Association of European Paediatric and Congenital Cardiology practical recommendations for surveillance and prevention of cardiac disease in childhood cancer survivors: the importance of physical activity and lifestyle changes From the Association of European Paediatric and Congenital Cardiology Working Group Sports Cardiology, Physical Activity and Prevention, Working Group Adult Congenital Heart Disease, Working Group Imaging and Working Group Heart Failure.

BACKGROUND: Childhood cancer survivors are at increased risk of developing cardiovascular diseases, presenting as the main causes of morbidity and mortality within this group. Besides the usual primary and secondary prevention in combination with screening during follow-up, the modifiable lifestyle factors of physical activity, nutrition, and body weight have not yet gained enough attention regarding potential cardiovascular risk reduction. OBJECTIVE: These practical recommendations aim to provide summarised information and practical implications to paediatricians and health professionals treating childhood cancer survivors to reduce the risk of cardiovascular late effects. METHODS: The content derives from either published guidelines or expert opinions from Association of European Paediatric and Congenital Cardiology working groups and is in accordance with current state-of-the-art. RESULTS: All usual methods of prevention and screening regarding the risk, monitoring, and treatment of occurring cardiovascular diseases are summarised. Additionally, modifiable lifestyle factors are explained, and clear practical implications are named. CONCLUSION: Modifiable lifestyle factors should definitely be considered as a cost-effective and complementary approach to already implemented follow-up care programs in cardio-oncology, which can be actively addressed by the survivors themselves. However, treating physicians are strongly encouraged to support survivors to develop and maintain a healthy lifestyle, including physical activity as one of the major influencing factors. This article summarises relevant background information and provides specific practical recommendations on how to advise survivors to increase their level of physical activity.

Effects of cohort, genotype, variant, and maternal ß-blocker treatment on foetal heart rate predictors of inherited long QT syndrome.

AIMS: In long QT syndrome (LQTS), primary prevention improves outcome; thus, early identification is key. The most common LQTS phenotype is a foetal heart rate (FHR) < 3rd percentile for gestational age (GA) but the effects of cohort, genotype, variant, and maternal ß-blocker therapy on FHR are unknown. We assessed the influence of these factors on FHR in pregnancies with familial LQTS and developed a FHR/GA threshold for LQTS. METHODS AND RESULTS: In an international cohort of pregnancies in which one parent had LQTS, LQTS genotype, familial variant, and maternal ß-blocker effects on FHR were assessed. We developed a testing algorithm for LQTS using FHR and GA as continuous predictors. Data included 1966 FHRs at 7-42 weeks' GA from 267 pregnancies/164 LQTS families [220 LQTS type 1 (LQT1), 35 LQTS type 2 (LQT2), and 12 LQTS type 3 (LQT3)]. The FHRs were significantly lower in LQT1 and LQT2 but not LQT3 or LQTS negative. The LQT1 variants with non-nonsense and severe function loss (current density or ß-adrenergic response) had lower FHR. Maternal ß-blockers potentiated bradycardia in LQT1 and LQT2 but did not affect FHR in LQTS negative. A FHR/GA threshold predicted LQT1 and LQT2 with 74.9% accuracy, 71% sensitivity, and 81% specificity. CONCLUSION: Genotype, LQT1 variant, and maternal ß-blocker therapy affect FHR. A predictive threshold of FHR/GA significantly improves the accuracy, sensitivity, and specificity for LQT1 and LQT2, above the infant's a priori 50% probability. We speculate this model may be useful in screening for LQTS in perinatal subjects without a known LQTS family history.

Preventing and Treating Torsades de Pointes in the Mother, Fetus and Newborn in the Highest Risk Pregnancies with Inherited Arrhythmia Syndromes.

