A person with chronic aortic regurgitation may benefit from surgical intervention if certain risk factors are present.


Indications for surgical correction of aortic regurgitation:

(1) symptomatic regurgitation (NYHA class III or IV = marked restriction in activity or totally incapacitated)

(2) left ventricular systolic dysfunction (ejection fraction < 50%)

(3) severe regurgitation with left ventricular dilatation

(3a) left ventricular end-systolic diameter on echocardiography > 55 mm, OR

(3b) left ventricular end-diastolic diameter > 70 mm


For borderline patients, an abnormal exercise capacity would favor surgical intervention.
