They are benign in the vast majority of cases, whereas a small minority may be affected by serious consequences such as myocardial infarction, arrhythmia, cardiac arrest, and even death. We herein describe a 62-year-old man with sudden and severe substernal chest pain; Q waves in electrocardiographic leads II, III, and aVF; and positive serum troponin I enzyme. Left heart cardiac catheterization revealed triple coronary vessel disease with a 60% to 70% occlusion in the left main coronary artery (LMCA). The left anterior descending (LAD) and the left circumflex artery arose from the ostium of the right coronary artery. Additionally, a rudimentary type IV dual LAD originated from the LMCA. A coronary artery bypass graft surgery was performed using a left internal mammary artery graft for the LAD and a saphenous vein graft for the diagonal branches (I &amp; II) of the LAD and the posterior descending artery. The patient was discharged after an uneventful 1-week hospital course.<\/jats:p>","DOI":"10.18502\/jthc.v17i2.9842","type":"journal-article","created":{"date-parts":[[2022,6,25]],"date-time":"2022-06-25T07:39:47Z","timestamp":1656142787000},"source":"Crossref","is-referenced-by-count":0,"title":["A Rare Case of a Type IV Dual Left Anterior Descending Artery and Ectopic Left Anterior Descending and Circumflex Arteries Requiring Surgery"],"prefix":"10.18502","author":[{"given":"Muhammad","family":"Mansoor","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Waqar Ahmad","family":"Khan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fakhar","family":"Abbas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Usha","family":"Kumari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7770","published-online":{"date-parts":[[2022,6,22]]},"container-title":["The Journal of Tehran University Heart Center"],"original-title":[],"link":[{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JTHC\/article\/download\/9842\/9359","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JTHC\/article\/download\/9842\/9359","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,12,17]],"date-time":"2024-12-17T17:02:50Z","timestamp":1734454970000},"score":1,"resource":{"primary":{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JTHC\/article\/view\/9842"},"secondary":[{"URL":"https:\/\/jthc.tums.ac.ir\/index.php\/jthc\/article\/view\/1598","label":"UNIVERSITY"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JTHC\/article\/view\/9842","label":"PUBLISHER"}]},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6,22]]},"references-count":0,"URL":"https:\/\/doi.org\/10.18502\/jthc.v17i2.9842","relation":{},"ISSN":["2008-2371","1735-8620"],"issn-type":[{"type":"electronic","value":"2008-2371"},{"type":"print","value":"1735-8620"}],"subject":[],"published":{"date-parts":[[2022,6,22]]}}}
