Symptoms of congenital heart disease

summary

Heart disease is not unfamiliar to everyone. Heart disease is a kind of common circulatory system disease. The circulatory system is composed of heart, blood vessel and neurohumoral tissue regulating blood circulation, which is a kind of disease of circulatory system. However, congenital cardiovascular disease is the most common type of congenital malformation. With the development of cardiac diagnostic methods and surgical treatment technology, the vast majority of congenital cardiovascular diseases can be diagnosed and corrected, and the prognosis has improved significantly. So what are the types of congenital heart disease.

Symptoms of congenital heart disease

First, it can be classified into three types according to hemodynamics and pathophysiological changes. The first one is non shunt. There was no shunt or cyanosis on the left and right sides, such as pulmonary artery stenosis, aortic stenosis, aortic coarctation, primary pulmonary artery dilatation, primary pulmonary hypertension or dextrocardia.

Second: left to right shunt. There are abnormal channels in the left and right cardiac cavities or between the main and pulmonary arteries. The pressure of the left side is higher than that of the right side. The left artery blood flows into the right venous blood through the abnormal channels and flows to the left and right, such as atrial septal defect, ventricular septal defect, patent ductus arteriosus, main pulmonary septal defect and partial anomalous pulmonary venous drainage.

Third, there are right to left shunt. The pressure in right cardiac cavity or pulmonary artery increased abnormally, and the blood flow flowed into left cardiac cavity or aorta through abnormal channel. Cyanosis usually occurs shortly after birth, such as tetralogy of Fallot, triad of Fallot, tricuspid atresia, persistent arterial trunk, transposition of great vessels, Eisenmenger's syndrome, etc.

matters needing attention

Before birth, some parts of the heart of some fetuses do not develop normally, which will lead to changes in the normal blood flow through the heart, forming the so-called "congenital heart disease". The above is the type of congenital heart disease, if you find the above symptoms, it is recommended to go to the heart specialist hospital for examination and treatment as soon as possible.
