Case ReportsTwo-dimensional echocardiography in the diagnosis of carcinoid heart disease.
Tricuspid valve disease accounts for significant morbidity and mortality in the carcinoid syndrome, but M-mode echocardiography is often insensitive in completely defining the tricuspid valve. We performed two-dimensional echocardiography (2DE) in seven patients with proven carcinoid syndrome. There were five males and two females whose ages ranged from 53 to 79 years. ⋯ The tricuspid valve was best visualized in the parasternal right ventricular long-axis and short-axis views. The apical four-chamber view was less helpful. Thus, 2DE demonstrated specific tricuspid valve abnormalities in the carcinoid syndrome with thickening, shortening, and immobility of the leaflets when valvular regurgitation was present and thickening and doming when the valve was stenotic. 2DE should be a useful method in the diagnosis and sequential evaluation of patients with carcinoid heart disease.
