Thrombus entrapped in tricuspid chordae masquerading as tumour.

We report on a 55-year-old man with effort dyspnoea that transesophageal echocardiography disclosed was due to a mass originating from the chorda of the tricuspid valve. Histological examination revealed the mass to be an organized thrombus without tumour components. This case illustrates the unusual presentation of a thrombus confined to the tricuspid chordae mimicking a chordae tumour.
