What is congenital heart disease?
Congenital heart diseases are heart defects occur even before birth. They are quite common: at nearly 1% of newborn children.
Sometimes it is immediately apparent that something is wrong with the heart of the baby. The baby looks very blue at birth and have breathing problems. The doctor listens to the heart and hearing disorders.
But it can also prevent heart disease for a long time unnoticed. Someone then comes adulthood until later. Often there are complaints for years, such as:
- tiredness;
- less stamina;
- shortness of breath;
- often fainting;
- often respiratory tract infections (primarily bronchitis and pneumonia);
- sometimes bluish lips and nails.
People with congenital heart disease are being treated by a cardiologist. The cardiologist speaks to how often checks are necessary. A simple congenital heart defect is usually once every five years. In a complicated heart defect requires an annual inspection.
Forms of congenital heart disease
There are different types of congenital heart disease. Often the heart is not 'built' good. There are then abnormalities in the structure of the heart and / or the large vessels. Examples are:
- atrial septal defect (hole in the wall between the atria);
- ventricular septal defect (hole in the wall between the rooms);
- ductus arteriosus (blood vessel that does not close);
- tetralogy of Fallot (wrongly constructed wall between the lung and aorta);
- abnormalities of the heart valves;
- abnormalities of the heart chambers;
- wrong landscaped arteries or veins.
A final group of heart disorders that can occur already before birth, deviations in the electrical control system of the heart. These abnormalities can cause arrhythmias. An example is the Wolff-Parkinson-White syndrome.
