Congenital heart disease is usually an abnormal heart condition that is present in infants at birth and is referred to as congenital heart disease. The most common types of congenital heart disease include atrial septal defect, interventricular fusion defect, patent ductus arteriosus, tetralogy of Fallot, tetralogy of Fallot, and so on. The pathogenesis of congenital heart disease is complex, and there is no definite answer so far. It can only be said to be the result of the complex interaction of genetic and environmental factors. Congenital heart disease is generally not a hereditary disease, but some families have more than one person with congenital heart disease, or in the blood relatives (such as uncles, uncles, aunts, uncles, cousins). Known risk factors for CHD include: viral infections in early pregnancy, altitude, nutritional deficiencies during pregnancy, lesions of the amniotic membrane, fetal compression, early miscarriage, diabetes mellitus, hypercalcemia, radiation and cytotoxic drugs in early pregnancy, and the age of the mother. After the birth of the child, parents should carefully observe the child for the following symptoms, if so, the child is more likely to have congenital heart disease. A part of the children with CHD will be out of breath after breastfeeding, not cry loudly, cry short, chest heaving; panic and shortness of breath after activities; easy to get pneumonia, often have fever and need to be transfused or hospitalized. If parents find that their children have these conditions, they should take their children to the hospital as soon as possible so that an early diagnosis can be made. In addition, many children with CHD do not have symptoms and their problems are detected during routine heart examinations. Children with CHD often have a heart murmur, so most babies born in a regular hospital can be detected after initial screening by an obstetrician. Pediatric coronary heart disease treatment should follow the “three early” principle 1, early detection: parents should understand some of the onset of coronary heart disease signals, carefully observe the child, when the child appears abnormal performance, to do early detection; 2, early diagnosis: suspected that the child suffers from coronary heart disease, should be timely to the regular hospital for treatment. In general, doctors will diagnose through routine auscultation, electrocardiogram, chest X-ray, echocardiography, cardiac catheterization and cardiovascular angiography and other tests. Clinically, due to the different conditions of the patients, the examination methods are not set in stone, and the doctors will use their discretion; 3. Early treatment: Among the three types of pediatric congenital heart diseases, atrial septal defect, ventricular septal defect, and arterial ductus arteriosus, a certain percentage of the children usually have the possibility of self-healing, and the doctors may suggest observing them for a certain period of time. Other than that, most of the congenital heart diseases need to be corrected by surgical methods. Early treatment is the key to cure children with congenital heart diseases. Doctor’s tip: Pediatric congenital heart disease is a common disease that seriously jeopardizes children’s physical and mental health. If left untreated, it can have a great impact on a child’s life and learning, and even threaten his or her life. Due to the different conditions of patients, as well as the many types of congenital heart disease, the symptoms and examination methods of children are not set in stone, and the means and timing of treatment should be considered according to the specific conditions of patients. However, early detection, early diagnosis and early treatment are the key to improving the treatment and saving the life of the child.
