Models of distribution of fetal blood flow as percentage of combined ventricular output by anatomical and physiological group, based on PC CMR measurements. LA-left atrium; RA-right atrium; LV-left ventricle; RV-right ventricle; CVO-combined ventricular output; MPA-main pulmonary artery; AAo-ascending aorta; SVC-superior vena cava; PBF-pulmonary blood flow; FO-foramen ovale; DA-ductus arteriosus; DAo-descending aorta; UA-umbilical artery; UV-umbilical vein; CA-coronary artery; CS-coronary sinus; AS/CoA-aortic stenosis and/or aortic coarctation; PVO-pulmonary vein obstruction; HLHS-hypoplastic left heart syndrome; UAS-unrestrictive atrial septum; I/HRAS-intact or highly restrictive atrial septum.
