Balloon expandable THV. (a–c) The SAPIEN 3 balloon expandable is constituted by cobalt-chromium alloy frame valve with bovine pericardium leaflets. A polyethylene terephthalate fabric skirt on the distal section of the frame serves for PVL serves prevention. The device is introduced in the market in the following sizes: 20 mm, 23 mm, 26 mm, and 29 mm (a). The Commander Delivery System is 14 F expandable introducer sheath compatible for 20-26 mm valves and 16 F expandable introducer sheath compatible for 29 mm valves (b and c). (d–g) Self expandable THV. The bioprosthesis is manufactured by suturing 3 valve leaflets and a skirt, made from a single layer of porcine pericardium, onto a self-expanding, multilevel, radiopaque frame made of Nitinol (d–g). CoreValve (d), Evolut R (e), Evolut PRO (f) in the following sizes: 20 mm, 23 mm, 26 mm, and 29 mm. ©. The loading System (g). The outer diameter of the catheter is 15 Fr (AccuTrak™ stability layer) and 12 Fr, and the outer diameter of the valve capsule is 18 Fr. The catheter can be used for femoral, subclavian/axillary, or ascending aortic (direct aortic) access sites.
