The rate of recurrence after infant aortic constriction is based on the condition, which varies in terms of success rate and sequelae. Generally speaking, the success rate is very high and almost no recurrence; in several special cases, the postoperative recurrence rate is high. 1. If the child has simple aortic constriction, with mild and small stenosis, and no combination of other types of malformations, the success rate of the surgery is high and the recurrence rate is low. 2. If the child has severe aortic stenosis with other types of malformations, the surgery has a high risk of recurrence and may result in aortic restenosis and pseudoangiomas. 3. If the child is operated on and the wound sutures do not match, there is a risk of rupture, which can be life-threatening in severe cases. If infants experience discomfort after aortic stenosis surgery, they need to go to a regular hospital for examination and symptomatic treatment.
