The introduction of the leadless pacemaker has reduced the risk for this complication.

The device had been implanted at the base of the right ventricular outflow tract two weeks after a tricuspid valve replacement for the treatment of a Staphylococcus aureus native tricuspid valve endocarditis after intravenous drug abuse, complicated by a third-degree AV block. Echocardiography upon admission showed a large vegetation on the bioprosthetic tricuspid valve with dislocation of the leadless pacemaker. Interrogation of the device showed loss of atrial mechanical sensing, ventricular sensing and pacing capture. Blood cultures showed recurrence of S. aureus bacteraemia and confirmed the diagnosis of bioprosthetic valve and possible device-related endocarditis. Device dislocation and tine fracture were confirmed by cinefluoroscopy. Because of refractory septic and cardiogenic shock and ongoing drug abuse, the patient was deemed ineligible for surgery and palliative care was initiated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Device dislodgement due to tine fracture is a rare but serious complication following leadless pacemaker implantation. Infective endocarditis with large vegetations can interact with leadless pacemakers implanted on the high septum. Clinicians should remain vigilant of endocarditis-related complications, even in the setting of leadless pacemaker devices.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytaf480","type":"journal-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T12:05:01Z","timestamp":1758283501000},"source":"Crossref","is-referenced-by-count":1,"title":["Leadless pacemaker tine fracture and dislodgement in infective tricuspid valve endocarditis: a case report"],"prefix":"10.1093","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-4708-2866","authenticated-orcid":false,"given":"Oscar","family":"Rommens","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Sciences, University Hospitals Leuven , Herestraat 49, Leuven 3000 ,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5469-9609","authenticated-orcid":false,"given":"Rik","family":"Willems","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences, University Hospitals Leuven , Herestraat 49, Leuven 3000 ,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3077-0914","authenticated-orcid":false,"given":"Gabor","family":"Voros","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences, University Hospitals Leuven , Herestraat 49, Leuven 3000 ,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7580-9718","authenticated-orcid":false,"given":"Pascal","family":"Frederiks","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences, University Hospitals Leuven , Herestraat 49, Leuven 3000 ,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2173-1035","authenticated-orcid":false,"given":"Christophe","family":"Garweg","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Sciences, University Hospitals Leuven , Herestraat 49, Leuven 3000 ,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,9,22]]},"reference":[{"key":"2025111813173665500_ytaf480-B1","doi-asserted-by":"crossref","first-page":"3427","DOI":"10.1093\/eurheartj\/ehab364","article-title":"2021 ESC guidelines on cardiac pacing and cardiac resynchronization therapy","volume":"42","author":"Glikson","year":"2021","journal-title":"Eur Heart J"},{"key":"2025111813173665500_ytaf480-B2","doi-asserted-by":"crossref","first-page":"1241","DOI":"10.1093\/eurheartj\/ehae101","article-title":"Leadless pacemakers at 5-year follow-up: the Micra transcatheter pacing system post-approval registry","volume":"45","author":"El-Chami","year":"2024","journal-title":"Eur Heart J"},{"key":"2025111813173665500_ytaf480-B3","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1016\/j.hroo.2023.11.018","article-title":"Leadless pacemaker tine damage and fracture: novel complications of a novel device fixation mechanism","volume":"5","author":"Maclean","year":"2024","journal-title":"Heart Rhythm O2"},{"key":"2025111813173665500_ytaf480-B4","first-page":"37","article-title":"Lost but not lost\u2014embolization of a leadless pacemaker to the pulmonary artery with consecutive endovascular recovery","volume":"8","author":"Barbieri","year":"2021","journal-title":"J Cardiovasc Dev Dis"},{"key":"2025111813173665500_ytaf480-B5","doi-asserted-by":"crossref","first-page":"ii26","DOI":"10.1093\/eurheartjsupp\/suae119","article-title":"Long-term management of leadless pacemakers","volume":"27","author":"Andreae","year":"2025","journal-title":"Eur Heart J Suppl"},{"key":"2025111813173665500_ytaf480-B6","doi-asserted-by":"crossref","first-page":"euae256","DOI":"10.1093\/europace\/euae256","article-title":"Transcatheter non-acute retrieval of the tine-based leadless ventricular pacemaker","volume":"26","author":"Funasako","year":"2024","journal-title":"Europace"},{"key":"2025111813173665500_ytaf480-B7","first-page":"926","article-title":"Micra leadless pacemaker extraction using aveir retrieval catheter\u2014initial experience in Poland","volume":"83","author":"Tajstra","year":"2025","journal-title":"Kardiol Pol"},{"key":"2025111813173665500_ytaf480-B8","doi-asserted-by":"crossref","first-page":"1393","DOI":"10.1016\/j.hrthm.2020.03.019","article-title":"Leadless pacemakers reduce risk of device-related infection: review of the potential mechanisms","volume":"17","author":"El-Chami","year":"2020","journal-title":"Heart Rhythm"},{"key":"2025111813173665500_ytaf480-B9","doi-asserted-by":"crossref","first-page":"1671","DOI":"10.1111\/jce.14076","article-title":"Safety and efficacy of leadless pacemaker retrieval","volume":"30","author":"Li","year":"2019","journal-title":"J Cardiovasc Electrophysiol"}],"container-title":["European Heart Journal -
