Study Details

Pulsed Field Ablation (PFA) represents a recent advance in the treatment of atrial fibrillation (AF), with a safety profile potentially superior to traditional thermal techniques, such as radiofrequency or cryoablation. Its mechanism of action allows tissue selectivity which in theory limits damage to extracardiac structures. However, several cases of right diaphragmatic paralysis have been reported in the literature after PFA, particularly during applications on the right pulmonary veins, near the right phrenic nerve. The available data are from studies without specific diaphragmatic monitoring. The diagnosis of diaphragmatic paralysis is most often based on chest X-ray, a static examination of limited sensitivity, especially for the detection of incomplete paralysis. To date, no prospective multicentre study has evaluated the incidence of diaphragmatic paralysis after PFA with systematic dynamic imaging, such as fluoroscopy, considered the gold standard for the diagnosis of unilateral paralysis.

Arms

  • Experimental: Intervention
    Systematic observation of an additional examination (dynamic fluoroscopy) performed before and after a Pulsed Field Ablation procedure, as part of the standard management of atrial fibrillation.

Primary Outcome Measure

Diaphragmatic paralysis [ Time Frame: Day1: Before the Pulsed Field Ablation and after the Pulsed Field Ablation (at hospital discharge between 2 and 30 hours after ablation, according to a rigorously standardized protocol in all participating centres) ]
