The presence of multiple coronary artery aneurysms located in more than one coronary artery is even more uncommon. The pathophysiology of such aneurysms is unknown, but the majority are often due to atherosclerosis, congenital heart disease, or vasculitis.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>We present a rare case of a 78-year-old female patient who presented with unstable angina and non-ST segment elevation myocardial infarction. On coronary angiography, she was found to have three separate 1\u2009cm saccular aneurysms involving the proximal left anterior descending coronary artery. The right coronary artery could not be visualized. Computed chest tomography revealed a 6.6\u2009\u00d7\u20096.3\u2009cm saccular aneurysm of the right coronary artery, and a 4.4\u2009cm fusiform aneurysm of the ascending aorta. The patient gave no history of percutaneous coronary intervention or cardiac surgical procedures. She had a previous history of endovascular stenting of an abdominal aortic aneurysm. The sizable right coronary artery aneurysm showed extrinsic compression of both the right atrium and ventricle with right ventricular hypokinesis. Serological studies for vasculitis were all negative. Pathology of the aneurysm wall revealed calcific atherosclerosis without evidence of vasculitis. The patient underwent subtotal resection of the right coronary aneurysm with ligation of the proximal and distal ends of the right coronary artery and double bypass surgery to the left anterior descending and right posterior descending coronary arteries.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The presence of multiple, large coronary artery aneurysms is very rare. Treatment can be challenging and should be individualized. Surgical treatment is recommended for giant coronary artery aneurysms to prevent potential complications.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13019-021-01560-5","type":"journal-article","created":{"date-parts":[[2021,6,19]],"date-time":"2021-06-19T12:02:29Z","timestamp":1624104149000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Giant coronary artery aneurysms involving more than one coronary artery: case report"],"prefix":"10.1186","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7077-8107","authenticated-orcid":false,"given":"Matthew S","family":"Khouzam","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nayer","family":"Khouzam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,6,19]]},"reference":[{"issue":"1","key":"1560_CR1","doi-asserted-by":"publisher","first-page":"134","DOI":"10.1161\/01.cir.67.1.134","volume":"67","author":"PS Swaye","year":"1983","unstructured":"Swaye PS, Fisher LD, Litwin P, Vignola PA, Judkins MP, Kemp HG, et al.
