patent ductus arteriosus.

It's a wonderful educational video, but I have to mention a few things in order to clear it out.
1. IVSd, IVSs measurements seem wrong. You measured IVSs

tanks for greatest educational and comprehensive algoritm , amasing🎉

[@Philiastorgos]

Dr Chaudhari, thank you so much for uploading these videos. They are very useful in learning how to interpret echo images. I've learned a lot more from your videos than I do from most other echo videos.

[@ankurmontu]

Thank you very much

[@aymantantawy1475]

Very good case and presentation.
Qp/Qs calculations should be revised.
Usually we suspect PDA if we found dilated LV not right side of heart as stated in conclusion. (volume overload on LV)

Drokhotin: We don,t know if Qp/Qs is correct.... But I will remember in the PDA the sistemic blood flow must be calculated from tricuspid valve or the right ventricular outflow and pulmonares blood flow is calculated from the mitral valve or aortic valve sites, contrary to what is usually done.... And erros exista in formula: VTI is measured in cm, not máximal velocity....

[@marwaelattar6471]

Thank you so much, clear illustration of such case. it helped me a lot .. appreciated

[@drsarah5751]

Very informative video thanks dr Ankur

[@zehraahmed8018]

Thank you Dr you made echocardiogram easy for me

[@ankurmontu]

Thanks

[@ArtemyOkhotinDr]

Qp:Qs calculation is wrong. You calculate Qp instead of Qs and vice versa. But other errors allowed you to obtain more-or-less (more less, than more) plausible result.
In PDA flow across LVOT represents Qs and flow across RVOT represents Qp.
VTI is measured my tracing PW spectrum, you take max. velocity. In RVOT you measure max velocity using CW doppler instead of VTI. You measured high flow turbulent flow through pulmonary valve. And the last, but not least, LVOT diameter is undermeasured.

[@hellib2852]

In RVOT, is it measured using CW? I thought it's PW..?

[@drgaganvelayudhan1733]

VTI is best measured with PW. Esp in pulmonary side CW may pick up part of the PDA flow.

[@user-kd4gl7dz4u]

it is really so good to discuss the work atcheived..
thanks to all of you great people

[@bkrawat007]

AV Vmax 1.65m/s
AV maxPG 10.88mmhg
TR Vmax 2.59m/s
TR maxPG 26.78 mmHg
PDA size 6mm
Is it significant ?
And what is the best way of T/t?

very good. thank a lot

[@dr.khaled5860]

Wt about
smallest PDA diameter/diamrter of ostium of left PA diameter
If >0.5...small
0.5-1....moderate
>1....large PDA
Wt also about % of retrograde diastolic flow to antegradr aortic flow in desc. aorta by CW
If 50% ...large
assessment of LV ,LA to assess significane of shunt ...
By PW at the pulmonary end of the shunt
If velocity >1.5 m/s.... non significant PDA
IF VELOCITY

[@richardbailey8019]

Also when you add color and you drop the frame rate below 20 Hz the color is no longer corresponding with the heart beat. (Tall skinny boxes)

[@carolinamoreira7766]

That's great presentation . Thanks doctor.

[@ankurmontu]

Thank you

[@nagisettiprasanth8123]

it's does'nt need surgical closure , device closure is pretty good...

[@kamalmalviya4721]

beautiful presentation,coceptualy more beautiful.

[@ankurmontu]

Thank you very much.

[@atlasofcongenitalandstruct901]

Thanks but some revision for measurement of Qp/Qs and the pulmonary end of the PDA is needed

[@kashifalikhan2535]

👍

[@abdullahalhasan2591]

It's so nice and easy understanding.
Thanks a lot.

[@ankurmontu]

Thanks

[@muhammadjamil-lh9qy]

Great presentation

[@blagdongj]

With image quality that good, those measurements should have been flawless

[@ankurmontu]

Thank you so much sir.

[@DrRifaatAldaghir]

very nice and perfect

[@ankurmontu]

thanks

[@MarwaMarwa-uq9lg]

Pda is supposed to cause left atrial and left centricular enkargment. Could the right sided enlargement be because if anther cause?

[@DrMohammadHamedHelal]

In PDA left side will be Qp
and right side will be Qs

[@suryaganapathi488]

Superb

[@ankurmontu]

Thanks
