The success rate of pulmonary atresia surgery is not very high. However, with the development of technology, the success rate is gradually improving. It is generally related to the local medical conditions, the development of the right ventricle, and the body’s ability to recover itself. Pulmonary atresia is caused by embryonic dysplasia. Surgery for pulmonary atresia is similar to surgery for other types of heart disease, but the difference is that patients with pulmonary atresia do not have their own pulmonary artery, and can only rely on the side branches for blood supply, which makes the surgery process extremely dangerous, and the heart can be harmed if one is not careful. Attention should be paid to the postoperative care problems, as much as possible to improve the success rate of the operation. It is recommended that patients should supplement balanced nutrition in a timely manner, try to eat more fluids, can be injected with intravenous fluids to inject nutrients, and try to avoid physical labor and strenuous physical activity.
