Degenerative aortic stenosis is associated with aging. Unfortunately, no therapy has been proven to alter the rate of progression of aortic stenosis.Surgery can help repair or replace the aortic valve. Factors such as age, heart health and general state of health will determine the treatment procedure.Aortic valve repair: Surgery can be minimal or extensive depending on the valve problem.Aortic valve replacement: This can be done through conventional surgery or with a minimally invasive procedure, such as transcatheter aortic valve implantation, which is used to treat severe aortic stenosis. In this heart valve surgery, a balloon catheter is used to insert a tissue valve through a cut in the groin or chest.
