How to estimate the Aortic Valve Area using continuity equation? 

.785× D² not. .785×2×D❤

Just to precise a point, continuity equation states that FLOW1 x SURFACE1 =FLOW2 x SURFACE2 . Our two entities are LVOT and AV. Here we measured LVOT as surface1 and the LVOT VTI gives us the FLOW 1 (through LVOT). With AV VTI we get FLOW2 (the flow through the Aortic valve). We get AVA (SURFACE2) by a rule of 3.

these videos are very helpful! you explain very well!! please do this for mitral insufficiency🙏

Everyone make this very difficult but you make it very easy...thank u...plz upload other vavular and congenital diseases too .....

The LVOT cross sectional area is calculated like this It's 0.785 multiplied by the (LVOT diameter by the power of two)
