Peri\u2010procedural anticoagulant was a direct thrombin inhibitor (DTI) in 6051 (49.2%) procedures. Cavo\u2010tricuspid isthmus, superior vena cava, mitral isthmus linear ablation, Vein of Marshall (VoM) ethanol infusion, and non\u2010pulmonary vein AF trigger ablation were performed in 6590 (51.4%), 2834 (22.1%), 1138 (8.9%), 733 (5.7%), and 729 (5.7%) procedures, respectively. Cardiac tamponade occurred in 84 (0.64%) (0.59% after index and 0.80% after re\u2010do) procedures. Among them, 61 (0.48%) procedures required pericardiocentesis with a median of 300 [167\u2013500] mL of drainage, and 4 (0.03%) required surgical intervention. All patients recovered without sequelae.
