However, its use is still associated with some risks and complications. Here, we report a device fracture as a rare complication that occurred during the device extraction a few days after the initial insertion.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>A 74-year-old man with cardiogenic shock due to acute non-ST-segment elevation myocardial infarction presented to our hospital, and he was transferred to the cath lab for emergency percutaneous coronary intervention (PCI). An Impella CP pump was inserted without any complication prior to PCI. After successful PCI, the patient was transferred to the intensive care unit with device left for continued haemodynamic support. After 3 days, as the patient\u2019s condition remarkably improved, we tried to remove the device. However, a persistent mechanical resistance hindered the further catheter retraction; therefore, a decision was made to remove the catheter under fluoroscopy. Indeed, the fluoroscopy revealed a broken distal part of the pump at the level of the ascending aorta. The retained catheter tip was eventually snared with a snare catheter and removed without any complication.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>An Impella microaxial pump may improve the overall outcome by providing haemodynamic support in critically ill patients. However, its application is not without complications. Intravascular device tip fracture, as demonstrated in this case report, is a rarely reported complication. The use of a snare catheter can be an option in retrieving a broken pump.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytac335","type":"journal-article","created":{"date-parts":[[2022,8,16]],"date-time":"2022-08-16T04:07:31Z","timestamp":1660622851000},"source":"Crossref","is-referenced-by-count":2,"title":["Device fracture as a potential complication of a left ventricular microaxial pump catheter: a case report"],"prefix":"10.1093","volume":"6","author":[{"given":"Mirza","family":"Mutallimov","sequence":"first","affiliation":[{"name":"Department of Internal Medicine II, Klinikum Idar-Oberstein , 55743 Idar-Oberstein , Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fikret","family":"Er","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine I, Klinikum G\u00fctersloh , Reckenberger Str 19, 33332 G\u00fctersloh , Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8968-5808","authenticated-orcid":false,"given":"Natig","family":"Gassanov","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Klinikum Idar-Oberstein , 55743 Idar-Oberstein , Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,8,16]]},"reference":[{"key":"2022082315171323300_ytac335-B1","doi-asserted-by":"crossref","first-page":"943","DOI":"10.1097\/CCM.0000000000004915","article-title":"Early Impella support in postcardiac arrest cardiogenic shock complicating acute myocardial infarction improves short- and long-term survival","volume":"49","author":"Chatzis","year":"2021","journal-title":"Crit Care Med"},{"key":"2022082315171323300_ytac335-B2","doi-asserted-by":"crossref","first-page":"338","DOI":"10.1177\/2048872618805486","article-title":"Real-life use of left ventricular circulatory support with Impella in cardiogenic shock after acute myocardial infarction: 12 years AMC experience","volume":"8","author":"Ouweneel","year":"2019","journal-title":"Eur Heart J Acute Cardiovasc Care"},{"key":"2022082315171323300_ytac335-B3","doi-asserted-by":"crossref","first-page":"363","DOI":"10.1186\/s13054-015-1073-8","article-title":"Management and outcome of patients supported with Impella 5.0 for refractory cardiogenic shock","volume":"19","author":"Gaudard","year":"2015","journal-title":"Crit Care"},{"key":"2022082315171323300_ytac335-B4","doi-asserted-by":"crossref","first-page":"835","DOI":"10.21037\/atm.2020.03.152","article-title":"Complications associated with mechanical circulatory support","volume":"8","author":"Ali","year":"2020","journal-title":"Ann Transl Med"},{"key":"2022082315171323300_ytac335-B5","doi-asserted-by":"crossref","first-page":"2568","DOI":"10.1016\/j.jcin.2016.09.032","article-title":"Impella 5.0 fracture and transcatheter retrieval","volume":"9","author":"Bhamidipati","year":"2016","journal-title":"JACC Cardiovasc Interv"},{"key":"2022082315171323300_ytac335-B6","doi-asserted-by":"crossref","first-page":"584","DOI":"10.1016\/j.hrcr.2017.08.007","article-title":"Intravascular fracture of the Impella device during removal","volume":"3","author":"Castro","year":"2017","journal-title":"HeartRhythm Case Rep"},{"key":"2022082315171323300_ytac335-B7","doi-asserted-by":"crossref","first-page":"1494","DOI":"10.1016\/j.jaccas.2021.06.041","article-title":"Retrieval of entrapped catheter-mounted axial flow pump from mitral subvalvular apparatus using a snare catheter","volume":"3","author":"Elsherif","year":"2021","journal-title":"JACC Case Rep"},{"key":"2022082315171323300_ytac335-B8","first-page":"550","article-title":"The successful withdrawal of a migrated central venous catheter","volume":"3","author":"Zamani","year":"2012","journal-title":"Caspian J Intern Med"},{"key":"2022082315171323300_ytac335-B9","doi-asserted-by":"crossref","first-page":"e15","DOI":"10.1016\/j.jcin.2016.11.012","article-title":"First experience with successful percutaneous retrieval of retained-fractured Impella device","volume":"10","author":"Saleh","year":"2017","journal-title":"JACC Cardiovasc Interv"},{"key":"2022082315171323300_ytac335-B10","doi-asserted-by":"crossref","first-page":"1259","DOI":"10.2214\/ajr.164.5.7717243","article-title":"Retrieval of intravascular foreign bodies: experience in 32 cases","volume":"164","author":"Egglin","year":"1995","journal-title":"AJR Am J Roentgenol"}],"container-title":["European Heart Journal -
