Outcome of Patients With Low-Gradient “Severe” Aortic Stenosis and Preserved Ejection Fraction

Do patients with low-gradient "severe" aortic stenosis and normal ejection fraction have similar outcomes to patients with moderate stenosis?

Population

Patients with low-gradient "severe" aortic stenosis and normal ejection fraction

Comparator

Patients with moderate aortic stenosis

Outcome

Outcome (unspecified)

Low-gradient severe aortic stenosis with preserved ejection fraction behaves clinically like moderate aortic stenosis.

Patients with low-gradient "severe" aortic stenosis and normal ejection fraction have an outcome similar to that in patients with moderate stenosis.
