Compliance (C), mean pulmonary arterial pressure (mPAP), pulmonary vascular resistance (PVR), pulmonary capillary wedge pressure (PCWP), systolic pulmonary arterial pressure (sPAP), diastolic pulmonary arterial pressure (dPAP), measured by right heart catheterization (RHC) and MRI. Intraobserver and interobserver reliability is assessed by the intraclass correlation coefficient (ICC). ICC values significantly different from zero (p<0.05) are denoted by *.
