Velocity measurements by MRI are compared to echocardiography. Pulmonary capillary wedge pressure (PCWP) from MRI is compared to echocardiography (echo) and RHC measurements. Intraobserver and interobserver reliability of the MRI measurements is assessed by the intraclass correlation coefficient (ICC). ICC values significantly different from zero (p<0.05) are denoted by *.
