One type of malignant conformation is an anomalous left anterior descending artery (LAD) arising from the right coronary artery (RCA). In a study examining 70\u2005850 patients undergoing coronary angiography, the prevalence of this anomaly was noted in 0.006% of total patients and in 2.3% of congenital coronary anomaly cases. Of the four patients presenting with this anomaly, only one was noted to have an interarterial course of the LAD between the aorta and pulmonary artery. We describe the case of a patient who was incidentally found to have a malignant anomalous LAD arising from the RCA when he presented with a non-ST elevation myocardial infarction due to a ruptured plaque in an obtuse marginal branch. This patient survived for 57\u2005years with no symptoms.<\/jats:p>","DOI":"10.1136\/bcr-2013-200598","type":"journal-article","created":{"date-parts":[[2013,8,5]],"date-time":"2013-08-05T09:58:05Z","timestamp":1375696685000},"page":"bcr2013200598","source":"Crossref","is-referenced-by-count":5,"title":["Asymptomatic anomalous left anterior descending artery arising from the right coronary artery with a rare anterior course"],"prefix":"10.1136","volume":"2013","author":[{"given":"Francisco O","family":"Nascimento","sequence":"first","affiliation":[{"name":"Department of Cardiology, Mount Sinai Medical Center, Miami Beach, Florida, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milla J","family":"Kviatkovsky","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Mount Sinai Medical Center, Miami Beach, Florida, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maiteder","family":"Larrauri-Reyes","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Mount Sinai Medical Center, Miami Beach, Florida, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nirat","family":"Beohar","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Mount Sinai Medical Center, Miami Beach, Florida, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2013,8,5]]},"reference":[{"key":"2025082802103140000_2013.aug05_1.bcr2013200598.1","first-page":"E240","article-title":"Anomalous origin of all three coronary arteries from right sinus of Valsalva in a patient with angina pectoris","volume":"2013","author":"Modi","year":"2011","journal-title":"J Invasive Cardiol"},{"key":"2025082802103140000_2013.aug05_1.bcr2013200598.2","first-page":"574","article-title":"Origin and distribution anomalies of the left anterior descending artery in 70,850 adult patients: multicenter data collection","volume":"2013","author":"Tuncer","year":"2006","journal-title":"Catheter Cardiovasc Interv"},{"key":"2025082802103140000_2013.aug05_1.bcr2013200598.3","doi-asserted-by":"crossref","first-page":"428","DOI":"10.1016\/S0002-8703(97)70184-4","article-title":"Anomalous right or left coronary artery from the contralateral coronary sinus: \u201chigh-risk\u201d abnormalities in the initial coronary artery course and heterogeneous clinical outcomes","volume":"2013","author":"Taylor","year":"1997","journal-title":"Am Heart J"},{"key":"2025082802103140000_2013.aug05_1.bcr2013200598.4","doi-asserted-by":"crossref","first-page":"122","DOI":"10.1161\/01.CIR.53.1.122","article-title":"Clinical, angiographic, and hemodynamic findings in patients with anomalous origin of the coronary arteries","volume":"2013","author":"Chaitman","year":"1976","journal-title":"Circulation"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2013-200598","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T09:10:38Z","timestamp":1756372238000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2013-200598"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,8,5]]},"references-count":4,"alternative-id":["10.1136\/bcr-2013-200598"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2013-200598","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,8,5]]}}}
