Why the study?
Does wrapping a pacemaker in a polytetrafluoroethylene sheet prevent skin reactions in patients with contact sensitivity to polychloroparaxylene?
Does wrapping a pacemaker in a polytetrafluoroethylene sheet prevent skin reactions in patients with contact sensitivity to polychloroparaxylene?
Wrapping a pacemaker in a polytetrafluoroethylene sheet is an effective strategy to prevent skin reactions in patients with contact sensitivity to parylene coating.
May prevent recurrent reactions in parylene-sensitive patients; hypothesis-generating case report requiring prospective validation.
Polychloroparaxylene (parylene) is widely used as a material for cardiac pacemaker coating. Contact sensitivity to parylene was proven by patch test. Wrapping the pacemaker in a polytetrafluoroethylene sheet prior to implantation prevented further skin reactions.
