If initial ablation was acutely unsuccessful in either group, patients crossed over to the other group. Ablation was acutely successful in 47 of 60 (78.3 %) patients in the NCM group and 55 of 60 (91.7%) in the CM group (<jats:italic>P\u00a0<\/jats:italic>=\u00a0.002). Thirteen NCM patients required CM and two CM patients crossed over to utilize NCM (<jats:italic>P<\/jats:italic>\u00a0=\u00a0.002). Procedural duration, fluoroscopy time, and dose in NCM were greater than that in CM (<jats:italic>P\u00a0<\/jats:italic>&lt;\u00a0.05, respectively). However, procedural complications were not different between two groups. During a mean follow\u2010up of 51 \u00b1 20.6 months, 51 of the 60 NCM patients remained free of arrhythmia, while 48 of the 60 CM patients had no recurrent arrhythmias
