title: [Extraction of tricuspid valve tissue and myocardium as a complication of transvenous cardiac pacing (author's transl)].
abstract: In a patient with transvenous cardiac pacemaker a piece of tissue, 5,5 cm in length, was removed from the wall of the right heart during the extraction of a "shouldered" electrode (Biotronik IE 85-K-O). Histologically it consisted of fibrous tissue as usually found around transvenous electrodes, tricuspid valve tissue, chordae tendineae, and myocardium. Detrimental consequences to the patient following this complication were not observed. Some problems caused by trapped endocardial electrodes and adequate therapeutic possibilities are discussed.
