Figure 1. Commissural alignment with Hydra THV. Computed tomography showing severe aortic valve stenosis (A1), with 3-cusp view reconstruction (A2). The novel Hydra THV (A3) with the three-tentacle design (1,2,3) and commissural posts (red arrows) at their bases; six radiopaque markers are located three by three in two rows (black asterisks), each asymmetrically positioned between two prosthetic commissures (dashed lines).
