Nonirrigated small (4\u2009mm) and large (8\u2009mm) tip catheters were used as IRE in 14 (including three cross\u2010overs to 8\u2009mm IRE) and five patients, respectively. A total number of 164 bipolar applications were performed (128 for 4\u2009mm and 36 for 8\u2009mm IRE). Maximal temperatures of 4\u2009mm IRE were significantly higher than those of 8\u2009mm IRE (63\u00b0C\u2009\u00b1\u200916\u00b0C vs 43\u00b0C\u2009\u00b1\u20094\u00b0C; <jats:italic>P<\/jats:italic>\u2009=\u2009.027). A significant rise of temperature and steam\u2010pops, preventing further Bi\u2010RFCA, occurred in seven patients treated with 4\u2009mm IRE. Bi\u2010RFCA using 4\u2009mm IRE operated at significantly higher impedance values (211\u2009\u00b1\u200983 vs 143\u2009\u00b1\u200938; <jats:italic>P<\/jats:italic>\u2009=\u2009.04) and lower power values (mean 20\u2009W\u2009\u00b1\u20096\u2009W vs 32\u2009W\u2009\u00b1\u20097\u2009W, <jats:italic>P<\/jats:italic>\u2009=\u2009.0005; max 29\u2009W\u2009\u00b1\u20099\u2009W vs 39\u2009W\u2009\u00b1\u200910\u2009W, <jats:italic>P<\/jats:italic>\u2009=\u2009.027).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The use of 8\u2009mm IRE for Bi\u2010RFCA is associated with lower temperatures of the catheter used as ground and lower incidence of steam\u2010pops which may suggest a better safety profile than 4\u2009mm IRE.
