All continuous variables were converted to binary predictors using the median of the overall study population as a cut off.
*Symptomatic defined as having ≥1 of the following (presumed to be AS related): chest pain, shortness of breath, dizziness on exertion/syncope.
†Adjusted for age, severefrailty, renal insufficiency, COPD, Vmax, mean AV gradient, LVEF, mitral regurgitation grade III/IV and tricuspid regurgitation grade III/IV.
‡Creatinine clearance rate <50 mL/min or dialysis.
§Insulin dependent.
¶2-year life expectancy< 25% was assessed by the dedicated nurses and physicians.
