Causes and manifestations of congenital heart disease

Causes and manifestations of congenital heart disease: congenital heart disease (TBS) is the child's heart defect (probably at the heart wall or heart valves and major blood vessels) occurred during pregnancy, before when the child is born (usually occurs in the first eight weeks of fetal development).

Listen to the heartbeat for children

 Causes of congenital heart disease:  From the 25th day after fertilization, fetal began forming circulatory system. By week 8, the heart has been created completely. Therefore, the impact from the outside during this time can leave for heart defects.  According to statistics at Tu Du Obstetrics Hospital in Ho Chi Minh City, congenital heart disease, accounting for 0.8% of first pregnancies and 2-6% of pregnancies times 2. If the family has 2 people with congenital heart defects, risks in children will be born as 20-30%.  Up to 50% of cases of congenital heart disease is not determined the cause; the remainder by 2 reasons:  - Genetics: Do mutations or chromosomal mutations during pregnancy, or inherited from previous generations.
- The impact of the environment: Due to pregnancy, maternal disease, infections, viral infections (especially influenza and Rubeole), drinking too much, chemical poisoning and drug treatment or affected of radiation. The signs of congenital heart disease:  In some cases, children with congenital heart disease but not showing symptoms caused by severe defects not only accidentally discovered when a medical examination or examination for another reason.  Some other defects or associated with congenital heart diseases such as Down syndrome, cleft lip - exfoliation dome, lack or excess fingers - toes, head to disabilities, small head ... Best family to take the child away doctor immediately if your child has detected unusual symptoms following:  - Children or cough, recurrent wheezing, abnormal breathing (shortness of breath, chest concave draw inhalation), often with pneumonia.  - Children with pale skin, cold sweats. Children with purple lips, fingers, toes, increased crying, when pushing,  - Children feeding or eating poorly, slowly gaining weight, even without weight gain or weight loss. Retarded children than normal (slow teething, slow rolling from cows).  Congenital heart disease and evidence  Children with disabilities are children with congenital heart when she was just born with abnormalities in the structure of the heart chambers, baffles in the heart, the heart valves, the large blood vessel leaving the heart.  Type of congenital abnormalities of the heart defects are the most common of the two ventricular septum. One type of disability is rarely encountered other ductus arteriosus - a blood vessel in the fetus as trade between the pulmonary artery and the aorta did not close after birth). The other common defects is open atrial septum - the room on the heart, aortic stenosis, pulmonary stenosis.  Other defects are rare but very serious, such as changing the position of the main arteries: the aorta and pulmonary artery swapped with each other; aortic stenosis, and Tetralogy of Fallot consists disability septum, pulmonary artery stenosis, aortic thickening in the wrong place and the right ventricle.
