A straight or crosier-shaped catheter technique for phrenic nerve pacing during cryoballoon pulmonary veins isolation for treatment of atrial fibrillation.

CONCLUSIONS: Both 'straight' and 'crosier-shaped' catheter technique provides equal efficiency in monitoring the phrenic nerve and avoiding its palsy. The "crosier-shaped" setting maintains its position better thus causing fewer catheter dislocations and requires fewer correction maneuvers, which might correlate with shorter procedure time. Moreover, the "crosier-shaped" technique provides lower pacing thresholds. Both these techniques may be safely used and in case of problems with stable phrenic nerve capture switching for another technique seems reasonable. PMID: 31354159 [PubMed - as supplied by publisher]
