Abstract:
Patients with symptomatic aortic valve disease who are inoperable or have high surgery-related risks may be treated with transcatheter aortic valve implantation devices. With this method increasingly applied, device innovations are aimed at achieving improved procedural results and therapeutic outcome. This paper describes the innovations implemented in the St. Jude Medical Portico™ system for transcatheter aortic valve implantation, the application of this system and initial clinical experience.
