The congenital heart disease

Molecular pathways[ edit ] The notch signaling pathwaya regulatory mechanism for cell growth and differentiation, plays broad roles in several aspects of cardiac development. Notch elements are involved in determination of the right and left sides of the body plan, so the directional folding of the The congenital heart disease tube can be impacted.

Notch signaling is involved early in the formation of the endocardial cushions and continues to be active as the develop into the septa and valves. It is also involved in the development of the ventricular wall and the connection of the outflow tract to the great vessels. For another member of the gene familymutations in the Notch1 gene are associated with bicuspid aortic valvea valve with two leaflets instead of three.

Notch1 is also associated with calcification of the aortic valve, the third most common cause of heart disease in adults. It is known that the risk for congenital heart defects is higher when there is a close relative with one. Heart development There is a complex sequence of events that result in a well formed heart at birth and disruption of any portion may result in a defect.

On day 19 of development, a pair of vascular elements, the "endocardial tubes", form. The tubes fuse when cells between then undergo programmed death and cells from the first heart field migrate to the tube, and form a ring of heart cells myocytes around it by day On day 22, the heart begins to beat and by day 24, blood is circulating.

The portions that will become the atria and will be located closest to the head are the most distant from the head. From days 23 through 28, the heart tube folds and twists, with the future ventricles moving left of center the ultimate location of the heart and the atria moving towards the head.

A failure to fuse properly will result in a defect that may allow blood to leak between chambers. After this happens, cells which have migrated from the neural crest begin to divide the bulbus cordisthe main outflow tract is divided in two by the growth a spiraling septum, becoming the great vessels—the ascending segment of the aorta and the pulmonary trunk.

If the separation is incomplete, the result is a "persistent truncus arteriosis". The vessels may be reversed " transposition of the great vessels ". The two halves of the split tract must migrate into the correct positions over the appropriate ventricles.

A failure may result in some blood flowing into the wrong vessel e. The four-chambered heart and the great vessels have features required for fetal growth.

The lungs are unexpanded and cannot accommodate the full circulatory volume. Two structures exist to shunt blood flow away from the lungs. Cells in part of the septum primum die creating a hole while muscle cells, the " septum secundum ", grow along the right atrial side the septum primum, except for one region, leaving a gap through which blood can pass from the right artium to the left atrium, the foramen ovale.

A small vessel, the ductus arteriosus allows blood from the pulmonary artery to pass to the aorta. The foramen ovale stays open because of the flow of blood from the right atrium to the left atrium. As the lungs expand, blood flows easily through the lungs and the membranous portion of the foramen ovale the septum primum flops over the muscular portion the septum secundum.

If the closure is incomplete, the result is a patent foramen ovale.Congenital heart disease, also known as congenital heart defect, is a heart abnormality present at birth.

The congenital heart disease

is a national organization that provides reliable information, advocacy, support services, financial assistance and resources to families of children with congenital heart defects and acquired heart disease, and adults with congenital heart defects.

The terms “congenital heart defect” and “congenital heart disease” are often used to mean the same thing, but “defect” is more accurate. This kind of heart ailment is a defect or abnormality, not a disease.
