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.

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).
