Abstract
Oculocerebrorenal syndrome (Lowe syndrome) is a rare X-linked disorder affecting 1/500,000 males that most frequently affects the eyes, central nervous system, and kidneys. Phenotypic presentation includes congenital cataracts, developmental delay, intellectual disability, and Fanconi-type renal dysfunction. Lowe Syndrome is caused by hemizygous loss of function variants in the OCRL gene. While individuals may live into the third and fourth decade of life, some will die in the first few years of either renal failure or infection. While early diagnosis is important, few cases have documented the prenatal phenotype of this condition, which has included bilateral cataracts and variable neurological abnormalities. We report a case of a family with an extensive history of congenital cataracts, immune compromise, and neonatal death in male members. The fetus was found to have a unilateral cataract, mild ventriculomegaly, vertebral anomalies, and an underlying diagnosis of Lowe Syndrome with a mutation in OCRL at c.2582-1G>C (IVS23-1G>C).

Abstract
We report a 32-year-old G3P1 at 35 weeks 3 days with a dichorionic, diamniotic twin gestation who presented for evaluation secondary to ventriculomegaly (VM) in one twin. Fetal ultrasound and MRI demonstrated microcephaly, severe VM, compression of the corpus callosum, scalp and nuchal thickening, elongated ears, bilateral talipes, right-sided congenital diaphragmatic hernia (CDH), and loss of normal cerebral architecture, indicative of a prior insult in the affected twin. The co-twin was grossly normal. The family pursued a palliative care pathway for the affected twin and was delivered at 37 weeks and 6 days. The affected twin passed away within the first hour of life due to respiratory compromise. Postmortem trio exome sequencing identified a homozygous likely pathogenic variant in ATP1A2 (c.2439+1G>A). Although this variant is novel, it is predicted to affect the donor split site in intron 17, resulting in a frameshift and complete loss-of-function of the gene. Biallelic loss of function variants in this gene have been reported in seven individuals with multiple anomalies similar to those in the affected twin. However, only one other individual with a possible CDH has been previously reported. Our case suggests that CDH be included in the phenotypic spectrum of this disorder and reports the first frameshift mutation causing this autosomal recessive multiple congenital anomaly syndrome.

Abstract
Clinical features of 22q11.2 microdeletion syndrome (22q11.2DS) are highly variable between affected individuals and frequently include a subset of conotruncal and aortic arch anomalies. Many are diagnosed with 22q11.2DS when they present as a fetus, newborn or infant with characteristic cardiac findings and subsequently undergo genetic testing. The presence of an aortic arch anomaly with characteristic intracardiac anomalies increases the likelihood that the patient has 22q11.2 DS, but those with an aortic arch anomaly and normal intracardiac anatomy are also at risk. It is particularly important to identify the fetus at risk for 22q11.2DS in order to prepare the expectant parents and plan postnatal care for optimal outcomes. Fetal anatomy scans now readily identify aortic arch anomalies (aberrant right subclavian artery, right sided aortic arch or double aortic arch) in the three-vessel tracheal view. Given the association of 22q11.2DS with aortic arch anomalies with and without intracardiac defects, this review highlights the importance of recognizing the fetus at risk for 22q11.2 deletion syndrome with an aortic arch anomaly and details current methods for genetic testing. To assist in the prenatal diagnosis of 22q11.2DS, this review summarizes the seminal features of 22q11.2DS, its prenatal presentation and current methods for genetic testing.

Abstract
BACKGROUND Enlarged cavum septum pellucidum (CSP) and hypoplastic thymus are proposed extra-cardiac fetal markers for 22q11.2 deletion syndrome. We sought to determine if they were part of the fetal phenotype of our cohort of fetuses with 22q11.2 deletion syndrome. METHODS Case-control study of fetuses evaluated from 2016 to 2022. The study group included fetuses with laboratory confirmation of 22q11.2 deletion syndrome. The control group included pregnancies with conotruncal cardiac anomalies with normal microarray as well as structurally normal fetuses with normal microarray. The CSP and thymus were routinely measured during anatomical ultrasound in all patients at their initial visit at 27.1 ± 4.7 weeks. The CSP and thymus measurements were classified as abnormal if they were >95% or <5% for gestational age, respectively. The groups were compared using analysis of variance or Kruskal-Wallis for continuous variables and Fisher's exact test for categorical variables. Logistic regression was performed, and a Receiver Operating Characteristic (ROC) curve was constructed. RESULTS We identified 47 fetuses with 22q11.2 deletion syndrome and compared them to 47 fetuses with conotruncal anomalies and normal microarray and 47 structurally normal fetuses with normal microarray. 51% (24/47) of fetuses with 22q11.2 deletion syndrome had an enlarged CSP compared to 6% (3/47) of fetuses with a conotruncal anomaly and normal microarray and none of the structurally normal fetuses (p < 0.001). Of the fetuses with 22q11.2 deletion syndrome, 83% (39/47) had a hypoplastic or absent thymus compared to 9% (4/47) of the fetuses with a conotruncal anomaly and normal microarray and none of the structurally normal fetuses (p < 0.001). 87% (41/47) of the fetuses with 22q11.2 deletion syndrome had conotruncal cardiac anomalies. Logistic regression revealed that both enlarged CSP and hypoplastic/absent thymus were associated with 22q11.2 deletion syndrome. The area under the ROC curve for the two markers was 0.94. CONCLUSION An enlarged CSP and hypoplastic/absent thymus appear to be part of the fetal phenotype of 22q11.2 deletion syndrome. These markers are associated with conotruncal anomalies in the setting of 22q11.2 deletion syndrome but not in normal controls or fetuses with conotruncal defects and normal microarrays.

Abstract
INTRODUCTION To identify predictors of poor outcomes in monochorionic diamniotic twin (MCDA) pregnancies with selective fetal growth restriction (sFGR) irrespective of the umbilical artery (UA) Doppler abnormalities. METHODS Single center retrospective analysis of MCDA twins diagnosed with sFGR that opted for expectant management between 2010-2021. The presence of any of the following variables in the growth restricted fetus: low amniotic fluid volume (DVP≤2cm), lack of a cycling bladder, absent or reversed flow in the ductus venosus (DV) with atrial contraction and elevated middle cerebral artery peak systolic velocity (MCA-PSV) defined as ≥1.50 multiples of the median was categorized as complicated. sFGR cases were classified as simple in the absence of the above-mentioned variables. RESULTS 63.3% cases qualified as simple and 36.7% were complicated. Intertwin EFW discordance was higher in the complicated category (26% vs 33%, p=0.0002). The median gestational age at delivery was earlier (33 weeks vs 30.5 weeks, p=0.002) and the likelihood of survival was lower in the complicated category (p<0.0001). The likelihood of two survivors to discharge was lower in type I complicated cases (70% in complicated type I versus 97.1% in simple type I, p=0.0003). On logistic regression analysis, an increase in the "complicated" score negatively correlated with two survivors to discharge (p<0.0001). An ROC curve was created, and the AUC was 0.79. Increasing intertwin EFW discordance also decreased the probability of two survivors to discharge. CONCLUSION The presence of oligohydramnios, lack of a cycling bladder, abnormal DV Doppler, and elevated MCA-PSV in the growth restricted fetus is associated with poor perinatal outcomes and a lower likelihood of having two survivors to discharge. The addition of intertwin EFW discordance to these variables helped improve the survival predictability.

