Since patients with low gradient aortic stenosis are at higher risk for surgical replacement, more information concerning whom to select for surgery is desirable. Monin and colleagues from 6 centers in France studied 136 symptomatic patients with aortic valve area < 1.0 cm2, low cardiac index and a mean aortic pressure gradient < 40 mm Hg.
