This study aims to assess the clinical feasibility and accuracy of high\u2010density electroanatomical mapping of various RA arrhythmias.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>Electroanatomical maps of the RA (35 partial and 24 complete) were created in 23 patients using a novel mini\u2010basket catheter with 64 electrodes and automatic electrogram annotation. Median acquisition time was 6:43 minutes (0:39\u201323:05 minutes) with shorter times for partial (4.03 \u00b1 4.13 minutes) than for complete maps (9.41 \u00b1 4.92 minutes). During mapping 3,236 (710\u201316,306) data points were automatically annotated without manual correction. Maps obtained during sinus rhythm created geometry consistent with CT imaging and demonstrated activation originating at the middle to superior crista terminalis, while maps during CS pacing showed right atrial activation beginning at the infero\u2010septal region. Activation patterns were consistent with cavotricuspid isthmus\u2010dependent atrial flutter (n = 4), complex reentry tachycardia (n = 1), or ectopic atrial tachycardia (n = 2). His bundle and fractionated potentials in the slow pathway region were automatically detected in all patients. Ablation of the cavotricuspid isthmus (n = 9), the atrio\u2010ventricular node (n = 2), atrial ectopy (n = 2), and the slow pathway (n = 3) was successfully and safely performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>RA mapping with this automatic high\u2010density mapping system is fast, feasible, and safe. It is possible to reproducibly identify propagation of atrial activation during sinus rhythm, various tachycardias, and also complex reentrant arrhythmias.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jce.12852","type":"journal-article","created":{"date-parts":[[2015,10,13]],"date-time":"2015-10-13T02:59:10Z","timestamp":1444705150000},"page":"154-160","source":"Crossref","is-referenced-by-count":34,"title":["Initial Experience With Ultra High\u2010Density Mapping of Human Right Atria"],"prefix":"10.1111","volume":"27","author":[{"given":"ANDREAS","family":"BOLLMANN","sequence":"first","affiliation":[{"name":"Department of Electrophysiology Heart Center  Leipzig Leipzig Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SEBASTIAN","family":"HILBERT","sequence":"additional","affiliation":[{"name":"Department of Electrophysiology Heart Center  Leipzig Leipzig Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SILKE","family":"JOHN","sequence":"additional","affiliation":[{"name":"Department of Electrophysiology Heart Center  Leipzig Leipzig Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JEDRZEJ","family":"KOSIUK","sequence":"additional","affiliation":[{"name":"Department of Electrophysiology Heart Center  Leipzig Leipzig Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GERHARD","family":"HINDRICKS","sequence":"additional","affiliation":[{"name":"Department of Electrophysiology Heart Center  Leipzig Leipzig Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,11,23]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.111.968602"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/euu276"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0972-6292(16)30848-8"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00392-015-0847-y"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12265-015-9610-z"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2011.02120.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.110.957381"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjce.12852","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjce.12852","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.12852","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,1]],"date-time":"2023-10-01T19:35:13Z","timestamp":1696188913000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/jce.12852"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,11,23]]},"references-count":7,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2016,2]]}},"alternative-id":["10.1111\/jce.12852"],"URL":"https:\/\/doi.org\/10.1111\/jce.12852","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,11,23]]}}}
