Ventricular septal defect surgery is often divided into surgical operations and interventional treatments by the Department of Internal Medicine. For interventional treatments, it is important to rest in bed for 24 hours afterwards. Also, the site of the puncture needs to be immobilized for at least eight hours, so it is important to regularly check the heart with an echocardiogram after the surgery. After surgical operations, it is important to maintain a balanced diet with easily digestible foods. Within a month after surgery, try to avoid strenuous activities, and regularly check the heart with an echocardiogram under the guidance of a doctor.
