Predictors of Rapid Progression and Clinical Outcome of Asymptomatic Severe Aortic Stenosis

Abstract

The annual progression rate of severe AS was -0.05 cm(2)/year for AVA and 0.22 m/s/year for AV-Vel. Patients with first-year rapid progression or severely calcified aortic valve should be carefully observed while considering an early operation. (Circ J 2016; 80: 1863-1869).
