Prenatal Cardiac Ultrasound Markers of Outcomes in Ebstein's Anomaly: An International Multicenter Case Series.

This study aimed to analyze prenatal cardiac ultrasound markers of outcome in fetuses with Ebstein's anomaly (EA). From a retrospective database, 35 fetuses diagnosed with EA at fetal medicine centers in Brazil, Italy, and Poland were retrieved. The primary outcome was perinatal mortality. We analyzed prenatal cardiac ultrasound markers of outcomes and perinatal follow-up. Gestational age at diagnosis, extracardiac fetal anomalies, spontaneous fetal demise, and gestational age at each event were recorded. In postnatal survivors, data on cardiac surgery and short-term postoperative outcomes were collected. Our study included a cohort of 35 fetuses with EA (mean gestational age of 29.4 weeks), in which 6 fetuses were excluded due to termination of pregnancy (3), pregnancy still ongoing (2), and missed follow-up (1). Of the remaining 29 cases, severe tricuspid regurgitation and absence of anterograde pulmonary flow (pulmonary atresia) were observed in 88%. Significant cardiomegaly accounts for 58% of these data with a mean cardiothoracic ratio of 0.59. The cardiovascular profile (CVS) score ≤ 6 in six patients with one survival (4 fetal deaths, one stillbirth, and one survival). All fetuses with CVS score of 5 had intrauterine demise. Seventeen fetuses were born alive (53.1% of 29 cases). Of the remaining fetuses, one (1%) fetal was a stillbirth, six (20%) fetuses were neonatal deaths, and five (17%) fetuses were fetal deaths. Of the nineteen patients who underwent surgery to correct the cardiac defect, 17 survived after surgery. Among the survivors, biventricular cardiac repair was performed using the cone technique (da Silva's approach) in the majority of cases. We observed 2 abnormal karyotypes among in the remaining 29 fetuses. One of the patients with abnormal karyotype was a fetus with ascites and large for gestational age. The other patient with abnormal karyotype underwent cardiac surgery and progressed to neonatal death. Nine patients (25%) had extracardiac anomalies (genitourinary anomalies and single umbilical artery), being that 2 of them are alive and 4 died (2 had fetal and 2 neonatal death). Fetal EA is associated with high mortality. The most common prenatal marker associated with non-survival was CVP score ≤ 6. Fetuses that survived and underwent postnatal corrective surgery are significantly favorable outcomes.

Placental thickness in 2D prenatal ultrasonographic examination.

Introduction: The placental thickness (PTh) is an ultrasonographic measurement commonly used to assess the placenta. The study aimed to determine selected factors influencing PTh in 2D prenatal ultrasonographic examination. It might have a special value in difficult cases for interpretation when PTh is above or below the reference values. Material and methods: In this retrospective study, we analysed the results of foetal ECHO examination of 2833 foetuses performed between June 2016 and December 2019 in our single unit. 596 healthy foetuses older than 12 weeks of gestation from singleton pregnancies were enrolled in the study. The following parameters were used in the further analysis: placental implantation site, gestational age according to the last menstrual period (LMP) and foetal biometry (FB); maternal weight, height, and body mass index (BMI) at the time of examination; and PTh. Results: PTh was affected by its location: posterior 33 mm vs. anterior 30 mm (p < 0.001). Moreover, its thickness significantly correlated with gestational age according to FB (r = 0.386, p < 0.001), LMP (r = 0.369, p < 0.001), maternal weight (r = 0.192, p < 0.001), height (r = 0.125, p = 0.002), and BMI (r = 0.147, p < 0.001), but not with maternal age (r = 0.050, p = 0.219). A linear regression model based on these data explained the 16.38% variability of the tested subjects (p < 0.001). Conclusions: Our observations suggest that maternal weight correlated more strongly with PTh than maternal BMI. For PTh evaluation, it is important to pay attention to the placental implantation site - the posterior placenta was thicker than the anterior placenta. Moreover, PTh variability remains largely unknown; therefore, further research in this field is needed.

Prenatal Echo-Sonographic Parameters in Fetuses Wrapped with the Umbilical Cord in the Third Trimester of Pregnancy.

