Seventy\u2010two (53%) patients had a pre\u2010operative arrhythmia, and 37 patients (27%) had a pre\u2010operative EPS at our center before CR. Nineteen (51%) had a significant finding, and 12 (32%) received a transcatheter ablation. Intraoperative ablation was performed in 86 (64%) patients with cavotricuspid isthmus (CTI) ablation performed in 74 (55%), of which 24 (18%) had a CTI with additional targeted accessory pathway ablation. Postoperative wire studies were performed in 11 (8%). Since implementing our current electrophysiologic diagnostic algorithm, 7% had a follow\u2010up arrythmia and only 1 underwent a postoperative EPS.<\/jats:p>\n                  <\/jats:sec>\n
