Cardiac output (CO) determination is mandatory for the diagnosis work-up of pulmonary hypertension (PH). It is classically obtained by invasive methods such as indirect Fick (Qfick) and thermodilution (Qthermo) performed during right heart catheterisation (RHC). However, non-contrast, non-invasive and reliable methods may be preferred for clinical routine and post-treatment monitoring of patients. This study compared QFlow derived parameters (stroke volumes and cardiac index/ pulmonary and aortic flow) measured non-invasively in PH patients for internal validation of MRI and for comparison to RHC.
