Battery Longevity in Modern Implantable Cardioverter-Defibrillators and Cardiac Resynchronization Therapy-Defibrillators.

ABSTRACT:

Background

Battery longevity in high-voltage devices (HVDs), specifically implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy-defibrillators (CRT-Ds), is critical for reducing the frequency of generator replacements, minimizing procedural risks, and enhancing patient outcomes. Despite technological advancements, significant variability in battery performance remains among the major manufacturers. This study aimed to evaluate the battery longevity among ICDs and CRT-Ds from the major manufacturers implanted at a single institution and identify the factors influencing battery depletion.

Methods

We conducted a retrospective analysis of 353 patients implanted with HVDs (63 Abbott, 150 Boston Scientific, 140 Medtronic) at Hokkaido University Hospi
