A condition where the tricuspid valve does not close properly

Tricuspid regurgitation (TR) is a disorder of the heart in which the tricuspid valve does not close tightly, allowing blood to flow backward into the right atrium when the right ventricle contracts. This condition can lead to various symptoms and complications if left untreated.

Causes

Tricuspid regurgitation can be caused by several factors, including:

• Rheumatic fever
• Infective endocarditis
• Congenital heart defects, such as Ebstein's anomaly
• Pulmonary hypertension
• Right ventricular dilation

Symptoms

Symptoms of tricuspid regurgitation may include:

• Fatigue
• Swelling of the abdomen or legs (edema)
• Pulsing in the neck veins
• Ascites
• Hepatomegaly

Diagnosis

Diagnosis of tricuspid regurgitation typically involves:

• Echocardiography
• Electrocardiogram (ECG)
• Chest X-ray
• Cardiac MRI

Treatment

Treatment options for tricuspid regurgitation depend on the severity of the condition and may include:

• Diuretics to reduce fluid retention
• Surgery to repair or replace the tricuspid valve
• Management of underlying conditions such as pulmonary hypertension

Prognosis

The prognosis for individuals with tricuspid regurgitation varies based on the underlying cause and the severity of the condition. Early diagnosis and treatment can improve outcomes.