This study constitutes a description of prenatal echo-sonographic parameters in fetuses wrapped with the umbilical cord in the third trimester of pregnancy and demonstrates the practical importance of the umbilical cord collision. Echocardiographic examinations were performed within 6 months, and a group of patients in the third trimester with a mean age of 28.1 ± 0.79 weeks of gestation (p = 0.075) was distinguished. The group included 46 fetuses from single pregnancies with the umbilical cord around the fetal neck and 70 fetuses without the umbilical cord around the fetal neck. The course of the umbilical cord coiling around the fetal neck was recorded by color Doppler. We also conducted a follow-up with the newborns. In the study group, there was an elevated peak systolic velocity of the umbilical artery (UMB PSV) at a level of 44.17 cm/s vs. 38.90 cm/s in the control group (p = 0.004), and caesarean sections were significantly more frequent (54.5% vs. 31.4%). The persistence of the nuchal cord during delivery was observed in 37% of newborns in the study group, while the occurrence of umbilical wrapping during delivery was found in 18.6% of newborns in the control group (p = 0.027). In the studied cases, caesarean sections were 2.62 times more frequent (OR = 2.62), whereas nuchal cords during delivery were 2.57 times more often observed (OR = 2.57). Fetal umbilical cord wrapping in the third trimester of pregnancy does not have a significant hemodynamic impact; however, the UMB PSV might be slightly elevated in this group, and the frequency of umbilical cord collision during delivery and the need to perform a caesarean section at term seem to be more common.

Fetal Third-Trimester Functional Cardiovascular Abnormalities and Neonatal Elevated Bilirubin Level.

BACKGROUND: The aim of the study was to analyze the neonatal outcomes of fetuses with diagnosed functional cardiovascular abnormalities, also considering the connection with neonatal hyperbilirubinemia. MATERIALS AND METHODS: It was an observational study of 100 neonates who had fetal echocardiography examinations in the third trimester (mean gestational age during the last echocardiography was 34 ± 3 weeks and mean birth weight was 3550 g). There were two groups: A: normal heart anatomy + no functional anomalies; group B: normal heart anatomy + functional abnormalities. Hyperbilirubinemia was defined as a bilirubin level of >10 mg%. RESULTS: In group A, there were 72 cases and only 5 cases despite having normal heart anatomy and normal heart study that presented additional problems. In group B (28 cases), the prenatal functional findings included tricuspid regurgitation (TR) (15 cases, 53%), pericardial effusion (4 cases, 14%), myocardial hypertrophy (4 cases, 14%), cardiomegaly (2 cases, 7%), abnormal bidirectional blood flow across the foramen ovale (3 cases, 11%), aneurysm of atrial septum (2 case, 7%), abnormal E/A ratio for mitral and tricuspid valve (1 case, 3%), bright spot (3 case, 11%), abnormal Doppler flow in ductus arteriosus compared to aortic arch (difference >60 cm/s) (1 case, 3%), supraventricular tachycardia (SVT) (1 case), and mitral regurgitation (1 case, 3%). In group A (n = 72 cases), bilirubin levels of >10 mg/dL were observed in 8% of newborns. In group B (n = 28), bilirubin levels of > 10 m/dL were observed in 46% of cases and TR was present in group B in 53% of cases (15/28 cases). The difference between group A and B in terms of elevated bilirubin levels was statistically significant (p < 0.001). CONCLUSIONS: In the case of fetal normal heart anatomy and normal heart study, a good neonatal outcome may be expected. When fetal cardiovascular functional abnormalities in normal heart anatomy are detected, with special attention paid to tricuspid valve regurgitation, a neonatal elevated bilirubin level (mean 11 mg/dL, range 10-15 mg/dL) may be expected.

Fetal Cardiac Hemodynamic and Sonographic Anomalies in Maternal COVID-19 Infection Depending on Vaccination Status-Polish Multicenter Cohort Study.

