title: Successful trans-apical aortic valve implantation for a high risk patient with aortic stenosis using a new second-generation TAVI device - J-Valve system.
abstract: Transcatheter aortic valve implantation (TAVI) has evolved as a routine procedure to treat selected high-risk patients with severe aortic stenosis. The new J-Valve prosthesis is designed for antegrade transapical implantation, it is characterized by a porcine aortic prosthesis attaching to a self-expandable Nitinol stent. The key feature of the device are three U-shape anatomically oriented devices - "graspers" which could facilitate intuitive 'self-positioning' valve implantation. Hereby, we report a successful case of trans-apical TAVI in an elderly high-risk patient with severe aortic stenosis using J-Valve system.
