Tricuspid insufficiency is a medical condition that occurs when the tricuspid valve in the heart fails to function properly. This can lead to a backflow of blood into the right atrium, causing the heart to work harder to pump blood to the rest of the body. There are several synonyms for tricuspid insufficiency, including tricuspid regurgitation, tricuspid valve incompetence, and tricuspid valve regurgitation. Additional related terms may include right-sided heart failure, pulmonary hypertension, and right ventricular hypertrophy. Treatment for tricuspid insufficiency can range from medication to surgical procedures depending on the severity of the condition and the patient's overall health.
