This study explores the relationship between in vivo 4D flow cardiovascular magnetic resonance (CMR) derived blood flow energetics in the total cavopulmonary connection (TCPC), exercise capacity and CMR-derived liver fibrosis/congestion. After the study, it is concluded that 4D flow CMR is promising as a non-invasive screening tool for identification of patients with adverse TCPC flow efficiency.
