Experience with permanent pacing in patients with bicaval prostheses remains extremely limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Summary<\/jats:title>\n                    <jats:p>An 83\u2010year\u2010old woman with chronic obstructive pulmonary disease, permanent atrial fibrillation, transfusion\u2010dependent anemia, prior non\u2010ST elevation myocardial infarction, and previous MitraClip implantation for severe mitral regurgitation presented with advanced right\u2010sided heart failure and massive functional TR due to a 17\u00a0mm coaptation gap. Transcatheter tricuspid edge\u2010to\u2010edge repair was not feasible, and she underwent transcatheter bicaval system implantation with two nitinol stent\u2010mounted bioprostheses in the superior and inferior vena cava, resulting in marked symptomatic improvement. Ten months later, she developed symptomatic bradycardia requiring permanent pacing. A single\u2010chamber pacemaker was successfully implanted via the left subclavian vein after venography confirmed safe drainage of the left brachiocephalic vein into the superior vena cava, allowing safe passage of the pacing lead through the prosthetic stent struts. Electrical parameters were excellent, and 10\u2010month follow\u2010up confirmed stable function without lead or valve damage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This is, to our knowledge, the first published report of successful left\u2010sided pacemaker implantation through a tricuspid bicaval prosthesis. Alternative pacing strategies, including conduction system pacing and leadless pacemakers, were carefully considered but deemed unsuitable because of anatomical and clinical constraints. Our case demonstrates that left\u2010sided implantation can be performed safely when venographic anatomy allows. Careful pre\u2010procedural imaging and meticulous lead navigation are essential to ensure prosthesis integrity and durable pacing performance.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/pace.70346","type":"journal-article","created":{"date-parts":[[2026,7,8]],"date-time":"2026-07-08T06:59:48Z","timestamp":1783493988000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["First Report of Left\u2010Sided Transvenous Pacemaker Implantation Through a Bicaval TricValve Prosthesis"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-8948-0934","authenticated-orcid":false,"given":"Pasquale","family":"Spadaro","sequence":"first","affiliation":[{"name":"Cardiology Unit \u201cSan Paolo\u201d Hospital  Napoli Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pietro","family":"Ricciardi","sequence":"additional","affiliation":[{"name":"Marzano Group  Avellino Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Massimo","family":"Cavallaro","sequence":"additional","affiliation":[{"name":"Cardiology Unit \u201cSan Paolo\u201d Hospital  Napoli Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincenzo","family":"Martino","sequence":"additional","affiliation":[{"name":"Cardiology Unit \u201cSan Paolo\u201d Hospital  Napoli Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernardino","family":"Tuccillo","sequence":"additional","affiliation":[{"name":"Cardiology Department Ospedale del Mare  Napoli Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,7]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2023.10.043"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2025.06.023"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2022.05.022"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/euaa180"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.25270\/jic\/24.00180"}],"container-title":["Pacing and Clinical Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.70346","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/pace.70346","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.70346","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,8]],"date-time":"2026-07-08T06:59:48Z","timestamp":1783493988000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/pace.70346"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,7]]},"references-count":5,"alternative-id":["10.1111\/pace.70346"],"URL":"https:\/\/doi.org\/10.1111\/pace.70346","archive":["Portico"],"relation":{},"ISSN":["0147-8389","1540-8159"],"issn-type":[{"value":"0147-8389","type":"print"},{"value":"1540-8159","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,7]]},"assertion":[{"value":"2026-02-03","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-23","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-07","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"pace.70346"}}
