This study in patients with pulmonary hypertension (PH) assesses the relation of RAC, transverse and longitudinal RV measurements with RVEF as calculated from multislice cine MRI. RVEF is better reflected by RAC than longitudinal wall motion or transverse wall motion in patients with PH. We postulate this is because RAC assesses RV function in both the transverse and longitudinal directions. Transverse RV function showed a similar correlation to longitudinal function for predicting RVEF in our mixed cohort of PH patients
