I really want this to be a PDA but I’m not able to convince myself that I see continuous forward flow. What am I missing?

Thanks!

Great, that does make the

Great, that does make the most sense and what I figured, but I thought I had to see non-pulsatile flow through the PA.

Can you explain why my doppler over the pulmonary valve doesn’t show continuous positive flow?

The ones I’ve seen before have a much less pulsatile-appearing flow. Does it vary by patient or is my positioning off? I tried multiple views to get that continuous forward flow but maybe I’m looking at it wrong.

Thanks.

I think its just about being

I think its just about being in the right sweet spot to get a clean holosystolic jet and thats beyond the PV prior to the pulmonary bifurcation for a pda. Peter is on vacation but im sure he can elaborate more eloquently than I when he gets back.

Check out Peter’s page in the about/specialists section as he has beautiful examples of every congenital defect and how to evidence them.

and also search PDA in the archive or any congenital for that matter and this should help

& these are great questions

& these are great questions to ask Peter at our ECHO lecture/lab in October 18-20. We are down to the last 4 spots.

Peter is a fun lecturer and I have yet to see him stumped by anyone:)
