D-PO05-178 - Declining Rates Of Major Complications Associated With Atrial Fibrillation Ablation: A Decades’ Experience (ID 580)


Background: Catheter ablation has increasingly been used to treat atrial fibrillation (AF). Evolving technologies and operator experience have improved its safety.
Objective: Examine the trends of rates and types of major complications associated with AF catheter ablation over the past decade.
Methods: Post ablation trends in major 30-day complications were examined over three 2-year periods (2009-2010; 2014-2015 and 2018-10/2019) at a tertiary academic hospital. 30-day major complication data were obtained by individual chart review and patient follow-up. Rates of different major complications across the three time periods were summarized. Logistic regression was used to test for a trend in the rate of major complications over the three time periods.
Results: 726, 698 and 778 AF ablations were performed in 2009-2010, 2014-2015 and 2018-2019, respectively. We found a consistent decrease in rates of cardiac tamponade and stroke/transient ischemic attack over the past decade. The incidence of vascular access complications decreased with time but remains the most common procedural complication. Atrio-esophageal fistula and pulmonary vein stenosis are exceedingly rare complications (Fig. 1A). There was a significant trend towards decreasing incidence of major complications across the three time periods (p<0.001). Major complications occurred in 4.96%, 2.29% and 1.3% of patients who underwent ablations in 2009-2010, 2014-2015 and 2018-2019, respectively (Fig. 1B).
Conclusion: Significant strides have been made in improving the safety of AF ablations over the past decade. These findings may inform the risk/benefit assessment for patients considering catheter ablation for AF.
