Accessory pathways were the arrhythmic substrate in 252 of the patients (87.8%), the patients having a total of 265 accessory pathways. Atrioventricular nodal re-entry was the cause of tachycardia in 26 patients (9.0%), while atrial flutter was detected in the remaining 9 patients (3.1%). We were able successfully to eliminate the accessory pathway in 236 patients (89%), but 25 patients had recurrent arrhythmias. Ablation proved successful in all cases of atrioventricular node re-entry tachycardia, the slow pathway being ablated in 25 patients, and the fast pathway in only one case. Recurrence of the arrhythmia occurred in three patients (11.5%). We performed a second ablation in these children, all then proving successful. The ablation was successful in all cases of atrial flutter, with one recurrence (11.1%). Overall, therefore, ablation was immediately successful in 271 patients (94.4%), with a recurrence of the arrhythmia in 29 cases (10.7%). The incidence of serious complications was 2.09% There was one late death due to infective endocarditis, 3 patients suffered complete heart block, 1 had mild mitral regurgitation, and 1 patient developed an haematoma in the groin. We conclude that radiofrequency catheter ablation can now be considered a standard option for the management of paroxysmal supraventricular tachycardias in children and young adults.<\/jats:p>","DOI":"10.1017\/s1047951100009689","type":"journal-article","created":{"date-parts":[[2008,8,31]],"date-time":"2008-08-31T20:03:34Z","timestamp":1220213014000},"page":"376-383","source":"Crossref","is-referenced-by-count":12,"title":["Radiofrequency catheter ablation for the treatment of supraventricular tachycardias in children and adolescents"],"prefix":"10.1017","volume":"10","author":[{"given":"Pedro","family":"Iturralde","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu\u00eds","family":"Col\u00edn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergio","family":"Kershenovich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milton E.","family":"Guevara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Argelia","family":"Medeiros","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alfonso","family":"Buendia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fause","family":"Attie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2008,8,19]]},"reference":[{"key":"S1047951100009689_ref040","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1993.tb01277.x"},{"key":"S1047951100009689_ref039","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(93)90376-C"},{"key":"S1047951100009689_ref037","doi-asserted-by":"publisher","DOI":"10.1016\/S0033-0620(05)80015-5"},{"key":"S1047951100009689_ref034","first-page":"1","article-title":"Right coronary epicardial mapping improves accessory pathway catheter ablation success","volume":"80","author":"Swarts","year":"1989","journal-title":"Circulation"},{"key":"S1047951100009689_ref030","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(78)90863-9"},{"key":"S1047951100009689_ref028","doi-asserted-by":"crossref","first-page":"930","DOI":"10.1542\/peds.89.5.930","article-title":"Radiofrequency current for catheter ablation of accessory atrioventricular connections in children and adolescents","volume":"89","author":"Schluter","year":"1992","journal-title":"Pediatrics"},{"key":"S1047951100009689_ref027","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(97)00736-4"},{"key":"S1047951100009689_ref026","doi-asserted-by":"publisher","DOI":"10.3928\/0090-4481-19910701-12"},{"key":"S1047951100009689_ref025","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(91)90656-T"},{"key":"S1047951100009689_ref024","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(93)90087-H"},{"key":"S1047951100009689_ref022","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(85)80179-0"},{"key":"S1047951100009689_ref020","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(97)70037-4"},{"key":"S1047951100009689_ref019","doi-asserted-by":"crossref","first-page":"28","DOI":"10.1017\/S1047951100010830","article-title":"Catheter ablation in children with supraventricular tachycardia mediated by accessory pathways.
