A case of 47-year old woman operated on because of a chronic left ventricular false aneurysm caused by Staphylococcus aureus septicemia and endocarditis 8-years earlier is described. After septicemia was cured, clinical status improved so markedly that the patient refused to undergo recommended operation until onset of heart failure (NYHA III). She was operated on from the median sternotomy with the use of cardiopulmonary bypass. After pericardial adhesions were dissected free, the large left ventricular false aneurysm with severely calcified wall was found. The aneurysm was excised completely and its orifice closed with non-absorbable monofilament 3-0 suture. Postoperative course was complicated by epileptic attack accompanied by loss of consciousness and left hemiplegia on 4th day after surgery. Neurological symptoms regressed within 48 hours and on 12th postoperative day she was discharged from a hospital in a good clinical status.