Most obstetrical studies have focused on maternal response to the SARS-CoV-2 virus but much less is known about the effect of COVID-19 on fetal physiology. We aimed to evaluate the effect of the maternal SARS-CoV-2 infection on the fetal homeostasis with the use of detailed ultrasonography and echocardiography and consideration of the effect of vaccination. This was a multi-center study of fetuses who had prenatal detailed ultrasound and echocardiographic examinations performed by fetal cardiology specialists. The subjects were divided based on the COVID vaccination status (vaccinated women who did not have COVID-group V, unvaccinated women who had COVID-group UV, and unvaccinated women who did not have COVID-control group). We evaluated the ultrasound and echocardiography results obtained. The study group included 237 gravidas from four prenatal cardiology centers. In the group of fetuses with normal heart anatomy, normal cardiovascular function had 147 (81%) fetuses and functional cardiovascular anomalies were present in 35 (19%) cases. Functional cardiovascular anomalies were present in 11 (16%) fetuses in the V group, 19 (47%) fetuses in the UV group and 5 (8%) fetuses in the control group (p < 0.01). There were 56 (24%) fetuses with extracardiac anomalies. Extracardiac anomalies were present in 20 (22%) fetuses in the V group, 22 (45%) fetuses of the UV group and in 14 (14%) fetuses in the control group (p < 0.01). Our study has proved that maternal COVID-19 infection can affect the fetal physiology and mild cardiac and extracardiac markers detected by fetal ultrasonography and echocardiography. Moreover, maternal vaccination results in lower occurrence of these findings in fetuses.

Small prenatal diameter of the ascending aorta is associated with increased mortality risk in neonates with congenital diaphragmatic hernia.

Introduction: The aim of this study was to evaluate whether selected prenatal markers obtained from fetal echocardiography can predict postnatal outcome in congenital diaphragmatic hernia (CDH) patients. We also aimed to verify the prognostic value of lung-to-head ratio (LHR). Material and methods: The study group included 29 fetuses with CDH. We analyzed potentially prognostic parameters measured using fetal echocardiography and fetal ultrasound. The assessed parameters were compared between the group of patients with CDH who survived to discharge (n = 21) and the subset of patients who died before discharge from hospital (n = 8). Results: In survivors, mean z-score for ascending aorta (AAo) diameter was 0.23 ±0.98 vs. - 1.82 ±1.04 in patients who died (t-test, p = 0.0015). In survivors, the main pulmonary artery/ascending aorta ratio was 1.22 ±0.17 vs. 1.46 ±0.21 in patients who died (t-test, p = 0.017). In survivors, the LHR was 1.81 ±0.96 vs. 0.95 ±0.6 in patients who died (t-test, p = 0.019). In survivors, the observed to expected LHR was 57 ±30% vs 30 ±18% in patients who died (t-test, p = 0.018). Conclusions: Narrowing of the ascending aorta in CDH fetuses is a poor prognostic factor associated with increased mortality in neonates. Our study also confirmed the prognostic value of LHR.

Measurement of the Fetal Ear Length Has No Clinical Value.

The long-term monitoring of a fetus with genetic and non-genetic anomalies is still a challenge for prenatal medicine. Ultrasound screening must be based on some measurement ranges, which show the trend of development of fetal body parts in a given period of time. One of them is the fetal ear auricle. This study presents an analysis of the fetal ear auricle length in healthy fetuses to establish normal ranges of fetal ear auricle length. The study group included 132 healthy fetuses. The gestational age of healthy fetuses ranged from 17.0 to 39.5 weeks of gestation according to LMP. The range of fetal ear length measurement was 10.00-40.00 mm with an average value of 23.49 mm. In the group of fetuses in the second trimester of pregnancy, the range of fetal ear length measurement was 18.00-28.00 mm, whereas in the group of fetuses in the third trimester of pregnancy, the range was 16.00-40.00 mm. In order to check the usefulness of this parameter, an analysis of this marker in fetuses with extracardiac anomalies, including genetic and non-genetic disorders is shown. The fetal ear measurement can fall within the normal range even if there are some genetic or non-genetic disorders. Therefore, the fetal ear measurement does not provide any diagnostic value in terms of detecting any fetal genetic and non-genetic disorders, which is supported by the analysis of the data provided in this study. Our study has proved that measurement of the fetal ear auricle is possible; however, its clinical usefulness for perinatal management is currently very limited.

