The afternoon will bring the heart team on the floor discussing cases. Highlight for sure the imager in the next session when showing how to use 3D in several different situations.
Finally on Day 3 real hands 🙌 on with GE & Philips systems (workstation).

Day 2 will Focus on TV & RV function
Again live knob clicking but this time usin new Philips machine Before lunch break we will look into oHCM
After lunch we will bring the attention towards ICU topics and how Advanced Echo is helpful e.g. 👉subcostal window for 3D and again 👉 contrast Echo in ICU

After lunch we will focus on MV by answering several important questions as how 👉stress tests can help to unveil severity 👉 how translumination helps to see even small prolapse 👉 screening for M TEER & how to use M TEER even in mixed mitral valve 👉 closing looking again at intracardiac masses

Before the lunch break there is a clinical case corner looking at 👉combined AR & MR, 👉showing how TTE is helpful even if MR jet is eccentric and last but not least looking at 👉intra cardiac masses using echo contrast

Look at Aortic ring and aorta ascendens
👉in dilatation central jet due to central coaptation defect
3D:
To identify numbers of cusp and cusp position
March 13, 2025 at 5:53 PM
2D:
👉Look at cusp numbers and leaflet position using aortic annulus as reference plane bicuspid in the younger patients or tricuspid
👉prolapse of RCC
👉Folding of RCC
👉Torn Fenestration (look for oscillating parts in LVOT)
👉Cusp restriction
March 13, 2025 at 5:53 PM
Structural Integrity
👉LVEDS?
👉LV EF / GLS

Why? seen by 2D & 3D TTE first often no need for TEE in diagnostic work up

TEE needed if TTE inconclusive usually to look at valve morphology not for severity grading
March 13, 2025 at 5:53 PM
👉look at LV volumes > RV Volumes as a simple byproduct of LV EF a parameter we all believe in
👉look at forward LVOT & RVOT stroke volume

👉ALWAYS CALCULATE REG. FRACTION AS WE CAN, OFTEN NO NEED TO CALL FOR CMR TO TELL HOW MUCH AND BE HONEST IF YUO DO TEE ON HOW YUO GRADE SEVERITY
March 13, 2025 at 5:53 PM
👉PHT < 200 ms marks severe AR, but be aware of VTI trace, AR v max at least 4m/s, careful if jet is eccentric
👉GL asking for vena contracta best in LPLAX > 6 mm

👉Aorta descending flow reversal important to 👀 at, be careful in aneurysm as reversal flow may be less but still severe AR!
March 13, 2025 at 5:53 PM
How much AR is there?
👉GL do recommend PISA & regurgitation volume & fraction MANY PITFALLS (N. Merke MR & PISA can be applied also for AR) 👉 shorturl.at/O24x3
