Acute Kidney Injury after Catheter Ablation of Atrial Fibrillation: Comparison between Different Energy Sources

Pulsed field ablation (PFA) is an innovative technology recently adopted for treating atrial fibrillation (AF). Preclinical and clinical studies have reported a reassuring safety profile because of its tissue-specific effect, sparing adjacent tissues.1 However, two cases of acute kidney injury (AKI) secondary to hemolysis after PFA have recently been reported after an uncommonly high number of applications.2,3 Similarly, a subsequent pilot study reported the occurrence of AKI in 4/28 patients after PFA for AF.
