Aortic Valve (rev 10/17/19)
Indications: Aortic valve disease, stenosis, regurgitation. Quantification of regurgitant volume, peak gradient, planimetry.

NOTES
**optional repeat 3 chamber
if 3 chamber is off axis with 3 point plan, then use coronal LVOT and 4 chamber to repeat plan the 3 chamber
**optional Aortic Valve GRE CINE
If TrueFISP cine is suboptimal, often due to valve leaflet Ca++
**optional Aortic Valve RADIAL CINE
no phase wrap, so small square FOV (~220), easy to plan
