Tricuspid Valve Regurgitation

What is tricuspid valve regurgitation?

The tricuspid valve is a crucial component of the heart’s intricate machinery, playing a vital role in ensuring the unidirectional flow of blood. Tricuspid valve regurgitation, a cardiac condition, occurs when this valve doesn’t close properly during the heart’s pumping cycle, leading to the backflow of blood into the right atrium. This condition can compromise the heart’s efficiency and, if left untreated, may result in serious complications.

Types of tricuspid valve regurgitation

Tricuspid valve regurgitation can be categorised into two main types: organic and functional.

Organic regurgitation is typically caused by structural abnormalities of the tricuspid valve itself, such as congenital malformations or degenerative changes.

Functional regurgitation, on the other hand, is often secondary to changes in the heart’s size and function, commonly associated with conditions like pulmonary hypertension or left-sided heart diseases.

Causes of tricuspid valve regurgitation

Several factors contribute to the development of tricuspid valve regurgitation.

Organic regurgitation may arise from congenital abnormalities, infective endocarditis, or rheumatic heart disease.

Functional regurgitation, meanwhile, can be triggered by conditions like pulmonary hypertension, left-sided heart failure, or atrial fibrillation. Understanding these causes is crucial for accurate diagnosis and targeted treatment.

Symptoms of tricuspid valve regurgitation

Recognising the symptoms of tricuspid valve regurgitation is essential for early intervention. Patients may experience fatigue, swelling in the abdomen or legs (edema), and an increased heart rate. In more severe cases, symptoms may progress to liver enlargement and pulsatile neck veins. The insidious onset of these symptoms emphasises the importance of regular cardiovascular check-ups, especially for individuals with known risk factors.

Treatment available for tricuspid valve regurgitation

Treatment options for tricuspid valve regurgitation depend on the severity of the condition and its underlying causes. In milder cases, close monitoring and lifestyle modifications may be sufficient. However, as the condition progresses, medical intervention may be necessary. Minimally invasive tricuspid valve repair or replacement, has emerged as a favourable option, allowing for precise correction of valve function with reduced recovery times compared to traditional open-heart surgery.

Risks & complications of tricuspid valve regurgitation

Neglecting tricuspid valve regurgitation can have serious consequences. As the condition worsens, the heart’s pumping efficiency diminishes, leading to the accumulation of fluid in various body tissues. This fluid build-up can result in congestive heart failure, affecting the lungs, liver, and other vital organs. Furthermore, untreated tricuspid valve regurgitation may contribute to irreversible damage, increasing the risk of life-threatening complications.
