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
