- Abstract
Mirror syndrome (Ballantyne syndrome) is a rare condition characterized by maternal edema, which often affects the lungs. It mirrors the image of fetal and placental edema; therefore, it is also called triple edema. We present the case of a 37-year-old secundigravida, referred to our clinic at 26 weeks of a pregnancy complicated by fetal dilatative restrictive cardiomyopathy and hydrops, placentomegaly, new-onset dyspnea, and maternal calf edema. Due to worsening mirror syndrome, preterm labor was induced. Labor was complicated, with soft tissue dystocia, stillbirth, and postpartum hemorrhage. The first pregnancy was also complicated by fetal right ventricular noncompaction dilatative cardiomyopathy. A eutrophic male child was born vaginally at term and died due to deterioration of the cardiac disease in the third year of life. Next-generation sequencing panel for pediatric cardiology was performed in the deceased child and parents. Two gene variants were recorded: MYOM1: c.770_771delCA (p.Thr257fs) and TPM1: c.814G>A (p.Glu272Lys). Both variants were classified as variants of uncertain significance. This case emphasizes the importance of antenatal counseling, the timing of labor induction, appropriate management of possible complications such as postpartum hemorrhage and soft tissue dystocia, and the interpretation of placental biomarkers in the context of mirror syndrome. Finally, it contributes to understanding the clinical significance of the MYOM1 and TPM1 gene variants., (© 2024.

- Abstract
In the delivery room, fetal well-being is evaluated through laboratory tests, biosignals like cardiotocography, and imaging techniques such as fetal echocardiography. We have developed a multimodal machine learning model that integrates medical records, biosignals, and imaging data to predict fetal acidosis, using a dataset from a tertiary hospital's delivery room (n=2,266). To achieve this, features were extracted from unstructured data sources, including biosignals and imaging, and then merged with structured data from medical records. The concatenated vectors formed the basis for training a classifier to predict post-delivery fetal acidosis. Our model achieved an Area Under the Receiver Operating Characteristic curve (AUROC) of 0.752 on the test dataset, demonstrating the potential of multimodal models in predicting various fetal outcomes.

- Abstract
Objective: To identify new parameters predicting fetal acidemia., Methods: A retrospective case-control study in a cohort of deliveries from a tertiary referral hospital-based cohort deliveries in Zaragoza, Spain between 2018 and 2021 was performed. To predict fetal acidemia, the NICHD categorizations and non-NICHD parameters were analyzed in the electronic fetal monitoring (EFM). Those included total reperfusion time, total deceleration area and the slope of the descending limb of the fetal heart rate of the last deceleration curve. The accuracy of the parameters was evaluated using the specificity for (80%, 85%, 90%, 95%) sensitivity and the area under the receiver operating characteristic curve (AUC)., Results: A total of 10 362 deliveries were reviewed, with 224 cases and 278 controls included in the study. The NICHD categorizations showed reasonable discriminatory ability (AUC = 0.727). The non-NICHD parameters measured during the 30-min fetal monitoring, total deceleration area (AUC = 0.807, 95% CI: 0.770, 0.845) and total reperfusion time (AUC = 0.750, 95% CI: 0.707, 0.792), exhibited higher discriminatory ability. The slope of the descending limb of the fetal heart rate of the last deceleration curve had the best AUC value (0.853, 95% CI: 0.816, 0.889). The combination of total deceleration area or total reperfusion time with the slope demonstrated high discriminatory ability (AUC = 0.908, 95% CI: 0.882, 0.933; specificities of 71.6% and 72.7% for a sensitivity of 90%)., Conclusions: The slope of the descending limb of the fetal heart rate of the last deceleration curve is the strongest predictor of fetal acidosis, but its combination with the total reperfusion time shows better clinical utility., (© 2024 The Authors.

- Abstract
Congenital LQTS is an often undetected inherited cardiac channel dysfunction and can be a reason for intrauterine fetal demise. It can present in utero as CTG and ultrasound abnormalities, i. e., bradycardia, ventricular tachycardia, or fetal hydrops. Diagnosis is made by CTG, echocardiography, or fMCG. Intrauterine therapy with a ß blocker and i. v. magnesium should be started. Our objective was to examine the current knowledge about diagnosis and treatment of LQTS and in particular to highlight the opportunity of vaginal birth under continuous intravenous magnesium therapy. Therefore, a thorough MEDLINE and Google Scholar search was conducted. Randomized controlled trials, meta-analyses, prospective and retrospective cohort trials, and case reports were considered. We showed the possibility of vaginal delivery under continuous magnesium therapy in a case of suspected fetal LQTS. A stepwise concept for diagnosis, monitoring, and peripartum management in low, intermediate, and high risk cases of fetal LQTS is presented. If risk is low or intermediate, a vaginal delivery under continuous monitoring is reasonable. Induction of labor at term should be evaluated., Competing Interests: The authors declare that they have no conflict of interest., (Thieme. All rights reserved.)

- Abstract
Fetal autoimmune atrioventricular block (AVB) is a rare but potentially life-threatening condition. It results from the passage of maternal anti-SSA/Ro or Anti SSB/La auto-antibodies into the fetal circulation, leading to inflammation and fibrosis of the AV node and often to irreversible damage. Besides AVB, these antibodies can also cause cardiomyopathies, but there is no evidence linking them to tachyarrhythmias. We present the case of a patient with significant risk factors for fetal AVB: a prior history of hydrops fetalis , high anti-SSA/Ro antibody levels and hypothyroidism. In this case, the use of dexamethasone and intravenous immunoglobulin may have contributed to reversing the first-degree atrioventricular block detected at 19 weeks of gestation. Additionally, at 21 weeks, the fetus developed a tachyarrhythmia that needed treatment with flecainide. Soon after the birth, the newborn underwent ECG Holter and Wolff-Parkinson-White Syndrome (WPWS) was diagnosed. To our knowledge, the coexistence of fetal AVB and WPWS has never been described., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Chícharo, Rebelo, Lopes, Saavedra, Paramés, Araújo, Cruz-Machado, Pinto and Capela.)

- Abstract
With the improvement in the detection of congenital heart disease in fetal life, fetal cardiac interventions are pushing the envelope in hopes of either altering the natural history of disease or improving survival in certain high-risk lesions. These interventions include fetal aortic valvuloplasty for evolving hypoplastic left heart syndrome, fetal atrial septoplasty with or without atrial septal stenting for hypoplastic left heart syndrome and variants with intact or severely restrictive atrial septum, and fetal pulmonary valvuloplasty for severe pulmonary stenosis or pulmonary atresia with intact ventricular septum. This review discusses their indications, technical aspects, and outcomes based on available literature., Competing Interests: Disclosure A.M. Qureshi: Consultant for W.L.

