Bench evaluation of MyVal OCTACOR THVs at expansion limits for paediatric and valve-in-valve applications.

Balloon-expandable MyVal OCTACOR valves were evaluated in 3D-printed conduits under simulated flow. The 20 mm valve functioned from 16-24 mm, rupturing at 27 mm. The 29 mm expanded to 33 mm with mild insufficiency. Findings suggest OCTACOR valves may support repeated valve-in-valve procedures, with the 20 mm showing greater versatility for small-infant mitral replacements and as a potential alternative to Melody valves.
