The patients were divided into two groups: the reversed S\u2010curve technique group (RST, <jats:italic>n<\/jats:italic>\u2009=\u200926) and the reversed C\u2010curve technique group (RCT, <jats:italic>n<\/jats:italic>\u2009=\u200933). The RST under the support of a steerable sheath was used in RST group, while the RCT under the support of a nonsteerable sheath was used in the RCT group.

Two patients experienced cardiac tamponade in the RCT group, while no complications were observed in RST group (<jats:italic>p<\/jats:italic>\u2009=\u2009.498). The success rate was significantly higher in RST group compared to RCT group (81.9% vs. 100%, <jats:italic>p<\/jats:italic>\u2009=\u2009.029). Three patients in RCT group failed to ablate during the operation but were successfully ablated using the novel method.
