[Cerebral protection in transcatheter aortic valve implantation].

The review is devoted to transcatheter aortic valve implantation (TAVI). Aortic stenosis (AS) is one of the most common valve diseases in the world and cause of premature death. TAVI is an important advance in the treatment of patients with severe aortic stenosis, particularly in those with moderate and high surgical risk. However, this method has some complications. Stroke prevention and development of strategies reducing the incidence of this event are not only important therapeutic goals for patients undergoing TAVI, but also have significant economic implications.