Abstract
INTRODUCTION Randomized controlled trials found that fetoscopic endoluminal tracheal occlusion (FETO) resulted in increased fetal lung volume and improved survival for infants with isolated, severe left-sided congenital diaphragmatic hernia (CDH). The delivery room resuscitation of these infants is particularly unique, and the specific delivery room events are largely unknown. The objective of this study was to compare the delivery room resuscitation of infants treated with FETO to standard of care (SOC) and describe lessons learned. METHODS Retrospective single-center cohort study of infants treated with FETO compared to infants who met FETO criteria during the same period but who received SOC. RESULTS FETO infants were more likely to be born prematurely with 8/12 infants born <35 weeks gestational age compared to 3/35 SOC infants. There were 5 infants who required emergent balloon removal (2 ex utero intrapartum treatment and 3 tracheoscopic removal on placental bypass with delayed cord clamping) and 7 with prenatal balloon removal. Surfactant was administered in 6/12 FETO (50%) infants compared to 2/35 (6%) in the SOC group. Extracorporeal membrane oxygenation use was lower at 25% and survival was higher at 92% compared to 60% and 71% in the SOC infants, respectively. CONCLUSION The delivery room resuscitation of infants treated with FETO requires thoughtful preparation with an experienced multidisciplinary team. Given increased survival, FETO should be offered to infants with severe isolated left-sided CDH, but only in high-volume centers with the experience and capability of removing the balloon, emergently if needed. The neonatal clinical team must be skilled in managing the unique postnatal physiology inherent to FETO where effective interdisciplinary teamwork is essential. Empiric and immediate surfactant administration should be considered in all FETO infants to lavage thick airway secretions, particularly those delivered <48 h after balloon removal.

Abstract
Importance Early anhydramnios during pregnancy, resulting from fetal bilateral renal agenesis, causes lethal pulmonary hypoplasia in neonates. Restoring amniotic fluid via serial amnioinfusions may promote lung development, enabling survival. Objective To assess neonatal outcomes of serial amnioinfusions initiated before 26 weeks' gestation to mitigate lethal pulmonary hypoplasia. Design, Setting, and Participants Prospective, nonrandomized clinical trial conducted at 9 US fetal therapy centers between December 2018 and July 2022. Outcomes are reported for 21 maternal-fetal pairs with confirmed anhydramnios due to isolated fetal bilateral renal agenesis without other identified congenital anomalies. Exposure Enrolled participants initiated ultrasound-guided percutaneous amnioinfusions of isotonic fluid before 26 weeks' gestation, with frequency of infusions individualized to maintain normal amniotic fluid levels for gestational age. Main Outcomes and Measures The primary end point was postnatal infant survival to 14 days of life or longer with dialysis access placement. Results The trial was stopped early based on an interim analysis of 18 maternal-fetal pairs given concern about neonatal morbidity and mortality beyond the primary end point despite demonstration of the efficacy of the intervention. There were 17 live births (94%), with a median gestational age at delivery of 32 weeks, 4 days (IQR, 32-34 weeks). All participants delivered prior to 37 weeks' gestation. The primary outcome was achieved in 14 (82%) of 17 live-born infants (95% CI, 44%-99%). Factors associated with survival to the primary outcome included a higher number of amnioinfusions (P = .01), gestational age greater than 32 weeks (P = .005), and higher birth weight (P = .03). Only 6 (35%) of the 17 neonates born alive survived to hospital discharge while receiving peritoneal dialysis at a median age of 24 weeks of life (range, 12-32 weeks). Conclusions and Relevance Serial amnioinfusions mitigated lethal pulmonary hypoplasia but were associated with preterm delivery. The lower rate of survival to discharge highlights the additional mortality burden independent of lung function. Additional long-term data are needed to fully characterize the outcomes in surviving neonates and assess the morbidity and mortality burden.

Abstract
BACKGROUND The rate of polyhydramnios is higher in pregnancies complicated by congenital anomalies. These pregnancies have higher rates of peripartum complications. Amnioreduction is offered to relieve maternal symptoms such as dyspnea, abdominal and respiratory discomfort, and other issues like satiety. OBJECTIVE This study aimed to report the rates of amnioreduction and its associated complications in pregnancies with moderate to severe polyhydramnios secondary to fetal anomalies. We also sought to determine if amnioreduction provided additional benefits, including prolongation of pregnancy and a decrease in the rates of peripartum morbidities associated with moderate to severe polyhydramnios. STUDY DESIGN This was a retrospective review of anomalous singleton pregnancies with moderate to severe polyhydramnios that were evaluated and delivered at a single center between 2013 and 2021. Peripartum outcomes were compared between pregnancies that underwent amnioreduction and those that were expectantly managed. Mann-Whitney U tests were used to compare continuous variables and Fisher's exact tests were used for categorical variables. A multiple regression model was created to understand the effects of amnioreduction on gestational age at delivery. RESULTS A total of 218 singleton pregnancies met the inclusion criteria of moderate to severe polyhydramnios in the study period. Of those, 110 patients (50.5%) underwent amnioreduction and 108 patients (49.5%) opted for expectant management. A total of 147 procedures were performed at a median gestational age of 32.5 weeks and a median of 1900 mL of amniotic fluid was removed per procedure. Complications occurred in 10.9% (n=16) of procedures, including preterm delivery within 48 hours in 5.4% cases (n=8). The median amniotic fluid index was higher in the amnioreduction group than in the expectant group (38.9 cm vs 35.5 cm; P<.0001). Patients who underwent amnioreduction had an earlier median gestational age at delivery (36.3 weeks vs 37.0 weeks; P=.048), however, the rates of spontaneous preterm delivery were similar. A higher percentage of women in the amnioreduction group had vaginal delivery (49.4% vs 30.5%; P=.01) and lower rates of uterine atony (2.4% vs 13.7%; P=.006). In the multiple linear regression analysis, the gestational age at delivery positively correlated with gestational age at amnioreduction after controlling for amniotic fluid volume (P<.0001; 95% confidence interval, 0.34-0.71). In addition, the patients in the amnioreduction group were twice as likely to have a vaginal delivery (P=.02). CONCLUSION Amnioreduction in the setting of moderate-severe polyhydramnios has a reasonably low rate of complications but does not provide any benefits in terms of prolonging the pregnancy. The procedure may increase the likelihood of vaginal delivery and lower the rates of uterine atony.

