CHD: congenital heart defect; GA: gestational age; FCI: fetal cardiac intervention; TV: tricuspid valve; PV: pulmonary valve; PA: pulmonary artery; RV/LV ratio: ratio between the length of both ventricles, measured in early systole in the four-chamber view; AD: arterial duct; DV: ductus venosus; TR: tricuspid regurgitation (it was considered severe—Sv—if it was of holosystolic, reaching the wall of the right atrium. Otherwise, it was considered not severe—Not Sv); Rv: reversed; At: antegrade; Mx: mixed; Ab: absent.
