Figure legend:
figure 1: total procedural time, time to PVI, and RF time (primary endpoint)
Standard: AI guided PVI using standard power settings according to the CLOSE-protocol; HPSD AI guided PVI using fixed 50W power setting relying to the CLOSE-protocol; total procedure time: time from groin puncture to bandage; time to PVI: time from groin puncture to complete electrical isolation of the pulmonary veins; RF time: total radio frequency application time (data presented as mean±SEM, p<0.05 was defined as significant)
figure 2 : Thermal oesophageal lesions - representative figures
time course of thermal oesophageal lesions visualized with EGD
Standard ablation: A and B: typical deep ulcerations with slow healing tendencies.
HPSD Ablation: C-E superficial mucosal detachment; F typical ulcer (KCC 2a) with healing tendencies after one week; G deep, fibrin covered ulceration (KCC 2b) with very slow scarring healing over 12 weeks
