Aortic coarctation in newborns. Modern state of the problem

Abstract

Coarctation is found in 8% of all congenital heart diseases. Clinical course of this defect varies from cardiogenic shock while closing an arterial duct in newborns to an asymptomatic hypertonia. Infants with this pathology are often in a critical condition requiring an urgent intervention. Sometimes atypical clinical course of this defect causes difficulties for a cardiologist to make an exact diagnosis. There is no doubt in indications for surgery in cases with this anomaly. From the beginning of an era of E1 prostaglandin patients with ductal-dependent blood circulation began referring to specialized clinic in a stable state that affected significant decrease in a hospital mortality. However in this problem there is a number of topical issues. They are surgical methods of correction, their longterm results, recurrence rates, methods of correction for the accompanying arch hypoplasia, correction though one or two accesses in a case with arch obstruction combined with other intracardiac anomalies. In what terms it is necessary to carry out re-interventions and a role of balloon dilatation at recoarctation. The review sets the task to generalize the accumulated knowledge and to present treatment results of the most succeeded researchers on this problem.
