The change in the fluoroscopy-guided transseptal puncture site and difficult punctures in catheter ablation of recurrent atrial fibrillation

摘要

Aims A second procedure for recurrent atrial fibrillation (AF) may be associated with the need for a different positioning of the puncture site and may increase the difficulty and complications. This study investigated whether the transseptal puncture site changed and whether the difficult punctures increased in the patients who received a repeat ablation procedure for recurrent AF.
