Technik der Transkatheter-Aortenklappenimplantation : Transapikaler und transfemoraler Zugang (Operative Techniken)

Catheter-based aortic valve implantations are innovative and truly minimally invasive procedures. Their use is currently limited to patients with a significantly increased perioperative risk for conventional aortic valve replacement, mainly due to lack of long-term follow-up data. Therefore, a critical evaluation of indications is warranted. Nevertheless, in clinical practice their use has become of increasing importance to patients and physicians alike. To be able to employ these techniques successfully, knowledge of the operational steps and interventional techniques is paramount. To avoid complications, careful preoperative work up and an experienced and well-trained team of surgeons, cardiologists, and anesthetists are necessary.
