Severe aortic regurgitation – Echo Severe aortic regurgitation: Echocardiogram in parasternal long axis (PLAX) view shows dilated left ventricle (LV), left atrium (LA), aorta (Ao) and a small
Aortic flow velocity by Doppler echo is routinely measured and is useful to assess aortic gradient in aortic stenosis. It is also useful in calculating valve area by
Gradient in aortic stenosis can be estimated from:
a. Sub costal view and PSAX
b. Apical 5C view and suprasternal view
c. PSAX view and PLAX view
d. Subcostal view and PSAX
