Left: Schematic representation of lesion placement in catheter and surgical ablation. Most lesions were performed by radiofrequency ablation (thin red or blue lines) but left atrial appendage (LAA) was occluded with a clip (thick red line) and the Ligament of Marshall (LoM) was dissected (dashed green line). Middle: Kaplan–Meier survival plots illustrating freedom from AF/AT (left) and clinical success (right) of both treatments. Right: Graphical representation of symptoms improvement (EHRA score reduction), QALY gained and the total costs associated with both treatments at 12 months.
