CardioNETPOL National Registry of Carcinoid Heart Disease

Carcinoid tumors are neuroendocrine tumors (NETs), most commonly originating from the gastrointestinal tract, that may secrete bioactive substances such as serotonin. Persistent exposure to these mediators can lead to carcinoid syndrome and, in up to 50% of patients, carcinoid heart disease (CHD). CHD is characterized by fibrotic degeneration of cardiac valves, predominantly right-sided, resulting in progressive valvular dysfunction and a significant increase in mortality. The mechanisms underlying selective cardiac involvement and predictors of disease progression remain incompletely understood. In addition, optimal timing and selection of surgical versus transcatheter valve interventions, particularly in high-risk patients, require further clarification. This multicenter, retrospective observational registry aims to identify and characterize patients with carcinoid heart disease and at least moderate valvular involvement. CHD is defined by confirmed neuroendocrine tumor, echocardiographic evidence of ≥ moderate valvular disease with features of fibrosis, elevated NT-proBNP (\>260 ng/L), and histopathological confirmation when available. Approximately 100-120 consecutive patients will be enrolled over 12 months. Standardized data collection will include detailed echocardiographic assessment, demographic and clinical characteristics, cardiovascular risk factors, comorbidities, tumor features, oncological treatment history, and cardiac management strategies. The primary objective is to describe the clinical profile and management of patients with CHD in a real-world multicenter setting. Secondary objectives include identifying factors associated with advanced valvular dysfunction and evaluating eligibility and outcomes of transcatheter valve therapies. The registry is expected to improve risk stratification and support clinical decision-making in carcinoid heart disease.

Investigation of a Transcatheter Tricuspid Valved Stent Graft in Patients With Carcinoid Heart Disease

The purpose of this investigation is to see if the TRICENTO Valved Stent Graft implant reduces tricuspid regurgitation (TR) and improves the symptoms and quality of life in 15 participants with carcinoid heart disease, and who are not able to have a new valve via a surgical procedure.

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.
