Summary

Cardiac pacing system reliability varies among manufacturers, with some having higher rates of recalled devices. Early regulatory and manufacturer actions are crucial to minimize patient distress and costs from future pacemakers and related product issues.

Area of Science:

  • Biomedical Engineering
  • Medical Device Regulation
  • Cardiovascular Technology

Background:

  • A common perception suggests no significant reliability differences among major cardiac pacing system manufacturers.
  • This perception necessitates an objective evaluation of device reliability and regulatory actions.

Purpose of the Study:

  • To assess the reliability of cardiac pacing systems by analyzing US Food and Drug Administration (FDA) regulatory actions.
  • To identify variations in recall rates and risk levels among different manufacturers.

Main Methods:

  • Conducted an extensive review of FDA regulatory actions from July 1974 to June 1987.
  • Collected data on the total number of affected devices for each manufacturer.
  • Calculated the percentage of recalled products using available sales data for two distinct periods.

Main Results:

  • The percentage of high-risk (FDA class I and II) recalled devices varied significantly among manufacturers.
  • One company exhibited a high percentage of high-risk recalls, another had a moderate percentage, and the rest had relatively low percentages.
  • Past deficiencies in recall management by manufacturers were identified.

Conclusions:

  • Cardiac pacing system reliability is not uniform across all manufacturers.
  • Addressing past recall management deficiencies is essential.
  • Proactive regulatory and manufacturer interventions are vital to mitigate future costs and patient suffering associated with device malfunctions.
