Tricuspid and right ventricular infundibular obstruction associated with calcified right ventricular pseudo-tumour. Radiologic and pathologic aspects.

The authors describe a rare 'pseudo-tumour' in the right heart, discovered after a cerebrovascular accident (paradoxal embolus probably). The mass occupied the anterior leaflet of the tricuspid valve. Its mobility and numerous calcifications facilitated diagnosis, determination of its exact position, and evaluation of haemodynamic consequences. The histopathologic features are reported, and its aetiology is discussed.
