Aortic stenosis is the most common structural disease of the heart. The second most common heart surgery is treatment of aortic stenosis by replacing the aortic valve with a prosthetic valve. The classic surgical approach reyuires full sternotomy, general anesthesia, and cardio-pulmonary bypass, hence this procedure is not appropriate for all the patients. With the development of new surgical and non-surgical techniques, treatment of aortic valve stenosis has become available for a larger number of patients. In surgical procedures, the incision is smaller (minimally invasive surgery) and a suturless prosthetic valve can be inserted. Non-surgical techniques include transfemoral transcatheter aortic valve insertion. Indications for surgical or non-surgical approach have not been clarified yet. Transfemoral transcatheter insertion is proven to be more effective for patients with severe aortic stenosis and high perioperative risk. In the article, we present the outcomes of recent studies that included patients with high, medium, and low perioperative risk.
