Development and Progression of Carcinoid Heart Disease in a Cohort of Adult Patients With Neuroendocrine Tumors

"Patient at high risk of Carcinoid Heart Disease (metastatic ileum or bronchial well-differentiated neuroendocrine tumors, patients with high level of urinary 5HIAA or with carcinoid syndrome) are followed with annual echocardiography to detect the occurrence of carcinoid heart disease.~In case of documented Carcinoid Heart Disease, a six or three months' cardiac follow-up is necessary to evaluate the progression and the severity of the disease.~Investigators collect the data of clinical parameters (flushes, diarrhea, …) biological parameters (urinary 5HIAA, NT-ProBNP …) and cardiac parameters that may influence the occurrence, severity and progression of Carcinoid Heart Disease."