- Abstract
The aim of this study was to evaluate maternal serological status and fetal sonographic findings of Cytomegalovirus (CMV) infection. This is a retrospective study performed at Perinatology Department of Istanbul Başakşehir Çam and Sakura City Hospital. A computerized search was conducted to identify cases who underwent prenatal diagnosis of fetal CMV infection between September 2020 and December 2023. We identified nine cases with fetal CMV infection. The clinical data of the patients, gestational age at the time of diagnosis, serological, sonographic findings, and pregnancy outcomes were analyzed. A computer search of the database was made for the seroprevalance of CMV-IgM and CMV-IgG in our population. The CMV-IgM and IgG results of the 1235 patients who underwent CMV screening in the first trimester between September 2020 and December 2023 were evaluated. Fetal CMV infection was identified in nine patients. None of the 9 cases showed maternal CMV-IgM positivity. Seven of the 9 patients showed high IgG avidity index. Pregnant population had 98 % positivity for CMV-IgG. The evaluation of serologic tests for CMV is not straightforward in the second and third trimester. IgM and IgG avidity should be interpreted with caution in the second and third trimester. In the presence of ultrasound findings suggesting fetal CMV infection and CMV-IgG positivity, invasive diagnostic tests rather than serological test should be discussed with the patient, and non-primary infections should always be considered to minimize overlooked fetal cytomegalovirus infections and missed antiviral treatment opportunity., (© 2024.

- Abstract
Today, prenatal diagnosis of congenital urogenital malformations is mostly dependent on anatomical variations found on imaging. However, these findings can mislead us in telling us when to intervene, and about post-natal prognosis. Since many findings are dependent on multiple assessments, delayed diagnosis can occur, leading to less optimal outcomes compared to early intervention. Analyses of fetal urinary biomarkers have been proposed as a method of finding biological changes that are predictive for diagnosis and prognosis in fetuses at risk of kidney disease. We interviewed a group of researchers that have demonstrated that by combining multiple omics traits extracted from fetal urine, the biological variability found in single omics data can be circumvented. By analyzing multiple fetal urine peptides and metabolites at single time point, the prognostic power of postnatal renal outcome in fetuses with lower urinary tract obstruction is significantly increased. In this interview, we inquired about the technical aspects of the tests, challenges, and limitations the research group have come across, and how they envision the future for multi-omics fetal analysis in the clinic., Competing Interests: Conflict of interest Two last authors are Basic Science editors of the Journal., (Copyright © 2024 The Authors.

- Abstract
Objectives: Fetal and neonatal hyperthyroidism are most commonly seen in patients whose mothers have Graves' disease. Rarely, it can be caused by non-autoimmune conditions. As these conditions are rare, the workup and treatment is not uniform and can lead to persistent symptoms and long-term negative health effects., Case Presentation: This report describes a patient with congenital hyperthyroidism from a toxic adenoma presenting with fetal tachycardia. The patient was initially managed medically after birth, but was eventually treated with thyroidectomy., Conclusions: This case report highlights an additional, important, differential diagnosis for fetal hyperthyroidism when maternal Graves' disease has been ruled out., (© 2024 Walter de Gruyter GmbH, Berlin/Boston.)

- Abstract
Human cytomegalovirus (CMV) is the leading cause of congenital infection worldwide and the most common cause of non-genetic sensorineural hearing loss. As there is no vaccine or other specific intervention to prevent congenital CMV infection, there is a need to identify maternal and congenital infections with sensitive and specific testing as early as possible. There is no widely accepted practice for screening during pregnancy or in all newborns for identification of possible cases of congenital CMV. Currently, screening during pregnancy is limited to those identified as at risk followed by fetal and/or neonatal testing when congenital infection is suspected. This review focuses primarily on the current status of laboratory testing for diagnosis of maternal and congenital CMV infections. Primary maternal infection is best diagnosed using serologic testing, including CMV IgM, IgG, and avidity testing, while fetal infection should be assessed by nucleic acid amplification testing (NAAT) of amniotic fluid. Urine and saliva NAATs are the mainstay for diagnosis of congenital CMV in the first 3 weeks of life. Testing of dried blood spots can be useful for diagnosis of congenital CMV outside of the newborn period. The gaps in knowledge such as the prognostic value of viral loads in various sample types are addressed., Competing Interests: Research Funding to Nationwide Childrens from bioMerieux, Diasorin, Consultant for BioRad, Medscape.

- Abstract
Objective: Whether or not the effects of anemia in the early phase, while the fetuses attempts to increase cardiac output to meet oxygen requirement in peripheral organs, is detrimental to the fetal developing vital organs is little-known. The objective of this is to compare prenatal cardiovascular changes and post-abortal cellular damages in the myocardium as a pumping organ and the brain as a perfused organ between anemic fetuses (using fetal Hb Bart's disease as a study model) in pre-hydropic phase and non-anemic fetuses., Methods: Fetuses affected by Hb Bart's disease and non-anemic fetuses at 16-22 weeks were recruited to undergo comprehensive fetal echocardiography. Cord blood analysis was used to confirm the definite diagnosis of fetal Hb Bart's disease and normal fetuses. Fetal cardiac and brain tissues were collected shortly after pregnancy termination for the determination of oxidative stress and mitochondrial function, including mitochondrial ROS production and mitochondrial membrane changes., Results: A total of 18 fetuses affected by Hb Bart's disease and 13 non-anemic fetuses were recruited. The clinical characteristics of both groups were comparable. The affected fetuses showed a significant increase in cardiac dimensions, cardiac function, cardiac output and brain circulation without deteriorating cardiac contractility and preload. However, in the affected fetuses, mitochondrial dysfunction was clearly demonstrated in brain tissues and in the myocardium, as indicated by a significant increase in the membrane potential change (p-value < 0.001), and a significant increase in ROS production in brain tissues, with a trend to increase in myocardium. The findings indicated cellular damage in spite of good clinical compensation., Conclusion: The new insight is that, in response to fetal anemia, fetal heart increases in size (dilatation) and function to increase cardiac output and blood flow velocity to provide adequate tissue perfusion, especially brain circulation. However, the myocardium and brain showed a significant increase in mitochondrial dysfunction, suggesting cellular damage secondary to anemic hypoxia. The compensatory increase in circulation could not completely prevent subtle brain and heart damage., (© 2024. The Author(s).)

Fetal neurology encompasses the full spectrum of neonatal and child neurology presentations, with complex additional layers of diagnostic and prognostic challenges unique to the specific prenatal consultation. Diverse genetic and acquired etiologies with a range of potential outcomes may be encountered. Three clinical case presentations are discussed that highlight how postnatal phenotyping and longitudinal follow-up are essential to address the uncertainties that arise in utero, after birth, and in childhood, as well as to provide continuity of care., Competing Interests: Declaration of competing interest The authors have no conflicts of interest or funding relevant to this paper., (Copyright © 2024 The Author(s).

- Abstract
As the field of fetal-neonatal neurology has expanded over the past 2 decades with increasingly complex diagnoses, multidisciplinary collaboration with many subspecialties including genetics, neonatology, obstetrics, maternal fetal medicine, surgical sub-specialties, cardiology, radiology, palliative care, and ethics has needed to evolve to strive to offer optimal patient care. While comprehensive care delivery with an inter-disciplinary approach is preferred, there are often barriers based on numerous health disparities especially in resource limited settings. Even in the context of comprehensive care, diagnostic and prognostic uncertainty lead to challenges for providers during fetal neurology consultations. We present a case that highlights advantages of a comprehensive multi-disciplinary team in caring for the medical and social challenges of patients faced with a fetal neurologic diagnosis. Inter-disciplinary training focusing on maternal, fetal, neonatal, and childhood neurodevelopmental course and collaboration among the numerous stakeholders that contribute to fetal neurology practice is needed to provide optimal counseling and care for families faced with a fetal neurological diagnosis., Competing Interests: Declaration of competing interest The authors do not have any conflicts to declare., (Copyright © 2024.

