Diagnosis of Pulmonary Hypertension Using Cardiac Magnetic Resonance Images

In this study, study team aim to i) evaluate the accuracy of 3D IVS curvedness for prediction of RV systolic pressure (RVSP), mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) with RHC; ii) evaluate the usefulness of 3D IVS curvedness for predicting the response to vasodilator challenge with RHC, in patients clinically suspected or known to have primary PH.
