Pregnancy in women with ATS is extremely uncommon, and optimal perinatal management strategies are not well defined. We describe a 38\u2010year\u2010old primigravida with genetically confirmed ATS (p.R228X) who presented at 31\u2009weeks of gestation without medication. During pregnancy, the burden of premature ventricular contractions and non\u2010sustained ventricular tachycardia decreased compared with the pre\u2010pregnancy period. At 36\u2009weeks, atenolol and flecainide were introduced, and a wearable cardioverter\u2010defibrillator (WCD) was applied, further reducing arrhythmias. A planned cesarean section at 37\u2009weeks was uneventful, with favorable maternal and fetal outcomes. Postpartum, arrhythmias increased again, highlighting the importance of surveillance. This case demonstrates that combined pharmacological therapy and temporary WCD use may represent a safe and effective perinatal management strategy in high\u2010risk pregnancies complicated by ATS.\n                  <\/jats:p>","DOI":"10.1111\/jog.70181","type":"journal-article","created":{"date-parts":[[2026,1,3]],"date-time":"2026-01-03T03:50:16Z","timestamp":1767412216000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Perinatal Management of Andersen\u2013Tawil Syndrome Using a Wearable Cardioverter\u2010Defibrillator: A Case Report"],"prefix":"10.1111","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-1314-4621","authenticated-orcid":false,"given":"Yuta","family":"Sakaguchi","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine Niigata University Graduate School of Medical and Dental Sciences  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sou","family":"Otsuki","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine Niigata University Graduate School of Medical and Dental Sciences  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daisuke","family":"Izumi","sequence":"additional","affiliation":[{"name":"Department of Cardiology Niigata Shibata Hospital  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaomi","family":"Chinushi","sequence":"additional","affiliation":[{"name":"Graduate School of Health Sciences Niigata University School of Medicine  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takayuki","family":"Inomata","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine Niigata University Graduate School of Medical and Dental Sciences  Niigata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,2]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(01)00342-7"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1172\/JCI15183"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.31092"},{"key":"e_1_2_12_5_1","first-page":"987","article-title":"Andersen\u2013Tawil Syndrome With KCNJ2 Mutation in Pregnancy: A Case Report","volume":"51","author":"Itoh H.","year":"2008","journal-title":"Journal of Cardiology"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joa.2012.08.002"},{"key":"e_1_2_12_7_1","article-title":"Perinatal Management of Andersen\u2013Tawil Syndrome: A Case Report","volume":"26","author":"Saito D.","year":"2021","journal-title":"Annals of Noninvasive Electrocardiology"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/jog.14553"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1186\/1750-1172-3-18"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.109.863209"},{"key":"e_1_2_12_11_1","first-page":"e41","article-title":"Beta\u2010Blocker Therapy for Long QT Syndrome and Catechoraminergic Polymorphic Ventricular Tachycardia: Are All Veta\u2010Blockers Equivalent?","volume":"14","author":"Ackerman M.
