Survival of patients with pulmonary arterial hypertension (PAH) is closely related to right ventricular (RV) function. This study aims to introduce a fast global longitudinal strain (GLS) measurement for RV function assessment by automatically tracking the distance variation between tricuspid annular insertion points and the RV apical epicardium. The intra- and inter-observer variation of coefficients range from 3.9% to 5.7% with processing time averaging 32 ± 8 seconds per subject. Results demonstrate that lower fast GLS measurements are closely related to impaired RV function and higher risks in PAH.
