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
