A 66-yr old female with a long history of angina and a positive stress test had the anomalous artery coursing anterior to the right ventricular outflow tract. A 42-yr old male with worsening angina after an anteroseptal myocardial infarction had the anomalous artery running between the great vessels. Both patients underwent left internal mammary artery-to-LAD bypass on the beating heart with complete resolution of ischemic symptoms. <\/jats:p><jats:p> Isolated coronary artery anomaly is an uncommon disease (0.6\u20131.2%) in patients undergoing cardiac catheterization [1, 2]. An anomalous origin of the LAD from the proximal right coronary artery (RCA) or the right sinus of Valsalva (RSV) is very rare, found in 1.2\u20136.1% of all coronary anomalies [1, 2]. This coronary anomaly has been considered potentially serious but functionally unimportant [2]. We report two cases of anomalous LAD from the proximal RCA resulting in anterior wall ischemia which was effectively treated by coronary artery bypass surgery. <\/jats:p>","DOI":"10.1177\/096721090301100117","type":"journal-article","created":{"date-parts":[[2022,9,13]],"date-time":"2022-09-13T13:07:43Z","timestamp":1663074463000},"page":"90-92","source":"Crossref","is-referenced-by-count":9,"title":["Two Cases of Anomalous Origin of LAD from Right Coronary Artery Requiring Coronary Artery Bypass"],"prefix":"10.1177","volume":"11","author":[{"given":"Minoru","family":"Ono","sequence":"first","affiliation":[{"name":"Division of Cardiothoracic Surgery, The Ohio State University, N825 Doan Hall, 410 West 10th Avenue, Columbus, OH 43210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Brown","sequence":"additional","affiliation":[{"name":"Division of Cardiothoracic Surgery, The Ohio State University, N825 Doan Hall, 410 West 10th Avenue, Columbus, OH 43210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Randall K.","family":"Wolf","sequence":"additional","affiliation":[{"name":"Division of Cardiothoracic Surgery, The Ohio State University, N825 Doan Hall, 410 West 10th Avenue, Columbus, OH 43210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2003,2,1]]},"reference":[{"key":"bibr1-096721090301100117","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.1810090303"},{"key":"bibr2-096721090301100117","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.1810210110"},{"key":"bibr3-096721090301100117","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(86)80507-1"},{"key":"bibr4-096721090301100117","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.53.1.122"},{"key":"bibr5-096721090301100117","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(92)90019-J"},{"key":"bibr6-096721090301100117","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.72.4.397"}],"container-title":["Cardiovascular Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/096721090301100117","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/096721090301100117","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,1]],"date-time":"2025-03-01T02:38:47Z","timestamp":1740796727000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/096721090301100117"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,2]]},"references-count":6,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2003,2]]}},"alternative-id":["10.1177\/096721090301100117"],"URL":"https:\/\/doi.org\/10.1177\/096721090301100117","relation":{},"ISSN":["0967-2109"],"issn-type":[{"value":"0967-2109","type":"print"}],"subject":[],"published":{"date-parts":[[2003,2]]}}}
