A hemodynamic journey: HFpEF, constriction, afterload. What is afterload? Elias Hanna

**May review my 2 prior videos of constriction vs restriction vs RV failure
0:00 HFpEF mimickers.
02:43 Abnormal septal motion: 3 simple diagnoses (+4th one 11:55). More fine-tuned analysis of septal motion (3:56)
09:26 3 major echo features for diagnosing constrictive pericarditis.
14:05 Invasive hemodynamic features of constrictive pericarditis. Very poor specificity of static right heart findings.
18:32 Technical tips in analyzing RV/LV discordance on real-life tracings + 4 tips to improve the yield.
30:32 Transient inflammatory constrictive pericarditis ~ effusive constrictive pericarditis (+ 07:40). Value of MRI
34:10 Why biventricular failure post-pericardiectomy
35:10 Define ventricular afterload and LV transmural pressure- Wall stress
42:30 Afterload is not systemic vascular resistance

Few notes:
-On the LV-RV recording, there is no need to use a respirometer to identify inspiration vs expiration. Just pick the beats based on the depth of the diastolic dips, as explained
-Post-PVC discordance is analyzed regardless of the respiratory phase. For this analysis, there is no need to look for specific respiratory phases or define specific respiratory beats. As explained, post-PVC behavior is not always discordant in constriction, but when discordant, it further supports the diagnosis of constriction
-For MRI and CT: pericardial thickening is defined as pericardial thickness 3 mm or more
