![]() The average procedure and fluoroscopy times were 153.0 ± 52.1 and 13.5 ± 8.8 min, respectively. Pulmonary vein (PV) isolation lesion delivery was most commonly guided by lesion index (LSI) ( n = 317, 94.6%), with target value of 4.5–5.0 ( n = 298, 89.0%) for the anterior/roof PV segment and 4.0–4.5 for the posterior/inferior PV segment ( n = 247, 73.7%). An average of 10,843 ± 11,2 ± 6181 points were collected and used use of the AutoMap module was documented in 238 (71.0%). The use of a steerable sheath with the HD Grid was documented in 125 cases (37.3%). The primary indication was paroxysmal ( n = 218, 65.1%) and persistent AF ( n = 117, 34.9%) conscious sedation/monitored anesthesia care was used in 321 cases (95.8%). Among the 335 cases, only 13 were repeat procedures. Results: Procedural data were collected in 335 AF cases from 26 operators at 14 centers in China. Procedural characteristics and workflow were recorded and analyzed. Materials and Methods: Self‐reported procedural data were prospectively collected in cases utilizing HD Grid during the initial phases of commercialization in China. Objectives: To characterize and examine the clinical utilization of a high‐density grid‐style catheter (HD Grid) in atrial fibrillation (AF) ablation procedures in the Chinese population. ![]() Future study may focus on the impact that this technology has on long‐term outcomes.ġSir Run Run Shaw Hospital Zhejiang University School of Medicine, Hangzhou, China, 2Beijing Anzhen Hospital, Beijing, China, 3Guangdong Province Hospital of Traditional Chinese Medical, The Second Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangdong, China, 4West China Hospital of Sichuan University, Chengdu, China, 5Beijing Royal Integrative Medicine Hospital, Beijing, China, 6Abbott, Minneapolis, USA, 7Tongji Medical College of HUST, Wuhan, China The most commonly utilized OT certainty settings were 0.5 (61.4%) and the nominal setting of 0.3 (30.7%).Ĭonclusion: The initial experience with OT included utilization across a variety of arrhythmias, trending higher in more complex cases which may suggest that the new clinical functionality introduced by this technology aids in substrate characterization and identification of ablation targets during challenging cases. Utilization rate of OT was higher in complex cases (31.4% SVT 37.0% PAF 49.5% PersAF 73.5% VT). Considering only those cases utilizing OT, VoXel mode selected for 90.0%. Overall navigation mode selection was VoXel 62.7% of cases NavX in 37.3%. Indication for mapping and ablation included AF (81.0%), SVT (11.4%), and VT (7.6%). Results: Procedural data were prospectively collected in 448 cases from 37 operators at centers in Japan, Australia, and Hong Kong. Procedural characteristics recorded included indication for mapping and ablation, OT utilization and settings, and navigation mode utilization. Materials and Methods: Procedural data were collected in cases performed in the Asia Pacific region utilizing the EnSite X mapping system. This analysis sought to evaluate utilization and associated mapping settings for this novel technology. This technology enables EGMs to be analyzed in 360 degrees, eliminating artifact introduced by the orientation of a recording bipole relative to the activation wavefront. Objectives: EnSite Omnipolar Technology (OT) was recently introduced on the EnSite X EP system in the Asia Pacific region. 1Toyota Kosei Hospital, Toyota, Japan, 2Higashi Takarazuka Sato Hospital, Hyogo, Japan, 3Osaka Rosai Hospital, Sakai, Japan, 4Fukui Cardiovascular Center, Department of Cardiology, Fukui, Japan, 5Epworth Hospital, Melbourne, Australia, 6Abbott, Minneapolis, USA
