Please watch my short presentation given at the 2021 Annual Sessions of the Heart Rhythm Society on July 30, 2021. A 2.1 ampere-hour (Ah) battery capacity biventricular defibrillator (CRT-D) was recently shown to be the first to exceed patient survival in a chronic heart failure cohort. There is consensus that extended battery longevity (based on Ah) can reduce the costs and complications related to generator replacements. Our model revealed that increased utilization of extended longevity CRT-D battery technology (2.1Ah) leads to substantial annual reductions in major complications and costs of replacement procedures.