Abstract
Skeletal dysplasias (SDs) are a heterogeneous group of heritable disorders that affect development of bone and cartilage. Because each SD is individually rare and because of the heterogeneity within and among disorders, prenatal diagnosis of a specific SD remains challenging. Molecular genetic diagnosis involves invasive testing, which some patients are not amenable to. Further, genetic analysis is time consuming, and results may not become available in time to make pregnancy management decisions. Low-dose fetal CT can aid in the prenatal evaluation of SDs. The main downside is the low but true risk of fetal radiation exposure. As such, fetal CT should only be performed when there is concern for a severe skeletal dysplasia and the diagnosis is in question after a detailed US or if molecular genetic testing is unavailable, and when prenatal diagnosis may affect management or counseling. Fetal CT should be obtained after consultation with geneticists, maternal-fetal medicine specialists and fetal radiologists, and sometimes orthopedic surgeons or neonatologists. The purpose of this article is to review the technique of and indications for fetal CT, as well as discuss fetal radiation risk. Illustrative cases will demonstrate when and how CT may be helpful in the diagnosis of SDs.

Abstract
PURPOSE The purpose of the study was to better understand the clinical course and impact of tethered cord release surgery on patients who have previously undergone open spinal dysraphism closure in utero. METHODS This is a single-center retrospective observational study on patients undergoing tethered cord release after having previously had open fetal myelomeningocele (MMC) closure. All patients underwent tethered cord release surgery with a single neurosurgeon. A detailed analysis of the patients' preoperative presentation, intraoperative neuromonitoring (IONM) data, and postoperative course was performed. RESULTS From 2009 to 2021, 51 patients who had previously undergone fetal MMC closure had tethered cord release surgery performed. On both preoperative and postoperative manual motor testing, patients were found to have on average 2 levels better than would be expected from the determined anatomic level from fetal imaging. The electrophysiologic functional level was found on average to be 2.5 levels better than the anatomical fetal level. Postoperative motor levels when tested on average at 4 months were largely unchanged when compared to preoperative levels. Unlike the motor signals, 46 (90%) of patients had unreliable or undetectable lower extremity somatosensory evoked potentials (SSEPs) prior to the tethered cord release. CONCLUSION Tethered cord surgery can be safely performed in patients after open fetal MMC closure without clinical decline in manual motor testing. Patients often have functional nerve roots below the anatomic level. Sensory function appears to be more severely affected in patients leading to a consistent motor-sensory imbalance.

Abstract
BACKGROUND Selective cord occlusion is an option in complicated monochorionic multiple gestations with the goal of reducing the pregnancy by one fetus and to optimize the outcomes for the remaining fetus(es). OBJECTIVE This study aimed to determine the rate and associated risk factors of dual demise in complex monochorionic pregnancies after selective cord occlusion via radiofrequency ablation. STUDY DESIGN This was a single-center analysis of a prospective registry cohort of complex monochorionic pregnancies managed with selective cord occlusion via radiofrequency ablation between 2014 and 2021. A total of 167 pregnancies met the inclusion criteria and were evaluated on the basis of the intended outcome of dual demise vs singleton survival. Risk factors were compared between the 2 groups. The Mann-Whitney U test was used for continuous variables and the Fisher exact test was used for categorical variables. RESULTS The incidence of postprocedure dual demise within the first week after performing radiofrequency ablation was 10.8% (18/167). The risk was higher in pregnancies undergoing radiofrequency ablation for discordant anomaly, and this subcategory constituted 38.9% of pregnancies in the dual demise subgroup (P=.02). Lower intertwin estimated fetal weight discordance (P=.01) was associated with dual demise. Perioperative variables including gestational age at procedure, placental cord insertion distance, operative time, and radiofrequency ablation time were similar in those with and without dual demise. CONCLUSION Our results show that selective cord occlusion via radiofrequency ablation is a safe and reasonable option in complicated monochorionic pregnancies, with low rates of dual demise within the first week after the procedure.

Abstract
The field of fetal therapy has so far escaped from formal accreditation and quality control. Despite that, current published evidence shows that outcomes of interventions in younger fetal therapy centers are similar to what is achieved in more experienced centers and outcomes of interventions have improved over time. The question however remains what is not being published and what should be the standard of care, given the lack of level 1 evidence from randomized controlled trials for many interventions. Formal collaborative networks such as NAFTnet and others allow for anonymized benchmarking of center outcomes, without publicly shaming (and financially punishing) underperforming centers. Large registries also allow for tracking of rare complications and may result in improved patient outcomes over time. Core outcome sets, which could serve as a basis for outcome reporting, are available for some conditions, but certainly not for all, resulting in communication difficulties between centers. Formal accreditation, quality control, and outcome reporting are hard to implement, expensive, and may result in decreasing access to care by pushing smaller centers out of the market. Despite the existing difficulties, international societies have committed to quality improvement, and fetal therapy programs are strongly recommended to participate in voluntary outcome tracking.

Abstract
INTRODUCTION The aim of the study was to determine if markers of donor placental insufficiency and recipient cardiac dysfunction increase the risk for single fetal demise (SFD) after laser for twin-twin transfusion syndrome (TTTS). METHODS Single-center retrospective review of patients who had laser for TTTS. Risk factors for donor and recipient demise within 1 week were compared in pregnancies with SFD and pregnancies with dual survival using χ2 or Fisher's exact test. Multivariate logistic regression was then performed. RESULTS Of 398 procedures, 305 (76.6%) had dual survival, 36 (9.0%) had donor demise, 28 (7.0%) had recipient demise, and 9 (2.3%) had dual demise. The remaining 20 (5.0%) patients had complicated courses with pregnancy loss or further intervention. In the 64 pregnancies with SFD, 29 (81%) in the donor group and 20 (71%) in the recipient group occurred in the first postoperative week. For the donor demise group, estimated fetal weight (EFW) <10%, EFW <3%, EFW <1%, EFW discordance >25%, and EFW discordance >30% did not increase the risk for donor demise except in cases that also had umbilical artery absent or reversed end diastolic flow (AREDF). Donor AREDF was the only independent risk factor for early donor demise. For the recipient demise group, recipient abnormal venous Dopplers were associated with increased risk while EFW discordance >25% was associated with decreased risk of recipient loss. DISCUSSION/CONCLUSION In our cohort, donor growth restriction did not increase the risk of early donor demise after laser unless there was also donor AREDF. Donor AREDF was an independent risk factor for donor demise likely due to the severity of placental insufficiency. Abnormal recipient venous Doppler indices increased the risk of early recipient loss while a large intertwin discordance decreased the risk. This may be explained by profound overload in cases with recipient abnormal venous Doppler velocimetry and a lower risk of substantial fluid shifts from a relatively smaller donor territory when there is a large discordance.

