Group A had a medical history of a Mustard or Senning operation, whereas group B had undergone total cavopulmonary connection. A total of 26 tachycardias were treated in 17 procedures (median cycle length of 280 ms). Group A patients had more inducible SVTs than group B, and all index SVTs were located in the remainder of the morphological right atrium in all but 1 patient. Retrograde access through the aorta was performed and led to successful ablation, using magnetic navigation with a very low total radiation exposure (median of 3.8 minutes in group A versus 5.9 minutes in group B). Only 1 of 13 patients continued to have short-lasting SVTs despite 3 ablation procedures during a median follow-up time of &gt;200 days.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Remote-controlled catheter ablation by magnetic navigation in combination with accurate 3D image integration allowed safe and successful elimination of SVTs, using an exclusively retrograde approach, resulting in low radiation exposure for patients after intra-atrial baffle procedures (Mustard, Senning, or total cavopulmonary connection).<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circep.111.962993","type":"journal-article","created":{"date-parts":[[2011,11,8]],"date-time":"2011-11-08T08:09:54Z","timestamp":1320739794000},"page":"131-139","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":76,"title":["Remote-Controlled Magnetic Navigation and Ablation With 3D Image Integration as an Alternative Approach in Patients With Intra-Atrial Baffle Anatomy"],"prefix":"10.1161","volume":"5","author":[{"given":"Sabine","family":"Ernst","sequence":"first","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonya V.","family":"Babu-Narayan","sequence":"additional","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Keegan","sequence":"additional","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irina","family":"Horduna","sequence":"additional","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Lyne","sequence":"additional","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janice","family":"Till","sequence":"additional","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip J.","family":"Kilner","sequence":"additional","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dudley","family":"Pennell","sequence":"additional","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael L.","family":"Rigby","sequence":"additional","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"Gatzoulis","sequence":"additional","affiliation":[{"name":"From the Royal Brompton and Harefield NHS Foundation Trust and Imperial College London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejcts.2006.08.025"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.105.592410"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951104003063"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2003.12.066"},{"key":"e_1_3_3_6_2","first-page":"187","article-title":"Risk factors for arrhythmia and death after Mustard operation for simple transposition of the great arteries","volume":"84","author":"Gewillig M","year":"1991","unstructured":"Gewillig M, Cullen S, Mertens B, Lesaffre E, Deanfield J .
