Echocardiographic phases of chronic aortic regurgitation

Echocardiographic phases of chronic aortic regurgitation
  Compensated Transitional Decompensated*
Dimensions
End-diastolic dimension (mm) <60 60 to 70 >75
End-systolic dimension (mm) <45 45 to 50 >55
Volumes
End-diastolic volume (mL/m2) <120 130 to 160 >170
End-systolic volume (mL/m2) <50 50 to 60 >60
Left ventricular function
Ejection fraction (percent) >55 51 to 55 ≤50
Fractional shortening (percent) >32 30 to 31 <29
Patients with intermediate values between transitional and decompensated disease (end-diastolic dimension 70 to 75 mm and end-systolic dimension 50 to 55 mm) can be referred for exercise testing. Those with an abnormal response are referred for valve replacement, while those with a normal response to exercise are closely monitored.
* Patients with decompensated aortic regurgitation are referred for aortic valve replacement. Lower threshold values can be considered in patients of small stature.
