xenograftkleppen

Xenograftkleppen, also known as animal tissue heart valves, are biological prostheses used to replace diseased or damaged human heart valves. These valves are typically derived from porcine (pig) or bovine (cow) pericardium. The tissue is carefully processed and mounted onto a frame, usually made of a metal alloy or a polymer, to create a functional valve that can be surgically implanted.

The use of xenograft valves offers several advantages, including a lower risk of blood clots compared to mechanical valves, which often means patients do not need to take lifelong anticoagulant medication. They also tend to be quieter than mechanical valves, which some patients find more aesthetically pleasing. However, xenograft valves have a limited lifespan and can degenerate over time, potentially requiring re-operation.

The implantation of a xenograft valve is a major surgical procedure performed under general anesthesia. The diseased valve is removed, and the new xenograft valve is sutched into place. The surgical team carefully checks for proper function and to ensure there are no leaks. Post-operative care involves monitoring for complications and managing recovery. Ongoing research continues to focus on improving the durability and performance of xenograft valves.
