However, phrenic nerve damage (PND) is a bothersome complication of the procedure. In this study, we aimed to establish the incidence of PND during CB and define the characteristics of affected patients.</p><p><strong><em>Material &amp; Methods:&nbsp; </em></strong></p><p>In this retrospective analysis, all patients with AF that underwent CB ablation between 2013 and 2018 were included into the study. Characteristics and outcomes of patients complicated with&nbsp; PND were evaluated. PNP was detected by palpation of diaphragma contractions or observation of reduced diaphragma motility by fluoroscopy during the procedure.</p><p><strong><em>Results:</em></strong></p><p>Totally 653 patients were included in the study. PND was detected in 3.5% (23/653) of the patients. Median age of the patients with PNP was 56 (25-78) years and 10 patients (43.4 %) were male. The most common ablation site related with PND was RSPV (18 patients, 78%). Transient PND was observed in 16 patients (69%) of the patients which resolved within 24 hours after the procedure. In the remaining 5 patients (21%) diaphragmatic contraction was recovered at the 6<sup>th</sup> month control visit. In 2 patients (10%), phrenic nerve paralysis was still present &gt;1 year visit</p><p><strong><em>Conclusion:</em></strong></p><p>PND is not a rare complication of CB ablation despite all the preventive maneuvers during the procedure and technological developments. However, most of the PND recovered during the follow-up.</p> ER -
