The purpose of this prospective study was to assess AVB shortly after successful cryoablation of AVNRT in children.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A 6\u2010mm\u2010tip cryocatheter was used in 39 procedures. An 8\u2010mm\u2010tip catheter was used in 11 procedures. Twelve\u2010lead electrocardiograms (ECGs) and 24\u2010hour ambulatory ECGs were performed 24 hours prior to the procedure and immediately following the procedure. All procedures were done using the EnSite system (St. Jude Medical, St. Paul, MN, USA) without fluoroscopy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Although nine (18%) patients developed variable degrees of transient AVB during the procedure, all of them had normal atrioventricular (AV) conduction at the end of the procedure and did not require any intervention. Four of these patients had variable degrees of transient AVB following the procedure despite having normal AV conduction at the end of the procedure. One developed Mobitz type I AVB, which lasted for 11.5 hours, and the other three experienced 2:1 AVB, which lasted for 2, 8, and 24 hours, respectively. All patients had complete resolution of the AVB, which was also documented with the 24\u2010hour ambulatory ECGs after the procedure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Early transient AVB can develop following AVNRT cryoablation even if AV conduction is normal at the end of the procedure. Despite the transient AVB in the initial 24 hours after the procedure in some cases, there is no evidence for ongoing AV nodal dysfunction.<\/jats:p><\/jats:sec>","DOI":"10.1111\/pace.12347","type":"journal-article","created":{"date-parts":[[2014,1,28]],"date-time":"2014-01-28T19:46:01Z","timestamp":1390938361000},"page":"712-716","source":"Crossref","is-referenced-by-count":5,"title":["Assessment of Atrioventricular Conduction Following Cryoablation of Atrioventricular Nodal Reentrant Tachycardia in Children"],"prefix":"10.1111","volume":"37","author":[{"given":"NESLIHAN","family":"KIPLAPINAR","sequence":"first","affiliation":[{"name":"Division of Pediatric Cardiology Mehmet Akif Ersoy Cardiovascular Research and Training Hospital  Istanbul Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YAKUP","family":"ERGUL","sequence":"additional","affiliation":[{"name":"Division of Pediatric Cardiology Mehmet Akif Ersoy Cardiovascular Research and Training Hospital  Istanbul Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CELAL","family":"AKDENIZ","sequence":"additional","affiliation":[{"name":"Pediatric Arrhythmia Center Mehmet Akif Ersoy Cardiovascular Research and Training Hospital  Istanbul Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MURAT","family":"SAYGI","sequence":"additional","affiliation":[{"name":"Division of Pediatric Cardiology Mehmet Akif Ersoy Cardiovascular Research and Training Hospital  Istanbul Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ISA","family":"OZYILMAZ","sequence":"additional","affiliation":[{"name":"Division of Pediatric Cardiology Mehmet Akif Ersoy Cardiovascular Research and Training Hospital  Istanbul Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ENES E.","family":"GUL","sequence":"additional","affiliation":[{"name":"Division of Pediatric Cardiology Istanbul Medipol University  Istanbul Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"VOLKAN","family":"TUZCU","sequence":"additional","affiliation":[{"name":"Pediatric Arrhythmia Center Mehmet Akif Ersoy Cardiovascular Research and Training Hospital  Istanbul Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,1,28]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8167.2002.01082.x"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.2007.00824.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2004.12.048"},{"key":"e_1_2_6_5_1","first-page":"182","article-title":"Cryoablation: Better catheter stability compared to RF ablation","volume":"6","author":"Tuzcu V","year":"2006","journal-title":"Anadolu Kardiyol Derg"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.2010.02858.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000058706.82623.A1"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.99.2.262"},{"key":"e_1_2_6_9_1","doi-asserted-by":"crossref","first-page":"1644","DOI":"10.1093\/eurheartj\/14.12.1644","article-title":"The Multicentre European Radiofrequency Survey (MERFS): Complications of radiofrequency catheter ablation of arrhythmias.
