High density mapping accuracy and efficiency in atrial fibrillation: real-world outcomes from the SECURE registry

Abstract

On behalf of the SECURE Investigators Funding Acknowledgements: Type of funding sources: Private company. Main funding source(s): Biosense Webster, Inc. Background/Introduction: A high-density (HD) mapping catheter is valuable for validating pulmonary vein isolation (PVI) and analysing arrhythmic substrates of the left atrium (LA) during atrial fibrillation (AF) ablation. Multiple HD mapping catheters are available for use in clinical practice. A novel octa-spline mapping catheter with a close internal unipolar reference electrode is now available and may improve mapping efficiencies and image resolutions (Figure).
