Single-lead VDD and dual-lead DDD pacing systems offer effective AV-synchronous stimulation for high-degree AV-block. VDD systems present advantages in shorter implantation times, reduced fluoroscopy, and lower costs.

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Medical Devices

Background:

  • High-degree atrioventricular (AV) block necessitates pacing for physiologic AV-synchronous stimulation.
  • Single-lead VDD and dual-lead DDD pacing systems are established options for managing this condition.

Purpose of the Study:

  • To compare the efficacy, safety, and cost-effectiveness of single-lead VDD pacing versus dual-lead DDD pacing in patients with high-degree AV block.
  • To evaluate implantation parameters, lead function, P-wave sensing reliability, and potential complications associated with each system.

Main Methods:

  • Comparative analysis of VDD and DDD pacing systems in patients with high-degree AV block.
  • Assessment of implantation times, fluoroscopy duration, perioperative complications, ventricular lead performance, and P-wave sensing reliability.

Related Experiment Videos

  • Evaluation of cost implications and the impact of sinus node function on system choice.

    • Main Results:

    • Both VDD and DDD systems achieve nearly complete AV-synchronous stimulation with high P-wave sensing reliability (mean >99%).
    • VDD systems demonstrate significantly shorter implantation times (up to 40%) and reduced fluoroscopy (up to 55%) with a trend towards fewer perioperative complications.
    • Ventricular lead function is comparable between systems; VDD systems offer potential cost reductions and avoid atrial pacing, which is relevant if sinus node disease develops.

    Conclusions:

    • Single-lead VDD and dual-lead DDD pacing systems provide similar effective and reliable AV-synchronous stimulation for high-degree AV block.
    • VDD systems offer advantages in terms of easier implantation, reduced fluoroscopy, and lower costs, making them a favorable option in many cases.
