The origin of ventricular tachycardia was in the right ventricular outflow tract in nine patients, in the left ventricle in six, near the bundle of His\/right bundle branch in one, and in the left aortic cusp in one. The mean procedure and fluoroscopy times were 169.3 \u00b1 43.2 minutes and 8 \u00b1 10.8 minutes, respectively. No fluoroscopy was used in six patients. The mean radiation exposure was 33.1 \u00b1 56.4 mGy. Acute success was achieved in 14 patients (82%). The focus of ventricular tachycardia was epicardial in two failed procedures. During a mean follow-up of 8.5 \u00b1 7.6 months, ventricular tachycardia recurred in three patients, two of whom underwent a second procedure. Except for one patient who developed transient right bundle branch block, no complications were seen.<\/jats:p><\/jats:sec><jats:sec id=\"S1047951113001364_abs4\" sec-type=\"conclusion\"><jats:title>Conclusion<\/jats:title><jats:p>Catheter ablation of idiopathic ventricular tachycardia in children can be performed safely and effectively with low fluoroscopy exposure using the EnSite NavX system.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s1047951113001364","type":"journal-article","created":{"date-parts":[[2013,9,10]],"date-time":"2013-09-10T22:30:19Z","timestamp":1378852219000},"page":"886-892","source":"Crossref","is-referenced-by-count":16,"title":["Catheter ablation of idiopathic ventricular tachycardia in children using the EnSite NavX system with\/without fluoroscopy"],"prefix":"10.1017","volume":"24","author":[{"given":"Isa","family":"Ozyilmaz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yakup","family":"Ergul","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Celal","family":"Akdeniz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erkut","family":"Ozturk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ibrahim C.","family":"Tanidir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Volkan","family":"Tuzcu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2013,9,10]]},"reference":[{"key":"S1047951113001364_ref13","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-006-0187-1"},{"key":"S1047951113001364_ref7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.2007.00701.x"},{"key":"S1047951113001364_ref4","doi-asserted-by":"publisher","DOI":"10.1007\/s00059-009-3247-0"},{"key":"S1047951113001364_ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2010.02.031"},{"key":"S1047951113001364_ref2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.95.6.1611"},{"key":"S1047951113001364_ref8","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.109.872093"},{"key":"S1047951113001364_ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-011-9956-1"},{"key":"S1047951113001364_ref10","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-006-0194-2"},{"key":"S1047951113001364_ref5","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.2007.00702.x"},{"key":"S1047951113001364_ref9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2008.01277.x"},{"key":"S1047951113001364_ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2004.05.009"},{"key":"S1047951113001364_ref12","first-page":"892","article-title":"ACC expert consensus document.
