Her immediate postoperative course was uncomplicated, and she was discharged home after a 7-day hospital stay. Electrocardiogram-gated coronary computed tomography angiography incidentally revealed an anomalous left anterior descending coronary artery (LAD) originating from the right coronary sinus without an intramural course, situated below the mechanical pulmonary valve. Positron emission tomography myocardial perfusion imaging demonstrated a large area of stress-induced ischemia in the LAD territory, along with a small area of transmural infarction in the distal LAD region. Subsequent cardiovascular magnetic resonance imaging (CMRI) confirmed extensive transmural late gadolinium enhancement in the LAD territory and right ventricular outflow tract. Adenosine stress perfusion CMRI showed no new inducible ischemia. This case underscores the importance of preoperative coronary imaging in patients with TOF undergoing reintervention to prevent inadvertent coronary injury and highlights the role of advanced imaging modalities in diagnosing and managing complex congenital heart disease.<\/jats:p>","DOI":"10.4103\/apc.apc_47_25","type":"journal-article","created":{"date-parts":[[2025,10,7]],"date-time":"2025-10-07T17:04:07Z","timestamp":1759856647000},"page":"301-304","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Undetected coronary anomaly in tetralogy of Fallot: A preventable cause of persistent angina post redo surgery"],"prefix":"10.4103","volume":"18","author":[{"given":"Zhen Shan","family":"Hwang","sequence":"first","affiliation":[{"name":"Department of Radiology, National Heart Institute, Kuala Lumpur, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming Chern","family":"Leong","sequence":"additional","affiliation":[{"name":"Paediatric and Congenital Heart Centre, National Heart Institute, Kuala Lumpur, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,10,7]]},"reference":[{"key":"R1-20260420","first-page":"54","article-title":"Management of congenital heart disease: State of the art-part ii-cyanotic heart defects","volume":"6","author":"Rao","year":"2019","journal-title":"Children (Basel)"},{"key":"R2-20260420","doi-asserted-by":"crossref","first-page":"537","DOI":"10.1007\/s00246-004-0640-6","article-title":"Repair of tetralogy of Fallot with anomalous coronary arteries coursing across the obstructed right ventricular outflow tract","volume":"26","author":"Ruzmetov","year":"2005","journal-title":"Pediatr Cardiol"},{"key":"R3-20260420","doi-asserted-by":"crossref","first-page":"78","DOI":"10.1016\/j.ijcard.2020.02.037","article-title":"Coronary anomalies in tetralogy of Fallot \u2013 A meta-analysis","volume":"306","author":"Koppel","year":"2020","journal-title":"Int J Cardiol"},{"key":"R4-20260420","doi-asserted-by":"crossref","first-page":"1592","DOI":"10.1016\/j.jacc.2017.01.031","article-title":"Anomalous aortic origin of a coronary artery from the inappropriate sinus of Valsalva","volume":"69","author":"Cheezum","year":"2017","journal-title":"J Am Coll Cardiol"},{"key":"R5-20260420","doi-asserted-by":"crossref","first-page":"983","DOI":"10.1161\/CIRCULATIONAHA.121.055347","article-title":"Coronary artery anomalies","volume":"144","author":"Gentile","year":"2021","journal-title":"Circulation"}],"container-title":["Annals of Pediatric Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/apc.apc_47_25","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T18:58:22Z","timestamp":1786647502000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/apc.apc_47_25"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,5]]},"references-count":5,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.4103\/apc.apc_47_25","relation":{},"ISSN":["0974-2069","0974-5149"],"issn-type":[{"value":"0974-2069","type":"print"},{"value":"0974-5149","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,5]]},"assertion":[{"value":"2025-02-14","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-06-17","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
