Congenital heart disease is the most common type of congenital malformation, accounting for about 28% of all congenital malformations. It refers to an anatomical abnormality caused by the formation or abnormal development of the heart and large blood vessels during embryonic development, or the failure to close channels that should close automatically after birth (which is normal in the fetus). What should I do if I have congenital heart disease? There are two types of treatment for congenital heart disease: surgical treatment and interventional treatment. Surgical treatment is the main treatment for simple congenital heart disease (e.g., ventricular septal defect, atrial septal defect, arteriovenous ductus arteriosus, etc.) and complex congenital heart disease (e.g., congenital heart disease with pulmonary hypertension, tetralogy of Fallot, and other heart diseases with cyanosis). Interventional therapy is a new treatment method developed in recent years, mainly for children with unclosed ductus arteriosus, atrial septal defect and partial ventricular septal defect that are not combined with other anomalies requiring surgical correction. The difference between the two mainly lies in the fact that surgical treatment has a wider scope of application and can cure all kinds of simple and complex congenital heart diseases, but there is a certain degree of trauma, longer recovery time after surgery, a few patients may have arrhythmias, chest and heart cavity effusion and other complications, and also leave surgical scars affecting the aesthetics. Interventional treatment is narrower in scope and more expensive, but non-invasive, with quick post-operative recovery and no surgical scars. What is the best time to treat precardiac disease? The optimal best time for surgery depends on a variety of factors, including the complexity of the congenital malformation, the age and weight of the child, the general development and nutritional status of the child, and also on the technical level of the surgical unit. Generally, for simple congenital heart, it is recommended to be 1-5 years old, because too young, low weight, poor general development and nutritional status will increase the risk of surgery (if severe congenital heart, or if the technical level of the surgical unit is in place, surgery can be performed as early as possible); too old, the heart will compensate for the increase in size, and in some cases, there will even be an increase in pulmonary artery pressure, which will also increase the difficulty of surgery and longer recovery time after surgery. For combined pulmonary hypertension, congenital malformations that are severe and affect growth and development, malformations that threaten the life of the child, and complex malformations that require staged surgery, the earlier the surgery the better, regardless of age. Is there any possibility of healing in precordial disease? No. In general, precordial heart disease cannot heal on its own and requires surgery or intervention to cure. However, for ventricular or atrial defects with a diameter of less than 0.5 cm, no treatment is necessary, as it will not adversely affect the heart function or growth of the child. However, due to the presence of heart murmur in children, which has certain impact on future education, employment and marriage, and the surgery is now very mature, some parents still choose surgery due to these social factors. There are also some small defects, such as ventricular defects in the sub-stem area, which are less than 0.5 cm due to their proximity to the aortic valve, and they also require active surgical treatment. For children with defects larger than 0.5 cm in caliber, surgery is recommended. Care of congenital heart disease Try to keep the child quiet, avoid excessive crying, and ensure sufficient sleep. Older children should have a regular life, combining movement and stillness, neither running around outside (running, jumping and strenuous sports are strictly prohibited) nor lying in bed all day, and sleep must be guaranteed at night to reduce the burden on the heart. Children with cardiac insufficiency tend to sweat more, so they need to keep their skin clean, bathe regularly in summer, rub themselves with hot towels in winter (pay attention to keeping warm), and change their clothes and pants regularly. Feed more water to ensure sufficient hydration. Keep the stool smooth, if the stool is dry and difficult to defecate, excessive force will increase the abdominal pressure, increasing the burden on the heart, and may even have serious consequences. Keep the air circulating in the room, and avoid staying in crowded public places to reduce the chance of respiratory tract infection. Add and remove clothes in time with the warm weather and pay close attention to the prevention of colds. Regular follow-up visits to the cardiology clinic of the hospital and strict compliance with medical prescriptions, especially for cardiac and diuretic drugs, due to their pharmacological properties, the dosage must be absolutely controlled and taken on time and according to the course of treatment to ensure their efficacy. Before each dose of cardiac drugs, the pulse count must be measured, if the heart rate is too slow, should immediately stop taking, to prevent the occurrence of toxic effects of drugs, endangering the life of the child.
