Abstract

Carcinoid heart disease is a rare cause of heart failure with or without right valvular heart impairments. In this study, we showed a case of carcinoid tumour with hepatic metastases inducing carcinoid heart disease. Neuroendocrine heart involvement happens for severe tricuspid valve insufficiency and plaques on right ventricular (RV) walls produced by a release of serotonin (5-HT). A patient affected by primitive ileal tumour with 5-HT-secernent hepatic metastases inducing tricuspid insufficiency is showed. Transthoracic 2-D echocardiography showed tricuspid valve regurgitation and both right atrium, RV-walls plaques and RV dilation. Continue-wave Doppler showed a characteristic “dagger shaped” spectrum of tricuspid systolic flow. RV function was evaluated with 3-D transthoracic echocardiography. In particular, RV volumes, RV ejection fraction and stroke volume were defined by this technique. 2, 3-D echocardiography and Doppler method are useful techniques to show heart valves’ derangements and RV function to non-invasively detect RV impairments in carcinoid heart disease.
