The fetus with confirmed normal karyotype had HF in the presence of atrial flutter and sustained ventricular rate of 200\u2013210\u2005bpm at gestational week (GW) 31<jats:sup>\u20136\/7<\/jats:sup>. Aetiologies of HF other than fetal tachyarrhythmia were unlikely in this infant. The patient's family declined pharmacological treatment with maternal digoxin and desired to continue pregnancy with only intensive monitoring of fetal condition. Maternal transplacental \u03b2-methasone was given to facilitate fetal lung maturation. The fetal tachyarrhythmia ameliorated to 190\u2005bpm at GW 32<jats:sup>\u20135\/7<\/jats:sup>and HF gradually disappeared by birth. The otherwise healthy female neonate weighing 3050\u2005g born at GW 37<jats:sup>\u20130\/7<\/jats:sup>was successfully treated with cardioversion performed 60\u2005min after birth. This case suggested that corticosteroid therapy contributed to the resolution of HF associated with tachyarrhythmia.<\/jats:p>","DOI":"10.1136\/bcr-2015-211948","type":"journal-article","created":{"date-parts":[[2015,12,1]],"date-time":"2015-12-01T00:37:39Z","timestamp":1448930259000},"page":"bcr2015211948","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Resolution of tachyarrhythmia-related fetal hydrops after corticosteroid administration for fetal lung maturation"],"prefix":"10.1136","volume":"2015","author":[{"given":"Kohta","family":"Takei","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mamoru","family":"Morikawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazutoshi","family":"Cho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hisanori","family":"Minakami","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,11,3]]},"reference":[{"doi-asserted-by":"publisher","key":"2025042707323480000_2015.nov03_1.bcr2015211948.1","DOI":"10.1161\/01.cir.0000437597.44550.5d"},{"doi-asserted-by":"publisher","key":"2025042707323480000_2015.nov03_1.bcr2015211948.2","DOI":"10.1016\/j.ajog.2014.12.018"},{"doi-asserted-by":"publisher","key":"2025042707323480000_2015.nov03_1.bcr2015211948.3","DOI":"10.1002\/ajmg.a.36988"},{"doi-asserted-by":"publisher","key":"2025042707323480000_2015.nov03_1.bcr2015211948.4","DOI":"10.1080\/14767050600682446"},{"doi-asserted-by":"publisher","key":"2025042707323480000_2015.nov03_1.bcr2015211948.5","DOI":"10.1542\/peds.2006-3680"},{"doi-asserted-by":"publisher","key":"2025042707323480000_2015.nov03_1.bcr2015211948.6","DOI":"10.1016\/0735-1097(96)00054-X"},{"key":"2025042707323480000_2015.nov03_1.bcr2015211948.7","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1016\/S0002-9378(16)34143-6","article-title":"Perinatal outcome of paroxysmal tachycardia of the newborn with onset in utero.
