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
