Serial fetal echocardiography may provide dynamic information to support postnatal decision-making. Case Presentation: We report the case of a fetus diagnosed at 32 weeks\u2019 gestation with a borderline left ventricle, ventricular disproportion, hypoplastic left-sided structures, ductal-dependent systemic circulation, and a non-restrictive ostium secundum atrial septal defect. Serial fetal echocardiographic evaluations demonstrated stable left ventricular dimensions, preserved systolic function, impaired diastolic relaxation, and absence of endomyocardial fibroelastosis. Postnatal echocardiography confirmed hypoplastic aortic arch and coarctation. Following multidisciplinary evaluation, a biventricular repair strategy was selected. At 14 days of life, the patient underwent aortic arch reconstruction and partial atrial septal defect closure with preservation of a small therapeutic interatrial communication. Postoperative evolution was favorable, with progressive left ventricular growth and preserved function. At 2-year follow-up, echocardiography showed normalized mitral and aortic valve z-scores, good left ventricular systolic performance, and no evidence of myocardial fibrosis. Conclusions: This case highlights the value of serial fetal echocardiography in guiding individualized management of borderline left ventricle. Careful assessment of ventricular function and atrial septal physiology may support selection of a biventricular strategy in selected patients and contribute to favorable mid-term outcomes.<\/jats:p>","DOI":"10.3390\/pediatric18010018","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T09:48:08Z","timestamp":1770025688000},"page":"18","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Role of Serial Fetal Echocardiography in Postnatal Surgical Decision-Making for Borderline Left Ventricle: A Case Report"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4321-6229","authenticated-orcid":false,"given":"Andreea","family":"Cerghit-Paler","sequence":"first","affiliation":[{"name":"Doctoral School, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu-Mure\u0219, 540139 T\u00e2rgu-Mure\u0219, Romania"},{"name":"Department of Pediatrics III, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu-Mure\u0219, 540139 T\u00e2rgu-Mure\u0219, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dorottya","family":"Gabor-Miklosi","sequence":"additional","affiliation":[{"name":"Doctoral School, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu-Mure\u0219, 540139 T\u00e2rgu-Mure\u0219, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iolanda","family":"Muntean","sequence":"additional","affiliation":[{"name":"Department of Pediatrics III, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu-Mure\u0219, 540139 T\u00e2rgu-Mure\u0219, Romania"},{"name":"Emergency Institute of Cardiovascular Diseases and Transplantation, 540139 T\u00e2rgu-Mure\u0219, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George-Andrei","family":"Crauciuc","sequence":"additional","affiliation":[{"name":"Center for Advanced Medical and Pharmaceutical Research, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu-Mure\u0219, 540139 T\u00e2rgu-Mure\u0219, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Toma","sequence":"additional","affiliation":[{"name":"Department of Pediatrics III, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu-Mure\u0219, 540139 T\u00e2rgu-Mure\u0219, Romania"},{"name":"Emergency Institute of Cardiovascular Diseases and Transplantation, 540139 T\u00e2rgu-Mure\u0219, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Beligan","sequence":"additional","affiliation":[{"name":"Emergency Institute of Cardiovascular Diseases and Transplantation, 540139 T\u00e2rgu-Mure\u0219, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liliana","family":"Gozar","sequence":"additional","affiliation":[{"name":"Department of Pediatrics III, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu-Mure\u0219, 540139 T\u00e2rgu-Mure\u0219, Romania"},{"name":"Emergency Institute of Cardiovascular Diseases and Transplantation, 540139 T\u00e2rgu-Mure\u0219, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1016\/j.ejcts.2004.10.034","article-title":"Borderline Left Ventricle","volume":"27","author":"Corno","year":"2005","journal-title":"Eur.
