Aortic valve Effective regurgitant orifice area by US.doppler+Calculated by volumetric method

AV EROA DOP+Calc by vol

Definition

  • The effective regurgitant orifice area (EROA) is the size of the defect where the valve leaflets are not aligning normally (coaptation defect). The severity of regurgitation is related to the EROA. EROA can be calculated by the Volumetric method as regurgitant volume divided by the velocity time integral of the regurgitant jet velocity (VTIRegJet), which is recorded by continuous wave Doppler.
