves open applicability to current prostheses and techniques.
Cohort (n=122)
Left ventricular failure, age, pulse pressure, and cardio-thoracic index are independent predictors of long-term survival after aortic valve replacement for aortic stenosis.
Lund et al. (1987) conducted a cohort in Aortic valve stenosis (n=122). Isolated aortic valve replacement was evaluated on 10-year cumulative survival. Isolated aortic valve replacement for aortic stenosis resulted in a 10-year survival of 63%, with left ventricular failure (p<0.0002) and age (p<0.009) identified as independent predictors.
