We aim to determine whether G2 valves reduce these specific complications and thereby improve patient outcomes compared with G1. Methods: From February 2015 to September 2022, 1468 patients underwent TAVR at the university clinic in Kiel. After applying exclusion criteria, a final cohort of 1182 patients were analysed. Among these, 782 patients underwent TAVR with G1, whereas 400 underwent TAVR with G2. The primary study endpoints were the occurrence of new CD and PPMI within 30 days post-procedure. The secondary endpoints included diverse post-TAVR events as defined by the safety criteria of Valve Academic Research Consortium 3 (VARC III). A statistical analysis compared outcomes between the G1 and G2 groups. Results: Out of 1182 patients, 12.1% required PPMI within 30 days. Rates showed no statistical difference between G2 and G1 for PPMI (10.3% vs. 13.0%, IPTW-weighted p = 0.31) or CD (15.3% vs. 21.48%, IPTW-weighted p = 0.08). Among G2, the Sapien 3 Ultra valve had the lowest PPMI rate (4.8%). Overall, G2 and G1 had similar post-procedural and 30-day mortality rates. Conclusion: G2 valves may reduce post-procedure CD, but the difference is not statistically significant. Differences between specific valve types\u2014such as the Sapien 3 Ultra\u2019s lower rates\u2014are notable, but overall, PPMI and safety profiles remain similar between G1 and G2. Patient and procedural factors still play a significant role. Careful valve and patient selection is essential, and ongoing research will guide further improvements.<\/jats:p>","DOI":"10.3390\/medsci13040296","type":"journal-article","created":{"date-parts":[[2025,12,2]],"date-time":"2025-12-02T15:31:46Z","timestamp":1764689506000},"page":"296","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Incidence of Post-Procedural Conduction Disturbances and Rates of Permanent Pacemaker Implantation in Older and Newer Generations of Transcatheter Aortic Heart Valves"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8433-6959","authenticated-orcid":false,"given":"Mostafa","family":"Salem","sequence":"first","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"},{"name":"Department of Internal Medicine III, Cardiology and Angiology, University Hospital Schleswig-Holstein Kiel Germany, Arnold-Heller-Str. 3, Haus K3, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philipp","family":"Laing","sequence":"additional","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Insa","family":"K\u00fchling-thees","sequence":"additional","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wiebke","family":"Kasper","sequence":"additional","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4547-9260","authenticated-orcid":false,"given":"Jakob","family":"Voran","sequence":"additional","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"},{"name":"German Center for Cardiovascular Research (DZHK), Partner Site Hamburg\/Lu\u0308beck\/Kiel, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hatim","family":"Seoudy","sequence":"additional","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"},{"name":"German Center for Cardiovascular Research (DZHK), Partner Site Hamburg\/Lu\u0308beck\/Kiel, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafael","family":"Rangel","sequence":"additional","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johanne","family":"Frank","sequence":"additional","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"},{"name":"German Center for Cardiovascular Research (DZHK), Partner Site Hamburg\/Lu\u0308beck\/Kiel, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7561-075X","authenticated-orcid":false,"given":"Derk","family":"Frank","sequence":"additional","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"},{"name":"German Center for Cardiovascular Research (DZHK), Partner Site Hamburg\/Lu\u0308beck\/Kiel, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammed","family":"Saad","sequence":"additional","affiliation":[{"name":"Klinik fu\u0308r Innere Medizin III, Schwerpunkte Kardiologie, Angiologie und Intensivmedizin, Universita\u0308tsklinikum Schleswig-Holstein, 24105 Kiel, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1609","DOI":"10.1056\/NEJMoa1514616","article-title":"Transcatheter or surgical aortic-valve replacement in intermediate-risk patients","volume":"374","author":"Leon","year":"2016","journal-title":"N.