Abstract
INTRODUCTION We sought to determine if maternal obesity, defined by BMI 30-34.9 or BMI 35, negatively impacts the technical aspects and pregnancy outcomes in women treated with selective laser photocoagulation of placental communicating vessels for twin-twin transfusion syndrome (TTTS). METHODS Retrospective review of women undergoing laser for TTTS from January 2010 - December 2021. Outcomes were stratified based on maternal BMI < 30, 30-34.9 and > 35. Data obtained included maternal age, parity, ethnicity, gestational age at laser, placental location, Quintero stage and CHOP cardiovascular score, operative and anesthesia times, procedure to delivery interval, gestational age at delivery, survival to birth, survival to discharge, and presence of residual anastomoses. Statistical analysis included chi-square or Fisher's exact test for categorical variables and Mann Whitney U test for continuous variables with p<.05 being significant. RESULTS A total of 434 women underwent laser for TTTS during the study period. Of those, 274 (63%) had a BMI of < 30, 92 (21.2%) had a BMI between 30-34.9, and 68 (15.7%) had a BMI > 35. There were no differences in maternal age, parity or ethnicity, Quintero stage, CHOP cardiovascular score, placental location, operative time, laser to delivery interval, gestational age at delivery, survival outcomes, or presence of residual anastomoses between the three groups. Patients with BMI of 30-34.9 were operated on at a slightly later gestational age and those with BMI > 35 had longer operative and anesthesia times. There were no technical failures as a result of BMI > 30 or 35. DISCUSSION/CONCLUSION Using appropriate technical adjustments, outcomes for obese women undergoing laser for TTTS are similar to non-obese women although patients with BMI > 35 have longer operative and anesthesia times.

Abstract
Fetal therapies undertaken to improve fetal outcome or to optimize transition to neonate life often entail some level of maternal, fetal, or neonatal risk. A fetal therapy center needs access to resources to carry out such therapies and to manage maternal, fetal, and neonatal complications that might arise, either related to the therapy per se or as part of the underlying fetal or maternal condition. Accordingly, a fetal therapy center requires a dedicated operational infrastructure and necessary resources to allow for appropriate oversight and monitoring of clinical performance and to facilitate multidisciplinary collaboration between the relevant specialties. Three care levels for fetal therapy centers are proposed to match the anticipated care complexity, with appropriate resources to achieve an optimal outcome at an institutional and regional level. A level I fetal therapy center should be capable of offering fetal interventions that may be associated with obstetric risks of preterm birth or membrane rupture but that would be very unlikely to require maternal medical subspecialty or intensive care, with neonatal risks not exceeding those of moderate prematurity. A level II center should have the incremental capacity to provide maternal intensive care and to manage extreme neonatal prematurity. A level III therapy center should offer the full range of fetal interventions (including open fetal surgery) and be able manage any of the associated maternal complications and comorbidities, as well as have access to neonatal and pediatric surgical intervention including indicated surgery for neonates with congenital anomalies.

Abstract
BACKGROUND Neurologic injury in the surviving twin is a risk after single fetal demise in a monochorionic pregnancy. OBJECTIVE This study aimed to describe fetal magnetic resonance neuroimaging findings in pregnancies complicated by single fetal demise after laser photocoagulation for twin-twin transfusion syndrome. STUDY DESIGN This was a single-center retrospective analysis of a cohort of prospectively collected patients in a monochorionic twin registry who had fetoscopic laser photocoagulation for twin-twin transfusion syndrome with single fetal demise at follow-up. Magnetic resonance neuroimaging was offered 3 to 4 weeks after the demise to assess for potential neurologic sequelae. Magnetic resonance images were interpreted by 2 board-certified neuroradiologists and classified as normal, mildly abnormal, or severely abnormal. The groups were compared on the basis of recipient vs donor demise using the Fisher exact test and Mann-Whitney U test. Multivariate logistic regression was performed to determine risk factors for abnormal magnetic resonance neuroimaging. RESULTS In 378 laser photocoagulation procedures, 64 cases (16.9%) of single demise were identified (36 in the donor group and 28 in the recipient group). Of note, 6 patients had rupture of membranes with nonviable delivery (3 from each group). Moreover, 40 patients (69%) underwent magnetic resonance imaging. Of those patients, 12 (30%) had abnormal findings: 10 (83%) were associated with mild changes, and 2 (17%) were associated with severe findings. Abnormal magnetic resonance neuroimaging was seen in 3 of 22 patients (14%) after donor demise and 9 of 18 patients (50%) after recipient demise (P=.02). Logistic regression revealed that recipient vs donor demise was an independent risk factor for abnormal magnetic resonance imaging. In addition, 2 pregnancies with severe magnetic resonance imaging findings had complicated courses. CONCLUSION Mildly abnormal magnetic resonance neuroimaging findings were common after laser photocoagulation for twin-twin transfusion syndrome complicated by single fetal demise and were more common in cases of recipient demise than donor demise. Severe magnetic resonance neuroimaging findings in this series were limited to patients with complicated peri- or postoperative courses.

Abstract
BACKGROUND Children with single ventricle heart disease have significant morbidity and mortality. The maternal–fetal environment (MFE) may adversely impact outcomes after neonatal cardiac surgery. We hypothesized that impaired MFE would be associated with an increased risk of death after stage 1 Norwood reconstruction. METHODS AND RESULTS We performed a retrospective cohort study of children with hypoplastic left heart syndrome (and anatomic variants) who underwent stage 1 Norwood reconstruction between 2008 and 2018. Impaired MFE was defined as maternal gestational hypertension, preeclampsia, gestational diabetes, and/or smoking during pregnancy. Cox proportional hazards regression models were used to investigate the association between impaired MFE and death while adjusting for confounders. Hospital length of stay was assessed with the competing risk of in‐hospital death. In 273 children, the median age at stage 1 Norwood reconstruction was 4 days (interquartile range [IQR], 3–6 days). A total of 72 children (26%) were exposed to an impaired MFE; they had more preterm births (18% versus 7%) and a greater percentage with low birth weights <2.5 kg (18% versus 4%) than those without impaired MFE. Impaired MFE was associated with a higher risk of death (hazard ratio [HR], 6.05; 95% CI, 3.59–10.21; P<0.001) after adjusting for age at surgery, Hispanic ethnicity, genetic syndrome, cardiac diagnosis, surgeon, and birth era. Children with impaired MFE had almost double the risk of prolonged hospital stay (HR, 1.95; 95% CI, 1.41–2.70; P<0.001). CONCLUSIONS Children exposed to an impaired MFE had a higher risk of death following stage 1 Norwood reconstruction. Prenatal exposures are potentially modifiable factors that can be targeted to improve outcomes after pediatric cardiac surgery.

Abstract
INTRODUCTION Uterine incision based on placental location in open maternal-fetal surgery (OMFS) has never been evaluated in regards to maternal or fetal outcomes. OBJECTIVE To investigate whether an anterior placenta was associated with increased rates of intraoperative, perioperative, antepartum, obstetric, or neonatal complications in mothers and babies who underwent OMFS for myelomeningocele (fMMC) closure. METHODS Data from the international multi-center prospective registry of patients who underwent OMFS for fMMC closure (fMMC Consortium Registry, 12/15/2010-7/31/2019) was used to compare fetal and maternal outcomes between anterior and posterior placental locations. RESULTS Placental location for 623 patients was evenly distributed between anterior (51%) or posterior (49%). Intraoperative fetal bradycardia (8.3% vs 3.0%, p=0.005) and performance of fetal resuscitation (3.6% vs 1.0%, p=0.034) occurred more frequently in cases with an anterior placenta when compared to those with a posterior placenta. Obstetric outcomes including membrane separation, placental abruption, and spontaneous rupture of membranes were not different among the two groups. However, thinning of the hysterotomy site (27.7% vs 17.7%, p=0.008) occurred more frequently in cases of anterior placenta. Gestational age at delivery (p=0.583) and length of stay in the neonatal intensive care unit (p=0.655) were similar between the two groups. Fetal incision dehiscence and wound revision were not significantly different between groups. Critical clinical outcomes including fetal demise, perinatal death, and neonatal death were all infrequent occurrences and not associated with placental location. CONCLUSIONS Anterior placental location is associated with increased risk of intraoperative fetal resuscitation and increased thinning at the hysterotomy closure site. Individual institutional experiences may have varied but the aggregate data from the fMMC Consortium did not show a significant impact on the gestational age at delivery or maternal or fetal clinical outcomes.

