ESC/ERS guidelines: arbitrary criteria for estimating the presence of pulmonary hypertension (PH) based on tricuspid regurgitation peak velocity and Doppler-calculated systolic pulmonary arterial pressure (Ppa) at rest (assuming a normal right atrial pressure of 5 mmHg) and on additional echocardiographic variables suggestive of PH

CriteriaClass#Level
Echocardiographic diagnosis: PH unlikely
    Tricuspid regurgitation velocity ≤2.8 m·s−1, systolic Ppa ≤36 mmHg and no additional echocardiographic variables suggestive of PHIB
Echocardiographic diagnosis: PH possible
    Tricuspid regurgitation velocity ≤2.8 m·s−1, systolic Ppa ≤36 mmHg, but presence of additional echocardiographic variables suggestive of PHIIaC
    Tricuspid regurgitation velocity 2.9–3.4 m·s−1, systolic Ppa 37–50 mmHg with/without additional echocardiographic variables suggestive of PHIIaC
Echocardiographic diagnosis: PH likely
    Tricuspid regurgitation velocity >3.4 m·s−1, systolic Ppa >50 mmHg, with/without additional echocardiographic variables suggestive of PHIB
    Exercise Doppler echocardiography is not recommended for screening of PHIIIC
