valve replacement

Valve replacement is a surgical procedure to repair or replace a damaged heart valve that isn't functioning properly. The heart has four valves that control blood flow, and if one becomes infected, narrowed, or leaky, it can cause symptoms like fatigue or shortness of breath. During the procedure, the surgeon removes the faulty valve and replaces it with a healthy one, which can be made from cow, pig tissue, or a metal or plastic artificial valve. The goal is to restore normal blood flow, improve heart function, and reduce symptoms.
