Precision in PH-ILD: Applying the 2025 ASE Guidelines for Right Heart Assessment

Recorded: March 25, 2026

Pulmonary hypertension associated with interstitial lung disease (PH-ILD) presents a unique diagnostic challenge that demands precise ultrasound acquisition and interdisciplinary collaboration. This session bridges the gap between pulmonology and sonography by applying the 2025 American Society of Echocardiography (ASE) Guidelines for the Assessment of the Right Heart, moving beyond simple pressure estimation to a comprehensive evaluation of right ventricular (RV) adaptation and remodeling.

Learn how to navigate the new hemodynamic probability thresholds, specifically the significance of a tricuspid regurgitation velocity ≥ 2.8 m/s when combined with secondary signs like right atrium dilation (> 18 cm²) and abnormal septal morphology. Expert faculty will clarify the complementary roles of the care team: what sonographers must capture (including the mandatory RV-focused apical view, RV outflow tract midsystolic notching, and RV-pulmonary arterial coupling indices like the tricuspid annular plane systolic excursion/pulmonary artery systolic pressure ratio) and what pulmonologists must explicitly request to differentiate precapillary PH-ILD from postcapillary left heart disease. Designed for pulmonologists, cardiologists, and sonographers, this webinar emphasizes workflow integration to improve diagnostic accuracy and determine when invasive right heart catheterization is warranted.
