| Abstract: | A patient is described in whom a sheath-retracting active-fixation pacemaker electrode dislodged shortly after successful transvenous implantation in the right atrial appendage. Attempts to reposition the lead were unsuccessful. Examination of the explanted electrode disclosed that inability to reposition the electrode was due to the fact that impacted tissue around the electrode "screw" prevented its being re-advanced out of its polyurethane housing.
