We were now interested in how these disorders behaved at intermediate follow-up. Methods: All 87 patients who had undergone surgical aortic valve replacement (SAVR) using the rapid deployment Intuity\u2122 Elite prosthesis and were shown to have conduction disorders at the time of hospital discharge were followed up after surgery. These patients\u2019 ECGs were recorded at least 1 year after surgery, and the persistence of the new postoperative conduction disorders was assessed. Results: At hospital discharge, 48.1% of the patients had developed new postoperative conduction disorders, with LBBB being the predominant conduction disturbance (36.5%). At medium-term follow-up (526 days, standard deviation (SD) = 169.6, standard error (SE) = 19.3 days, respectively), 44% of the new LBBB and 50% of the new right bundle branch block (RBBB) had disappeared. There was no new atrio-ventricular block III (AVB III) that occurred. One new pacemaker (PM) was implanted during follow-up because of AVB II Mobitz type II. Conclusions: At medium-term follow-up after the implantation of a rapid deployment Intuity\u2122 Elite aortic valve prosthesis, the number of new postoperative conduction disorders, especially LBBB, has considerably decreased but remains high. The incidence of postoperative AV block III remained stable.<\/jats:p>","DOI":"10.3390\/jcm12052083","type":"journal-article","created":{"date-parts":[[2023,3,7]],"date-time":"2023-03-07T01:43:35Z","timestamp":1678153415000},"page":"2083","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Conduction Disorders after Surgical Aortic Valve Replacement Using a Rapid Deployment Aortic Valve Prosthesis: Medium-Term Follow-Up"],"prefix":"10.3390","volume":"12","author":[{"given":"Christian","family":"Mogilansky","sequence":"first","affiliation":[{"name":"Department of Cardiac Surgery, Klinikum Passau, 94032 Passau, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parwis","family":"Massoudy","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Klinikum Passau, 94032 Passau, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8194-3427","authenticated-orcid":false,"given":"Markus","family":"Czesla","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Klinikum Passau, 94032 Passau, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7340-7472","authenticated-orcid":false,"given":"Robert","family":"Balan","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Klinikum Passau, 94032 Passau, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"581","DOI":"10.1093\/icvts\/ivy307","article-title":"New postoperative conduction abnormalities after the implantation of a rapid-deployment aortic valve prosthesis","volume":"28","author":"Mogilansky","year":"2019","journal-title":"Interact.
