A few hours before the scheduled angiography, she presented to the emergency room with chest pain and diffuse ST-segment modifications leading to emergent coronary angiography. Recent PET-CT ischemia and viability maps were available at the time of the intervention, favoring a percutaneous coronary intervention for chronic total occlusion (CTO PCI) of the left circumflex artery, apart from the culprit lesion of the left main coronary artery and left anterior descending artery, with good results. A second PET-CT scan 23 days post-PCI showed a reversible perfusion defect of the first diagonal branch territory, which was subsequently treated. A rapid normalization of the left ventricular ejection fraction (LVEF) was noted after revascularization, while the second PET-CT showed no signs of significant myocardial necrosis. This case illustrates the potential role of cardiac imaging perfusion studies in guiding revascularization in complex cases in the context of an acute myocardial infarction (MI).<\/jats:p>","DOI":"10.3389\/fcvm.2025.1637403","type":"journal-article","created":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T06:30:44Z","timestamp":1761719444000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case Report: PET-CT ischemia and viability maps guiding an emergency revascularization"],"prefix":"10.3389","volume":"12","author":[{"given":"Dionysios","family":"Adamopoulos","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L\u00e9o","family":"Meyer de Stadelhofen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fran\u00e7ois","family":"Mach","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valentina","family":"Garibotto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"St\u00e9phane","family":"Noble","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,10,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2921","DOI":"10.1161\/01.CIR.99.22.2921","article-title":"Prevalence of myocardial viability as detected by positron emission tomography in patients with ischemic cardiomyopathy","volume":"99","author":"Auerbach","year":"1999","journal-title":"Circulation"},{"key":"B2","doi-asserted-by":"publisher","first-page":"409","DOI":"10.1007\/s00059-020-04935-x","article-title":"ESC 2019 guidelines for the diagnosis and management of chronic coronary syndromes: recommendations for cardiovascular imaging","volume":"45","author":"Saraste","year":"2020","journal-title":"Herz"},{"key":"B3","doi-asserted-by":"publisher","first-page":"1151","DOI":"10.1016\/S0735-1097(02)01726-6","article-title":"Myocardial viability testing and impact of revascularization on prognosis in patients with coronary artery disease and left ventricular dysfunction: a meta-analysis","volume":"39","author":"Allman","year":"2002","journal-title":"J Am Coll Cardiol"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1154","DOI":"10.1001\/jamacardio.2023.3803","article-title":"Viability and outcomes with revascularization or medical therapy in ischemic ventricular dysfunction: a prespecified secondary analysis of the REVIVED-BCIS2 trial","volume":"8","author":"Perera","year":"2023","journal-title":"JAMA Cardiol"},{"key":"B5","doi-asserted-by":"publisher","first-page":"739","DOI":"10.1056\/NEJMoa1807365","article-title":"Myocardial viability and long-term outcomes in ischemic cardiomyopathy","volume":"381","author":"Panza","year":"2019","journal-title":"N Engl J Med"},{"key":"B6","doi-asserted-by":"publisher","first-page":"e000053","DOI":"10.1161\/HCI.0000000000000053","article-title":"State of the art: imaging for myocardial viability: a scientific statement from the American Heart Association","volume":"13","author":"Garcia","year":"2020","journal-title":"Circ Cardiovasc Imaging"},{"key":"B7","doi-asserted-by":"publisher","first-page":"87","DOI":"10.1093\/eurheartj\/ehy394","article-title":"2018 ESC\/EACTS guidelines on myocardial revascularization","volume":"40","author":"Neumann","year":"2019","journal-title":"Eur Heart J"}],"container-title":["Frontiers in Cardiovascular Medicine"],"original-title":[],"link":[{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fcvm.2025.1637403\/full","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T06:30:44Z","timestamp":1761719444000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fcvm.2025.1637403\/full"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,29]]},"references-count":7,"alternative-id":["10.3389\/fcvm.2025.1637403"],"URL":"https:\/\/doi.org\/10.3389\/fcvm.2025.1637403","relation":{},"ISSN":["2297-055X"],"issn-type":[{"value":"2297-055X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,29]]},"article-number":"1637403"}}
