- LVOT and RVOT diameter
- RVOT TVI for Cardiac Output calculations
- Is the Aortic Opening?
- Assessment of AR, MR and TR

>> Apical/Para Apical Window

- Apical inflow cannula (2D and Color Flow)
- Assessment of MR,TR and AR
- RV size and function
- LVOT PW TVI (if aortic valve is opening)
- Pulse wave and color flow Doppler of inflow cannula
