^*Aortic valve area determined by the continuity equation method.

^†Pressure gradients calculated from echocardiography velocity measurements using the Bernoulli equation. Pressure gradients were not available in subjects without aortic stenosis.

^‡Aortic valve area (AVA) in subjects without known aortic stenosis was estimated from the relationship: AVA - −2.64 + 0.04 × (height in cm) −0.47 × w (w = 0 for male, w = 1 for female) (23).

n/a = not applicable.
