Atrial Fibrillation Friday, September 27th, 2013

CIRCULATIONAHA: September 23, 2013

Background—AF ablation has tremendous progress with respect to innovation, efficacy and safety. However limited data exists regarding burden and trends in adverse outcomes arising from this procedure. The aim of our study was to examine frequency of adverse events due to Atrial Fibrillation (AF) ablation and influence of operator and hospital volume on outcomes.

Methods and Results—Using the Nationwide Inpatient Sample (NIS) we identified AF patients treated with catheter ablation. We investigated common complications including cardiac perforation and/or tamponade, pneumothorax, stroke, transient ischemic attack (TIA), vascular access complication (consisting of hemorrhage/hematoma, vascular complication requiring surgical repair, and accidental arterial puncture), and in-hospital death described with AF ablation and defined them by validated International Classification of Diseases (9th Edition) Clinical Modification (ICD-9-CM) diagnosis codes.  Read more
