The catheter is designed to enable high\u2010density mapping and precise signal recording via 48 small electrodes arranged on eight radiating splines. The purpose of this study was to compare bipolar voltage and low\u2010voltage\u2010area size, and mapping efficacy between the OCTARAY catheter and the PENTARAY\n \u00ae<\/jats:sup>\n catheter\n <\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Twelve consecutive patients who underwent initial and second ablations for persistent atrial fibrillation within 2 years were considered for enrollment. Voltage mapping was performed twice, first during the initial ablation using the PENTARY catheter and second during the second ablation using the OCTARAY Long 3\u20103\u20103\u20103\u20103 (L3) catheter.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Mean voltage with the OCTARAY\u2010L3 catheter (1.64\u00a0\u00b1\u00a00.57\u00a0mV) was 32.3% greater than that with the PENTARAY catheter (1.24\u00a0\u00b1\u00a00.46\u00a0mV,\n p<\/jats:italic>\n \u00a0<\u00a0.0001) in total left atrium. Low\u2010voltage\u2010area (<0.50\u00a0mV) size with the OCTARAY\u2010L3 catheter was smaller than that with the PENTARAY catheter (6.9\u00a0\u00b1\u00a09.7\u00a0vs. 11.4\u00a0\u00b1\u00a013.0\u00a0cm\n 2<\/jats:sup>\n ,\n p<\/jats:italic>\n \u00a0<\u00a0.0001). The OCTARAY\u2010L3 catheter demonstrated greater efficacy than the PENTARAY catheter in terms of shorter mapping time (606\u00a0\u00b1\u00a099\u00a0vs. 782\u00a0\u00b1\u00a0211\u00a0s,\n p<\/jats:italic>\n \u00a0=\u00a0.008) and more mapping points (3,026\u00a0\u00b1\u00a0838\u00a0vs. 781\u00a0\u00b1\u00a0342 points,\n p<\/jats:italic>\n \u00a0<\u00a0.0001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The OCTARAY catheter demonstrated higher voltage recordings, narrower low\u2010voltage areas, and a more efficacious mapping procedure than the PENTARAY
