Figure 4 Influence of Size or Shape of the Orifice on the Valved Stent Deployment
No leaflet distortion was present with the valved stent (VS) deployed inside the circular orifice with a 25-mm diameter (A). Conversely, distortion occurred after deployment of the VS in an elliptic (B), a triangular (C), or an undersized circular orifice (D).

Figure 5 Leaflet Distortion in the Presence of Annular Calcification Close to One Commissure of the Deployed Valved Stent
Calcification, mimicked by an irregularity (left, arrow) inside the circular orifice, leading to valve distortion (right).

Figure 6 Valve Distortion Secondary to the Valved Stent Deployment Inside a Triangular Orifice
The severity of valve distortion was clearly dependent on positioning of the valved stent commissures inside the orifice (less severe in the left panel than in the right panel).
