Treatment for aortic stenosis depends on how far the disease has progressed. If the patient’s stenosis is mild, medication may be prescribed to regulate the heart, prevent blood clots, and manage symptoms. However, medication is a palliative therapy and is not an effective treatment for severe aortic stenosis. The only effective treatment for severe aortic stenosis is to replace the diseased aortic valve. This can be done with open heart surgery or transcatheter aortic valve replacement (TAVR).
