The case of prenatal ultrasound diagnosis of complete transposition of the great arteries and dextrocardia
in the fetus with left juxtaposition of the atrial appendages and subpulmonary ventricular septal defect in
the third trimester is presented. The postnatal echocardiography confirmed the prenatal diagnosis. At 2 months
of life, first surgical intervention under extracorporeal circulation was performed: the arterial switch operation
and narrowing of the dilated pulmonary artery root, closure of patent foramen ovale, ligation of patent ductus
arteriosus. At the age of 8 months, the child underwent a second operation: closure of ventricular septal defect
with the transventricular approach and plastic surgery of the pulmonary artery. After an operation third-degree
atrioventricular block (bradyarrhythmias) has occurred and 2 weeks later patient's health improvement was
achieved, and he underwent implantation of a single-chamber pacemaker. Currently, the child is 2 years old,
physical and mental development corresponds to age and he remains under the supervision of specialists.
