This coexistence created competing physiological stress on coronary perfusion as myocardial oxygen delivery to the left ventricle depended on right coronary collateral circulation in the presence of fixed left ventricular outflow obstruction. The child underwent combined surgical repair with reimplantation of the left coronary artery into the aorta and supravalvular aortoplasty. Anaesthesia was induced gradually to avoid abrupt haemodynamic changes, invasive monitoring was established early, and ventilation was adjusted to maintain normocapnia and moderate oxygenation to limit factors that could aggravate coronary steal physiology. The child was separated from bypass on minimal inotropic support and had an uneventful postoperative recovery. This case illustrates the relevance of controlled induction, meticulous haemodynamic balance and coordinated team management for a successful outcome in such a complex case.<\/jats:p>","DOI":"10.1136\/bcr-2025-271192","type":"journal-article","created":{"date-parts":[[2026,7,13]],"date-time":"2026-07-13T11:35:17Z","timestamp":1783942517000},"page":"e271192","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Anaesthetic management of a child with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and supravalvular aortic stenosis (SVAS) associated with Williams-Beuren syndrome undergoing combined coronary reimplantation and supravalvular aortoplasty"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3943-6456","authenticated-orcid":false,"given":"Muhammad Azhar","family":"Sharafat","sequence":"first","affiliation":[{"name":"Anaesthesia, The Aga Khan University Hospital, Karachi, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7565-869X","authenticated-orcid":false,"given":"Muhammad Saad","family":"Yousuf","sequence":"additional","affiliation":[{"name":"Anaesthesia, The Aga Khan University Hospital, Karachi, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad Arslan","family":"Zahid","sequence":"additional","affiliation":[{"name":"Anaesthesia, National Medical Centre, Karachi, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khalid","family":"Samad","sequence":"additional","affiliation":[{"name":"Anaesthesia, The Aga Khan University Hospital, Karachi, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,7,13]]},"reference":[{"key":"2026071304351234000_19.7.e271192.1","doi-asserted-by":"crossref","first-page":"387","DOI":"10.5001\/omj.2016.77","article-title":"Anomalous origin of the left coronary artery from the pulmonary artery: The role of multislice computed tomography (MSCT)","volume":"31","author":"Al Umairi","year":"2016","journal-title":"Oman Med J"},{"key":"2026071304351234000_19.7.e271192.2","doi-asserted-by":"crossref","first-page":"2167","DOI":"10.2147\/JPR.S200534","article-title":"Anesthetic management in untreated Bland-White-Garland syndrome: a case report and literature review","volume":"12","author":"Guo","year":"2019","journal-title":"J Pain Res"},{"key":"2026071304351234000_19.7.e271192.3","doi-asserted-by":"publisher","DOI":"10.1111\/pan.12775"},{"key":"2026071304351234000_19.7.e271192.4","doi-asserted-by":"crossref","first-page":"136","DOI":"10.4103\/0019-5049.151386","article-title":"Anaesthesia for repair of anomalous origin of left coronary artery from pulmonary artery","volume":"59","author":"Gupta","year":"2015","journal-title":"Indian J Anaesth"},{"key":"2026071304351234000_19.7.e271192.5","doi-asserted-by":"crossref","DOI":"10.3390\/jpm13111561","article-title":"Anomalous left coronary artery from the pulmonary artery: how to diagnose and treat","volume":"13","author":"Blickenstaff","year":"2023","journal-title":"J Pers Med"},{"key":"2026071304351234000_19.7.e271192.6","unstructured":"Heward SJ , Shams P , Widrich J .