- Abstract
Objective: Fetal megacystis generally presents as suspected lower urinary tract obstruction (LUTO), which is associated with severe perinatal morbidity. Genetic etiologies underlying LUTO or a LUTO-like initial presentation are poorly understood. Our objectives are to describe single gene etiologies in fetuses initially ascertained to have suspected LUTO and to elucidate genotype-phenotype correlations., Methods: A retrospective case series of suspected fetal LUTO positive for a molecular diagnosis was collected from five centers in the Fetal Sequencing Consortium. Demographics, sonograms, genetic testing including variant classification, and delivery outcomes were abstracted., Results: Seven cases of initially prenatally suspected LUTO-positive for a molecular diagnosis were identified. In no case was the final diagnosis established as urethral obstruction that is, LUTO. All variants were classified as likely pathogenic or pathogenic. Smooth muscle deficiencies involving the bladder wall and interfering with bladder emptying were identified in five cases: MYOCD (2), ACTG2 (2), and MYH11 (1). Other genitourinary and/or non-genitourinary malformations were seen in two cases involving KMT2D (1) and BBS10 (1)., Conclusion: Our series illustrates the value of molecular diagnostics in the workup of fetuses who present with prenatally suspected LUTO but who may have a non-LUTO explanation for their prenatal ultrasound findings., (© 2023 John Wiley & Sons Ltd.)

- Abstract
Objective: Fetal Lower Urinary Tract Obstruction (LUTO) is associated with oligohydramnios and significant fetal morbidity, resulting in poor lung development and perinatal death. However, oligohydramnios may develop at different gestational periods, and the impact of timing on fetal outcomes remains unknown. Our objective was to characterize the impact onset of oligohydramnios had on prenatal outcomes., Methods: This study is a retrospective cohort study of all patients with a prenatal diagnosis of LUTO at our tertiary referral center from 2014 to 2023. All patients underwent detailed ultrasonography and interdisciplinary counseling and were subsequently delivered at our institution. Data were obtained from electronic medical records and complete extraction was required for final inclusion., Results: During the study time period, 93 patients met inclusion criteria of which 68 (73.1%) developed oligohydramnios during their pregnancy. 63 (93%) of these pregnancies resulted in livebirths with 28 (41.1%) perinatal deaths. Onset of oligohydramnios was earlier in pregnancies with perinatal death (23 vs. 28 weeks, p = 0.004) and associated with pulmonary hypoplasia., Conclusions: Our data show the impact of oligohydramnios timing in pregnancy on pulmonary hypoplasia and ultimately perinatal death. This allows for detailed patient counseling on the impact oligohydramnios may have on pregnancies by the gestational age of onset., (© 2023 John Wiley & Sons Ltd.)

- Abstract
Introduction: A critical component of an evidence-based reassessment of in-utero intervention for fetal aqueductal stenosis (fetal AS) is determining if the prenatal diagnosis can be accurately made at a gestational age amenable to in-utero intervention., Methods: A multicenter, prospective, observational study was conducted through the North American Fetal Therapy Network (NAFTNet). Pregnancies complicated by severe central nervous system (CNS) ventriculomegaly (lateral ventricle diameter >15 mm) not secondary to a primary diagnosis (myelomeningocele, encephalocele, etc.) were recruited at diagnosis. Imaging and laboratory findings were recorded in an online REDCap database. After evaluation, investigators were asked to render their degree of confidence in the diagnosis of fetal AS. The prenatal diagnosis was compared to the postnatal diagnosis obtained through neonatal neuroimaging. Performance characteristics of ultrasound and magnetic resonance imaging (MRI) were calculated, as was the mean gestational age at diagnosis., Results: Between April 2015 and October 2022, eleven NAFTNet centers contributed 64 subjects with severe fetal CNS ventriculomegaly. Of these, 56 had both prenatal and postnatal diagnoses recorded. Ultrasound revealed 32 fetal AS true positives, 4 false positives, 7 false negatives, and 13 true negatives, rendering a sensitivity of 0.82, a specificity of 0.76, a positive predictive value of 0.89, and a negative predictive value of 0.65. The mean gestational age at diagnosis by ultrasound was 25.5 weeks (std +/- 4.7 weeks). The proportion of agreement (true positive + true negative/n) was highest at 24 weeks gestation. For fetal MRI (n = 35), the sensitivity for fetal AS was 0.95, specificity was 0.69, positive predictive value was 0.84, and negative predictive value was 0.90. MRI was performed at 25 weeks on average., Conclusion: The prenatal diagnosis of fetal AS can be made with accuracy at a gestational age potentially amenable to in-utero intervention. Only 7% of subjects were incorrectly diagnosed prenatally with fetal AS by ultrasound and 11% by MRI. Diagnostic accuracy of fetal AS will likely improve with increased experience., (© 2024 S.

- Abstract
Cytomegalovirus is the most common cause of congenital infectious disease and the leading nongenetic etiology of sensorineural hearing loss. Although most infected neonates are asymptomatic at birth, congenital cytomegalovirus infection is responsible for nearly 400 infant deaths annually in the United States and may lead to significant long-term neurodevelopmental impairments in survivors. The resulting financial and social burdens of congenital cytomegalovirus infection have led many medical centers to initiate targeted testing after birth, with a growing advocacy to advance universal newborn screening. While no cures or vaccines are currently available to eliminate or prevent cytomegalovirus infection, much has been learned over the last five years regarding disease pathophysiology and viral replication cycles that may enable the development of innovative diagnostics and therapeutics. This Review will detail our current understanding of congenital cytomegalovirus infection, while focusing our discussion on routine and emerging diagnostics for viral detection, quantification, and long-term prognostication. IMPACT: This review highlights our current understanding of the fetal transmission of human cytomegalovirus. It details clinical signs and physical findings of congenital cytomegalovirus infection. This submission discusses currently available cytomegalovirus diagnostics and introduces emerging platforms that promise improved sensitivity, specificity, limit of detection, viral quantification, detection of genomic antiviral resistance, and infection staging (primary, latency, reactivation, reinfection)., (© 2023.

