To examine the association of any type of maternal hypertensive disorders of pregnancy (HDP) and neonatal congenital heart diseases (CHD). We compared the prevalence of CHD between neonates born to mothers with HDP to those delivered to mothers without HDP among 24,525,889 hospital records of living infants, from a national database. We controlled for multiple confounding factors by using multiple logistic regression analysis. Infants delivered to mothers with HDP had higher prevalence of CHD compared to infants born to mothers without HDP [5.20% vs. 1.47%; aOR 2.51(2.38-2.64), p < 0.001]. Maternal diabetes was more frequent among infants born to mothers with HDP and was independently associated with CHD [aOR 5.14 (5.04-5.23), p < 0.001]. Infants born to mothers with hypertension had almost a threefold increase in CHD compared with those born to mothers without hypertension. Further studies are needed to investigate the underlying mechanism and direction of this association. Infants born to mothers with hypertension had almost a threefold increase in CHD compared with those born to mothers without hypertension. Further studies are needed to investigate the underlying mechanism and direction of this association. To investigate the frequency with which neonatal and maternal-fetal medicine (MFM) providers perform joint periviability counseling (JPC), compare content of counseling, and identify perceived barriers to JPC. An anonymous REDCap survey was e-mailed to members of the American Academy of Pediatrics Section on Neonatal-Perinatal Medicine and to members of the Society for MFM. There were 424 neonatal and 115 MFM participants. Fifty-two percent of neonatal and 35% of MFM respondents reported rarely/never performing JPC (p < 0.001), while 80% and 82%, respectively felt it would improve counseling. Content of counseling was similar,
