Women with the isolated percutaneous cardiac surgical repair were excluded. Maternal and neonatal outcomes were compared between patients with preexisting cardiac arrhythmias and patients without preexisting cardiac arrhythmias. Maternal outcomes studied were intensive care unit admission, postpartum blood loss greater than 1,000\u2009mL, congestive heart failure development, preeclampsia with severe features, postpartum readmission, postpartum cardiac events, and postpartum length of stay &gt;5 days. Neonatal outcomes investigated were low birth weight &lt;2,500 g, Apgar's scores &lt;7 at 5\u2009minutes, and neonatal intensive care unit admission. Multivariate logistic regression model was used to calculate the adjusted odds ratio (aOR) and 95% confidence intervals.<\/jats:p><jats:p>\n            Results\u2003The outcomes for 69 deliveries from 56 women with a history of open cardiac surgery were examined. Thirty-three women (48%) had arrhythmias after cardiac surgery with fourteen (20%) requiring implantable cardioverted defibrillators. Two women (6%) with preexisting arrhythmias after cardiac surgery developed postpartum volume overload requiring readmission (p\u2009=\u20090.06). After controlling for age, gestational age at delivery, and BMI, preeclampsia with severe features (p\u2009=\u20090.02) and low birth weight neonates (p\u2009=\u20090.02, aOR = 2.26 [0.56\u20139.03]) remained statistically more like to occur in patients with preexisting cardiac arrhythmias than in patients without preexisting arrhythmias.<\/jats:p><jats:p>\n            Conclusion\u2003Women with a history of open cardiac surgery and preexisting cardiac arrhythmias prior to pregnancy are more likely to develop preeclampsia with severe features and have low birth weight neonates compared with women with a history of open cardiac surgery without preexisting cardiac arrhythmias.<\/jats:p><jats:p>\n            Key Points\n          <\/jats:p>","DOI":"10.1055\/a-1973-7397","type":"journal-article","created":{"date-parts":[[2022,11,9]],"date-time":"2022-11-09T00:22:41Z","timestamp":1667953361000},"page":"811-816","source":"Crossref","is-referenced-by-count":3,"title":["Pregnancy Outcomes in Women with Arrhythmias following Surgical Repair of Cardiac Defects"],"prefix":"10.1055","volume":"40","author":[{"given":"Rebecca","family":"Chornock","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, MedStar Washington Hospital Center, Washington, District of Columbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dana","family":"Lewis","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, MedStar Washington Hospital Center, Washington, District of Columbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephany","family":"Gabaud","sequence":"additional","affiliation":[{"name":"Department of Cardiology, MedStar Washington Hospital Center, Washington, District of Columbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melissa","family":"Fries","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, MedStar Washington Hospital Center, Washington, District of Columbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victoria","family":"Greenberg","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, MedStar Washington Hospital Center, Washington, District of Columbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2438-1699","authenticated-orcid":false,"given":"Tetsuya","family":"Kawakita","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, MedStar Washington Hospital Center, Washington, District of Columbia"},{"name":"Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology, Eastern Virginia Medical School, Norfolk, Virginia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2022,12,26]]},"reference":[{"issue":"01","key":"ref1","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1007\/s13224-016-0841-y","article-title":"Pregnancy after cardiac surgery","volume":"66","author":"A V Kanhere","year":"2016","journal-title":"J Obstet Gynaecol India"},{"issue":"05","key":"ref2","doi-asserted-by":"crossref","first-page":"e320","DOI":"10.1097\/AOG.0000000000003243","article-title":"ACOG Practice Bulletin No. 212: pregnancy and heart disease","volume":"133","author":"American College of Obstetricians and Gynecologists' Presidential Task Force on Pregnancy and Heart Disease and Committee on Practice Bulletins\u2014Obstetrics","year":"2019","journal-title":"Obstet Gynecol"},{"issue":"08","key":"ref3","doi-asserted-by":"crossref","first-page":"2214","DOI":"10.1161\/01.CIR.91.8.2214","article-title":"Atrial arrhythmias in adults after repair of tetralogy of Fallot.