Ectopia cordis: prenatal diagnosis, perinatal outcomes, and postnatal follow-up of an international multicenter cohort case series.

OBJECTIVE: This study aimed to analyze prenatal diagnosis, perinatal outcomes, and postnatal follow-up in fetuses with ectopia cordis (EC). METHODS: This retrospective analysis accessed 31 patients with EC who were either diagnosed or referred to a tertiary Fetal Medicine centers for EC diagnosis in Brazil, Germany, Italy, and Poland. We analyzed prenatal diagnosis, perinatal outcomes, and follow-up in these patients. RESULTS: Our study included a cohort of 31 fetuses with EC, 4 and 27 of whom had partial and complete protrusion of the heart through a ventral defect in the thoracoabdominal wall, respectively. EC was diagnosed by fetal echocardiography at a mean gestational age of 20.3 ± 8.6 weeks (range, 8-35 weeks). Of the four cases, in which the karyotype was performed, all of them had a normal result (1 - 46,XX and 3 - 46,XY). Five patients showed conotruncal abnormalities and six ventricular septal defects. Termination of pregnancy (TOP) was performed in 15 cases (48%) and seven pregnant women had spontaneous fetal demise (22.5%). Of the seven fetuses that were born alive, four of them died, and three infants underwent surgery. Among these three infants, all of them survived, one was 5 months, 13 years old and 29 years old at the time of study completion. CONCLUSIONS: Ectopia cordis is associated with high mortality rates and intracardiac/extra-cardiac defects. Ventricular septal defects and conotruncal anomalies were the more common intracardiac defects associated with EC. However, in this cohort of fetuses with EC the incidence of PC was lower than reported in the literature.

The Presence of a Single Nuchal Cord in the Third Trimester May Not Affect Tei Index in LGA Fetuses.

(1) Background: The aim of this study was to assess the RV (right ventricle) and LV (left ventricle) Tei index in large for gestational age (LGA) fetuses with a single 360-degree umbilical coil of the umbilical cord around the fetal neck identified by ultrasound in the third trimester of gestation. (2) Methods: The RV and LV Tei index for the cardiac function were measured in 297 singleton pregnancies, and we identified 25 LGA fetuses. There were 48% of LGA fetuses with a nuchal umbilical cord-LGA/NC-larger for gestational age fetuses with a nuchal cord. NC was detected with a color Doppler during a transverse scan of the fetal neck, when the umbilical cord formed a U shape. All fetuses had normal anatomy and normal uterine, placental, umbilical, intracardiac and cerebral Doppler waveforms values for their gestational age. (3) Results: The RV Tei index was significantly higher in the LGA subgroup vs. AGA (0.6 ± 0.2 vs. 0.50 ± 0.2; p value = 0.01), but in LGA fetuses with a single coil of the nuchal cord, there were not any significant changes in the Tei indexes. (4) Conclusions: The Tei index might not be impacted by the presence of the nuchal cord in LGA fetuses.

Fetal heart biventricular diameter/foot length index as a diagnostic marker of fetal macrosomia in the second and third trimester of pregnancy.

