Why the study?
Does enclosing permanent pacemaker and ICD pulse generators in a stretch-polyester pouch reduce the frequency of pulse generator migration and extrusion in patients undergoing device implantation?
Does enclosing permanent pacemaker and ICD pulse generators in a stretch-polyester pouch reduce the frequency of pulse generator migration and extrusion in patients undergoing device implantation?
Enclosing pacemaker and ICD pulse generators in a stretch-polyester pouch is an effective method to decrease the frequency of device migration and extrusion.
May support pouch use in device implants; hypothesis-generating and requires randomized confirmation before practice change.
This study was undertaken to assess the effects of enclosing permanent pacemaker and ICD pulse generators in a stretch-polyester pouch prior to implantation. Follow-up of 223 patients with oversized pacemakers and with ICDs and 344 with standard-sized pacemaker pulse generators showed that the pouch was effective in decreasing the frequency of pulse generator migration and extrusion.
