Figure Legends:
Figure 1. A. The J-Valve prosthesis is constructed from a porcine aortic root (black arrow) mounted and sutured on a two-part self-expanding Nitinol stent frame. The support frame and three anchor rings (asterisk) are connected with three anchor connectors (blue arrow), resulting in an adjustable connection. B. Each anchor ring is wholly seated in each sinus of the Tricuspid aortic valve (TAV). C. Two anchor rings can be completely seated in the same sinus of the Bicuspid aortic valve (BAV). D. Placement of the stent valve at the position of the native aortic annulus, clip and attach the native aortic valve leaflets to the device and release of the stent.
Figure 2. Preoperative and postoperative aortic valve morphology. Multiplanar reconstruction of baseline computed tomography in axial views and coronal views at the Valsalva level (A, B, C) and corresponding reconstruction of the aortic root after THV implantation (D, E, F).
Figure 3. The procedure of implantation. (A/E). The delivery catheter is advanced through the native valve into the ascending aorta and verifies the anchor ring is above the native leaflets. (B/F). The positioning anchors are released and the seating of anchor rings in each sinus was checked using tactile feedback. (C/G). Placing the valve at the native aortic annulus position, clipping and attaching the native aortic valve leaflets to the device, and releasing the stent (D/H). Aortography is performed to assess valve function.
Figure 4. Echocardiographic Valve Performance. Echocardiographic evaluation depicting severe noncalcified central AR before transcatheter aortic valve implantation (A, B). Color Doppler was confirming the optimal function of the implanted J-Valve transcatheter heart valve. No paravalvular leaks were detected (C, D).
