The authors present a case of tricuspid regurgitation which reveals a carcinoid syndrome in an 68 year-old woman discovered in view of right heart failure. This carcinoid heart disease is early without symptoms of the primitive or the liver metastatic tumors. We see a good evolution with somatostatin's analogue. We review the diagnosis features in trans-thoracic and trans-oesophageal echocardiography, and the possibility of surgical treatment of these lesions.
