We assessed rates of procedural success with GEC. The primary clinical endpoint was all cause\u2010mortality. Other clinical endpoints included major adverse cardiac events (MACE) during follow\u2010up. Cox regression, multivariate analysis, and propensity score matching were used to compare GEC and non\u2010GEC PCI cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of the 23,299 PCI cases in our study, 532 patients (2%) were treated utilizing GECs. The median age was 66 [IQR 58\u221275], and 88% were males. Successful PCI was performed in 96.2% of the total cohort, with similar rates in the GEC and non\u2010GEC group (94.9% vs. 96.2%,\n                      <jats:italic>p\u2009<\/jats:italic>\n                      =\u20090.144). GEC was used more often in calcified, bifurcation, and unprotected left main lesions. Patients requiring the use of GEC had higher long\u2010term mortality rates (HR 1.86, 95% CI 1.54\u22122.23,\n                      <jats:italic>p\u2009<\/jats:italic>\n                      &lt;\u20090.001) and MACE events (HR 1.26, 95% CI 1.07\u22121.47,\n                      <jats:italic>p\u2009<\/jats:italic>\n                      =\u20090.004). Multivariate adjustments, sensitivity analysis of complex\u2010PCI cases, and a propensity score\u2010matched model showed similar results. A landmark analysis showed no significant difference in 30\u2010day mortality but divergence of the survival curves after 30 days with increased mortality among the GEC cohort.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our study showed that patients who required GEC during PCI were successfully treated in the vast majority of cases, with similar short\u2010term results. However, the use of GEC is associated with a worse long\u2010term prognosis, reflecting a surrogate for sicker patients and procedural complexity, thus requiring careful follow\u2010up.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ccd.70477","type":"journal-article","created":{"date-parts":[[2026,2,9]],"date-time":"2026-02-09T05:56:48Z","timestamp":1770616608000},"page":"1441-1449","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Procedural and Prognostic Implications of Guide Extension Catheter Use During Percutaneous Coronary Intervention: A Retrospective Cohort Study"],"prefix":"10.1002","volume":"107","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0142-0253","authenticated-orcid":false,"given":"Edward","family":"Itelman","sequence":"first","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aviad","family":"Rotholz","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamir","family":"Bental","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2491-9930","authenticated-orcid":false,"given":"Tsahi T.","family":"Lerman","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yeela","family":"Talmor\u2010Barkan","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6935-9765","authenticated-orcid":false,"given":"Hana","family":"Vaknin\u2010Assa","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8699-2447","authenticated-orcid":false,"given":"Amos","family":"Levi","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pablo","family":"Codner","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guy","family":"Witberg","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7708-8253","authenticated-orcid":false,"given":"Ran","family":"Kornowski","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0625-7937","authenticated-orcid":false,"given":"Leor","family":"Perl","sequence":"additional","affiliation":[{"name":"Department of Cardiology Rabin Medical Center Petach\u2010Tikva Israel"},{"name":"Faculty of Medicine Tel Aviv University Tel Aviv Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,2,8]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/EURHEARTJ\/EHY394"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.5603\/CJ.2016.0105"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.25480"},{"issue":"11","key":"e_1_2_10_5_1","first-page":"620","article-title":"A Novel Application of GuideLiner Catheter for Thrombectomy in Acute Myocardial Infarction: A Case Series","volume":"25","author":"Stys A.
