Congenital heart disease, or congenital heart disease, as the name implies, is a category of congenital malformations of the great vessels of the heart due to abnormal embryonic development of the great vessels of the heart. The incidence of congenital cardiovascular disease is reported to be 8.1 in the United States and about 2 to 5 in China, which means that for every 1000 babies born, there are more than 2 suffering from different types of congenital cardiovascular disease. It can be seen that congenital heart disease is a not uncommon heart problem among children, and at the same time in our country, due to the limitations of medical conditions, it is not uncommon for adults to suffer from congenital heart disease, and we often encounter such cases in clinical practice. There are single and compound malformations of congenital heart disease; and both single or compound malformations have two major categories: non-cyanotic and cyanotic. After birth, the most common congenital cardiovascular malformations are ventricular septal defect and atrial septal defect, with arteriovenous insufficiency in third place; then simple pulmonary stenosis, tetralogy of Fallot, aortic stenosis and aortic constriction, and the above seven malformations account for about 75% of all congenital cardiovascular lesions. What are the manifestations of congenital heart disease? Most of the congenital heart diseases appear to be nothing special at the time of birth. However, when doctors perform careful heart auscultation, they will find a heart murmur. As they get older, precardiac disease may show symptoms such as frequent colds, fever, pneumonia, restricted activity, bruised lips, slowed or stalled growth and intellectual development, and complications of endocarditis or heart failure. When the above symptoms appear, you should go to the hospital as soon as possible. Most of the diagnosis can be confirmed by simple tests such as electrocardiogram, cardiac photograph, color Doppler, etc. A few patients need further tests such as cardiac catheterization to confirm the diagnosis. Without treatment, half of all cases of precardiac disease die by the age of one and two-thirds by the age of two, and the more complex the malformation, the more severe the disease and the earlier the death. Therefore, children should undergo regular health checkups, strive for early diagnosis of children with precocious heart disease, and promptly transfer them to a unit with surgical conditions for consultation and treatment. As the saying goes, congenital deficiencies are mended later in life, and surgical repair and orthopedics are the main means of treating congenital heart disease. The purpose of surgery is to correct the abnormal blood flow caused by malformation and restore it to normal by repairing the anatomical defects or structural abnormalities so that the blood flow can run according to the normal anatomical pathway to complete the normal circulatory function; or to use the method of rerouting or building another channel for the heart that is severely stunted or too complicated to carry out normal physiological function so that the heart and lung function can reach or approach normal in order to obtain the elimination of symptoms, improve function and enhance life. In order to eliminate the symptoms, improve the function, enhance the quality of life, and prolong the life expectancy. Over the past few decades, due to the continuous efforts of cardiac physicians and surgeons, and the accumulation of numerous successful and unsuccessful experiences, cardiac surgery has been able to treat patients of all ages, with all kinds of pathologies and conditions, from its inception to the present, and has achieved a level of increasing efficacy and decreasing mortality.
