Tricuspid regurgitation (TR) is a cardiac valve condition whereby the tricuspid valve, situated between the right atrium and right ventricle, fails to seal correctly. The condition lets blood flow backwards into the right atrium, which increases heart work and could lead to consequences.
Causes
Conditions such as rheumatic heart disease, infective endocarditis, or pulmonary hypertension can cause either congenital or acquired TR. Additional reasons include past heart valve surgery, atrial fibrillation, and heart failure. Occasionally it may arise from dilation of the right ventricle brought on by pulmonary disorders or too much fluid retention.
Symptoms
Usually, mild TR shows no symptoms at all. Severe cases, however, might include shortness of breath, stomach pain, leg swelling, tiredness, and abnormal heart rhythms. Untreated TR could cause right-sided cardiac failure over time.
Treatment management relies on degrees. While moderate to severe TR may call for drugs like diuretics or surgical treatments like valve repair or replacement, mild episodes need regular monitoring. For high-risk patients, advances in minimally invasive approaches—including transcatheter valve therapy—have expanded treatment choices.
Prevention of problems and enhancement of heart function depend critically on early diagnosis and suitable therapy.