- Abstract
Introduction: Cases with early diagnosis of neonatal tuberous sclerosis syndrome (TSC) are relatively seldom seen, and misdiagnosis of intracranial hemorrhage is even more rare. We retrospectively analyzed the clinical data of a case of neonatal tuberous sclerosis with atypical early symptoms and misdiagnosed as more common intracranial hemorrhage of the newborn., Patient Concerns: The child was female and had no obvious cause of convulsion 12 days after birth. The local hospital was initially diagnosed as "neonatal intracranial hemorrhage, congenital heart disease," and still had convulsions after 5 days of treatment, so it was transferred to neonatal intensive care unit of our hospital., Diagnosis: After admission, cardiac color ultrasound, magnetic resonance imaging, and electroencephalogram were performed, and TSC was diagnosed in combination with clinical symptoms. However, no known pathogenic mutations such as TSC1 and TSC2 were detected by peripheral blood whole exon sequencing., Intervention: After a clear diagnosis, sirolimus, and vigabatrin were given. But there were still convulsions. Topiramate, valproic acid, and oxcarbazepine were successively added to the outpatient department for antiepileptic treatment, and vigabatrin gradually decreased., Outcome: Up to now, although the seizures have decreased, they have not been completely controlled., Conclusions: The TSC of neonatal tuberous sclerosis is different from that of older children. It is usually characterized by respiratory distress and arrhythmia, and may be accompanied by convulsions, but the activity between attacks is normal. However, neonatal intracranial hemorrhage can be caused by premature delivery, birth injury, hypoxia, etc. Its characteristics are acute onset, severe illness, and rapid progression. Consequently, the diagnosis of these 2 diseases should not only be based on medical imaging, but also be combined with their clinical characteristics. When the imaging features are inconsistent with the clinical diagnosis, a comprehensive evaluation should be made again. The timing and pattern of onset of neonatal convulsions can help in differential diagnosis. If there is cardiac rhabdomyoma, subependymal or cortical nodule, skin low melanoma, etc, the possibility of neonatal TSC should be considered, and the diagnosis should be made according to its diagnostic criteria to avoid or reduce misdiagnosis., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2023 the Author(s).

- Abstract
Background: This study aimed to evaluate the value of non-invasive prenatal testing (NIPT) in the prenatal screening of foetal aneuploidy-associated diseases at different gestational ages., Methods: Briefly, cell-free foetal DNAs were extracted from plasma first, followed by DNA sequencing and bioinformatics analyses for chromosome aneuploidy (T21, T18, and T13), sex chromosome aneuploidy (SCA), and microdeletion/microduplication. Subsequently, the positive results were subject to karyotype analyses., Results: The pregnant women included in this study were divided into six groups, and the results, such as chromosome diagnoses, and clinical phenotypes, were collected for data analyses. According to the results of the data analysis, the positivity rates of foetal chromosomal abnormalities in pregnant women under 20, 20-24, 25-29, 30-34, 35-39, and >40 years old were 0%, 0.17%, 0.25%, 0.27%, 0.60%, and 1.66%, respectively. The positive predictive value (PPV) in the 20-24 years group was 41.67%, that in the 25-29 years group was 62.5%, that in the 30-34 years group was 66.67%, that in the 35-39 years group was 90.74%, and that in the >40 years group was 90.32%., Conclusion: Overall, NIPT detection in elderly pregnant women has excellent clinical application value in reducing the incidence of either birth defects or abortion caused by invasive chromosome examination.

- Abstract
Objectives: The current recommended treatment for severe fetal anemia is in utero transfusion (IUT). During this procedure, the evaluation of the necessary volume of transfused blood is based on regular measurement of fetal hemoglobin (FHb) concentration. The gold standard measurement is performed in the biology laboratory. A rapid medical test such as HemoCue
® is an effective way to predict FHb concentration. It would reduce the time to obtain results and therefore the procedure duration. To evaluate the accuracy of HemoCue® to measure FHb during IUT, we compared Hb levels obtained by HemoCue® and by our biology laboratory., Methods: This retrospective study involved all pregnant women who had undergone an IUT in the university hospital of Clermont-Ferrand, France, during the period from 1 January 2010 to 6 June 2021. The FHb level was evaluated by two methods, a rapid medical test, HemoCue® , and a standard method in the biology laboratory., Results: We obtained 244 pairs of results from HemoCue® and our laboratory, of 90 IUT procedures. The correlation between the two sets of results was excellent, with Lin's concordance correlation coefficient of 0.979. However, we established that the measurements were not significantly modified by IUT number, puncture time, cause of fetal anemia, estimated fetal weight, gestational age, and delay between two IUT or middle cerebral artery peak systolic velocity values., Conclusion: Our results allowed to extend the relevance of FHb measurements by HemoCue® during IUT.- Published

- Abstract
Aim: The aim of this study was to describe the unique experiences of parents facing a Life Limiting Fetal Conditions (LLFC) diagnosis, who chose to continue with their pregnancy, as they prepare for childbirth through individual and group prenatal education., Design: A qualitative study., Methods: We employed the phenomenological approach and the Colaizzi strategy to analyse semi-structured interviews. Thirteen persons were interviewed. The participants were couples (n = 6) and women (n = 7) who received LLFC and were preparing for birth., Results: We described three main paths of prenatal education chosen by parents with LLFC: 'Searching for normality' concerned people participating in conventional prenatal classes (AC) who tried to avoid confronting the situation they faced; 'Searching for communitas' concerned the participation in special AC selected for the opportunity of sharing experiences; 'Searching for an individual way' concerned people who resorted to individual preparation for childbirth, often as a result of delayed planning. Parents should have a choice of various paths of birth preparation, that best meet their preferences., (© 2023 The Authors. Nursing Open published by John Wiley & Sons Ltd.)

- Abstract
Background: Several studies have shown that the congenital pulmonary airway malformation volume ratio is a useful prognosticator of neonatal outcome in prenatally diagnosed lung lesions. However, there remains a lack of consensus on which congenital pulmonary airway malformation volume ratio values have the best predictive value because of operator dependence, inherent changes in lung lesion size throughout gestation, and the widespread use of maternal steroids., Objective: This study sought to determine the association between serial congenital pulmonary airway malformation volume ratio measurements and neonatal outcomes among fetuses with lung malformations., Study Design: This was a retrospective cohort study of fetuses with a prenatally diagnosed lung malformation managed at 2 major fetal centers from January 2010 to December 2021. Prenatal variables, including prospectively measured congenital pulmonary airway malformation volume ratio measurements (initial, maximum, and final), were analyzed. The results were correlated with 3 outcome measures, namely surgical resection before 30 days of life, a need for supplemental O
2 at birth, and endotracheal intubation at birth. Statistical analyses were performed using receiver operating characteristic curve analyses, Welch 2 sample t tests, and multivariable logistic regressions (P<.05)., Results: There were 123 fetuses with isolated lung lesions identified. Eight (6.5%) had hydrops. The mean initial congenital pulmonary airway malformation volume ratio was 0.67±0.61 cm2 at 22.9±3.9 weeks' gestation. The mean maximum congenital pulmonary airway malformation volume ratio was 1.08 ± 0.94 cm2 at 27.0 ± 4.0 weeks' gestation. The mean final congenital pulmonary airway malformation volume ratio was 0.58±0.60 cm2 at 33.2±4.1 weeks' gestation. At a mean gestational age at delivery of 38.3±2.6 weeks, 15 (12.2%) underwent neonatal lung resection for symptomatic disease. In a multivariable regression, all 3 congenital pulmonary airway malformation volume ratio measurements showed a significant correlation with neonatal lung resection (P<.001). Optimal congenital pulmonary airway malformation volume ratio cutoffs were established based on an initial congenital pulmonary airway malformation volume ratio of ≥0.8 cm2 , maximum congenital pulmonary airway malformation volume ratio of ≥1.5 cm2 , and a final congenital pulmonary airway malformation volume ratio of ≥1.3 cm2 with associated areas under the curve of 0.89, 0.97, and 0.93, respectively. The final congenital pulmonary airway malformation volume ratio had the highest specificity for predicting surgical lung resection in the early postnatal period., Conclusion: Measuring congenital pulmonary airway malformation volume ratios throughout pregnancy in fetuses with pulmonary malformations has clinical value for prenatal counseling and planning care transition after delivery. Fetuses with a final congenital pulmonary airway malformation volume ratio of more than 1.3 cm2 are likely to require neonatal surgery and therefore should be delivered at tertiary care centers with a neonatal intensive care unit and pediatric surgical expertise., (Copyright © 2023 Elsevier Inc.

