We report the case of a 31-year-old woman with a 4-year history of recurrent palpitations, presenting with an increased frequency of paroxysms caused by ventricular tachycardias during pregnancy. A cardiac tumor of unknown origin infiltrating the right ventricle was diagnosed. Three weeks after prophylactic abrasion the tumor was totally excised with the use of cardiopulmonary bypass including restoration of the right ventricular wall and the tricuspid valve. Histology confirmed diagnosis of a benign cardiac lipoma. The postoperative course was uneventful and the patient was discharged 7 days after surgery. There was no episode of ventricular tachycardias during the 6-month follow-up.
