didactically excellent videos also the books, I also read the recommended papers . The best learning platform in cardiology in my opinion. I’m a real big fan.❤
No, I misspoke, as I indicated in one of the comments below. From 05:28 to 05:40, I am referring to the pulmonary systolic and pulmonary diastolic pressures, not aortic pressures. The picture I am referring to indicates that I am referring to the PA not aorta. But I will also add a time stamp pointing to that. Thank you! That was the first video I ever uploaded, I did not use to do any editing. But now I edit my videos more carefully.
Dr.Hanna, do we use the end-expiratory LVEDP as the best estimates of LV filling pressure measurements like in wedge pressure tracing? Or just use the computer-generated LVEDP which is the average EDP throughout respiratory cycle? Thank you in advance sir
For all pressures, including LVEDP, the most accurate measurement is obtained when the respiratory pressure is 0 mmHg: this avoids a direct effect of the respiratory pressure on the catheter tip. Unless the patient actively exhales, corresponds to end‐expiration (highest pressure points in spontaneous breathing). But in patients breathing deeply (e.g., sedated morbidly obese), expiratory pressure is positive; the negative inspiratory and positive expiratory pressures cancel each other out and averaging vascular pressures over several respiratory cycles is preferred. This also applies to when you measure exercise hemodynamics. The average will be closer to expiration (longer) than inspiration (~2/3 of exp +1/3 of insp).
Thank you so much for the very kind words! I am so glad you like my book. It is very time consuming, but hopefully I will keep updating and publishing newer editions, as long physicians like you continue to read :).
@eliashanna8248 yes please .. doctors here they always thank me for giving them this book actually I do not read any other book accept yours it's really great .. can you please tell me what is the last edition because I have only 2022 !

Which book are you referring to?
Dr HANNA, My utmost respect for sharing your knowledge.
Absolutely wonderful lecture. Perfect accompaniment after reading the book. Thank you so much!
Excellent.. Thank you Hanna
Amazing as usual thank you sir. In 5:30 I think you mean pulmonary NOT aortic?
Yes, you are correct. I misspoke. Thank you for pointing it out.
Very nice presentation
At 5:30 min you said Mean PCWP is equal to Aortic Diastolic pressure. Is it true??

Dr. Hanna is it possible the aortic pressure to be advanced than LV pressure during ejection phase of normal cardiac cycle? Tnx beforehand!!!
Thanks for that informative lecture
Excellent stuff!
Hemodynamics masterclass sir.... excellent info..tx
Thank You sir...it was too difficult But will try to watch it twice or maybe thrice to understand it properly
excellen. Thank you
thanks greatly
Perfect
thanks a lot
His book is my book of cardiology is the best is like bible of cardiology
