Tricuspid regurgitation is a heart condition characterized by the improper closure of the tricuspid valve, which separates the right atrium and right ventricle. This results in the backflow of blood from the right ventricle into the right atrium during each heartbeat. Tricuspid regurgitation can be caused by various factors, including structural abnormalities, heart disease, or functional issues. Common symptoms may include fatigue, swelling in the legs and abdomen, and shortness of breath. Trea
