  1. aFor paroxysmal atrial fibrillation (AF), additional linear ablation was performed only exceptionally; nonparoxysmal AF, use of additional lesions varied by operator, including linear lesions at the roof, mitral isthmus, posterior wall and CTI, targeting of complex fractionated electrograms, and ablation at the endocardial and epicardial aspects of the coronary sinus
  2. bCTI line added in patients with AFL hx; if remained in AF, linear lesions added at mitral isthmus and roof, both point-to-point and drag
  3. cPVI only, PVI with lines, PVI with lines and CFAE, and PVI with CFAE
  4. AFL atrial flutter, hx history n/a not applicable, PVI pulmonary vein isolation, SVT supraventricular tachycardia, CTI cavotricuspid isthmus isolation, CFAE Complex Fractionated Atrial Electrograms, WACA wide antral circumferential ablation
