AS: Aortic Valve Area (DVI)| Calculate by QxMD | QxMD
The Doppler Velocity Index (DVI) is useful for assessing aortic prosthetic valve function as well as screening for valve obstruction. It is calculated as the ratio of the subvalvular velocity obtained by PW Doppler and the maximum velocity obtained by CW Doppler across the prosthetic valve.
Evaluation of Prosthetic Valves: Challenges •Large range in what is considered normal •Mean Gradients produced depend on size and type of valve. •For any particular patient… it is difficult to differentiate normal from abnormal, hence the need for comparison to older studies

A New Dimension in Treating Aortic Stenosis: DVI in the Battle of …
2021年7月1日 · Severe aortic stenosis (AS) has traditionally been treated using surgical aortic valve replacement (SAVR) as standard of care, and transcatheter aortic valve replacement (TAVR) was initially introduced as a therapeutic choice for …

Another quantitative measurement is the Doppler Velocity Index (DVI). The DVI is a dimensionless index that is great to use in the presence of prosthetic valves because the value is not flow dependent and is less dependent on valve …

Aortic Valve Area by Continuity Equation - E-Echocardiography
Activate the Aortic Valve analysis package and select LVOT diameter and enter the value of the LVOT diameter. Obtain a continuous wave doppler of the aortic valve. The optimal view is the deep transgastric AVLAX view or the transgastric AVLAX view.
