Furthermore, aortopulmonary fistula is a rare congenital heart disease of adult onset. We report the case of a 79-year-old man who presented with chest pain. ECG-gated cardiac CT and coronary artery angiography revealed an anomalous vessel arising from the right coronary cusp and a CAF from the left coronary descending artery. These fistulas coalesced and drained into the same portion of the pulmonary artery. Haemodynamic studies revealed that the estimated systemic-to-pulmonary flow ratio was 1.18. The mean pulmonary pressure was 14\u2009mm Hg. We decided against surgical intervention due to his advanced age and lack of heart failure symptoms. The patient did not have any worsening heart failure and chest pain on follow-up. This was a rare case of CAF coexistent and coalesced with an aortopulmonary fistula.<\/jats:p>","DOI":"10.1136\/bcr-2021-244035","type":"journal-article","created":{"date-parts":[[2021,7,23]],"date-time":"2021-07-23T13:33:47Z","timestamp":1627047227000},"page":"e244035","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Rare case of congenital coronary artery fistula coexistent and coalesced with aortopulmonary fistula"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1602-7529","authenticated-orcid":false,"given":"Takumi","family":"Osawa","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine, Mito Medical Center, Mito, Ibaraki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuta","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Mito Medical Center, Mito, Ibaraki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomomi","family":"Koizumi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Mito Medical Center, Mito, Ibaraki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,7,23]]},"reference":[{"key":"2025082803424363000_14.7.e244035.1","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.13.11613"},{"key":"2025082803424363000_14.7.e244035.2","doi-asserted-by":"crossref","first-page":"380","DOI":"10.1097\/RTI.0000000000000232","article-title":"Coronary-Pulmonary artery fistulas: a systematic review","volume":"31","author":"Verdini","year":"2016","journal-title":"J Thorac Imaging"},{"key":"2025082803424363000_14.7.e244035.3","doi-asserted-by":"crossref","first-page":"273","DOI":"10.1007\/s10554-010-9711-3","article-title":"Coronary to pulmonary artery fistula: morphologic features at multidetector CT","volume":"26","author":"Kim","year":"2010","journal-title":"Int J Cardiovasc Imaging"},{"key":"2025082803424363000_14.7.e244035.4","doi-asserted-by":"crossref","DOI":"10.1259\/bjr.20140754","article-title":"Coronary artery fistula in adults: evaluation with dual-source CT coronary angiography","volume":"88","author":"Zhou","year":"2015","journal-title":"Br J Radiol"},{"key":"2025082803424363000_14.7.e244035.5","doi-asserted-by":"crossref","first-page":"317","DOI":"10.1016\/j.hrtlng.2019.11.002","article-title":"Aorto-cardiac fistula etiology, presentation, and management: a systematic review","volume":"49","author":"Foster","year":"2020","journal-title":"Heart Lung"},{"key":"2025082803424363000_14.7.e244035.6","doi-asserted-by":"crossref","first-page":"688","DOI":"10.1148\/rg.2018170158","article-title":"Coronary artery fistulas: pathophysiology, imaging findings, and management","volume":"38","author":"Yun","year":"2018","journal-title":"Radiographics"},{"key":"2025082803424363000_14.7.e244035.7","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.108.190811"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2021-244035","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T10:42:51Z","timestamp":1756377771000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2021-244035"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,7]]},"references-count":7,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2021,7,23]]},"published-print":{"date-parts":[[2021,7]]}},"alternative-id":["10.1136\/bcr-2021-244035"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2021-244035","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,7]]}}}