PURPOSE: Fetal macrosomia may have serious effects on both mother and newborn, so it is important to correctly evaluate the fetal weight before delivery. Fetal routine biometry, height of the fundus of uterus, interventricular septal thickness seems to be very good but still not perfect. In our study the relation between fetal biventricular (AP) diameter and fetal foot length was elaborated in the 2nd and 3rd trimester of pregnancy. MATERIAL AND METHODS: The analyzed group (n = 423 fetuses) was divided into 2 subgroups: a control group (n = 109 fetuses) with normal biometry, normal heart anatomy and normal cardiac function, no extracardiac malformation, no extracardiac anomalies, gestational age ranged from 17.5 to 37.1 weeks of gestation, born at term with birth weight 3000-3600 g, and a study group (n = 314 fetuses) with gestational age 17.5-39.5 weeks. Among the study group there were 20 patients (n = 20 fetuses) with macrosomia defined as a neonatal birth weight of greater than or equal to 4000 g. The control group was used to generate normograms on fetal AP, foot length and AP/Foot Index. The Statistica 13.3 and Excel 365 software were used to calculate the sensitivity, specificity, positive predictive value and negative predictive values. RESULTS: In control group, the mean biventricular fetal heart (AP) measurement was 23 mm (12.9 mm-38 mm), the mean foot length was 43 mm (24 mm-71 mm), and the mean AP/Foot Index was 0.52 (0.40-0.65). The value of the AP/Foot Index in the second trimester of the control group was 0.53, whereas the AP/Foot Index in the third trimester of pregnancy was 0.51. The use of standard fetal biometry resulted in the prediction of macrosomia in 20%, whereas the AP/Foot index in addition to standard fetal biometry enabled the detection of 65% of macrosomia. CONCLUSIONS: The AP/Foot Index higher than 0.52 has greater sensitivity and negative predictive value to detect macrosomia compared to standard ultrasound fetal biometry.

Maternal hyperoxygenation during pregnancy as a tool in fetal disease diagnosis and treatment.

Maternal hyperoxygenation (MHO) consists of giving pregnant women (60% to 100%) oxygen through a facemask and using ultrasound assess or monitor the influence on fetal cardiovascular circulation. This review discusses the findings and the utility of acute and chronic MHO in various fetal diseases.

Functional assessment of atrial wall excursion and foramen ovale flap tracings in 3rd trimester as predictor of short-term hemodynamic stability in congenital heart defects fetuses.

OBJECTIVES: Right atrium and left atrium of the fetal heart play a fundamental role in fetal heart circulatory physiology. METHODS: Excursion of fetal atria walls and tracings of foramen ovale (FO) flap movement were analyzed by M-mode echocardiography by new FO index to determine fetal and neonatal outcome in the first week and month of life in various congenital heart defects. The study group was divided into 3 subgroups: group A: neonates stable after birth (all on I.V. prostaglandin infusion) for at least 7 days, group B: neonates unstable after birth (despite I.V. prostaglandin infusion) requiring catheterization procedure or early cardiac surgery <6th day of life and group C: fetuses with in utero demise. RESULTS: The average values of FO index: group A - 32, group B - 20, group C - 12.Schaffe test showed statistical difference of FO index between group A and B (p=0.029) and group A and C (p=0.001), but no difference between group B and C (p=0.24) The FO index of stability was determined by ROC curve analysis. Cut-off point distinguishing between postnatal stability and postnatal instability + in utero demise constituted FO index=25 (specificity 82%; sensitivity 90%). CONCLUSIONS: Prenatal features of atrial M-mode echocardiography shortly before birth might be helpful to predict the short term prognosis of fetal hemodynamic stability or instability shortly after birth regardless of the type of congenital heart defects (CHD).

Maternal urogenital infection and fetal heart functional assessment - what is the missing link?

OBJECTIVES: Maternal urogenital infections during pregnancy are worldwide frequent problem. The aim was to analyze influence of maternal genitourinary infection on fetal cardiac function, pregnancy development and obstetrical outcomes. METHODS: This was a single-center cohort study on fetuses (average at 28th week) in two groups: with maternal urogenital infections (study group n=49) and control group with no infections (n=59). Parvovirus B19, toxoplasmosis, cytomegalovirus, herpes simplex infections, congenital malformations, fetal growth restriction, chronic maternal diseases, as well as patients with body mass index (BMI) >25 kg/m2 were excluded. We analyzed: maternal age, time of delivery, neonatal birth weight, Apgar scores, average time of hospitalization of newborns after birth and several fetal echocardiographic parameters. RESULTS: The only statistical differences was found for shorter isovolumetric relaxation time (IRT) (40 ± 10 vs. 45 ± 9; p=0.03) and longer ejection time (ET) [ms] for right ventricle (RV) (176 ± 24 vs. 164 ± 18; p=0.01). Thick placenta was observed more frequent in study group than in controls (36.7 vs. 16.9%; p= 0.02). CONCLUSIONS: The missing link for explanation of these findings was coincidence with thick placenta. This is probably the first observation suggesting that thick placenta (>5 cm) may affect fetal RV function in normal heart anatomy: prolongation of right ventricular ET and shortening of fetal right ventricular IVRT.

