Carcinoid heart disease CHD is a paraneoplastic cardiac manifestation occurring in patients with carcinoid syndrome CS and advanced neuroendocrine malignancy.
These substances cause plaque-like deposits to form on endocardial surfaces resulting in predominantly right-sided valve abnormalities. Pulmonary vasectomy was performed in nine patients and pulmonary valve replacement with a pulmonary homograft was performed in one. In about 2040 of patients with CS chronic exposure to tumor-released circulating vasoactive peptides typically results in right-sided valvular fibrosis leading to valve dysfunction and right heart failure.
The pathophysiology of carcinoid heart disease is not well understood. Valvular dysfunction can lead to oedema ascites and right-sided heart failure. Carcinoid heart disease HD was first reported in 1952 1 and typically occurs in patients with advanced carcinoid tumors and carcinoid syndrome.
However carcinoid heart disease which eventually occurs in up to 50 percent of patients with carcinoid syndrome and may be the initial presentation of carcinoid disease in as many as 20 percent of patients remains a major cause of morbidity and mortality among patients with carcinoid syndrome. Valvular dysfunction can lead to oedema ascites and right-sided heart failure. CHD remains a significant cause of morbidity and mortality.

Valve surgery for carcinoid heart disease.
Progress in the treatment of patients with carcinoid disease has resulted in improved symptom control and survival. It is typically manifest as right-sided valvular lesions usually tricuspid insufficiency and pulmonary valve stenosis. This case report describes the unusual presentation of a patient with carcinoid heart disease and a large right-to-left shunt.
Development and progression of carcinoid heart disease are. Carcinoid heart disease is a rare form of valvular heart disease. Carcinoid tumors are relatively rare neuroendocrine malignancies most commonly originating from enterochromaffin cells in the gastrointestinal tract with an incidence of 1 per 100000 population.
