Introduction: Carcinoid heart disease (CHD) is a known complication of neuroendocrine tumors (NETs), particularly of those arising from the small intestine, appendix and proximal colon (previously known as mid-gut carcinoids). CHD is characterized by right heart fibrotic lesions and has traditionally been defined by the degree of valvular involvement, most commonly in the form of tricuspid regurgitation. Right ventricular (RV) dysfunction due to mural involvement may also be a manifestation. Connective tissue growth factor (CCN2) is upregulated in many fibrotic disorders. Increased tumor expression of CCN2 has been shown in patients with small intestinal NETs associated with peritoneal fibrosis. At present, its role in carcinoid heart disease is unknown.
