Doppler echocardiography in aortic stenosis AV Vmax: peak aortic velocity; AV Vmean: mean aortic velocity; AV maxPG: peak aortic gradient; AV mean PG: mean aortic gradient; AV VTI:
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
