Although conventional catheter angiography (CCA) remains the reference standard for hemodynamic evaluation, cardiac computed tomography angiography (CTA) has emerged as an increasingly valuable tool for anatomical assessment in the preoperative evaluation of Fontan candidates. Objective: To compare the anatomical and hemodynamic information provided by CTA and CCA before Fontan completion and to evaluate their complementary roles in the preoperative assessment of pediatric patients with single-ventricle physiology. Methods: This single-center, retrospective study included 32 patients with single-ventricular physiology who underwent staged palliation and Fontan completion. All patients underwent TTE and CCA. Twenty-three patients also underwent cardiac CTA with three-dimensional reconstruction. Anatomical and hemodynamic findings obtained from CTA and CCA were compared, with particular focus on extracardiac anatomy, collateral vessels, and findings relevant to surgical planning. Results: Cardiac CTA showed concordant detection of clinically significant anatomical findings identified by CCA, while providing a more comprehensive assessment of extracardiac anatomy. While CCA remained superior for hemodynamic assessment, CTA provided more comprehensive evaluation of extracardiac anatomy. In this cohort, catheterization findings did not alter the planned surgical strategy (0%, 95% CI 0\u201310.9%). Conclusions: CTA may provide valuable anatomical information for preoperative assessment and surgical planning; however, larger prospective multicenter studies are required before less invasive pre-Fontan evaluation strategies can be considered.<\/jats:p>","DOI":"10.3390\/jcm15135286","type":"journal-article","created":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T08:04:49Z","timestamp":1783411489000},"page":"5286","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Complementary Roles of Cardiac Computed Tomography Angiography and Catheter Angiography Before Fontan Completion in Patients with Single-Ventricle Physiology: A Single-Center Experience"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4919-083X","authenticated-orcid":false,"given":"Burcu","family":"\u00c7evlik","sequence":"first","affiliation":[{"name":"Department of Pediatric Cardiology, Saglik Bilimleri UniversitBasaksehir Cam and Sakura City Hospital, Istanbul 34480, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmet Saki","family":"O\u011fuz","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Saglik Bilimleri UniversitBasaksehir Cam and Sakura City Hospital, Istanbul 34480, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-5360-7044","authenticated-orcid":false,"given":"Demet","family":"Kangel","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Saglik Bilimleri UniversitBasaksehir Cam and Sakura City Hospital, Istanbul 34480, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kahraman","family":"Yakut","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Saglik Bilimleri UniversitBasaksehir Cam and Sakura City Hospital, Istanbul 34480, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4579-963X","authenticated-orcid":false,"given":"Muhammet Hamza Halil","family":"Toprak","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Saglik Bilimleri UniversitBasaksehir Cam and Sakura City Hospital, Istanbul 34480, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0130brahim Cansaran","family":"Tan\u0131d\u0131r","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Saglik Bilimleri UniversitBasaksehir Cam and Sakura City Hospital, Istanbul 34480, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3607-0620","authenticated-orcid":false,"given":"Serap","family":"Ba\u015f","sequence":"additional","affiliation":[{"name":"Department of Radiology, Saglik Bilimleri University Basaksehir Cam and Sakura City Hospital, Istanbul 34480, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali Can","family":"Hatemi","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiovascular Surgery, Saglik Bilimleri University Basaksehir Cam and Sakura Hospital, Istanbul 34480, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1762-3269","authenticated-orcid":false,"given":"Erkut","family":"\u00d6zt\u00fcrk","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Saglik Bilimleri UniversitBasaksehir Cam and Sakura City Hospital, Istanbul 34480, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"839","DOI":"10.1136\/hrt.2004.051789","article-title":"Fontan circulation","volume":"91","author":"Gewillig","year":"2005","journal-title":"Heart"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"240","DOI":"10.1136\/thx.26.3.240","article-title":"Surgical repair of tricuspid atresia","volume":"26","author":"Fontan","year":"1971","journal-title":"Thorax"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"184","DOI":"10.1016\/j.jacc.2004.02.058","article-title":"Diagnostic assessment before Fontan operation in patients with bidirectional cavopulmonary anastomosis: Are noninvasive methods sufficient?","volume":"44","author":"Ro","year":"2004","journal-title":"J.
