Pulmonary open-surgery heart valve bioprosthesis

Pulmonary open-surgery heart valve bioprostheses are biological valves derived from animal tissue (such as pig or cow) designed to replace or repair a damaged pulmonary valve during open-heart surgery. These devices are used to treat congenital or acquired valvular disorders, restoring proper blood flow through the heart’s pulmonary artery while maintaining long-term durability and function.

These bioprostheses are typically regulated as surgical implants, often requiring clinical validation for safety and performance before market authorization. They may be supplied as standalone tissue grafts or mounted on structural frameworks to ensure proper positioning and function during implantation.
