Because follow-up computed tomography after aortic root replacement showed a progressively enlarging left coronary button aneurysm, the patient was judged an acceptable candidate for surgical treatment, considering the potential risk of aneurysmal rupture and subsequent myocardial infarction. The postoperative recovery was uneventful. The patient is doing well 1\u00a0year after the surgery.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>We believe that serial follow-up using computed tomography is mandatory for coronary button aneurysms, and surgical intervention may be considered if progressive enlargement of the aneurysm is observed, especially in younger patients.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13019-021-01645-1","type":"journal-article","created":{"date-parts":[[2021,9,6]],"date-time":"2021-09-06T13:02:59Z","timestamp":1630933379000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Left coronary button aneurysm presenting with progressive enlargement after aortic root replacement"],"prefix":"10.1186","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0306-3758","authenticated-orcid":false,"given":"Kimihiro","family":"Kobayashi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshinori","family":"Kuroda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Mizumoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsushi","family":"Yamashita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiichi","family":"Ohba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shingo","family":"Nakai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomonori","family":"Ochiai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuro","family":"Uchida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,9,6]]},"reference":[{"key":"1645_CR1","doi-asserted-by":"publisher","first-page":"691","DOI":"10.1016\/S0022-5223(19)35873-8","volume":"92","author":"NT Kouchoukos","year":"1986","unstructured":"Kouchoukos NT, Marshall WG Jr, Wedige-Stecher TA.
