This condition may be classified as being due to cusp abnormality or to aortic ring dilatation.
NICE guidance with respect to asymptomatic aortic regurgitation states (1):
- consider referring adults with asymptomatic severe aortic regurgitation for intervention, if suitable, if they have either of the following:
- LVEF less than 55% or
- end systolic diameter (ESD) of more than 50 mm or end systolic diameter index (ESDI) more than 24 mm/m2 on echocardiography
