Procedural characteristics
The main procedural characteristics are shown in Table 2 . Athletes were treated almost 1:1 with cryo and RF ablation, while in NA RF was chosen in most of cases [RF 21 (55%) vs 35 (92%), P=0.00057; cryo 17 (45%) vs 3 (8%), P = 0.00012]. LA target different from pulmonary veins was ablated only in NA [8 (21%) vs 0, P = 0.0129], while CTI was performed significantly more often in athletes [16 (42%) vs 5 (13%), P = 0.0047].