- Abstract
Objective: Anti-Ro antibody-positive mothers are frequently referred for serial echocardiography due to the fetal risk of developing heart block and endocardial fibroelastosis. Little is known why only some and not all offspring develop these cardiac manifestations of neonatal lupus (CNL). This prospective study examined associations between anti-Ro antibody titers and fetal CNL., Methods: Antibody-positive mothers referred since 2018 for fetal echocardiography at risk of CNL (group 1; n = 240) or with CNL (group 2; n = 18) were included. Maternal antibody titers were measured with a chemiluminescent immunoassay (CIA). Additional testing on diluted serum samples was used to quantify anti-Ro 60 antibody titers above the analytical measuring range (AMR) of the standard CIA (≥1,375 chemiluminescent units [CU])., Results: Among 27 total mothers with a fetal diagnosis of CNL, all displayed anti-Ro 60 antibody titers that exceeded the AMR of the CIA at least 10-fold. Of 122 mothers in group 1 who underwent additional anti-Ro 60 antibody testing, event rates of CNL (n = 9) were 0% (0 of 45) among mothers with anti-Ro 60 antibody titers from 1,375-10,000 CU, 5% (3 of 56) among mothers with titers from 10,000-50,000 CU, but 29% (6 of 21) among mothers with titers >50,000 CU (odds ratio 13.1, P = 0.0008). Of mothers in group 2 with a primary diagnosis of CNL, 0% (0 of 18 mothers) had anti-Ro 60 antibody titers <10,000 CU, 44% (8 of 18 mothers) had titers from 10,000-50,000 CU, and 56% (10 of 18 mothers) had titers >50,000 CU., Conclusion: CNL is associated with substantially higher anti-Ro antibody titers than are obtained using a standard CIA. Enhancing the assay measuring range allows an improved specificity of identifying pregnancies at risk of CNL., (© 2023 American College of Rheumatology.)

- Abstract
After the promulgation of the first edition of expert consensus on the application of chromosomal microarray analysis (CMA) technology in prenatal diagnosis in 2014, after 8 years of clinical and technical development, CMA technology has become a first-line diagnosis technology for fetal chromosome copy number deletion or duplication abnormalities, and is widely used in the field of prenatal diagnosis in China. However, with the development of the industry and the accumulation of experience in case diagnosis, the application of CMA technology in many important aspects of prenatal diagnosis, such as clinical diagnosis testimony, data analysis and genetic counseling before and after testing, needs to be further standardized and improved, so as to make the application of CMA technology more in line with clinical needs. The revision of the guideline was led by the National Prenatal Diagnostic Technical Expert Group, and several prenatal diagnostic institutions such as Peking Union Medical College Hospital were commissioned to write, discuss and revise the first draft, which was discussed and reviewed by all the experts of the National Prenatal Diagnostic Technical Expert Group, and was finally formed after extensive review and revision. This guideline is aimed at the important aspects of the application of CMA technology in prenatal diagnosis and clinical diagnosis, from the clinical application of evidence, test quality control, data analysis and interpretation, diagnosis report writing, genetic counseling before and after testing and other work specifications are elaborated and introduced in detail. It fully reflects the integrated experience, professional thinking and guidance of the current Chinese expert team on the prenatal diagnosis application of CMA technology. The compilation of the guideline for the application of CMA technology in prenatal diagnosis will strive to promote the standardization and advancement of prenatal diagnosis of fetal chromosome diseases in China.

- Abstract
Background: Rhizomelic limb shortening with dysmorphic features (RLSDF) has already been a disorder of the rare autosomal recessive skeletal dysplasia, just having a few reported cases. RLSDF is caused by protein kinase domain containing, cytoplasmic(PKDCC)gene variants. In this study, we describe the clinical features and potential RLSDF molecular etiology in a fetus from China., Methods: Genomic DNA (gDNA) extracted from the fetal muscle tissue and parents' peripheral blood was subjected to chromosomal microarray analysis (CMA) and trio-based whole exome sequencing (Trio-WES). The candidate pathogenic variants were verified by using Sanger sequencing., Results: Trio-WES identified two compound heterozygous variants in PKDCC, c.346delC (p.Pro117Argfs*113) and c.994G > T (p.Glu332Ter), inherited from the father and mother, respectively. Both variants are classified as pathogenic according to American College of Medical Genetics and Genomics guidelines., Conclusions: We reported the first prenatal case of RLSDF caused by PKDCC in the Chinese population. Our findings extended the variation spectrum of PKDCC and emphasized the necessity of WES for the early diagnosis of skeletal dysplasia and other ultrasound structural abnormalities in fetuses., (© 2023.

- Abstract
Objective: To summarize the clinical efficacy and nursing experience of intrauterine blood transfusion (IUT) treatment for fetal anemia cases., Methods: The clinical data of 4 fetal anemia cases receiving IUT in Beijing Obstetrics and Gynecology Hospital, Capital Medical University between 2020 and 2022 were collected. Four pregnant women aged 24-38 years were included in the study. They carried fetuses with anemia of unknown causes. The four pregnant women developed anxiety after they were informed of the diagnosis of fetal anemia. One-on-one psychological counseling before the IUT procedure and one-on-one companionship over the course of the surgery were provided for the pregnant women. In addition, they were closely monitored for blood transfusion reactions. Postprocedural observation of the puncture site and 24-hour monitoring of the newborns were also conducted., Results: The four pregnant women underwent 1-3 times of IUT in the second and third trimesters, with the minimum gestational age at the time of IUT being 25
+ weeks and the blood transfusion volume being 20-107 mL/time. Two pregnant women experienced irregular uterine contractions during IUT in the third trimester. Other than that, all other IUT treatments were successful. After IUT, there was a significant improvement in fetal hemoglobin, peak systolic velocity of the middle cerebral artery (MCA-PSV), and cardiothoracic area ratio. One case did not give birth in our hospital and the outcome of the fetus was not known. The other three fetuses achieved good outcomes., Conclusion: Positive preprocedural psychological counseling for pregnant women, close intraoprocedural and postprocedural pregnancy monitoring, and the prevention of maternal and fetal complications are the key to improving the clinical efficacy of IUT and achieving a good fetal outcome., (Copyright© by Editorial Board of Journal of Sichuan University (Medical Sciences).)- Published

