Addition of electroanatomical mapping may further reduce dose. Methods:<\/jats:italic> From 6\/11 to 4\/12, a novel ALARA protocol was utilised for all patients undergoing supraventricular tachycardia ablation, including low frame rates (2\u20133 frames\/second), low fluoro dose\/frame (6\u201318 nGy\/frame), and other techniques to reduce fluoroscopy (ALARA). From 6\/12 to 3\/13, use of CARTO\u00ae<\/jats:sup> 3 (C3) with \u201cfast anatomical mapping\u201d (ALARA+C3) was added to the ALARA protocol. Intravascular echo was not utilised. Demographics, procedural, and radiation data were analysed and compared between the two protocols. Results:<\/jats:italic> A total of 75 patients were included: 42 ALARA patients, and 33 ALARA+C3 patients. Patient demographics were similar between the two groups. The acute success rate in ALARA was 95%, and 100% in ALARA+C3; no catheterisation-related complications were observed. Procedural time was 125.7 minutes in the ALARA group versus 131.4 in ALARA+C3 (p=0.36). Radiation doses were significantly lower in the ALARA+C3 group with a mean air Kerma in ALARA+C3 of 13.1\u00b128.3 mGy (SD) compared with 93.8\u00b1112 mGy in ALARA (p<0.001). Mean dose area product was 92.2\u00b1179 uGym2 in ALARA+C3 compared with 584\u00b1687 uGym2 in ALARA (p<0.001). Of the 33 subjects (42%) in the ALARA+C3 group, 14 received \u2a7d1 mGy exposure. The ALARA+C3 dosages are the lowest reported for a combined electroanatomical\u2013fluoroscopy technique. Conclusions:<\/jats:italic> Addition of CARTO\u00ae<\/jats:sup> 3 to ALARA protocols markedly reduced radiation exposure to young people undergoing supraventricular tachycardia ablation while allowing for equivalent procedural efficacy and safety.<\/jats:p>","DOI":"10.1017\/s1047951114001474","type":"journal-article","created":{"date-parts":[[2014,8,26]],"date-time":"2014-08-26T03:32:32Z","timestamp":1409023952000},"page":"963-968","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":25,"title":["Reducing patient radiation exposure during paediatric SVT ablations: use of CARTO\u00ae<\/sup> 3 in concert with \u201cALARA\u201d principles profoundly lowers total dose"],"prefix":"10.1017","volume":"25","author":[{"given":"Robert H.","family":"Pass","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory G.","family":"Gates","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura A.","family":"Gellis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lynn","family":"Nappo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott R.","family":"Ceresnak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2014,8,22]]},"reference":[{"key":"S1047951114001474_ref11","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.24602"},{"key":"S1047951114001474_ref10","doi-asserted-by":"publisher","DOI":"10.1111\/pace.12124"},{"key":"S1047951114001474_ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2008.08.009"},{"key":"S1047951114001474_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(97)70037-4"},{"key":"S1047951114001474_ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2010.12.022"},{"key":"S1047951114001474_ref6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.2008.00987.x"},{"key":"S1047951114001474_ref9","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-011-9956-1"},{"key":"S1047951114001474_ref12","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.2005.063909"},{"key":"S1047951114001474_ref1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8167.2004.03645.x"},{"key":"S1047951114001474_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(94)71456-1"},{"key":"S1047951114001474_ref7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.2010.02952.x"},{"key":"S1047951114001474_ref3","doi-asserted-by":"publisher","DOI":"10.1016\/S0887-2171(02)90014-4"}],"container-title":["Cardiology in the Young"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1047951114001474","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,20]],"date-time":"2019-04-20T20:35:16Z","timestamp":1555792516000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1047951114001474\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,8,22]]},"references-count":12,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2015,6]]}},"alternative-id":["S1047951114001474"],"URL":"https:\/\/doi.org\/10.1017\/s1047951114001474","relation":{},"ISSN":["1047-9511","1467-1107"],"issn-type":[{"value":"1047-9511","type":"print"},{"value":"1467-1107","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,8,22]]},"assertion":[{"value":"\u00a9 Cambridge University Press 2014\u00a0","name":"license","label":"License","group":{"name":"copyright_and_licensing","label":"Copyright and Licensing"}}]}}
