How Do You Spell HEART VALVE PROSTHESES?

1. Heart valve prostheses are medical devices designed to replace and functionally restore the impaired or diseased heart valves. Heart valves are essential structures that regulate blood flow within the heart by ensuring unidirectional circulation. They open and close with each heartbeat to allow the blood to move through the chambers, maintaining proper cardiovascular function.

   When heart valves become damaged or dysfunctional due to congenital defects, infections, or age-related degeneration, heart valve prostheses are utilized to replace these valves and restore normal blood flow. These prostheses can be mechanical or biological in nature.

   Mechanical heart valve prostheses are typically made from durable materials such as metal, carbon, or ceramics. They mimic the natural motion of the heart valve and have a long lifespan. However, patients with mechanical heart valves require lifelong anticoagulant therapy to prevent blood clots from forming.

   Biological heart valve prostheses are created from animal tissues or harvested human tissues. These prostheses may be chemically treated or altered to reduce the risk of rejection and calcification. Biological valves may not require lifelong anticoagulant therapy but tend to have a limited lifespan.

   Heart valve prostheses are surgically implanted through open-heart procedures or minimally invasive techniques. They provide an effective solution for patients with heart valve diseases, improving their cardiac function and quality of life. Regular monitoring and follow-up care are essential for patients with heart valve prostheses to ensure optimal functioning and prevent complications.
