Abstract

Introduction: While several studies have reported on the reliability of cardiac pacing leads, there are limited comparative data on lead performance. We compared long‐term performance of Abbott Tendril™ STS 2088TC (Tendril 2088) leads with competitive manufacturer (CM) pacing leads using novel real‐world data analytic methods. Methods: Medicare fee‐for‐service (FFS) claims and Abbott device registration databases were linked to identify patients implanted with single‐chamber or dual‐chamber pacemakers with the Abbott Tendril 2088 lead from January 1, 2014 to December 31, 2019 and were followed through December 31, 2021. Medicare pacemaker patients who did not link to Abbott devices were assumed to have CM leads. Patients in both groups had to be enrolled in Medicare FFS at least 1 year before implant date and have an initial pacemaker and associated lead(s) implanted on the same date. Lead complications were identified based on a diagnosis code for a mechanical lead complication and a procedure code for a lead‐related surgery on the same claim. Kaplan‐Meier curves for lead intervention‐free survival rates for up to 7 years of follow‐up were compared between groups at the device level using a log‐rank test. Results: The study cohort had 89 629 Tendril 2088 and 433 481 CM lead patients. Groups were comparable in age (79.7 ± 8.6 years), sex (52.2% male), race/ethnicity, and baseline comorbidities. At 7 years, there was no significant difference in intervention‐free survival rates between groups (97.48% Tendril 2088 vs. 97.52% CM, p =.3435). Conclusion: In this large Medicare population, there was no significant difference in lead complication rates between Tendril 2088 and CM pacing leads over 7 years of follow‐up.

Abstract

This work is the first attempt to explore the supercapacitor applications of Barium nickelate (BaNiO3) perovskite nanoparticles. The nanoparticles are synthesized using a simple combustion method and their morphology, elemental composition, and so forth are studied using standard characterization methods such as x‐ray diffraction spectroscopy (XRD), field emission scanning electron microscopy (FESEM), and so forth. The nanoparticles were found to be hexagonal in shape, with an average particle size of 16 nm, and the elemental analysis confirms the successful synthesis of the BaNiO3 perovskite nanoparticles. For electrochemical studies, the electrodes are fabricated over a wearable and flexible conductive fabric (CF) substrate. A slurry paste of the synthesized BaNiO3 nanoparticles is applied over CF and dried overnight, thereby forming a thin film electrode. The fabricated electrode acts as a positive electrode with a high specific capacitance of 508.64 F g−1 at 2.2 A g−1 current density. Upon increasing the current density, the electrode maintains 60% of its specific capacitance and displays 97% cyclic stability over 5000 cycles. The electrochemical impedance spectroscopy (EIS) study indicates excellent conductivity of the electrode, with a bulk resistance of 3.2 Ohms. The electrochemical performance of the fabricated electrode is also compared with various previously reported works and the electrode displays higher specific capacitance and better cyclic stability. These findings suggest that the BaNiO3 perovskite nanoparticles‐based electrode holds promise for utilization as an anode material in supercapacitor applications. [ABSTRACT FROM AUTHOR]
