Pulmonary hypertension hemodynamics: misunderstood concepts, tips and tricks- Elias Hanna, Univ Iowa

0:00 Tip 1: Single most important measurement in PH The 3 hemodynamic categories of PH PVR equation
09:10 Tip 2: 2 caveats of PCWP measurement in PH
21:01 Tip 3: How does PA pressure change with vasodilator therapy. Is it necessary for PA pressure to decline in order to consider the patient responsive?
22:42 Tip 4: What parameters are used to assess treatment response?
25:27 Tip 5: Value of pulmonary vasoreactivity testing
29:07 Tips 6 and 7: What causes hypoxemia in PAH? Is right-to-left shunt usually a problem in PAH, or is it rather compensatory mechanism?
37:30 Tip 8: Can you have postcapillary PH with normal PCWP? When to suspect such an instance? (39:20) Types of hemodynamic stress testing of the left heart in the cath lab (40:41)
43:32 LVEDP vs PCWP (also review my other talk: Hemodynamic lecture 1)
45:50 Tip 9: Can patients with combined pre- and post-capillary PH be treated with pulmonary vasodilators?
50:20 Tip 10 Postcapillary PH with small-to-moderate ASD. Should it be closed? Roles of small left-right and right-left shunts in PAH (56:04)
56:41 Tip 11: True PAH from large left-to-right shunt: 4 stages (reversible to irreversible to Eisenmenger)
1:00:57 Tip 12: High flow state as aggravating factor of PH
1:03:20 Tip 13: Thermodilution CO remains accurate in severe TR

Thank you dr hanna great job

Thanks greatlY

Wonderful Explanation, thank you Dr. Hanna

Professor, thank you so much once again for a great lesson. I have a practical doubt. In terms of time, How long does it take for a POSTCAPILLARY PH to became a Hybrid one (CPC-PH) due to remodelling? And is it only a matter of time or are there any other contributing factors like pressure values, etc. Greatings from Brazil🙏🏼

Medical Is it categorised under Group I ? Group II ?? The ceiling for group I and group II is for clerical jobs ? It is presumably group IV ....... TRB has a ceiling above 50,000 but medical student interns have reached this in the 1990s ........ More private clinics ............. P Leela

another lecture for acute pulmonary embolism

[@remonsobhi6231]

we want a lecture about pulmonary embolism

[@theeeeeb21]

Thank you, its ok if you share the slides with us ?

[@m.s3815]

Dear Dr Hanna, can we have a sudden drop in severe pulmonary hypertension? For example from 80mmhg to 40-45?

[@eliashanna8248]

It is not common but it can happen for 2 reasons: (1) those who are very responsive to vasodilators, such as the extreme of those who fulfill the official definition of "vasodilator responsive" (drop in mean PA of >10 to
