[An unusual tricuspid regurgitation]

Area of Science:

• Cardiology
• Oncology
• Medical Imaging

Background:

• Carcinoid syndrome is a rare condition caused by neuroendocrine tumors that can metastasize to the heart.
• Cardiac involvement in carcinoid disease typically affects the tricuspid and pulmonary valves, leading to valvular dysfunction.
• Tricuspid regurgitation is a common manifestation of carcinoid heart disease.

Observation:

• A 59-year-old woman presented with a heart murmur and signs of right heart failure.
• Echocardiography revealed significant remodeling of the tricuspid valve apparatus, resulting in massive regurgitation.
• These findings led to the diagnosis of carcinoid syndrome with cardiac involvement.

Findings:

• Carcinoid heart disease presents with a characteristic echocardiographic appearance of valvular and subvalvular thickening and retraction.
• Massive tricuspid regurgitation is a hallmark of right-sided carcinoid heart disease.
• Early diagnosis through echocardiography is essential for timely management.

Implications:

• This case highlights the importance of considering carcinoid syndrome in patients with unexplained tricuspid regurgitation and right heart failure.
• Understanding the echocardiographic features of carcinoid heart disease is critical for accurate diagnosis.
• Effective management strategies for carcinoid heart disease involve addressing both the underlying carcinoid syndrome and the cardiac manifestations.
