Transcatheter valve implantation to inferior vena cava to control carcinoid symptoms

Severe carcinoid syndrome and carcinoid heart disease in neuroendocrine tumours can have a significant impact on a patient's quality of life and are a major cause of morbidity and mortality. We present a novel approach to managing a patient with medically uncontrollable carcinoid syndrome. Inferior and superior vena cava placement of transcatheter heart valves has been used to treat patients with right heart failure due to severe tricuspid and pulmonary regurgitation. However, this procedure has not been attempted to specifically reduce hormone secretion, primarily from the liver, in order to control carcinoid syndrome symptoms. We attempted this procedure in a patient with severe carcinoid disease and tricuspid regurgitation as a bridge to later definitive therapy. The procedure was technically successful, but did not improve carcinoid symptoms. The possible reasons for the failure are discussed here.
