Abstract: | A 56-year-old woman presented with general fatigue, dyspnea on exercise, and hepatomegaly subsequent to secondary implantation of a pacemaker. On admission, cardiac echo examination showed tricuspid valve regurgitation due to a migrated looped lead. At surgery, there was evidence of severe stenosis at both orifices of the superior and inferior vena cavae due to fibrous tissue around the leads. We removed the fibrous tissue, pacing leads, and generator. New leads were anchored onto the epicardium and a generator was inserted under the rectus muscle. The postoperative course was satisfactory and the symptoms disappeared. |