- Abstract
Background: Rapid delivery is important in cases of umbilical cord prolapse to prevent hypoxic injury to the fetus/neonate. However, the optimal decision-to-delivery interval remains controversial., Objective: The aim of the study was to investigate the association between the decision-to-delivery interval in women with umbilical cord prolapse, stratified by fetal heart rate pattern at diagnosis, and neonatal outcome., Study Design: The database of a tertiary medical center was retrospectively searched for all cases of intrapartum cord prolapse between 2008 and 2021. The cohort was divided into three groups according to findings on the fetal heart tracing at diagnosis: 1) bradycardia; 2) decelerations without bradycardia; and 3) reassuring heart rate. The primary outcome measure was fetal acidosis. The correlation between cord blood indices and decision-to-delivery interval was analyzed using Spearman's rank correlation coefficient., Results: Of the total 103,917 deliveries performed during the study period, 130 (0.13%) were complicated by intrapartum umbilical cord prolapse. Division by fetal heart tracing yielded 22 women (16.92%) in group 1, 41 (31.53%) in group 2, and 67 (51.53%) in group 3. The median decision-to-delivery interval was 11.0 min (IQR 9.0-15.0); the interval was more than 20 min in 4 cases. The median cord arterial blood pH was 7.28 (IQR 7.24-7.32); pH was less than 7.2 in 4 neonates. There was no correlation of cord arterial pH with decision-to-delivery interval (Spearman's Ρ = - 0.113; Ρ = 0.368) or with fetal heart rate pattern (Spearman's Ρ = .425; Ρ = .079, Ρ = - .205; Ρ = .336, Ρ = - .324; Ρ = .122 for groups 1-3, respectively)., Conclusion: Intrapartum umbilical cord prolapse is a relatively rare obstetric emergency with an overall favorable neonatal outcome if managed in a timely manner, regardless of the immediately preceding fetal heart rate. In a clinical setting which includes a high obstetric volume and a rapid, protocol-based, response, there is apparently no significant correlation between decision-to-delivery interval and cord arterial cord pH., (© 2023.

- Abstract
Cytomegalovirus (CMV) is the most common cause of congenital infections in developed countries because is capable of infecting the fetus after both primary and recurrent maternal infection, and because the virus may be spread for years through infected children. Moreover, CMV is the most serious congenital infection associated with severe neurological and sensorineural sequelae, which can occur at birth or develop later on. Hygienic measures can prevent CMV transmission, which mainly involve contact with children under 3 years of age and attending a nursery or daycare. In animal and human pregnancies, many observational and controlled studies have shown that CMV-specific hyperimmune globulin (HIG) is safe and can significantly decrease maternal-fetal transmission of CMV infection and, mostly, the occurrence of CMV disease. Recently, valaciclovir at the dosage of 8 g/day was also reported to be capable of decreasing the rates of congenital infection and disease. However, comparing the results of our two recent case series, the infants born to women treated with HIG showed significantly lower rates of CMV DNA positivity in urine (9.7% vs. 75.0%; p < 0.0001) and abnormalities after follow-up (0.0% vs. 41.7%; p < 0.0001). The implementation of CMV screening would enable primary prevention via hygiene counseling, improve the understanding and awareness of congenital CMV infection, and increase the knowledge of the potential efficacy of preventive or therapeutic HIG or antiviral administration.

- Abstract
Objective: To evaluate the short- and long-term outcome of fetuses with evidence of extension of the choroid plexus into the frontal horns., Methods: This is a retrospective cohort study of fetuses diagnosed with isolated choroid plexi extending into the frontal horns. Fetuses with major central nervous system anomalies were excluded. Ultrasound and fetal/postnatal magnetic resonance imaging (MRI) were evaluated. Postnatal outcomes, including developmental assessment, were obtained., Results: Twenty nine fetuses were diagnosed with choroid plexus extension (22 unilateral and 7 bilateral). Gestational age at diagnosis was 19.3 weeks. Three cases (10.3%) presented with nonspecific extra-CNS findings. At presentation, 8/29 (28%) cases had single/multiple choroid plexus cysts (CPC). Twenty-six (89.6%) cases underwent antenatal MRI. On MRI, four cases had punctate susceptibility weighted imaging (SWI) foci suggesting trace hemosiderin and two cases had ventriculomegaly. Antenatal follow-up demonstrated resolution of the choroid plexus extension in 90% (18/20). Gestational age at delivery was 39.6 weeks. All had normal neurologic examinations within 24 h of life. Postnatal MRI studies were notable for deep venous differences in seven cases. Long-term clinical outcome was assessed in 14 cases with a median follow-up of 1.75 years, with normal neurodevelopment reported in 13/14 (92.8%)., Conclusions: Most fetuses with an anterior extension of the choroid plexus as the sole sonographic finding had favorable outcomes., (© 2023 John Wiley & Sons Ltd.)

- Abstract
Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a common cause of severe thrombocytopenia in newborns. Intracranial bleeding may lead to severe neurological sequelae and mortality. Current management of pregnancies at risk is suboptimal. Prenatal FNAIT diagnosis commonly requires invasive procedures and therapy is associated with a high treatment burden. The present review explores advances in the field and their potential contribution to modification of the diagnostic and therapeutic landscape. Topics addressed include the role of noninvasive prenatal testing using fetal cell free DNA, insights into novel and prospective therapeutic options achieved through the development of murine models of FNAIT as well as the forecast for the progress in pregnancy risk stratification through advancement in the investigation of biological characteristics of alloantibodies and their association with the risk of fetal bleeding., Competing Interests: None declared., (Thieme.

- Abstract
Background: Congenital cytomegalovirus (cCMV) is the most common congenital infection worldwide. cCMV can lead to severe long-term sequelae, including neurological impairment and developmental delay. We performed a systematic review of clinical practice guidelines containing recommendations concerning serological screening for CMV during pregnancy., Method: We performed a search of MEDLINE, Turning Research into Practice (TRIP) database and the grey literature for clinical practice guidelines or consensus statements published in the English language from Jan 2010 to June 2022. The quality of the included guidelines was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. Textual synthesis was used to summarise and compare the recommendations on CMV serological screening in pregnancy., Results: Eleven guidelines and two consensus statements were included. None recommended universal serological screening for CMV in pregnant women; five recommended screening for high-risk women (those with frequent contact with young children). The overall quality of the guidelines varied; most were medium or low., Conclusions: Although clinical practice guidelines do not actively recommend routine serological screening in pregnancy, most did not meet standard processes for development and predated the emerging data on valaciclovir as a potential intervention. Existing recommendations are underpinned by limited, low-level evidence, exposing the lack of robust data in this area of practice. Further high-level evidence and methodologically robust guidelines are needed to guide clinical practice in this rapidly changing field., (© 2023 The Authors.

