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.

BACKGROUND: To point out a possible correlation between left atrial volume index (LAVI) and left ventricular (LV) diastolic time interval to better define LV diastolic dysfunction, this study was performed. METHODS: In 62 hypertensive-hypertrophic patients without LV systolic dysfunction, LV volumes, myocardial mass index, ejection fraction% (EF%) and LAVI were measured by two-dimensional echocardiography. Instead, tissue Doppler echocardiography (TDE) was used to measure myocardial performance index (MPI) and its systo-diastolic time intervals, such as: iso-volumetric contraction time (IVCT); iso-volumetric relaxation time (IVRT); ejection time. LAVI, TDE-MPI and time intervals where also measured in 15 healthy controls, to obtain the reference values. RESULTS: Results shown a significant increase of LV volumes in hypertensives in comparison to the control group (p < 0.05). LV mass index also augmented (p < 0.001). Instead, EF% not significantly changed in hypertrophic patients in comparison with healthy controls. LAVI raised in hypertensives wih left ventricular hypertrophy, whereas IVCT resulted within the normal limits. On the contrary, IVRT significantly raised. Accordingly, MPI resulted higher in controls. CONCLUSION: LAVI, MPI and its time intervals appear as reliable tools to non-invasively individualize LV diastolic dysfunction in systemic hypertension, in absence of mitral valve disease.
