Over time, the mitral and tricuspid valves of the heart undergo changes that lead to insufficiency, meaning they no longer close properly. As a result, blood flows backward instead of forward. This causes functional heart failure with symptoms such as shortness of breath, fatigue, and weakness. In very advanced cases, there may be swelling in the legs and fluid accumulation in the lungs. The modern treatment for these conditions is a semi-robotic therapy using a catheter inserted through the leg. This treatment is performed under general anesthesia and guided by three-dimensional ultrasound. At the site of the valve insufficiency, where it does not close properly, a clamp is inserted to bring the various parts of the valve closer together. This therapy has the advantage of not requiring a sternotomy, as in open-heart surgery, allowing for a much faster recovery and a lower risk of complications. Three days after the treatment, the patient can return home.
