Abstract

Here we report a case of a 48-year-old woman with ectopic thyroid tissue in the right ventricle. The tumour involved 1/3 of the ventricle and adhered to the myocardium. T he lesion was removed completely and a bioprosthesis was placed due to tricuspid insufficiency, and then a pacemaker was implanted. The diagnosis was made upon examination of the postoperative tissue. The paper discusses embryological implications of the development of thyroid tissue in the heart. This case is first in the Polish literature.