Cardiac Adaptation and Preferential Streaming in Fetuses with Multiple Nuchal Cords.

The echocardiographic monitoring of a fetus with multiple nuchal cords around the fetal neck is important as it may result in cardiac remodeling and preferential streaming, thus affecting the condition of the fetus. The main aim of our study was to assess whether the collision of the umbilical cord around the fetal neck can lead to discrepancies in the size of the pulmonary artery and the aorta in the three-vessel view and to an increase in the size of the heart, which may result from the compression of the carotid arteries caused by the umbilical cord wrapping around the fetal neck. A total number of 854 patients were included in this study and divided into three groups. Group A (control group) included 716 fetuses (84%) without the umbilical cord around the fetal neck. Group B (study group B) included 102 fetuses (12%) with one coil of the umbilical cord around the fetal neck. Group C (study group C) included 32 fetuses (4%) with two coils of the umbilical cord around the fetal neck. The range of the gestational age of the patients considered for this study was 27-40.2 weeks based on the ultrasound biometry and was not statistically different between the analyzed groups A, B and C (p > 0.05). The Pa/Ao index was calculated by dividing the value of the width of the pulmonary artery (in mm) to the width of the aorta (in mm) measured in the ultrasound three-vessel view. We found that fetuses that the fetuses with one and two coils of the umbilical cord around the neck showed significantly higher values of the width of the pulmonary trunk with the unchanged value of the aorta width. Therefore, we also observed significantly higher values of the ratio of the pulmonary trunk to the aorta for the fetuses wrapped with the umbilical cord around the neck compared with the control group without the umbilical cord around the neck (. Moreover, in the fetuses with one and two coils of the umbilical cord around the fetal neck, an increased amount of amniotic fluid was observed, whereas larger dimensions of CTAR in the fetuses with two coils of the umbilical cord around the neck were present (p < 0.05). The wrapping of the fetus with the umbilical cord around the fetal neck may induce the redistribution of blood flow, leading to fetal heart enlargement and disproportion and may be the cause of polyhydramnios.

Normograms in Prenatal Life of Stomach and Urinary Bladder in the Second and Third Trimesters of Pregnancy.

Aim: The aim of this study was to prepare normograms for the fetal stomach, urinary bladder, and stomach to urinary bladder index in healthy fetuses. Material and methods: The study was conducted based on the data extracted from the database of our tertiary center in the years 2016-2019. The study group, comprising 867 fetuses, demonstrated normal biometry and normal heart structure, normal heart function, no extracardiac malformations, and no extracardiac anomalies. The stomach to urinary bladder index was analyzed in the study group. The examinations were performed with the use of the following ultrasound machines: Voluson E10, Philips and Voluson Expert, with convex transabdominal transducers. Linear regression analysis based on Microsoft Excel was used for statistical analysis. Results: The average size of the stomach in healthy fetuses between the 14-40th week of gestation was 18 mm (8-40 mm), the average urinary bladder measurement was 17 mm (15-42 mm), and the fetal stomach to urinary bladder index was constant: 1.26 (0.09-3.93). Conclusions: The normograms for the stomach, urinary bladder and the stomach to urinary bladder index prepared based on our study group can contribute to an improvement in the accuracy of examination and provide an unified organization of the description of fetuses. These normograms constitute an additional marker for the assessment of fetal condition. A clear disproportion in the size of the urinary bladder and stomach can be helpful in terms of paying more attention to fetuses with untypical features in screening centers.

Longitudinal Surveillance of Fetal Heart Failure Using Speckle Tracking Analysis.

