Pulmonary Hypertension Classification (2022 ESC)
| mPAP | Classification |
|---|
| ≤20 mmHg | Normal |
| 21–24 mmHg | Borderline elevated |
| ≥25 mmHg | Pulmonary hypertension |
Echo: RVSP = 4 × TRV² + RAP
mPAP ≈ 0.61 × RVSP + 2
Cath: mPAP = (sPAP + 2 × dPAP) / 3
Clinical Notes:
• Echo estimation of PAP has significant limitations — right heart catheterization remains the gold standard
• PH confirmed only by RHC: mPAP >20 mmHg at rest
• Pre-capillary PH (Group 1, 3, 4, 5): PCWP ≤15 + PVR ≥2 WU
• Post-capillary PH (Group 2): PCWP >15 mmHg
