Currently, clinical experience with left bundle branch pacing (LBBP) in such special patients remains extremely limited. This article reports a case of a 73-year-old male patient diagnosed with mirror-image dextrocardia complicated by advanced heart failure and complete left bundle branch block (CLBBB). Through preoperative mirror-image adaptation of\n                    <jats:italic>electrocardiogram<\/jats:italic>\n                    and digital subtraction angiography (DSA) systems, combined with reverse personalized heat shaping of the delivery sheath during the procedure, we successfully completed the implantation of an LBBP-based cardiac resynchronization therapy defibrillator (CRT-D). This case is extremely rare and provides valuable insights for the management of such patients.\n                  <\/jats:p>","DOI":"10.3389\/fcvm.2026.1834563","type":"journal-article","created":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T05:41:56Z","timestamp":1780983716000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Implantation of cardiac resynchronization therapy defibrillator with left bundle branch pacing in a patient with mirror-image dextrocardia: a case report"],"prefix":"10.3389","volume":"13","author":[{"given":"Hongwei","family":"Yi","sequence":"first","affiliation":[{"name":"Department of Cardiology, Wuhan Asia Heart Hospital","place":["Wuhan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Wuhan Asia Heart Hospital","place":["Wuhan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongwei","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Wuhan Asia Heart Hospital","place":["Wuhan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Bao","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Wuhan Asia Heart Hospital","place":["Wuhan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,6,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2437","DOI":"10.2147\/IJGM.S295444","article-title":"Situs inversus totalis: a clinical review","volume":"15","author":"Eitler","year":"2022","journal-title":"Int J Gen Med"},{"key":"B2","doi-asserted-by":"publisher","first-page":"1070","DOI":"10.1093\/europace\/eut206","article-title":"2013 ESC guidelines on cardiac pacing and cardiac resynchronization therapy: the task force on cardiac pacing and resynchronization therapy of the European Society of Cardiology (ESC).