Long-term monitoring of a fetus with heart failure is an undeniable challenge for prenatal cardiology. Echocardiography is constrained by many fetal and maternal factors, and it is difficult to maintain the reproducibility of the measured and analyzed parameters. In our study, we presented the possibilities of using modern speckle tracking technology in combination with standard echocardiography parameters that may be insufficient or less sensitive in the context of monitoring life-threatening fetal conditions. Our analysis shows the superiority of the parameters used to assess fetal cardiac architecture, such as the GSI Global sphericity Index, and fetal cardiac function, such as the FAC fractional area change and the EF ejection fraction, which temporal change may indicate a worsening condition of the fetus with heart failure. The significant increase in the parameters of fetal heart size in speckle tracking allows for an improved echocardiographic diagnosis and monitoring of the fetus with heart failure and the prognostic conclusions about the clinical condition after birth. Significant decreases in FAC for the left and right ventricles and EF for the left ventricle may indicate an unfavourable prognosis for the monitored fetus due to heart failure.

The Causes and Role of Antinatalism in Poland in the Context of Climate Change, Obstetric Care, and Mental Health.

Antinatalism is an umbrella term for numerous moral dilemmas associated with procreation. In the past few years, the deterioration of environmental conditions, social difficulties, global worsening of people's mental health, and pandemics have induced discussion about antinatalism. Therefore, we aimed to characterize antinatalists in the Polish population in terms of the frequency and description of the main reasons behind this phenomenon. The cross-sectional study was performed in the Polish population. An online, four-part survey was performed between 19 and 25 January 2022. The study group comprised 1240 respondents. Antinatalists (n = 472, 38%) were defined as people who do not have children and want to be childless in the future, whereas pronatalists (n = 768, 62%) consisted of people who want to have offspring in the future and/or already have children. The opinion that climate change is a significant reason not to have a child appeared twice as often among antinatalists. Additionally, the performed binary logistic regression model highlighted the importance of the fear of climate change as an independent factor facilitating an antinatalistic attitude. Regarding females, the following factors discouraging them from having a child were observed: fear of child's congenital diseases, pregnancy complications, dissatisfaction with medical services, and fear of exacerbation of maternal chronic diseases. Anxiety, depression, and stress were not found to be statistically different between pro- and antinatalist groups. However, further analysis revealed that female antinatalists were significantly more depressive and anxious. Our study helps us to understand why, as mentioned beforehand, around 38% of respondents prefer to stay childless. In conclusion, antinatalism views have become relatively prevalent in society, and its reasons include environmental antinatalism and medical factors, including depression and anxiety. However, better access to medical services and changes in climate politics were not found to be significant factors in encouraging society to decide to have offspring.

Fetal echocardiography and early neonatal balloon valvuloplasty improved overall survival in prenatally detected aortic stenosis over 25 years of tertiary center experience.

PURPOSE: This article aimed to present the factors determining survival and prognosis in fetuses and newborns with critical prenatal aortic stenosis (AS) and to present 26 years of tertiary center experience. METHODS: Study included 87 fetuses with critical AS requiring surgical intervention during neonatal period. All results were expressed as means ± SD, in numbers and percentages. The statistically significant results were those with p < 0.05. RESULTS: An increase in the number of cases of AS was observed in our center along with a decrease in gestational age of our patients during the first echocardiographic exam. The survival rate of newborns was considerably higher when born in due time (p < 0.05) with body weight > 2500 g (p < 0.05). Balloon valvuloplasty performed in the first days after birth occurred to be an optimal solution in these cases. CONCLUSIONS: Fetal echocardiography and special perinatal care with transplacental maternal pharmacotherapy in selected cases and an early neonatal aortic balloon valvuloplasty have shown improvement in survival rate. The most dangerous for the newborn with AS was the first week of postnatal life. It is vital to refer the fetuses with AS to the reference centers which offer the possibility of invasive cardiac intervention on the first day after birth, and it might be an optimal solution.

Longitudinal functional assessment of atrial M-mode in dextro- transposition of the great arteries fetus may help to predict the necessity for urgent neonatal Rashkind procedure.

Six fetal echocardiographic examinations were analyzed and presented with special emphasis on atrial M-mode in one case of fetal isolated dextro- transposition of the great arteries. The only significant changes were seen based on analysis of the new index of foramen ovale (FO) flap movement. Emergency Rashkind procedure on the first day of postnatal life was predicted based on fetal atrial M-mode.
