Blue baby syndrome - Definition

Definition


Blue baby syndrome, also called congenital cyanotic disease, is a disease caused by a congenital heart or vascular defect. This defect causes an abnormal connection between the venous and arterial blood, called a veno-arterial shunt, causing poor oxygenation of the blood during the first hours of life. The name comes from visible symptoms, cyanosis, blue coloration of the skin and mucus membranes. In most cases, tetralogy of Fallot is involved. This disease includes an abnormal connection between the two ventricles, an increase in the size of the right ventricle, a decrease in the diameter of the pulmonary artery, and a malposition of the aortic orifice. Whatever the morphological abnormality, surgery is often necessary in the first weeks of life to enable survival.
