Thank you to all #SCA2018EchoWeek attendees and faculty for spending the week with us in Atlanta. The week was a success and we were glad to see everyone there!
My job is not to regurgitate textbooks, but to make you think differently!
I don’t care if you agree with me, or if you disagree with me, as long as you walk out of here thinking differently!

Evaluating AS, workflow:
1. If valve looks severe and max velocity is over 4 m/s - I’m done!
2. Mean grad over 40 - I’m done
3. Mean gradient 20-40 82% have severe AS by AVA

Difficult measuring the LVOT precisely, but important for aortic valve calculation, because garbage in - then squared - gives a whole pile of shit #SCA2018EchoWeek
50% of Myocardial Infarctions get some degree of Mitral Regurgitation #SCA2018EchoWeek
Congenital heart disease treatment is making great progress.
Olympic gold medalist Shaun White had Fallot's tetralogy(!)
As survival improves, you'll see more GUCH pts in the future. #SCA2018EchoWeek
RV assessment, might be better with 3D in future. Now with 2D it is:
difficult to assess
only assess limited portions (TAPSE etc)
Longitudinal contraction always reduced after bypass.

Prosthetic valves will always make some flow acceleration. Central orifice of some mechanical valves will give high speeds that drop off quickly. Not indicative of stenosis. #SCA2018EchoWeek
By definition, LVOT is measured from inner edge to inner edge #SCA2018EchoWeek
Ultrasound image based on many assumptions. Artefacts often “Violation of assumptions” #SCA2018EchoWeek
@thomas1973 man so much 🥩 in these tweets from #SCA2018EchoWeek !
is a butcher presenting or what?!
thanks for live sharing the points!
(kind of wish you were live steaming)

Use strain for checking abnormal EKG, as you should see Regional Wall Motion Abnormalities if truly ischemic #SCA2018EchoWeek
Tissue doppler can be recorded by standard doppler if you eliminate the low pass filter and turn down the scale to ~0.2 m/s #SCA2018EchoWeek
No-one knows anything about RV diastolic dysfunction. Next frontier, or not interesting? #SCA2018EchoWeek
Tricuspid regurg jet peak velocity is NOT TR severity, but RV/RA pressure difference, and therefore an expression of RV systolic pressure #SCA2018EchoWeek
TAPSE validated for TTE, slightly different movement and angle in TEE. TAPSE with speckle tracking can be set to measure between TAPSE and RV apex. #SCA2018EchoWeek
RV has low afterload, so flow starts from the start of contraction (no isovolumetric contraction like LV) and continues to push blood throughout the systole = longer systolic flow than LV (that needs to overcome pressure in aorta first) #SCA2018EchoWeek
Diastolic dysfunction is always present in systolic dysfunction, as normal diastole is dependent on the energy (spring coil) created and stored through systole. #SCA2018EchoWeek
E/e' > 13 also means high LA pressures #SCA2018EchoWeek
In TEE you foreshorten the LV and can't see the true apex. #SCA2018EchoWeek