- Abstract
Objective: To analysis the clinical characteristics of 400 fetuses with heart defects and the impactors of pregnancy decision making, and explore the influence of a multi-disciplinary team (MDT) cooperation approach on it. Methods: Clinical data of 400 fetuses with abnormal cardiac structure diagnosed at Peking University First Hospital from January 2012 to June 2021 were collected, which were divided into 4 groups according to the characteristics of fetal heart defects and the presence of extracardiac abnormalities or not: single cardiac defects without extracardiac abnormalities (122 cases), multiple cardiac defects without extracardiac abnormalities (100 cases), single cardiac defects with extracardiac abnormalities (115 cases), and multiple cardiac defects with extracardiac abnormalities (63 cases). The types of fetal cardiac structural abnormalities and genetic test results, and the detection rate of pathogenic genetic abnormalities, MDT consultation and management situation, and pregnancy decision of fetuses in each group were retrospectively analyzed. A logistics regression was used to analyze the influencing factors of fetal heart defects pregnancy decision. Results: (1) Among the 400 fetal heart defects, the four most common major types were ventricular septal defect 96 (24.0%, 96/400), tetralogy of Fallot 52 (13.0%, 52/400), coarctation of the aorta 34 (8.5%, 34/400), and atrioventricular septal defect 26 (6.5%, 26/400). (2) Among the 204 fetuses undergoing genetic examination, 44 (21.6%, 44/204) pathogenic genetic abnormalities were detected. (3) Detection rate of pathogenic genetic abnormalities (39.3%, 24/61) and pregnancy termination rate (86.1%, 99/115) in the single cardiac defects with extracardiac abnormalities group were significantly higher than those in the single cardiac defects without extracardiac abnormalities group [15.1% (8/53), 44.3% (54/122), respectively] and the multiple cardiac defects without extracardiac abnormalities group [6.1% (3/49), 70.0% (70/100), respectively, both P< 0.05], and the pregnancy termination rate in the multiple cardiac defects without extracardiac abnormalities group and the multiple cardiac defects with extracardiac abnormalities group (82.5%,52/63) were significantly higher than that of the single cardiac abnormalities without extracardiac abnormalities group (both P <0.05). (4) After adjusting for age, gravity, parity and performed prenatal diagnosis, maternal age, the diagnosis of gestational age, prognosis grades, co-existence of extracardiac abnormalities, presence of pathogenic genetic abnormalities, and receiving MDT consultation and management were still independent influencing factors of termination of pregnancy of fetuses with cardiac defects (all P <0.05). A total of 29 (7.2%, 29/400) fetal cardiac defects received MDT consultation and management, and compared with those without MDT management, the pregnancy termination rate in the multiple cardiac defects without extracardiac abnormalities group [74.2%(66/89) vs 4/11] and the multiple cardiac defects with extracardiac abnormalities group [87.9%(51/58) vs 1/5] were lower, the differences were statistically significant respectively (all P <0.05). Conclusions: Maternal age, diagnosed gestational age, severity of cardiac defects, extracardiac abnormalities, pathogenic genetic abnormalities and MDT counseling and management are the influencing factors of fetal heart defects pregnancy decision. MDT cooperation approach influences pregnancy decision-making and should be recommended for the management of fetal cardiac defect to reduce unnecessary termination of pregnancy and improve pregnancy outcomes.

- Abstract
Objective: We conducted a multicenter study to assess treatments and outcomes in a national cohort of infants with congenital ovarian cysts., Summary Background Data: Wide variability exists in the treatment of congenital ovarian cysts. The effects of various treatment strategies on outcomes, specifically ovarian preservation, are not known., Methods: Female infants diagnosed with congenital intra-abdominal cysts between 2013 and 2017 at 10 Canadian pediatric surgical centers were retrospectively evaluated. Sonographic characteristics, median time to cyst resolution, incidence of ovarian preservation, and predictors of surgery were evaluated. Subgroup analyses were performed in patients with complex cysts and cysts ≥40 mm in diameter., Results: The study population included 189 neonates. Median gestational age at diagnosis and median maximal prenatal cyst diameter were 33 weeks and 40 mm, respectively. Cysts resolved spontaneously in 117 patients (62%), 14 (7%) prenatally, and the remainder at a median age of 124 days. Intervention occurred in 61 patients (32%), including prenatal aspiration (2, 3%), ovary sparing resection (14, 23%), or oophorectomy (45, 74%). Surgery occurred at a median age of 7.4weeks. Independent predictors of surgery included postnatal cyst diameter ≥40 mm [odds ratio (OR) 6.19, 95% confidence interval (CI) 1.66-35.9] and sonographic complex cyst character (OR 63.6, 95% CI 10.9-1232). There was no significant difference in the odds of ovarian preservation (OR 3.06, 95% CI 0.86 -13.2) between patients who underwent early surgery (n = 22) and those initially observed for at least 3 months (n = 131)., Conclusions: Most congenital ovarian cysts are asymptomatic and spontaneously resolve. Early surgical intervention does not increase ovarian preservation., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 The Author(s).

- Abstract
Objective: Fetal arrhythmias are common and in rare cases can be associated with severe mortality and morbidity. Most existing articles are focused on classification of fetal arrhythmias in referral centers. Our main objective was to analyze types, clinical characteristics, and outcomes for arrhythmia cases in general practice., Case Report: We retrospectively reviewed a case series of fetal arrhythmias in a fetal medicine clinic between September 2017 and August 2021., Fetal Arrhythmias in Our Sample Presented by: Ectopies (86%, n = 57), bradyarrhythmias (11%, n = 7), and tachyarrhythmias (3%, n = 2). One tachyarrhythmia case was associated with Ebstein's anomaly. Two cases of second-degree AV block received transplacental fluorinated steroid therapy with recovery of fetal cardiac rhythm in later gestation. One case of complete AV block developed hydrops fetalis., Conclusion: Detection and careful stratification of fetal arrhythmias in obstetric screening is crucial. While most arrhythmias are benign and self-limited, some require prompt referral and timely intervention., Competing Interests: Declaration of competing interest Authors declare no actual or potential conflicts of interest., (Copyright © 2023.

- Abstract
Prenatal diagnosis of congenital heart disease makes it possible to optimize and coordinate care of the fetus and pregnant person. Benefits encompass the full spectrum of pre- and perinatal care, from counseling to optimization of pregnancy care and fetal intervention. Prenatal diagnosis reduces the likelihood of postnatal hemodynamic compromise and improves long-term neurodevelopmental outcomes. Despite the benefits, prenatal diagnosis rates remain suboptimal, particularly for lesions that are not seen on standard 4-chamber imaging views. Improving prenatal diagnosis rates requires education and outreach efforts targeting community practices where most initial screening occurs., (Copyright © 2023 by the American Academy of Pediatrics.)

- Abstract
Establishing the diagnosis of a fetal genetic disease in utero expands decision-making opportunities for individuals during pregnancy and enables providers to tailor prenatal care and surveillance to disease-specific risks. The selection of prenatal genetic tests is guided by key details from fetal imaging, family and obstetrical history, suspected diagnoses and mechanisms of disease, an accurate understanding of what abnormalities each test is designed to detect, and, at times, the gestational age at which testing is initiated. Pre- and posttest counseling, by or in conjunction with providers trained in genetics, ensure an accurate understanding of genetic tests, their potential results and limitations, estimated turnaround time for results, and the clinical implications of their findings. As prenatal diagnosis and testing options continue to expand rapidly, it is increasingly important for obstetrical providers to understand how to choose appropriate genetic testing and contextualize the clinical implications of their results., (Copyright © 2022 Elsevier Inc.

