Cardiac MR provides valuable information of the cardiac structure-function, but it is underutilized in the diagnosis and monitoring patients with pulmonary hypertension. In this study, we performed a comprehensive evaluation of the left ventricle in patients with pre-capillary pulmonary hypertension including feature-tracking strain, T1 mapping, and tissue phase mapping. We also evaluated the association of these CMR-derived quantitative measures with right heart catheterization derived pressure measurements.
