• Carcinoid syndrome was diagnosed in a 48-year-old man by urinary 5-hydroxyindoleacetic acid test results and liver biopsy findings. Cardiac catheterization disclosed tricuspid stenosis and mild pulmonic stenosis. The distinctive echocardiographic findings included a tricuspid valve moving in unison with the annulus and thickened immobile tricuspid leaflets. Unlike in rheumatic heart disease, diastolic doming of the tricuspid leaflets was not seen.
