Of the 128 patients, 90 (70%) had return of atrioventricular node function, and 38 (30%) had pacemaker placement. Of the 38 patients who underwent pacemaker placement, 6 (15.8%) had recovery of atrioventricular node function noted on long-term follow-up. Median time from onset of heart block to late atrioventricular node recovery was 13 days (Interquartile range: 5 \u2013 117). Patients with single-ventricle physiology (p = 0.04), greater weight (p = 0.03), and shorter cardiopulmonary bypass time (p = 0.015) were more likely to have recovery. The use of post-operative steroids was similar between all groups (p = 0.445). Infectious or wound complications were similar between pacemaker groups (p = 1).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1047951122002025_as4\">\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Two per cent of patients who underwent congenital cardiac surgery developed post-operative heart block, and 0.6% underwent pacemaker placement. Early recovery of atrioventricular node was associated with greater weight at the time of surgery, single-ventricle physiology, and shorter cardiopulmonary bypass time. Late recovery of atrioventricular node conduction following pacemaker placement occurred in 15.8% of patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1017\/s1047951122002025","type":"journal-article","created":{"date-parts":[[2022,7,29]],"date-time":"2022-07-29T01:12:04Z","timestamp":1659057124000},"page":"1150-1156","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":9,"title":["Incidence and recovery of post-surgical heart block in children following cardiac surgery"],"prefix":"10.1017","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7665-0294","authenticated-orcid":false,"given":"Rohit","family":"Madani","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"Aronoff","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Posey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohua","family":"Basu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tawanda","family":"Zinyandu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Chai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Whitehill","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin O.","family":"Maher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asaad G.","family":"Beshish","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2022,7,29]]},"reference":[{"key":"S1047951122002025_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2012.05.012"},{"key":"S1047951122002025_ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2018.06.038"},{"key":"S1047951122002025_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2016.03.081"},{"key":"S1047951122002025_ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2016.10.078"},{"key":"S1047951122002025_ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2014.12.098"},{"key":"S1047951122002025_ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2021.07.051"},{"key":"S1047951122002025_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(98)00375-0"},{"key":"S1047951122002025_ref3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2012.02385.x"},{"key":"S1047951122002025_ref11","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.38.11.1217"},{"key":"S1047951122002025_ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2018.09.142"},{"key":"S1047951122002025_ref10","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(03)00198-3"},{"key":"S1047951122002025_ref12","doi-asserted-by":"publisher","DOI":"10.1023\/A:1015379903936"},{"key":"S1047951122002025_ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2016.11.010"}],"container-title":["Cardiology in the Young"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1047951122002025","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,15]],"date-time":"2023-09-15T09:14:41Z","timestamp":1694769281000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1047951122002025\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,7,29]]},"references-count":13,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2023,7]]}},"alternative-id":["S1047951122002025"],"URL":"https:\/\/doi.org\/10.1017\/s1047951122002025","relation":{},"ISSN":["1047-9511","1467-1107"],"issn-type":[{"value":"1047-9511","type":"print"},{"value":"1467-1107","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,7,29]]},"assertion":[{"value":"\u00a9 The Author(s), 2022.
