Table 3.18-2. Echocardiographic follow-up of patients with asymptomatic aortic regurgitation

Severity of regurgitation

Left ventricular function


Mild or moderate

Normal LVEF and LVESD

Every 2 years


LVEDD 60-65 mm

Every yeara

LVEDD >65 mm

Every 6 months

Aortic dilation <50 mm

Every yearb

a The first follow-up visit within 6 months of the diagnosis.

b Increases >3 mm should be confirmed on CT.

CT, computed tomography; LVEDD, left ventricular end-diastolic diameter; LVEF, left ventricular ejection fraction; LVESD, left ventricular end-systolic diameter.
