Prenatal 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

Abstract

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.