- Abstract
Introduction: Neonates with cardiorespiratory compromise at delivery are at substantial risk of hypoxic neurologic injury and death. Though mitigation strategies such as ex-utero intrapartum treatment (EXIT) exist, the competing interests of neonatal beneficence, maternal non-maleficence, and just distribution of resources require consideration. Due to the rarity of these entities, there are few systematic data to guide evidence-based standards. This multi-institutional, interdisciplinary approach aims to elucidate the current scope of diagnoses that might be considered for such treatments and examine if treatment allocation and/or outcomes could be improved., Methods: After IRB approval, a survey investigating diagnoses appropriate for EXIT consultation and procedure, variables within each diagnosis, occurrence of maternal and neonatal adverse outcomes, and instances of suboptimal resource allocation in the last decade was sent to all North American Fetal Treatment Network center representatives. One response was recorded per center., Results: We received a 91% response rate and all but one center offer EXIT. Most centers (34/40, 85%) performed 1-5 EXIT consultations per year and 17/40 (42.5%) centers performed 1-5 EXIT procedures in the last 10 years. The diagnoses with the highest degree of agreement between centers surveyed to justify consultation for EXIT are head and neck mass (100%), congenital high airway obstruction (90%), and craniofacial skeletal conditions (82.5%). Maternal adverse outcomes were noted in 7.5% of centers while neonatal adverse outcomes in 27.5%. A large percentage of centers report cases of suboptimal selection for risk mitigation procedures and several centers experienced adverse neonatal and maternal outcomes., Conclusion: This study captures the scope of EXIT indications and is the first to demonstrate the mismatch in resource allocation for this population. Further, it reports on attributable adverse outcomes. Given suboptimal allocation and adverse outcomes, further examination of indications, outcomes, and resource use is justified to drive evidence-based protocols., (© 2023 S. Karger AG, Basel.)

- Abstract
Objectives: Although many studies have supported the efficacy of transplacental treatment for fetal supraventricular tachyarrhythmia, the long-term neurodevelopmental outcome after antenatal antiarrhythmic treatment is not well understood. The aim of this study was to investigate the prognosis and neurodevelopmental outcome at 36 months of corrected age and the incidence of tachyarrhythmia after birth, following protocol-defined antenatal therapy for fetal supraventricular tachyarrhythmia., Methods: This was a 3-year follow-up study of a multicenter trial that evaluated the efficacy and safety of protocol-defined transplacental treatment for fetal supraventricular tachycardia (SVT) and atrial flutter (AFL). The primary endpoints were mortality and neurodevelopmental impairment (NDI) at 36 months of corrected age. NDI was defined as any of the following outcomes: cerebral palsy, bilateral blindness, bilateral deafness or neurodevelopmental delay. Neurodevelopmental delay was evaluated using appropriate developmental quotient scales, mainly the Kyoto Scale of Psychological Development, or examination by pediatric neurologists. The detection rate of tachyarrhythmia at birth and at 18 and 36 months of corrected age was also evaluated as the secondary endpoint. In addition, the association of NDI at 36 months with perinatal and postnatal factors was analyzed., Results: Of 50 patients enrolled in the original trial, one withdrew consent and in two there was fetal death, leaving 47 patients available for enrollment in this follow-up study. Of these, 45 cases were available for analysis after two infants were lost to follow-up. The mortality rate was 2.2% (1/45) during a median follow-up of 3.2 (range, 2.1-9.4) years. The infant died at the age of 2.1 years. Another infant had missing neurodevelopmental assessment data. In the remaining 43 infants, at 36 months of corrected age, NDI was detected in 9.3% (4/43) overall and in two of three (66.7%) cases with fetal hydrops with subcutaneous edema. Cerebral palsy was noted in two infants with severe subcutaneous edema or ascites at an early gestational age. Neurodevelopmental delay was found in two infants with severe congenital abnormalities (one with tuberous sclerosis and the other with heterotaxy syndrome). Tachyarrhythmia was present in 31.9% (15/47) cases in the neonatal period and decreased to 8.9% (4/45) and 4.5% (2/44) at 18 and 36 months of corrected age, respectively. The median ventricular rate at diagnosis was significantly higher in infants with NDI compared to those without (265 vs 229 bpm; P = 0.003). In infants with NDI, compared to those without, fetal hydrops with subcutaneous edema at diagnosis was more common (50.0% vs 2.6%; P = 0.019) and the duration of fetal effusion was longer (median, 10.5 vs 0 days; P = 0.013). Postnatal arrhythmia and physical development abnormalities were not associated with NDI., Conclusions: This multicenter 3-year follow-up study is the first to demonstrate the long-term mortality and morbidity of infants born following protocol-defined transplacental treatment for fetal SVT and AFL. NDI was associated with the presence of fetal hydrops with subcutaneous edema at diagnosis and longer duration of fetal effusion. Neurodevelopmental delay was detected only in infants with severe congenital abnormalities. Therefore, in infants that have undergone antenatal treatment for fetal tachyarrhythmia and in which there are no comorbidities, the risk of NDI is low. However, in those with fetal hydrops with subcutaneous edema and/or associated severe congenital abnormalities, the risk for long-term neurologic morbidity might be considered somewhat increased. © 2022 International Society of Ultrasound in Obstetrics and Gynecology., (© 2022 International Society of Ultrasound in Obstetrics and Gynecology.)

- Abstract
Introduction: Isolated lateral ventricular asymmetry has been associated with a favorable prognosis; however, prenatal evaluations in existing studies have been conducted using ultrasonography (US). This study aimed to describe the magnetic resonance imaging (MRI) findings, progression of ventricular asymmetry, and perinatal outcomes in fetuses prenatally diagnosed with isolated ventricular asymmetry., Methods: This retrospective study included patients who underwent MRI for isolated fetal ventricular asymmetry at a tertiary center between January 2012 and January 2020. Information, including pregnancy history, US, MRI findings, and perinatal outcomes, was obtained from medical records., Results: The study cohort included 17 women with fetal ventricular asymmetry but without ventriculomegaly at the time of index US. Mild ventriculomegaly subsequently developed in 13 patients; 12 of them showed spontaneous resolution before delivery. MRI identified low-grade intraventricular hemorrhage (IVH) in 13 fetuses. Postnatally, 12 newborns underwent neonatal cranial US where two of them showed evidence of germinal matrix hemorrhage. Both newborns appeared normal at birth without neonatal complications., Conclusion: MRI identified low-grade IVH in most fetuses with isolated ventricular asymmetry. These fetuses were also likely to develop mild ventriculomegaly with spontaneous resolution. Although perinatal outcomes appeared good, careful follow-up in both prenatal and postnatal periods is warranted., (© 2023 The Author(s). Published by S. Karger AG, Basel.)
