SAS ranges from localized obstructive membranes to complex tunnel narrowing and often coexists with other CHD like ventricular septal defect, interrupted aortic arch, and aortic coarctation. Despite generally successful surgeries, SAS recurs in 5%\u201330% of patients, necessitating reoperation. Recurrence factors include younger age at initial surgery, higher preoperative LVOT gradients, and complex anatomical presentations. This report discusses an 11-year-old girl with recurrent SAS who underwent a modified Konno operation. It emphasizes the need for meticulous surgical technique and vigilant postoperative follow-up to manage SAS and reduce recurrence risk effectively. The case highlights the challenges of this CHD and underscores the importance of personalized, comprehensive care strategies.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf100","type":"journal-article","created":{"date-parts":[[2025,3,4]],"date-time":"2025-03-04T22:20:02Z","timestamp":1741126802000},"source":"Crossref","is-referenced-by-count":0,"title":["Surgical management of recurrent subaortic stenosis: a case report of the modified Konno operation"],"prefix":"10.1093","volume":"2025","author":[{"given":"Alwaleed","family":"Al-Dairy","sequence":"first","affiliation":[{"name":"Assistant Professor in Cardiac Surgery at the Faculty of Medicine , Damascus University, Damascus ,","place":["Syria"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3173-1942","authenticated-orcid":false,"given":"Ahmad","family":"Al-Bitar","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Damascus University , Damascus ,","place":["Syria"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,2,28]]},"reference":[{"key":"2025030422194559700_ref1","doi-asserted-by":"publisher","first-page":"614","DOI":"10.1007\/s00246-020-02522-9","article-title":"Management of complex left ventricular outflow tract obstruction: a comparison of Konno and modified Konno techniques","volume":"42","author":"Haider","year":"2021","journal-title":"Pediatr Cardiol"},{"key":"2025030422194559700_ref2","doi-asserted-by":"publisher","first-page":"885","DOI":"10.1016\/j.ejcts.2008.01.049","article-title":"Risk factors for reoperation after relief of congenital subaortic stenosis","volume":"33","author":"Dodge-Khatami","year":"2008","journal-title":"Eur J Cardio-Thoracic Surg"},{"key":"2025030422194559700_ref3","doi-asserted-by":"publisher","first-page":"549","DOI":"10.1093\/ejcts\/ezz046","article-title":"Echocardiographic predictors of reoperation for subaortic stenosis in children and adults","volume":"56","author":"Theocharis","year":"2019","journal-title":"Eur J Cardio-Thoracic Surg"},{"key":"2025030422194559700_ref4","doi-asserted-by":"publisher","DOI":"10.3389\/fcvm.2018.00122","article-title":"Discrete subaortic stenosis: perspective roadmap to a complex disease","volume":"5","author":"Mass\u00e9","year":"2018","journal-title":"Front Cardiovasc Med"},{"key":"2025030422194559700_ref5","doi-asserted-by":"publisher","first-page":"588","DOI":"10.1093\/icvts\/ivab121","article-title":"Paediatric subaortic stenosis: long-term outcome and risk factors for reoperation","volume":"33","author":"De Wolf","year":"2021","journal-title":"Interact Cardiovasc Thorac Surg"},{"key":"2025030422194559700_ref6","doi-asserted-by":"publisher","first-page":"179","DOI":"10.1016\/j.hlc.2016.05.120","article-title":"Outcomes of subaortic obstruction resection in children","volume":"26","author":"Donald","year":"2017","journal-title":"Hear Lung Circ"},{"key":"2025030422194559700_ref7","doi-asserted-by":"publisher","first-page":"1106","DOI":"10.1007\/s00246-017-1622-9","article-title":"When is it better to wait?
