I have no words to express my gratitude to you. Please upload more videos. You are such an amazing teacher

[@mirhansyahperdana7113]

I thought ffr and ifr were that simple. After watching this video, i realize i know nothing. Thank u sir 🙏🙏

[@areenal-taie6836]

Thank you very much Dr Hanna
Excellent teaching as usual
Please continue to teach us more tricks in interventional cardiology

[@nouraldeenmanasrah3501]

Thank you for the amazing lecture

[@pavanprasad2529]

Sincere thanks to Dr Hanna . Explained very well. Being an engineer i am able to understand these topics very clearly.

[@Mohamed-cz7kc]

we all thank god that sent you sir to help us to master intervention cardiology graduated from your school .

[@Taleb1160]

Thank you immensely Dr Hanna .. the session is most valuable and brilliantly explained.

[@Nikesnipe]

The Video we were all waiting for Thank u so much

[@jn9003]

very useful and instructive , your hard work is not in vain sir

[@drvivekmaheshagrawal]

Beautifully explained 👍

Big salute 🫡🫡🫡

[@aroojzahid3138]

Simply the best lecture

[@shamsrehan8942]

Amazing lecture sir as usual , am so thankfull to u sir

[@mohamedemara6853]

Wonderful presentation, sir

[@gyanpapisen7806]

Why is it so that if FFR is 0.8, the pressure waveform of the distal coronary vessel loses the dicrotic notch and gets ventricularised ? I didn't get it...

[@usmanmustafa3550]

Great great talk.

[@Mohamed-cz7kc]

thank you sir ❤

[@Shiv_Gupta]

Perfect knowledge sharing. Thanks for uploading here. Do you have more details on Impella working or can share a link?

[@eliashanna8248]

Thank you. If your question is regarding the effect of Impella on FFR, you may review my Impella talk czcams.com/video/FF9C5VxIJZM/video.html, minute 22:37. I cite 2 references, especially an important one that showed that Impella increases distal coronary pressure even past a significant stenosis (unlike IABP).
