High-risk echocardiographic features predict mortality in pulmonary arterial hypertension

Estimated right atrial pressure> 15, tricuspid regurgitation ≥ moderate, and presence of pericardial effusion are high-risk echocardiographic features in PAH. When seen in combination, these features greatly increase risk of mortality in PAH and may lead to more timely enhanced therapy for patients identified as having an increased risk for death.
