Figure 1. Overview of investigated ablation strategies.
Visual representation of the individual ablation strategies investigated
in the study: 1) Durably isolated Pulmonary Veins (no additional
ablation); 2) Pulmonary Vein Antralization; 3) Linear-Based Ablation:
roof line, inferior line, posterior wall [both as box made using roof
and inferior lines, as well as whole posterior wall (shaded red
area)], cavo-tricuspid isthmus line, mitral isthmus line; 4)
Trigger-Based Ablation: superior vena cava, coronary sinus, left atrial
appendage, other triggers; 5) Low-Voltage Area Ablation; 6) CFAE
(Complex Fractionated Atrial Electrograms) Ablation; 7) Other
Strategies: vein of Marshall ablation, rotor ablation
