Aktueller Stand der kathetergestützten Aortenklappenimplantation

For selected patients, transcatheter aortic valve implantation (TAVI) has emerged as an accepted alternative to surgical aortic valve replacement for treatment of severe symptomatic aortic stenosis. The procedure has undergone a rapid evolvement since the first-in-man procedure in 2002. New devices have been introduced, implantation techniques modified and preoperative imaging modalities refined. Due to the favorable results achieved, the expansion of the indications for TAVI is the subject of current debate. Furthermore, a transfemoral-first approach is becoming favored more and more by many centers. The aim of this article is to give an update on current clinical practice and to summarize contemporary issues under debate.
