HRS 2021: Modeling long-term effect of biventricular defibrillator battery capacity on major complications and costs associated with replacement procedures.
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.
We developed a model to estimate cost and complication rate variations associated between 1.0Ah, 1.6Ah, and 2.1Ah battery CRT-D generator replacements over a period of 20 years.
Dr. Williams obtained his undergraduate degree with a double major in Biomedical and Electrical Engineering at Vanderbilt University. He was then awarded a Keck Fellowship for graduate school at the University of Pittsburgh where he obtained his Master’s degree in Bioengineering.
Dr. Williams went on to obtain his medical degree at Drexel University in Philadelphia and completed 5 years of Fellowship training in both Cardiovascular Diseases and Clinical Cardiac Electrophysiology at the University of Pittsburgh Medical Center.
His unique background and extensive knowledge of both engineering and cardiology have earned Dr. Williams many accolades in both clinical and academic settings. He’s published over 20 manuscripts and abstracts in the field of cardiology/electrophysiology and has received awards from both the American College of Cardiology Foundation and the National Institutes of Health.
Dr. Williams started in the Invasive Electrophysiology Laboratory at The Good Samaritan Hospital in 2008 and the Heart Rhythm Center published outcomes on pacemaker and defibrillator implantations as well as the safety and efficacy of high frequency jet ventilation during EP studies with ablation under his direction. He is Chair of the Quality Committee at the Florida Chapter of the American College of Cardiology.
