Exercise cardiac magnetic resonance imaging with pulmonary artery catheter monitoring in carcinoid heart disease: a shift towards early intervention?

摘要

Neuroendocrine tumours are a rare malignancy, which can be complicated by a carcinoid syndrome and, in more rare cases, also valve destruction. The correct timing for surgical repair remains unknown. We report the first‐in‐men exercise cardiac magnetic resonance imaging with pulmonary artery catheter measurements in order to better understand the haemodynamic impact of isolated tricuspid valve insufficiency in a low symptomatic patient. Not pressure but volume overload is the key factor in the development of symptoms, as long as the right ventricular function is intact. Based on our findings, we referred the patient for tricuspid valve replacement. This case, together with the review of all carcinoid heart disease cases in our hospital (a large tertiary cardiology and oncology centre) since 2000, indicates a potential benefit for early intervention in carcinoid heart disease.
