In this part, we focus on prenatal prediction of postnatal BAS. Materials and Methods: This retrospective study was conducted at the Department of Prenatal Cardiology, Polish Mother\u2019s Memorial Hospital in Lodz, covering the years 2014\u20132024. From a total of 112 prenatally diagnosed d-TGA cases, 70 fetuses (46 with isolated d-TGA and 24 with d-TGA and VSD) met the inclusion criteria; follow-up of four pregnancies ended up in other hospitals, so the final series was 66 cases. Statistical analyses were performed using Statistica software. Results: Out of 66 analyzed cases, 32 newborns (48%) required postnatal BAS, with 87.5% of these procedures performed within the first 24\u201348 hours of life. Prenatal echocardiography correctly predicted the postnatal management pathway in 90.9% of cases (60\/66), identifying all 26 neonates requiring urgent balloon atrial septostomy (100% positive predictive value), while 6 neonates in the planned group required unexpected postnatal septostomy. We noted that the 18% (n=6) of cases not identified prenatally occurred when the last scan was performed &gt; 14 days before birth, suggesting that the time interval significantly impacts the reliability of late-gestation FO assessment. The study identified 10 prenatal \u201cred flags,\u201d including FO size &lt; 3 mm, bi-directional FO flow, and pulmonary vein velocity \u2265 45 cm\/s and other features, as high-reliability indicators for urgent postnatal intervention. Conclusion: Prenatal functional assessment of the foramen ovale in the late third trimester was highly effective in predicting the need for postnatal urgent BAS in d-TGA cases. The accuracy of these \u201cred flags\u201d was significantly higher when the last fetal echocardiogram was performed within 14 days to delivery.<\/jats:p>","DOI":"10.1159\/fdt\/acuag022","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T11:50:53Z","timestamp":1792151453000},"source":"Crossref","is-referenced-by-count":0,"title":["Prenatal echocardiographic predictors that increase the risk of urgent Ballon Atrial Septostomy (BAS) after birth in patients with Dextro-Transposition of the Great Arteries- Retrospective Study from Tertiary Center Lodz- Poland ICZMP (2014-2024)"],"prefix":"10.1159","author":[{"given":"Aleksandra","family":"Moszura","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iwona","family":"Strzelecka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Respondek-Liberska","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,10,16]]},"container-title":["Fetal Diagnosis and Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/fdt\/acuag022","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T16:01:11Z","timestamp":1792166471000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/fdt\/acuag022"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10,16]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/fdt\/acuag022","archive":["Portico"],"relation":{},"ISSN":["1015-3837","1421-9964"],"issn-type":[{"value":"1015-3837","type":"print"},{"value":"1421-9964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10,16]]}}}