Abstract
BACKGROUND A nutmeg lung pattern on magnetic resonance imaging (MRI) is an imaging finding associated with pulmonary lymphangiectasia. However, the prognostic value of the nutmeg lung pattern is unknown. OBJECTIVE To evaluate the clinical associations of nutmeg lung indicating lymphangiectasia on fetal lung MRI and its relationship with early mortality in fetuses with primary and secondary lymphangiectasia. MATERIALS AND METHODS We retrospectively identified all pregnant patients with a fetal MRI performed for indication of evaluating for pulmonary lymphangiectasia from 2006 to 2019. Two readers evaluated the fetal MRIs and interobserver agreement was calculated. Multivariable logistic regression models were performed to estimate the association of the echocardiographic findings and the presence of nutmeg lung. Kaplan-Meier and Cox regression analyses were performed to evaluate association with mortality in the first 30 days of life. Survival analysis was defined as mortality or orthotopic heart transplant at 30 days of age. P<0.05 was considered significant. RESULTS Our sample included 53 fetuses. Forty-seven (89%) had congenital heart disease (CHD) and 6 (11%) were diagnosed postnatally with primary lymphangiectasia. Interobserver agreement was 0.83. Pulmonary vein congestion on echocardiography was the strongest predictor of nutmeg lung (odds ratio [OR]=12.0, P=0.002). Ten fetuses reached the outcome of heart transplantation (n=1) or death (n=9) within the first 30 days of life. In fetuses with CHD, survival of those with nutmeg lung was significantly lower than in those without (P<0.001). Nutmeg lung was an independent risk factor for 30-day mortality (hazard ratio [HR]: 6.1, P=0.01). CONCLUSION Nutmeg lung pattern on fetal MRI is an independent risk factor associated with 30-day mortality in fetuses with CHD.

Abstract
AIM The optimal gestational age (GA) at delivery and mode of delivery (MoD) for pregnancies with fetal congenital diaphragmatic hernia (CDH) is undetermined. The impact of early term (37-38 weeks 6 days) versus full term (39-40 weeks 6 days) and MoD on immediate neonatal outcomes in prenatally diagnosed isolated CDH cases was evaluated. MATERIAL AND METHODS A retrospective chart review of pregnancies evaluated and delivered with the prenatal diagnosis of CDH between July 1, 2008, and December 31, 2018. The primary outcome was survival to hospital discharge. Secondary outcomes included neonatal intensive care unit (NICU) length of stay (LOS), extracorporeal membrane oxygenation (ECMO) requirement and need for supplemental oxygen at day 30 of life. RESULTS A total of 296 patients were prenatally evaluated for CDH and delivered in a single center during the study period. After applying exclusion criteria, data were available on 113 women who delivered early term and 72 women who delivered full term. Survival to hospital discharge was comparable between the 2 groups - 83.2% in the early term versus 93.1% in the full term (p = 0.07; 95% CI of 0.13-1.04). No difference was observed in any other secondary outcomes. MoD was stratified into spontaneous vaginal, induced vaginal, unplanned cesarean and scheduled cesarean delivery with associated neonatal survival rates of 74.2, 90.6, 89.7 and 88.2%, respectively, p = 0.13. The 5-min Apgar score was higher in the elective cesarean group (7.94) followed by the induced vaginal delivery group (7.8) compared to 7.17 and 7.18 in the spontaneous vaginal and unplanned cesarean groups, respectively (p = 0.03). The GA and MoD did not influence survival to hospital discharge nor NICU LOS in multivariate analysis. CONCLUSIONS Though there were no significant differences in neonatal outcomes for early term compared to full term deliveries of CDH neonates, a trend toward improved survival rates and lower ECMO requirements in the full term group may suggest an underlying importance GA at delivery. Further studies are warranted to validate these findings.

BACKGROUND The effect of modifications in fetal myelomeningocele (fMMC) closure techniques has not been extensively studied. OBJECTIVE To study the effect of a modified closure technique on fMMC postnatal patient outcomes: hydrocephalus, hindbrain herniation, and cyst development. METHODS We performed single-center retrospective study of a subset of post-MOMS (Management of Myelomeningocele Study) trial patients who underwent fMMC closure. After January 2015, the fetal myofascial closure technique was modified. Needlepoint monopolar cautery was used to raise dural lined myofascial flaps to create a more robust closure. Outcomes between the pre- and postmodification groups were compared with regard to hindbrain herniation, hydrocephalus, and cyst development. Families who transitioned care to local institutions were contacted via telephone for outcome information. RESULTS From January 2011 to May 2016, data were reviewed from 119 fMMC closure patients. Patients without full follow-up data were excluded from the final analysis. Cerebrospinal fluid diversion was seen in 32 of 74 patients with the standard technique compared to 14 of 45 with the modified closure and was significantly decreased in postmodification when compared to that of the MOMS trial (P = .01). Hindbrain herniation resolution was significantly decreased in both the pre- and postmodification groups compared to that of the MOMS trial (P < .01). Prior to January 2015 with standard closure, 23 cysts required resection whereas no cysts required resection in the modified repair group (P < .01). CONCLUSION Modified myofascial closure for fMMC closure is safe and feasible. The new approach reflects a decreased rate of cyst development requiring surgical resection, and a trend for improved rates of hindbrain herniation and hydrocephalus.

Abstract
Fetal tumors and other dysplastic masses are relatively rare. They are usually the result of failure of differentiation and maturation during embryonic or fetal life; dysplastic lesions may be the consequence of an obstruction sequence. In this review, we present the most commonly encountered tumors and masses seen during fetal life. Imaging characteristics, tumoral organ of origin, and its effect on the surrounding organs and overall fetal hemodynamics are descriptors that must be relayed to the fetal surgeon and maternal fetal medicine expert, in order to institute most accurate parental counseling and appropriate perinatal treatment plan.

