A dual\u2010chamber pacemaker with LBBP was implanted using a three\u2010dimensional (3D) electroanatomic mapping (EAM) system, with complete fluoroscopy avoidance. The procedure was successful and safe, with stable pacing parameters and a favorable maternal\u2010fetal outcome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
