Article Snippet: The admIRE trial (NCT05293639) was a multicenter, prospective, nonrandomized, single-arm interventional study to assess the safety and effectiveness of a variable loop PFA catheter (Varipulse Catheter, Biosense Webster Inc., part of Johnson & Johnson MedTech, Irvine, CA, USA) with an integrated electroanatomical mapping system (CARTO Software, Biosense Webster Inc., part of Johnson & Johnson MedTech, Irvine, CA, USA).

Figure Lengend Snippet: Three-dimensional bipolar map of the LA and the right- and left-sided PVs in a posterior–anterior and a left lateral projection. The green dots mark PFA-based lesions around the ipsilateral PVs as applied by the lattice-tip mapping and ablation catheter.

Article Snippet: This catheter can apply PFA as well as radiofrequency (RF) according to anatomical locations and operator’s choice and yields high flexibility for individual ablation strategies., , So far, Affera-based ablation was only performed in general anaesthesia (GA), and there is no experience for procedures in deep sedation., , However, in Europe and the USA, conscious or deep sedation is mainly used for electrophysiology procedures., Catheter ablation in deep sedation using fentanyl, midazolam, and a ketamine adjunct or midazolam, dexmedetomidine, and remifentanil was recently described for ablation with the Farapulse PFA catheter (Boston Scientific) or a variable loop circular PFA catheter (Biosense Webster)., The present study compared the safety and efficacy of Affera procedures with PFA and/or RF applications in atrial fibrillation (AF) patients ablated in deep sedation or in GA.
