Coarctation of the aorta is a congenital malformation characterized by the presence of narrowing of the aorta, which can be localized in any part of it. In this publication, we present a clinical case of coarctation of the aorta before and after surgical correction in a newborn. The child was admitted to the cardiosurgical hospital at the age of 6 days. Congenital heart disease of a low category of complexity was diagnosed prenatally. After birth, the condition is satisfactory. After 3 hours, the negative dynamics due to the clinic of respiratory failure. According to echocardiography – hypoplasia of the aortic arch, coarctation of the aorta? Open ductus arteriosus, ventricular septal defect. On the 3rd day of life, a diagnosis of congenital pneumonia was made and the child was transferred to a cardiosurgical hospital. Upon admission to the FCSSH in Astrakhan, the condition was regarded as severe, due to heart and respiratory failure. The child is examined. On echocardiography – Pronounced preductal form of coarctation of the aorta. Hypoplasia of the proximal arch and isthmus. Open ductus arteriosus. Ventricular septal defect. biventricular hypertrophy. Severe dilatation of the right chambers of the heart. Relative hypoplasia of the left ventricle. Tricuspid regurgitation. On the 7th day of life, surgical correction of the defect was performed plasty of the arch and isthmus of the aorta, plasty of the VSD. The early postoperative period proceeded with a clinic of moderate respiratory and heart failure. Against the background of the expansion of the volume of feeding, chylothorax was detected, drainage of the right pleural cavity was prescribed. Enteral feeding has been replaced by parenteral nutrition. The child was extubated on the 4th postoperative day. However, oxygen dependence was noted. The pleural drainage was removed on the 11th day after the operation. On the 12th day, the newborn was transferred from the intensive care unit. Discharged from the hospital on the 20th day after surgical treatment. After 4 months the child was examined in the hospital. The general condition was regarded as satisfactory. This clinical example shows the complexity of prenatal diagnosis of obstructive pathology of the aortic arch and the rapid manifestation of clinical manifestations after birth against the background of an unfavorable combination with a large septal defect.
