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.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
