Congenital Heart Disease Chd Video
Adult Congenital Heart Disease Pregnancy and CHDA congenital heart defect CHDalso known as a congenital heart anomaly and congenital heart diseaseis a defect in the structure of the heart or great vessels that is present at birth. The cause of a congenital heart defect is often unknown. Congenital heart defects are partly preventable Hart rubella vaccinationthe adding of iodine to salt, and the adding of folic acid to certain food products. Congenital heart defects are the Congenital Heart Disease Chd common birth defect.
Signs and symptoms are related to type and severity of the heart defect. Symptoms frequently present early in life, but it is possible for some CHDs to go undetected throughout life.
Congenital heart defects cause abnormal heart structure resulting in production of certain sounds called heart murmur. These can sometimes be detected by auscultation ; however, not all heart murmurs are caused by congenital heart defects.
What Are Congenital Heart Defects?
Congenital heart defects are associated with an increased incidence of seven other specific medical conditions, together being called the VACTERL association : [ citation needed ]. Hert common defects in the association are truncus arteriosus and transposition of the great arteries. The cause of congenital heart disease may be genetic, environmental, or a combination of both. Genetic mutations, often sporadic, represent the largest known cause of congenital heart defects. The genes regulating the complex developmental sequence have Congenital Heart Disease Chd been partly elucidated. Some genes are associated with specific defects. A number of genes have been associated with cardiac manifestations.
Mutations of all these proteins are associated with both atrial and ventricular septal defects; In addition, NKX is associated with defects in the electrical conduction of the heart and TBX5 is related to the Holt-Oram syndrome which includes electrical conduction defects and abnormalities of the upper limb.
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 heart 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 Congenital Heart Disease Chd involved in the development of the ventricular wall and the connection of the outflow tract to the great vessels.
How are Congenital Heart Defects Detected?
For another Congenital Heart Disease Chd of the gene Conbenitalmutations 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. Known environmental factors include certain infections during pregnancy such as rubelladrugs alcoholhydantoinlithium and thalidomide and maternal illness diabetes mellitusphenylketonuriaand systemic lupus erythematosus. Being overweight or obese increases the risk of congenital heart disease.

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 Conyenital, 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.
At day 22, the circulatory system is bilaterally Dusease with paired vessels on each side and the heart consisting of a simple tube located in the midline of the body layout. 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. On day 28, areas of tissue in the heart tube begin to expand inwards; after about two weeks, these expansions, the membranous " septum primum " and the muscular Congenital Heart Disease Chd endocardial cushions ", fuse Congenital Heart Disease Chd form the four chambers of the article source
