Abstract：Objective To explore the impact of radiofrequency ablation treating paroxysmal atrial fibrillation(PAF) and chronic atrial fibrillation(CAF) on cardiac tamponade. Methods A total of 5 313 patients with atrial fibrillation who had radiofrequency ablation for the first time in Beijing Anzhen Hospital,Capital Medical University between January 2013 and December 2016 were retrospectively analyzed. There were 3 295 cases of PAF and 2 018 cases of CAF. Relation between type of atrial fibrillation and cardiac tamponade was analyzed. Results Incidence of cardiac tamponade showed no significant difference between PAF and CAF patients[0.9％(29 /3 295) vs 0.6％(12 /2 018) ](P = 0.248). Volume of pericardial draining was similar between them (P = 0.763). Eight cases(27.6％) of delayed cardiac tamponade occurred in PAF patients. One CAF patient (8.3％) required urgent cardiac surgery repair. Stratified analysis revealed that male,oral anticoagulants,left atrial diameter < 40 mm,left ventricular ejection fraction < 64％ and operative time≥120 min had lower risk of cardiac tamponade in CAF group compared to those in PAF group(odds ratio = 0.403,0.458,0.397,0.187 0.423; all P < 0.05 ). Conclusion CAF does not increase the risk of cardiac tamponade during ablation procedure.
