Tricuspid regurgitation

Tricuspid regurgitation is a cardiovascular disease where the tricuspid valve of the heart does not close properly, causing blood to flow backwards into the right atrium when the right ventricle contracts. This condition can lead to various symptoms and complications, and is often diagnosed through echocardiography.

Causes

Tricuspid regurgitation can be caused by several factors. Primary tricuspid regurgitation is often due to abnormalities of the tricuspid valve itself, such as congenital heart disease, endocarditis, or carcinoid heart disease. Secondary tricuspid regurgitation is more common and is usually due to dilation of the right ventricle, which can occur in conditions such as pulmonary hypertension, right ventricular infarction, or left-sided heart failure.

Symptoms

Symptoms of tricuspid regurgitation can vary depending on the severity of the condition. They may include fatigue, shortness of breath, swelling in the abdomen or lower extremities, and palpitations. In severe cases, tricuspid regurgitation can lead to right-sided heart failure.

Diagnosis

Tricuspid regurgitation is typically diagnosed through echocardiography, which can visualize the flow of blood through the heart and detect any abnormalities in the tricuspid valve. Other diagnostic tests may include electrocardiogram (ECG), chest X-ray, and cardiac MRI.

Treatment

Treatment for tricuspid regurgitation depends on the underlying cause and the severity of the condition. It may include medication, surgery to repair or replace the tricuspid valve, or catheter procedures.