Abstract
Lymphangiectasias are lymphatic malformations characterized by the abnormal dilation and morphology of the lymphatic channels. The classification and treatment of these disorders can be challenging given the limited amount of literature available in children. Various imaging modalities are used to confirm suspected diagnosis, plan the most appropriate treatment, and estimate a prognosis. Prenatal evaluation is performed using both prenatal US imaging and fetal MRI. These modalities are paramount for appropriate parental counseling and planning of perinatal care. During the neonatal period, chest US imaging is a useful modality to evaluate pulmonary lymphangiectasia because other modalities such as conventional radiography and CT display nonspecific findings. Finally, the recent breakthroughs in lymphatic imaging with MRI have allowed us to better classify lymphatic disorders. Dynamic contrast-enhanced lymphangiography, conventional lymphangiography and percutaneous lymphatic procedures offer static and dynamic evaluation of the central conducting lymphatics in children, with excellent spatial resolution and the possibility to provide treatment. The purpose of this review is to discuss the normal and abnormal development of the fetal lymphatic system and how to best depict it by imaging during the prenatal and postnatal life.

Abstract
Parents are at heightened risk for perinatal depression, anxiety and traumatic stress after receiving a prenatal diagnosis of a congenital anomaly. Identifying patients at risk and implementing effective support is crucial to optimizing care in this vulnerable population. A multidisciplinary care team with embedded psychosocial support services can be utilized to evaluate and address the needs of pregnant women and their families, not only at the time of diagnosis, but throughout the course of the pregnancy and postpartum period. Provider awareness helps to facilitate expedited referral to psychosocial services to provide comprehensive care to the patient and family unit.

Abstract
Fetal lung lesions include common lesions such as congenital pulmonary airway malformation (CPAM), bronchopulmonary sequestration (BPS) and combined CPAM-BPS hybrid lesions, as well as less common entities including congenital lobar emphysema/obstruction, bronchial atresia, bronchogenic cysts and rare malignant pulmonary lesions such as pleuropulmonary blastoma. Fetal lung lesions occur in approximately 1 in 15,000 live births and are thought to arise from a spectrum of abnormalities related to airway obstruction and malformation, with the lesion type depending on the timing of insult, level of bronchial tree involvement, and severity of obstruction. Lesions vary from small and asymptomatic to large and symptomatic with significant mass effect on surrounding structures. Accurate diagnosis and characterization of these anomalies is crucial for guiding patient counseling as well as perinatal and postnatal management. The goal of this review is to provide an overview of normal fetal lung appearance and imaging features of common and uncommon lesions on both ultrasound and MR imaging, and to discuss key aspects in reporting and evaluating the severity of these lesions.

Abstract
BACKGROUND The Management of Myelomeningocele Study (MOMS) demonstrated that fetal myelomeningocele (fMMC) closure results in improved hydrocephalus and hindbrain herniation when compared to postnatal closure. OBJECTIVE To report on the outcomes of a single institution's experience in the post-MOMS era, with regard to hydrocephalus absence and hindbrain herniation resolution. METHODS A single-center retrospective study of a subset of post-MOMS patients who underwent fetal/postnatal myelomeningocele closure was performed. Primary outcomes included cerebrospinal fluid (CSF) diversion status and hindbrain herniation resolution. Families were contacted via telephone for outcome information if care was transitioned to outside institutions. Univariate/multivariable analyses were performed using several prenatal and postnatal variables. RESULTS From January 2011 to May 2016, data were reviewed from families of 62 postnatal and 119 fMMC closure patients. In the postnatal group, 80.6% required CSF diversion compared to 38.7% fetal cases (P < .01). Hindbrain herniation resolution occurred in 81.5% fetal repairs compared to 32.6% postnatal (P < .01). In the fetal group, fetal/premature neonatal demise occurred in 6/119 (5.0%) patients. There was a 42.0% decrease (95% CI -55.2 to -28.8) and 48.9% increase (95% CI 33.7 to 64.1) in risk difference for CSF diversion and hindbrain herniation resolution, respectively, in the fetal group. On univariate analysis for both groups, prenatal atrial diameter, frontal-occipital horn ratio, and hindbrain herniation resolution were significantly associated with the absence of clinical hydrocephalus. The treatment of hydrocephalus was significantly delayed in the fetal group compared to the postnatal group (10 mo vs 13.8 d). CONCLUSION This study demonstrates the benefits of fMMC closure with regard to CSF dynamics.

Abstract
BACKGROUND Open maternal-fetal surgery for in utero closure of myelomeningocele (MMC) has become an accepted treatment option for prenatally diagnosed open neural tube defects. Historically, this option has been limited to women with BMI < 35 due to concern for increasing complications in patients with obesity. OBJECTIVE The aim of this study was to evaluate maternal, obstetric, and fetal/neonatal outcomes stratified by maternal BMI classification in women who undergo open maternal-fetal surgery for fetal myelomeningocele (fMMC) closure. METHODS A single-center fMMC closure registry was queried for maternal demographics, preoperative factors, fetal surgery outcomes, delivery outcomes, and neonatal outcomes. Data were stratified based on maternal BMI: <30, 30-34.99, and ≥35-40, corresponding to normal weight/overweight, obesity class I, and obesity class II. Statistical analysis was performed using statistical software SAS v.9.4 (SAS Institute Inc., Cary, NC, USA). RESULTS A total of 264 patients were analyzed, including 196 (74.2%) with BMI <30, 54 (20.5%) with BMI 30-34.99, and 14 (5.3%) with BMI ≥ 35-40. Maternal demographics and preoperative characteristics were similar among the groups. Operative time increased with increasing BMI; otherwise, perioperative outcomes were similar among the groups. Obstetric and neonatal outcomes were similar among the groups. CONCLUSION Increasing maternal BMI did not result in a negative impact on maternal, obstetric, and fetal/neonatal outcomes in a large cohort of patients undergoing open maternal-fetal surgery for fMMC closure. Further study is warranted to determine the generalizability of these results.

Abstract
BACKGROUND AND PURPOSE Fetal imaging is crucial in the evaluation of open neural tube defects. The identification of intraventricular hemorrhage prenatally has unclear clinical implications. We aimed to explore fetal imaging findings in open neural tube defects and evaluate associations between intraventricular hemorrhage with prenatal and postnatal hindbrain herniation, postnatal intraventricular hemorrhage, and ventricular shunt placement. MATERIALS AND METHODS After institutional review board approval, open neural tube defect cases evaluated by prenatal sonography between January 1, 2013 and April 24, 2018 were enrolled (n = 504). The presence of intraventricular hemorrhage and gray matter heterotopia by both prenatal sonography and MR imaging studies was used for classification. Cases of intraventricular hemorrhage had intraventricular hemorrhage without gray matter heterotopia (n = 33) and controls had neither intraventricular hemorrhage nor gray matter heterotopia (n = 229). A total of 135 subjects with findings of gray matter heterotopia were excluded. Outcomes were compared with regression analyses. RESULTS Prenatal and postnatal hindbrain herniation and postnatal intraventricular hemorrhage were more frequent in cases of prenatal intraventricular hemorrhage compared with controls (97% versus 79%, 50% versus 25%, and 63% versus 12%, respectively). Increased third ventricular diameter, specifically >1 mm, predicted hindbrain herniation (OR = 3.7 [95% CI, 1.5-11]) independent of lateral ventricular size and prenatal intraventricular hemorrhage. Fetal closure (n = 86) was independently protective against postnatal hindbrain herniation (OR = 0.04 [95% CI, 0.01-0.15]) and postnatal intraventricular hemorrhage (OR = 0.2 [95% CI, 0.02-0.98]). Prenatal intraventricular hemorrhage was not associated with ventricular shunt placement. CONCLUSIONS Intraventricular hemorrhage is relatively common in the prenatal evaluation of open neural tube defects. Hindbrain herniation is more common in cases of intraventricular hemorrhage, but in association with increased third ventricular size. Fetal closure reverses hindbrain herniation and decreases the rate of intraventricular hemorrhage postnatally, regardless of the presence of prenatal intraventricular hemorrhage.

