Complications from modern permanent pacemakers are common, with 11% of patients requiring invasive procedures. Most issues arise within the first three months post-implantation, but mortality is not linked to pacemaker therapy.

Area of Science:

  • Cardiology
  • Medical Devices
  • Clinical Research

Background:

  • Limited data exists on modern permanent endocardial pacing complications.
  • Existing data is largely outdated, from the 1970s.
  • Recent reports focus on specific or early complications, lacking a comprehensive view.

Purpose of the Study:

  • To evaluate complications associated with modern permanent endocardial pacemaker therapy.
  • To provide a comprehensive overview of early and late complications.
  • To assess the need for invasive procedures due to pacemaker complications.

Main Methods:

  • Retrospective review of 446 patients receiving permanent endocardial pacemakers (Jan 1990 - Dec 1995).
  • Analysis of patient records for complications during implantation and follow-up.

  • Categorization of complications into early, late, procedural, and specific types.

    • Main Results:

    • Early complications occurred in 6.7% of patients; 4.9% required invasive treatment.
    • Late complications developed in 7.2%; 6.3% needed reoperation.
    • Pacemaker infection (1.8%) and erosion (0.9%) were noted. 11% of patients required invasive procedures overall.
    • 68% of complications occurred within the first 3 months post-implantation.

    Conclusions:

    • Complications related to modern permanent endocardial pacemaker therapy are not infrequent.
    • A significant percentage of patients require invasive procedures due to complications.
    • While not uncommon, pacemaker therapy did not result in attributable mortality in this study.
