Summary

Tined transvenous pacing leads demonstrated excellent stability in large dogs over 12 months, even with daily exercise. This suggests tined leads and careful implantation minimize displacement risks in cardiac device studies.

Area of Science:

  • Veterinary Cardiology
  • Biomedical Engineering
  • Implantable Devices

Background:

  • Transvenous pacing leads are crucial for cardiac device function.
  • Lead displacement is a potential complication impacting device efficacy.
  • Tined leads are designed for secure atrial and ventricular fixation.

Purpose of the Study:

  • To evaluate the long-term stability of tined transvenous pacing leads in large-breed dogs.
  • To assess lead anchoring during an experimental implantable defibrillator study.
  • To identify potential complications associated with tined pacing leads.

Main Methods:

  • Tined transvenous pacing leads were implanted in nine healthy large-breed dogs.
  • Leads were used to induce ventricular fibrillation at specified intervals.

  • Lead stability was assessed over a 12-month experimental period, including daily exercise.

    • Main Results:

    • Tined leads remained securely anchored to the right ventricular apex for up to 12 months.
    • No significant lead displacement occurred despite daily running exercise.
    • Minor complications included mechanical endocarditis and one instance of ventricular wall penetration.

    Conclusions:

    • Tined transvenous pacing leads exhibit robust anchoring in large dogs.
    • Careful implantation techniques and the use of tined leads can minimize lead displacement.
    • These findings support the reliability of tined leads in cardiac electrophysiology research.
