Can congenital heart disease be inherited?
Congenital heart disease is generally not inherited. Innate is not equal to heredity. The so-called hereditary congenital heart disease is mostly related to chromosome diseases. Such patients often suffer from diseases other than heart disease, such as immunodeficiency and mental retardation.
How long can congenital heart disease live?
For congenital heart disease, the most important thing is early and timely treatment. Children with congenital heart disease may grow and develop like normal children if they receive formal treatment before the age of 5. Early treatment will have a higher chance of cure. If you choose not to treat, the final result may be death from heart failure.
If there are symptoms of heart failure, the possibility of cure is relatively low, and some complex congenital heart diseases are also difficult to cure, such as transposition of great vessels, single ventricular malformation, persistent arterial trunk and so on. The operative mortality was above 10%. If the treatment is not timely, surgery can be performed, and there is no possibility of cure.
With the development of medical technology, patients with common congenital heart disease can be cured by heart transplantation or corrective surgery, and most patients can return to normal life after treatment. Therefore, for congenital heart disease, we don't want to live long, but we should face it positively and treat it in time.
How to prevent congenital heart disease
At present, more than 85% of congenital heart diseases may be caused by the interaction of fetal environmental factors and genetic factors. Therefore, strengthening pregnant women's health care, especially folic acid supplementation in the first trimester, avoiding all kinds of infections, avoiding taking drugs that are unfavorable to the fetus and maintaining a healthy lifestyle are of great significance to prevent neonatal congenital heart disease.
What causes congenital heart disease?
Congenital heart disease is caused by problems in the process of heart development, and any factors that interfere with heart development will lead to diseases. The most common pathogenic factors are rubella, influenza and coxsackie virus. Pregnant women lack folic acid; Taking drugs during pregnancy, such as anti-tumor or antiepileptic drugs; Pregnant women suffer from diabetes and so on. In addition, premature delivery is also one of the important causes of neonatal congenital heart disease.
Common types of congenital heart disease are atrial septal defect and ventricular septal defect.
Atrial septal defect and ventricular septal defect will lead to blood circulation between atrium and ventricle. Due to left ventricular hypertension, blood flows to the right heart, which significantly increases the workload of the right heart. In the long run, it will lead to right heart failure. And blood flows to the lungs through the right heart, resulting in excessive lung blood and increasing the chance of respiratory tract infection.
Patent ductus arteriosus
During the embryonic period, the fetal lung pressure is too high, and the blood from the pulmonary artery cannot enter the lungs, so it can only enter the aorta through the arterial catheter. After the baby was born, the lung pressure decreased significantly. If the arterial catheter is not closed, the direction of blood flow inside will be reversed. Blood will flow from the hypertensive aorta into the pulmonary artery, enter the left heart through the lung, increase the workload of the left heart, and gradually develop into left heart failure, pulmonary hypertension and even right heart failure.
Tetralogy of Fallot
Tetralogy of Fallot is a serious cardiac structural abnormality, which is manifested as: when the baby is active or crying, his face is blue, and he often likes to squat suddenly during the activity to alleviate the symptoms of hypoxia. At present, this kind of congenital heart disease is difficult to cure.
