How to detect precocious heart disease? The severity of symptoms varies among the various types of precardiac disease. Both parents and doctors should think about whether a child has precardiac disease when the following symptoms occur: 1. persistent cardiac and respiratory malfunction after birth; 2. restlessness, high pitched cries, weak sucking during feeding, difficulty feeding, and no weight gain; 3. persistent cyanosis or recurrent confusion, easy shortness of breath after crying or activity, and blue lips; 4. 4, repeated “pneumonia” in the lungs; 5, older children will complain of chest tightness, precordial pain, panic, especially after activity, these symptoms are more obvious; 6, some children with cyanotic precordial disease may also appear pestle-like toes (i.e., soft tissue hyperplasia at the end of the hands or toes, in the shape of a mallet), the longitudinal and transverse diameter of the nails are excessively 7, cyanotic precocious heart disease often have several special postures: infancy when holding the legs are not straight, like bending in the adult’s abdomen, sitting when like to lift the feet to the stool surface, standing when the lower limbs to maintain a bent posture. Older children walking, walking a period of time to squat down two knees close to the chest to rest for a moment, medically known as the “squatting” phenomenon. These postures are designed to improve oxygen deprivation; 8. Children with precordial disease are prone to recurrent respiratory infections. Is congenital heart disease curable? Congenital heart disease sounds scary, but most patients with congenital heart disease can be cured, and there are no sequelae. However, the prerequisite for eradication is timely detection and early treatment, and the earlier the treatment, the better the results. ”A few years old can be eradicated, a few years old is difficult to treat, and a few dozen years old is not treated.” After a child, especially an infant, is found to have precocious heart disease, many parents usually feel that the child is too young and will receive treatment when he or she grows up a bit. “This understanding can delay the child.” When the affected child grows up, the organs of the body will develop cyanosis due to lack of oxygen. Once the child develops cyanosis, the disease is very difficult to treat. The earlier the treatment, the better the results. So, how early is the most appropriate treatment? For simple precocious heart disease, the age is around 3 years old and the weight is between 5 and 8 kg, the treatment can be a combination of these two conditions, and most patients are 3 to 5 years old. However, severe and complex congenital heart disease is treated in infants and children even at birth. When to operate when a child has congenital heart disease is an issue of great concern to parents. Many parents believe that their children are too young to withstand the torment of surgery, and that it is safer to wait until the child is older and stronger before performing surgery. Unbeknownst to them, there are many children who have delayed surgery, thus losing the opportunity for surgery and causing lifelong regrets. With the advanced development of modern medicine, the surgery time for children with congenital heart disease cannot be determined by the age and tolerance of surgery. Of course, the tolerance of surgery is correspondingly poorer in younger children, and the risk of surgery is also greater, but if the heart malformation is complex or the lesion is serious, it can lead to blood circulation disorder and cause damage to heart and lung function. Even if the heart malformation can be corrected later, the damaged heart and lung tissues are difficult to recover, and the successful surgery cannot achieve the purpose of cure. Some critically ill children are life-threatening due to untimely surgery. Therefore, the best time for surgery for precordial disease should be determined by the specific condition of the child. For the most common precardiac disease, arteriovenous ductus arteriosus, ventricular septal defect and atrial septal defect, the operation time depends on the size of the defect, such as large defect, large fractional flow, severe pulmonary congestion, often accompanied by heart failure, pneumonia and other co-morbidities, should be operated early, and the operation can be performed in infancy (within 1 year old). For children with severe cyanotic precardiac disease, such as tetralogy of Fallot and pulmonary venous ectopic drainage, surgery should also be performed in infancy if there are frequent episodes of hypoxia. If the condition is not very serious, those with cyanosis but does not affect life can be operated after 1 year of age. For serious cardiovascular malformations, such as misalignment of the aorta; permanent arterial trunk, pulmonary artery closure, etc., surgery should be sought as early as possible according to the different conditions of the sick child. The best time to operate is determined by the cardiologist according to the condition. For children with less serious conditions who can live normally, it is better to operate before school age, so that the child’s life and study after school will not be hindered. In short, precordial disease should be detected early, diagnosed early, and operated early “three early” principle.
