Abstract

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.