Abstract
Although bereavement programs are a common element of palliative medicine and hospice programs, few maternal-fetal care centers offer universal bereavement outreach services following perinatal loss. In this article, we describe the implementation of a bereavement outreach program at the Center for Fetal Diagnosis and Treatment at the Children's Hospital of Philadelphia. The four primary goals identified when developing the bereavement outreach protocol included: (1) centralize communication for patient tracking when a perinatal loss occurs, (2) provide individualized and consistent resource support for grieving patients and families, (3) identify strategic outreach points throughout the first year post-loss, and (4) instate programmatic improvements in response to feedback from patients and their families. Strategies for establishing standardized follow-up protocols and operationalizing methods to address outreach initiatives will be shared, with the primary aim of providing other fetal care centers with a proposed model for perinatal bereavement outreach services.

Abstract
OBJECTIVE To determine whether the presence of a myelomeningocele (MMC) sac and sac size correlate with compromised lower-extremity function in fetuses with open spinal dysraphism. METHODS A radiology database search was performed to identify cases of MMC and myeloschisis (MS) diagnosed prenatally in a single center from 2013 to 2017. All cases were evaluated between 18 and 25 weeks. Ultrasound reports were reviewed for talipes and impaired lower-extremity motion. In MMC cases, sac volume was calculated from ultrasound measurements. Magnetic resonance imaging reports were reviewed for hindbrain herniation. The association of presence of a MMC sac and sac size with talipes and impaired lower-extremity motion was assessed. Post-hoc analysis of data from the multicenter Management of Myelomeningocele Study (MOMS) randomized controlled trial was performed to confirm the study findings. RESULTS In total, 283 MMC and 121 MS cases were identified. MMC was associated with a lower incidence of hindbrain herniation than was MS (80.9% vs 100%; P < 0.001). Compared with MS cases, MMC cases with hindbrain herniation had a higher rate of talipes (28.4% vs 16.5%, P = 0.02) and of talipes or lower-extremity impairment (34.9% vs 19.0%, P = 0.002). Although there was a higher rate of impaired lower-extremity motion alone in MMC cases with hindbrain herniation than in MS cases, the difference was not statistically significant (6.6% vs 2.5%; P = 0.13). Among MMC cases with hindbrain herniation, mean sac volume was higher in those associated with talipes compared with those without talipes (4.7 ± 4.2 vs 3.0 ± 2.6 mL; P = 0.002). Review of the MOMS data demonstrated similar findings; cases with a sac on baseline imaging had a higher incidence of talipes than did those without a sac (28.2% vs 7.5%; P = 0.007). CONCLUSIONS In fetuses with open spinal dysraphism, the presence of a MMC sac was associated with fetal talipes, and this effect was correlated with sac size. The presence of a larger sac in fetuses with open spinal dysraphism may result in additional injury through mechanical stretching of the nerves, suggesting another acquired mechanism of injury to the exposed spinal tissue.

Abstract
Fetal tumors represent an infrequent pathology when compared to congenital malformations, although their true incidence may be underestimated. A variety of benign and malignant neoplasms may occur anywhere in the neural axis. Imaging plays an important role in the fetal tumor diagnosis and evaluation of their resultant complications. Discovery of a fetal mass on obstetric ultrasound necessitates further evaluation with prenatal magnetic resonance imaging (MRI). New MR sequences and new applications of existing techniques have been successfully implemented in prenatal imaging. A detailed assessment may be performed using a variety of MR. Fetal tumors may be histologically benign or malignant, but their prognosis generally remains poor, especially for intracranial lesions. Unfavorable tumor location or heightened metabolic demands on a developing fetus may result in severe complications and a fatal outcome, even in cases of benign lesions. Nowadays, prenatal treatment focuses mainly on alleviation of secondary complications caused by the tumors. In this article we review congenital tumors of the brain, face, and neck encountered in prenatal life, and discuss diagnostic clues for appropriate diagnosis.

Abstract
AIM To describe perinatal outcomes of fetuses with a prenatal diagnosis of a concomitant lung lesion in the setting of congenital diaphragmatic hernia (CDH) and to compare outcomes with an isolated CDH control group without a lung lesion, matched by ultrasound-based prognostic markers including presence of liver herniation and lung measurements. MATERIAL AND METHODS This was a retrospective case-control study, wherein all pregnancies diagnosed with CDH and concomitant lung lesions were identified between July 1, 2008, and December 31, 2018. For each case, 2 controls with isolated CDH from the same study period were selected after matching for the presence of liver herniation into the thoracic cavity and ultrasound-based lung measurements either observed over expected lung-to-head ratio (LHR) or absolute LHR with their corresponding gestational age. The outcomes analyzed in the 2 groups included survival to hospital discharge, neonatal intensive care unit (NICU) length of stay (LOS), extracorporeal membrane oxygenation (ECMO) requirement and need for supplemental oxygen (O2) at day 30 of life. RESULTS A total of 21 pregnancies were identified with CDH and a concomitant lung lesion in the study period. All the lung lesions were stratified into a "low-risk category" with a congenital cystic adenomatoid malformation volume ratio of less than 1.0 at the time of presentation. None of these fetuses developed hydrops or required in utero intervention. Overall survival in the group was 80.7% (17/21) and rate of ECMO was 38.1%. Causes of mortality included pulmonary insufficiency, sepsis, renal failure, and bowel infarction. Upon comparison between the cases and controls, the 2 groups were similar with respect to pregnancy demographics. There were no fetal demises in either group. Outcomes including survival rate, NICU LOS, ECMO requirements and need for supplemental O2 at day 30 of life, were comparable among the 2 groups. CONCLUSIONS In our descriptive series, the presence of a concomitant, low-risk lung lesion in the setting of fetal CDH did not have a significant impact on the natural course of the disease, nor was it associated with a worse prognosis.

Abstract
BACKGROUND Infants with congenital diaphragmatic hernia (CDH) often experience hypoxaemia with acidosis immediately after birth. The traditional approach in the delivery room is immediate cord clamping followed by intubation. Initiating resuscitation prior to umbilical cord clamping (UCC) may support this transition. OBJECTIVES To establish the safety and feasibility of intubation and ventilation prior to UCC for infants with CDH. To compare short-term outcomes between trial participants and matched controls treated with immediate cord clamping before intubation and ventilation. DESIGN Single-arm, single-site trial of infants with CDH and gestational age ≥36 weeks. Infants were placed on a trolley immediately after birth and underwent intubation and ventilation, with UCC performed after qualitative CO2 detection. The primary feasibility endpoint was successful intubation prior to UCC. Prespecified safety and physiological outcomes were compared with historical controls matched for prognostic variables using standard bivariate tests. RESULTS Of 20 enrolled infants, all were placed on the trolley, and 17 (85%) infants were intubated before UCC. The first haemoglobin and mean blood pressure at 1 hour of life were significantly higher in trial participants than controls. There were no significant differences between groups for subsequent blood pressure values, vasoactive medications, inhaled nitric oxide or extracorporeal membrane oxygenation. Blood gas and oxygenation index values did not differ between groups at any point. CONCLUSIONS Intubation and ventilation prior to UCC is safe and feasible among infants with CDH. The impact of this approach on clinically relevant outcomes deserves investigation in a randomised trial.

