[Transcatheter aortic-valve implantation].

Aortic valve stenosis is associated with severe morbidity and death within several years of symptom onset, and its accepted treatment is surgical aortic valve replacement. However, many affected patients are not referred for surgery because of old age and significant comorbidities. In recent years, an alternative treatment approach has been developed, transcatheter aortic-valve implantation. In this review we would like to describe this treatment modality and to present several cases performed in our center.
