Pathognomonic echocardiographic features of carcinoid syndrome

FIG. 1 (A) Modified parasternal short-axis view of the triscuspid valve (TV) and right heart chambers, demonstrating marked TV leaflet malcoaptation. (B) Modified parasternal short-axis view of the right chambers. There is a large vena contracta confirming severe triscuspid regurgitation. (C) Continuous-wave Doppler profile of TV inflow showing an early peak pressure and sharp decline. (D) Subcostal hepatic view revealing multiple hyperechogenic lesions that correspond to carcinoid metastases. Images edited by Richard A. Kerensky, M.D.
