Congenital heart disease is a common condition in infants and children, some of which can heal on their own with age, while some require timely treatment. Most of them can be cured, and a small number of complex congenital heart disease can be close to normal life after surgery. A. Parents are alert to children with congenital heart disease when they have the following symptoms? 1, usually shallow and rapid breathing, profuse sweating, wasting, slow weight gain; 2, crying, feeding or shortness of breath aggravated after activity, and blue lips; 3, usually repeated colds and pneumonia; 4, some children have fingernails, lips and cheeks are dark purple; 5, cyanotic congenital heart disease special posture: infancy like to flex in the arms of adults; older children like to squat; 6, some congenital heart disease may not have 6, some congenital heart disease may not have obvious symptoms, only in the occasional physical examination heard heart murmur. What should congenital heart disease patients pay attention to in their daily lives? 1, to avoid infection, avoid children to crowded environment, home often open windows, air disinfection (vinegar fumigation, etc.), 2, severe children should not be excessive exercise, so as not to increase the additional burden on the heart. 3, cyanotic precordial disease children like to flexion or squatting position, which is the performance of compensatory hypoxia, can not be forcibly changed to avoid the risk. Third, when is it good to treat precordial disease? In principle:Once congenital heart disease is found, it should be diagnosed by a cardiologist to guide the timing of treatment. 1.Some of the mild atrial and ventricular septal defects, patent ductus arteriosus and pulmonary valve stenosis may heal spontaneously and need to be reviewed in a cardiologist outpatient clinic. 2.In the absence of significant pulmonary hypertension, heart failure and recurrent severe infections, most precordial diseases can be treated before school age. 3.The presence of cyanosis in precordial disease requires timely advance treatment. Fourth, interventional treatment of congenital heart disease without surgery is a mature technology and is the first choice for some precocious heart diseases. Interventional treatment of congenital heart disease without surgery is to use a very thin catheter to deliver a blocker from the inguinal vessels to the defect in the heart to block the gap in order to achieve radical cure of congenital heart disease. If the indications for intervention are properly selected, the success rate can be as high as 98% or more. Interventional cardiac therapy is already the treatment of choice for pulmonary stenosis and patent ductus arteriosus. 80% of atrial septal defects can be treated with interventional therapy, and interventional techniques for ventricular septal defects are becoming increasingly sophisticated. The age of interventional treatment is becoming younger and younger. V. Can children with congenital heart disease receive vaccination? 1, common congenital heart disease, if there is no serious cardiac insufficiency and other contraindications to vaccination, should be vaccinated. 2. For children with cardiac insufficiency, especially complicated cyanotic congenital heart disease, vaccination may need to be suspended.
