Popis: Abstract Background Cardiac tamponade is a serious complication of catheter ablation for atrial fibrillation (AF). However, the outcomes of catheter ablation in patients of cardiac tamponade are unknown. Methods We performed catheter ablation in 2467 sessions of AF or a recurrence of AF between January 2007 and January 2016. Of these, 29 events in 27 patients (1.18%: 22 men; 64.5 ± 10.4 years; 17 with paroxysmal AF) of cardiac tamponade during or after the procedure were recorded. The clinical characteristics and outcomes of these 29 events were studied in detail. Results Of the 19 events where the ablation procedure was completed, seven events developed acute recurrence of AF (36.8%). Of the 10 events with an incomplete procedure, 10 exhibited AF recurrence (100.0%). Direct oral anticoagulants were used in seven events, and clinical outcomes were not significantly different compared to the remaining 21 events that were prescribed warfarin. Pericarditis occurred in 10 events (34.5%) after the procedure, and the incidence rate was lower in patients receiving prophylactic nonsteroidal anti‐inflammatory drugs or steroids (2/15, 13.3% vs 8/14, 57.1%; P = 0.013). Repeated sessions were performed in 12 events (two with a complete initial procedure, 10 with an incomplete initial procedure). Freedom from atrial arrhythmias was observed in 27 events (93.1%, 9 with antiarrhythmic drugs) over midterm follow‐up (3.1 ± 2.6 years). Conclusion Although cardiac tamponade caused by catheter ablation led to a high rate of acute AF recurrence and pericarditis, the midterm recurrence rates of AF are unaffected if the procedure can be completed.
