1.What is congenital heart disease? There are two types of heart disease: congenital and acquired. The so-called congenital heart disease is due to the interference of various adverse factors during the mother’s pregnancy, resulting in the fetus in the growth and development of the heart, large blood vessels and other aspects of its form, function and other abnormalities, the fetus has a heart disease at birth. 2.Can congenital heart disease be cured by taking medicine? No, it cannot. 3.What is the best age for treatment of congenital heart disease? Congenital heart disease is a kind of disorder that seriously endangers the growth and development of infants and children. It not only makes the children weak and sickly since childhood, but also affects the development of their intelligence. Therefore, experts and scholars at home and abroad agree that once congenital heart disease is detected, it should be treated as soon as possible. 4.What is interventional treatment for congenital heart disease? Commonly speaking, interventional treatment of congenital heart disease is a treatment between medicine and surgery, which can also be understood as the treatment of congenital heart disease without surgery. It is a treatment method to cure congenital heart disease by using a catheter to deliver the necessary devices to the heart abnormality through the femoral artery or vein under the fluoroscopy of a large X-ray machine. 5.What are the advantages of congenital heart disease interventional treatment? Interventional treatment for congenital heart disease has the following advantages: less trauma, less pain, shorter hospital stay, higher success rate, no need for tracheal intubation anesthesia, etc.; and does not leave any scars to achieve the purpose of radical cure. 6.Which congenital heart diseases can be treated by interventional methods? Although interventional treatment of congenital heart disease has many advantages, only some congenital heart diseases can be treated by interventional treatment due to the limitation of operation technology, method and treatment equipment. For example: congenital heart disease arteriovenous ductus arteriosus, pulmonary valve stenosis, pulmonary arteriovenous fistula; partial atrial septal defect, ventricular septal defect, coronary arteriovenous fistula, aortic stenosis, pulmonary artery stenosis and limb vascular malformation, etc. 7.How is interventional treatment for congenital heart disease performed? First, various routine examinations must be performed at the hospital before the operation. During the procedure, the patient is awake (basic anesthesia is used for children under 5 years old); the femoral artery or vein is punctured, and the balloon, blocker and other interventional devices are delivered to the heart vessel disorder through the catheter that travels through the blood vessels, and treatment is performed depending on the type of disease (including balloon dilation, blocking, embolization, etc.). After the treatment is completed, the catheter is withdrawn from the body and local compression is applied to stop the bleeding. Patients can be discharged from the hospital after 3 days without affecting their normal life, study, or work, and most patients do not require additional medication after the procedure. The whole procedure takes about 1.5 hours on average. 8.Will congenital heart disease recur after interventional treatment, or will the same heart malformation appear again as the child grows older? No. Interventional treatment of congenital heart disease is radical surgery, and as long as the treatment is successful, there is no problem of recurrence. 9.At present, what is the level of interventional treatment for congenital heart disease in China? Interventional treatment of congenital heart disease in China has developed rapidly in the past 10 years and has reached the international advanced level and is in the leading position. With the expansion of publicity and the popularization of medical knowledge, more and more patients prefer this treatment method. It is believed that this advanced treatment method will bring good news to more patients.
