[Late perforation of the right ventricle by displacement of pacemaker electrodes (report of 2 cases)].
We report two cases of late perforation of the right ventricle due to arrow head endocardial electrodes, used for pacemaker stimulation in patients with complete atrio-ventricular block. Comments on the treatment of this complication are made. In one case the electrode was removed and the myocardium sutured. In the second case the distal part of the electrode was left in the pericardial cavity. In both cases epicardial electrodes were placed to continue the stimulation changing the site of implantation of the power source.
