Without knowing much more about your valve, its anatomy, the amount of leakage, and several other factors, there’s little that I can tell you regarding how to prevent surgery nor about your prognosis as to whether you will even need surgery, or not. In general, I can advise you to do a few simple things: avoid significant isometric exercises, such as competitive football, wrestling, or weightlifting; ensure that you have good oral hygiene, including routing dental visits; maintain normal blood pressure and weight; make sure that you have routine cardiology follow-up, and, get routine aerobic exercise. However, despite all this, it is still possible that you may require aortic valve surgery in the future. The goal is not to speed its occurrence up, and to make sure that your heart is in good shape in order to tolerate it. In general, though, aortic valve disease, if it is anything beyond mild in nature, is something that I typically tell patients will be with them for life and will require both follow-up as well as likely intervention, or re-intervention, at some point.
