Figure 2. Factors impacting coronary access after redo-TAVI in prostheses with a sub-coronary or supra-coronary risk plane. (A) Factors
impacting coronary access after TAV-in-SAV. (B) Sub-coronary risk plane and supra-coronary risk plane. RP: risk plane; SAV: surgical
aortic valve; TAV: transcatheter aortic valve; VTC: virtual transcatheter heart valve to coronary distance; *means VTSTJ; VTSTJ: virtual
[14]
transcatheter heart valve to sinotubular junction distance. From Tarantini et al. (permission for publication obtained).
Figure 3. Impact on coronary access of misaligned high THV commissural posts: (A) commissure height of different transcatheter heart
[14]
valves; and (B) examples of neo-commissure alignment versus misalignment with the native coronary ostia. From Tarantini et al.
(Permission for publication obtained).
