Explore NCDR Science Presented at HRS 2026
Several abstracts being presented at HRS 2026 in Chicago are using NCDR data. The research explores trends and outcomes related to irrigated radiofrequency catheters for accessory pathway ablation in pediatric patients, ICD procedures in patients with ventricular assist devices, and intracardiac echocardiography (ICE) for percutaneous left atrial appendage occlusion.

Utilization and Outcomes of Irrigated Radiofrequency Catheters For Accessory Pathway Ablation in the Pediatric Population
April 24 at 10 a.m. CT | Abstract Pavilion, PO-01-291
Sunita J. Ferns, MD, et al., investigated use, safety and outcomes trends of irrigated radiofrequency catheter for pediatric accessory pathway ablation. Including pediatric patients captured by the ACC's IMPACT Registry, they found irrigated catheter use increased from 2016 to 2025, with comparable safety and efficacy to non-irrigated radiofrequency catheters.
In-Hospital Outcomes of ICD Procedures in Patients With Ventricular Assist Devices
April 24 at 10 a.m. CT | Abstract Pavilion, PO-01-252
Including more than 800,000 ICD procedures from the ACC's EP Device Implant Registry, Andrew Lin, MD, et al., explored the incidence of ICD generator changes and de novo implants in patients with ventricular assist devices over time, finding a downward trend. Procedural complications were low, including pocket hematoma (0.8% for generator change, 0.6% for de novo implant), infection (0.2% and 0.3%), and lead dislodgement (0.1% and 0.6%). They note additional studies looking at longer term outcomes are needed.
ICE vs. TEE-Guided LAAO Using Watchman FLX: Comparative Safety and Effectiveness
April 24 at 4:20 p.m. CT | Heart Rhythm Hub 4, CE-534535-003
Enrico Ferro, MD, et al., compared the use and outcomes of ICE vs. transesophageal echocardiography (TEE) for percutaneous LAAO. Including 97,729 patients from the ACC's LAAO Registry, they found from 2020 to 2022 that ICE use made up less than 10% of LAAO cases. Although ICE and TEE had similar procedural success, ICE exhibited lower general anesthesia use and more same-day discharge but greater periprocedural pericardial effusion and myocardial infarction.
Navigate the EP Landscape With Real-World Evidence
ACC's AFib Ablation Registry provides hospital and health systems with robust, real-world evidence to navigate the rapidly evolving electrophysiology (EP) landscape. Understand outcomes of pulsed field ablations alongside key patient factors, gain deeper insight into both safety and effectiveness, capture outcomes through one-year follow up, and leverage provider-level reporting to identify opportunities for continuous improvement. With comprehensive benchmarking tools, your program can optimize performance and elevate patient care. Learn more.
