Abstract：ObjectiveTo investigate the prenatal ultrasonic diagnostic features of tetralogy of Fallot（TOF） in early pregnancy. MethodsThe prenatal ultrasound data of a case of 14-week-old fetus with TOF, who was confirmed by pathological anatomy in the Ultrasound Department of Laizhou Maternity and Child Healthcare Hospital on September 22,2019 were retrospectively analyzed, and literatures were reviewed. ResultsThe prenatal echocardiography of TOF showed abnormal cardiac axis and tricuspid regurgitation in four chamber view. Perimembranous ventricular septal defect, widened aorta straddling the interventricular septum were showed in left ventricular outflow tract. Color Doppler flow imaging showed the color “y” sign, which was formed by left ventricular blood flow and right ventricular blood flow through ventricular septal which entered the aortic in systole together. Narrowed pulmonary artery was showed in right ventricular outflow tract. Pathological anatomy confirmed the diagnosis of TOF. ConclusionsTOF is a common conotruncal defect. Ultrasonic examination is noninvasive and simple, which can provide imaging evidence for prenatal diagnosis of TOF.
