However, the aggressive manipulation of these materials may lead to potentially severe and threatening complications. We present a case of Turnpike Spiral (Teleflex) tip fracture, which caused an acute occlusion of the proximal right coronary artery. The coronary artery was tortuous and had two heavily calcified lesions in the proximal segment, uncrossable to both small angioplasty balloons and standard microcatheters. After the incarceration of the tip of the Turnpike Spiral in the calcium, it got fractured during the attempt of removing it from the vessel. This led to ST\u2010segment elevation and patient instability. Due to the impossibility of advancing a second guidewire into the true lumen, we decided to proceed to antegrade dissection and re\u2010entry using the scratch\u2010and\u2010go and subintimal tracking and re\u2010entry technique. We placed a guide\u2010extension and we used a Gaia II (Asahi Intecc) to enter the subintimal space and advance over the fractured tip. The wire was exchanged for a Gladius MG (Asahi Intecc), which re\u2010entered the true lumen at the level of the acute margin of the heart. Intravascular ultrasound was used to confirm the re\u2010entry point, and three drug eluting stents were placed. In this way we rapidly restored the flow in the right coronary artery, and we prevented a myocardial infarction.<\/jats:p>","DOI":"10.1002\/ccd.31264","type":"journal-article","created":{"date-parts":[[2024,10,10]],"date-time":"2024-10-10T09:44:28Z","timestamp":1728553468000},"page":"1220-1224","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Microcatheter tip fracture and acute vessel occlusion rescued with subintimal tracking and re\u2010entry:\n                    <i>Move the tip<\/i>"],"prefix":"10.1002","volume":"104","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-0167-4851","authenticated-orcid":false,"given":"Francesco","family":"Giangiacomi","sequence":"first","affiliation":[{"name":"Department of Clinical Sciences and Community Health University of Milan Milan Italy"},{"name":"Department of Cardio\u2010Thoracic\u2010Vascular Diseases Foundation IRCCS Ca' Granda Ospedale Maggiore Policlinico Milan Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luca","family":"Mircoli","sequence":"additional","affiliation":[{"name":"Department of Cardio\u2010Thoracic\u2010Vascular Diseases Foundation IRCCS Ca' Granda Ospedale Maggiore Policlinico Milan Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3121-8400","authenticated-orcid":false,"given":"Gabriele","family":"Tumminello","sequence":"additional","affiliation":[{"name":"Department of Cardio\u2010Thoracic\u2010Vascular Diseases Foundation IRCCS Ca' Granda Ospedale Maggiore Policlinico Milan Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefano","family":"Carugo","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences and Community Health University of Milan Milan Italy"},{"name":"Department of Cardio\u2010Thoracic\u2010Vascular Diseases Foundation IRCCS Ca' Granda Ospedale Maggiore Policlinico Milan Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,10,10]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.4244\/EIJ-D-20-00572"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.carrev.2018.02.012"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jccase.2019.07.007"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cjca.2022.06.026"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.carrev.2020.12.017"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.4244\/EIJ-D-21-01117"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jscai.2022.100348"}],"updated-by":[{"DOI":"10.1002\/ccd.70630","type":"correction","label":"Correction","source":"publisher","updated":{"date-parts":[[2026,4,22]],"date-time":"2026-04-22T00:00:00Z","timestamp":1776816000000}}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.31264","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/ccd.31264","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.31264","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T08:17:29Z","timestamp":1777709849000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.31264"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,10,10]]},"references-count":7,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2024,11]]}},"alternative-id":["10.1002\/ccd.31264"],"URL":"https:\/\/doi.org\/10.1002\/ccd.31264","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,10,10]]},"assertion":[{"value":"2024-07-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-10-02","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-10-10","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
