Congenital heart abnormalities

You may be very anxious to know your child has a congenital heart abnormalities Actually, do not worry too much. Congenital heart abnormalities is fairly common thing to happen and now-thanks to advances in science and medical technology, many of which can be cured with surgery, catheterization and drugs.
Congenital heart defects are very diverse kinds. Here are some of them

Ventracular Septal Defect / VSD
VSD is a hole in the heart abnormalities septum between the ventricles which cause the leakage of blood flow on the left and right chambers of the heart. These leaks make the most oxygen-rich blood back to the lungs so that the blocking of low blood oxygen enters the lungs. When a small hole, VSD does not provide significant problems.
VSD is a congenital heart defect that occurs most frequently (30% of cases). The main symptoms of this disorder is difficulty feeding and growth disorders, shortness of breath and easily tired. Infants with large VSDs fast asleep after about breastfeeding, waking up briefly as hungry, try feeding again but quickly exhausted.

Pulmonary Stenosis / PS
PS is a narrowing of the pulmonary valve which controls the flow of low-oxygen blood from the heart right ventricle to the lungs. With this constriction, the right ventricle must work harder to pump blood so that more and more enlarged (hypertrophy).
PS is the second most common heart defect, occurring in 10% of cases. Many people with ASD are newly diagnosed as adults. If so, the impact may have been very damaging form of lung disease, high stroke risk and low life expectancy.

Atrial Septal Defect / ASD
ASD is a hole between two heart porch. These holes cause the same problem with VSD, which is oxygen-rich blood flows back into the lungs. ASD occurs in 5-7%? cases and occurs more frequently in female infants than male infants.

Tetralogy of Falot / TOF
TOF is a complication of congenital heart defects are typical, and involves four conditions:
Bulkhead hollow chambers of the heart (VSD)
Narrowing of the pulmonary valve (PS)
Right-room enlarged heart (hypertrophy)
The root of the aorta just above the hole VSD
VSD is usually large hole and the blood flow from the right ventricle through the hole into the left ventricle. This occurs because of constraints on the pulmonary valve. After entering the left ventricle, low blood oxygen was pumped into the aorta and flow throughout the body. That's why babies with TOF have skin that is blue from lack of oxygen.
