Metastatic tumour of right atrium mimicking constrictive pericarditis and tricuspid stenosis.

Though secondary cardiac tumours are 20 times more common than primary lesions,' and cardiac metastases are found in up to 19% of necropsies undertaken on patients who have died of cancer,2 correct diagnosis of secondary spread to the heart is rare. We describe a patient in whom an unrecognised right atrial metastasis was clinically mistaken for constrictive pericarditis while results of cardiac catheterisation suggested tricuspid stenosis.