Abstract
The model of group prenatal care was initially developed to include peer support and to improve education and health-promoting behaviors during pregnancy. This model has since been adapted for populations with unique educational needs. Mama Care is an adaptation of the CenteringPregnancy Model of prenatal care. Mama Care is situated within a national and international referral center for families with prenatally diagnosed fetal anomalies. In December 2013, the Center for Fetal Diagnosis and Treatment at Children's Hospital of Philadelphia began offering a model of group prenatal care to women whose pregnancies are affected by a prenatal diagnosis of a fetal anomaly. The model incorporates significant adaptations of CenteringPregnancy in order to accommodate these women, who typically transition their care from community-based settings to the Center for Fetal Diagnosis and Treatment in the late second or early third trimester. Unique challenges associated with caring for families within a referral center include a condensed visit schedule, complex social needs such as housing and psychosocial support, as well as an increased need for antenatal surveillance and frequent preterm birth. Outcomes of the program are favorable and suggest group prenatal care models can be developed to support the needs of patients with prenatally diagnosed fetal anomalies.

Abstract
22q11.2 deletion syndrome (22q11.2DS) is a disorder caused by recurrent, chromosome-specific, low copy repeat (LCR)-mediated copy-number losses of chromosome 22q11. The Children's Hospital of Philadelphia has been involved in the clinical care of individuals with what is now known as 22q11.2DS since our initial report of the association with DiGeorge syndrome in 1982. We reviewed the medical records on our continuously growing longitudinal cohort of 1,421 patients with molecularly confirmed 22q11.2DS from 1992 to 2018. Most individuals are Caucasian and older than 8 years. The mean age at diagnosis was 3.9 years. The majority of patients (85%) had typical LCR22A-LCR22D deletions, and only 7% of these typical deletions were inherited from a parent harboring the deletion constitutionally. However, 6% of individuals harbored other nested deletions that would not be identified by traditional 22q11.2 FISH, thus requiring an orthogonal technology to diagnose. Major medical problems included immune dysfunction or allergies (77%), palatal abnormalities (67%), congenital heart disease (64%), gastrointestinal difficulties (65%), endocrine dysfunction (>50%), scoliosis (50%), renal anomalies (16%), and airway abnormalities. Median full-scale intelligence quotient was 76, with no significant difference between individuals with and without congenital heart disease or hypocalcemia. Characteristic dysmorphic facial features were present in most individuals, but dermatoglyphic patterns of our cohort are similar to normal controls. This is the largest longitudinal study of patients with 22q11.2DS, helping to further describe the condition and aid in diagnosis and management. Further surveillance will likely elucidate additional clinically relevant findings as they age.

Abstract
OBJECTIVE To determine the impact of damaging genetic variation in proangiogenic pathways on placental function, complications of pregnancy, fetal growth, and clinical outcomes in pregnancies with fetal congenital heart defect. STUDY DESIGN Families delivering a baby with a congenital heart defect requiring surgical repair in infancy were recruited. The placenta and neonate were weighed and measured. Hemodynamic variables were recorded from a third trimester (36.4 ± 1.7 weeks) fetal echocardiogram. Exome sequencing was performed on the probands (N = 133) and consented parents (114 parent-child trios, and 15 parent-child duos) and the GeneVetter analysis tool used to identify damaging coding sequence variants in 163 genes associated with the positive regulation of angiogenesis (PRA) (GO:0045766). RESULTS In total, 117 damaging variants were identified in PRA genes in 133 congenital heart defect probands with 73 subjects having at least 1 variant. Presence of a damaging PRA variant was associated with increased umbilical artery pulsatility index (mean 1.11 with variant vs 1.00 without; P = .01). The presence of a damaging PRA variant was also associated with lower neonatal length and head circumference for age z score at birth (mean -0.44 and -0.47 with variant vs 0.23 and -0.05 without; P = .01 and .04, respectively). During median 3.1 years (IQR 2.0-4.1 years) of follow-up, deaths occurred in 2 of 60 (3.3%) subjects with no PRA variant and in 9 of 73 (12.3%) subjects with 1 or more PRA variants (P = .06). CONCLUSIONS Damaging variants in proangiogenic genes may impact placental function and are associated with impaired fetal growth in pregnancies involving a fetus with congenital heart defect.

Abstract
The placenta is a highly vascular structure composed of both maternal and fetal elements. We have determined that damaging variants in genes responsible for the positive regulation of angiogenesis (PRA) (GO:0045766) that are inherited by the fetus impair fetal growth and placental function in pregnancies involving critical congenital cardiac defects (Russell et al., 2019). In this dataset, we present the specific genetic variants identified, describe the parental origin of each variant where possible and present the analyses regarding the potential effects of parental origin of the variant on placental function and fetal growth. The data presented are related to the research article "Damaging variants in pro-angiogenic genes impair growth in fetuses with cardiac defects" (Russell et al., 2019).

Abstract
OBJECTIVES Pregnancies with congenital heart disease in the foetus have an increased prevalence of pre-eclampsia, small for gestational age and preterm birth, which are evidence of an impaired maternal-foetal environment (MFE). METHODS The impact of an impaired MFE, defined as pre-eclampsia, small for gestational age or preterm birth, on outcomes after cardiac surgery was evaluated in neonates (n = 135) enrolled in a study evaluating exposure to environmental toxicants and neuro-developmental outcomes. RESULTS The most common diagnoses were transposition of the great arteries (n = 47) and hypoplastic left heart syndrome (n = 43). Impaired MFE was present in 28 of 135 (21%) subjects, with small for gestational age present in 17 (61%) patients. The presence of an impaired MFE was similar for all diagnoses, except transposition of the great arteries (P < 0.006). Postoperative length of stay was shorter for subjects without an impaired MFE (14 vs 38 days, P < 0.001). Hospital mortality was not significantly different with or without impaired MFE (11.7% vs 2.8%, P = 0.104). However, for the entire cohort, survival at 36 months was greater for those without an impaired MFE (96% vs 68%, P = 0.001). For patients with hypoplastic left heart syndrome, survival was also greater for those without an impaired MFE (90% vs 43%, P = 0.007). CONCLUSIONS An impaired MFE is common in pregnancies in which the foetus has congenital heart disease. After cardiac surgery in neonates, the presence of an impaired MFE was associated with lower survival at 36 months of age for the entire cohort and for the subgroup with hypoplastic left heart syndrome.
