Pulmonary hypertension in interstitial lung disease: Limitations of echocardiography compared to cardiac catheterization

Abstract

In patients with ILD and suspected PH, currently recommended ESC/ERS TR velocity screening thresholds were associated with a high positive predictive value (86%) for confirming PH, but were of limited value in excluding PH, with 40% of patients misclassified as low probability when PH was confirmed at subsequent RHC.
