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

Carcinoid Heart Disease (CHD) is a rare form of heart disease, occurring in over 50% of the patients with carcinoid syndrome. Pathophysiology, prognostic factors of development of Carcinoid Heart Disease and progression of disease remain unclear. This observational multicenter cohort study is designed to study the occurrence of Carcinoid Heart Disease in patients with differentiated carcinoid tumors, to describe numerous factors influencing the occurrence, severity, progression and long-term survival of patients with Carcinoid Heart Disease. Basic informations and detailed diagnosis informations (oncological and cardiac parameters), are collected by professional doctors. Clinical outcomes (onset of Carcinoid Heart Disease, cardiac surgery, related death) will be followed up every year or every six/three months if clinically indicated.
