Since many of these diseases are inherited as autosomal dominant, offspring have about a 50% risk of having the disease, though many will be only mildly impacted during fetal life. However, highly complex delivery room preparation is increasingly needed in pregnancies with inherited arrhythmia syndromes (IASs). However, specific Doppler techniques show meanwhile a better understanding of fetal electrophysiology. The advent of fetal magnetocardiography (FMCG) now allows the detection of fetal Torsades de Pointes (TdP) ventricular tachycardia and other LQT-associated arrhythmias (QTc prolongation, functional second AV block, T-wave alternans, sinus bradycardia, late-coupled ventricular ectopy and monomorphic VT) in susceptible fetuses during the second and third trimester. These types of arrhythmias can be due to either de novo or familial Long QT Syndrome (LQTS), Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), or other IAS. It is imperative that the multiple specialists involved in the antenatal, peripartum, and neonatal care of these women and their fetuses\/infants have the optimal knowledge, training and equipment in order to care for these highly specialized pregnancies and deliveries. In this review, we outline the steps to recognize symptomatic LQTS in either the mother, fetus or both, along with suggestions for evaluation and management of the pregnancy, delivery, or post-partum period impacted by LQTS.<\/jats:p>","DOI":"10.3390\/jcm12103379","type":"journal-article","created":{"date-parts":[[2023,5,10]],"date-time":"2023-05-10T01:57:51Z","timestamp":1683683871000},"page":"3379","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Preventing and Treating Torsades de Pointes in the Mother, Fetus and Newborn in the Highest Risk Pregnancies with Inherited Arrhythmia Syndromes"],"prefix":"10.3390","volume":"12","author":[{"given":"Annette","family":"Wacker-Gussmann","sequence":"first","affiliation":[{"name":"Department of Pediatric Cardiology and Congenital Heart Disease, German Heart Center Munich, 80636 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gretchen K.","family":"Eckstein","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Departments of Pediatrics and Biomedical Engineering, Children\u2019s Wisconsin, Herma Heart Institute, Medical College of Wisconsin, Milwaukee, WI 53226, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janette F.","family":"Strasburger","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Departments of Pediatrics and Biomedical Engineering, Children\u2019s Wisconsin, Herma Heart Institute, Medical College of Wisconsin, Milwaukee, WI 53226, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"674","DOI":"10.1016\/j.hrcr.2022.07.007","article-title":"Presentation and genetic confirmation of long QT syndrome in the fetus","volume":"8","author":"Zidere","year":"2022","journal-title":"HeartRhythm Case Rep."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1073","DOI":"10.1016\/S1701-2163(16)35437-8","article-title":"Long QT syndrome in pregnancy: Are vaginal delivery and use of oxytocin permitted? a case report","volume":"34","author":"Martillotti","year":"2012","journal-title":"J.
