Adult atrial septal defect is a type of congenital heart disease. The symptoms of adult atrial septal defect are typically reduced activity tolerance and chest tightness and shortness of breath. The general cost of the procedure is between 30,000 and 40,000 RMB, but it varies depending on the hospital in different regions. If an atrial septal defect is diagnosed, the first step is to have an ultrasound of the heart to determine the type and size of the defect. During the surgery, a suitable pericardial patch will be selected to carry out the repair treatment. After the surgery, cardiac diuretic and myocardial nutritional drugs will be taken to improve the heart function, and regular review will be done so that the patient can achieve a healthy goal.
