Right ventricular (RV) function has a significant
impact on the prognosis of chronic thromboembolic
pulmonary hypertension (CTEPH), as it does with
other forms of pulmonary arterial hypertension (PH). In this study,
we demonstrated that feature tracking imaging (FTI) is fast, simple, and has
potential for clinical use for assessing RV strain in CTEPH. The global longitudinal strain
(GLS) showed better correlation with the RV ejection fraction
(RVEF) and mean pulmonary artery pressure (mPAP). FTI-derived strain measurement might offer a modality for good
detection of RV dysfunction and repeatable monitoring after
therapeutic intervention.
