[High-risk patients with aortic valve stenosis. Interventional therapy].

Aortic valve stenosis is the most prevalent, clinically significant valvular disorder in adult patients. Surgical valve replacement is the standard therapy for patients with symptomatic and severe aortic stenosis; however, many patients are suboptimal candidates for surgery due to age and co-morbidities. The development of transcatheter aortic valve implantation (TAVI) has broadened the therapeutic options, especially in high-risk patients. The first randomized study comparing surgical valve replacement with TAVI in operable high-risk patients show similar mortality and reduction in symptoms after a 2-year follow-up. These data support the use of this technique in high-risk patients with severe aortic stenosis.