The number of women of childbearing age who have been diagnosed in childhood with ion channelopathy and effectively treated using beta blockers, cardiac sympathectomy, and life-saving cardiac pacemakers/defibrillators is increasing. Since many of these diseases are inherited as autosomal dominant, offspring have about a 50% risk of having the disease, though many will be only mildly impacted during fetal life. However, highly complex delivery room preparation is increasingly needed in pregnancies with inherited arrhythmia syndromes (IASs). However, specific Doppler techniques show meanwhile a better understanding of fetal electrophysiology. The advent of fetal magnetocardiography (FMCG) now allows the detection of fetal Torsades de Pointes (TdP) ventricular tachycardia and other LQT-associated arrhythmias (QTc prolongation, functional second AV block, T-wave alternans, sinus bradycardia, late-coupled ventricular ectopy and monomorphic VT) in susceptible fetuses during the second and third trimester. These types of arrhythmias can be due to either de novo or familial Long QT Syndrome (LQTS), Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), or other IAS. It is imperative that the multiple specialists involved in the antenatal, peripartum, and neonatal care of these women and their fetuses/infants have the optimal knowledge, training and equipment in order to care for these highly specialized pregnancies and deliveries. In this review, we outline the steps to recognize symptomatic LQTS in either the mother, fetus or both, along with suggestions for evaluation and management of the pregnancy, delivery, or post-partum period impacted by LQTS.

A Small Scale Optically Pumped Fetal Magnetocardiography System.

INTRODUCTION: Fetal magnetocardiography (fMCG) is considered the best technique for diagnosis of fetal arrhythmia. It is superior to more widely used methods such as fetal, fetal electrocardiography, and cardiotocography for evaluation of fetal rhythm. The combination of fMCG and fetal echocardiography can provide a more comprehensive evaluation of fetal cardiac rhythm and function than is currently possible. In this study, we demonstrate a practical fMCG system based on optically pumped magnetometers (OPMs). METHODS: Seven pregnant women with uncomplicated pregnancies underwent fMCG at 26-36 weeks' gestation. The recordings were made using an OPM-based fMCG system and a person-sized magnetic shield. The shield is much smaller than a shielded room and provides easy access with a large opening that allows the pregnant woman to lie comfortably in a prone position. RESULTS: The data show no significant loss of quality compared to data acquired in a shielded room. Measurements of standard cardiac time intervals yielded the following results: PR = 104 ± 6 ms, QRS = 52.6 ± 1.5 ms, and QTc = 387 ± 19 ms. These results are compatible with those from prior studies performed using superconducting quantum interference device (SQUID) fMCG systems. CONCLUSIONS: To our knowledge, this is the first European fMCG device with OPM technology commissioned for basic research in a pediatric cardiology unit. We demonstrated a patient-friendly, comfortable, and open fMCG system. The data yielded consistent cardiac intervals, measured from time-averaged waveforms, compatible with published SQUID and OPM data. This is an important step toward making the method widely accessible.

Anxiety and Depression Levels in Parents after Counselling for Fetal Heart Disease.

The progress in fetal cardiology allows for the early diagnosis of congenital heart defects, but there is still a lack of data on the psychological situation of parents expecting a child with a congenital heart defect. In this cross-sectional study, 77 parents (45 women and 32 men) expecting a child with a heart defect were interviewed with different questionnaires. The standardized Hospital Anxiety and Depression Scale (HADS) questionnaire was used to assess the psychological state of the parents. Various statistical procedures were performed to determine the prevalence, risk factors, and predictors of anxiety and depression. The prevalence for prenatal anxiety was 11.8% and for depressed mood 6.6%, whereas the postnatal prevalence was 25% for anxiety and 16.7% for depressed mood. The mother is influential in protecting against depression as a contact person (p = 0.035). Women were more affected by anxiety and depression than men (p = 0.036). A significant and positive correlation was observed between anxiety and depression before birth (ρ = 0.649, p < 0.001) and after birth (ρ = 0.808, p < 0.001). The level of education correlated negatively with depression (p = 0.016) and anxiety (p = 0.017) before birth. Significantly higher anxiety and depression scores were not observed among health and social workers (p = 0.084), first-time mothers (p = 0.190), and parents whose pregnancies were due to medical assistance (p = 0.051). Close collaboration between maternal-fetal care units, pediatric cardiologists and psychiatric/psychosomatic disciplines is a possible strategy to reduce stress in parents. Therefore, an expert team of professionals, educating with understandable terms and sufficient knowledge about fetal heart disease in parenting counseling, is required. The support of affected parents can positively impact the treatment of the child and should be integrated into the daily routine of the clinic.

Perinatal Outcome and its Prediction Using Longitudinal Feto-Maternal Doppler Follow-Up in Late Onset Small for Gestational Age Fetuses - A Prospective Cohort Study.

PURPOSE: To describe the perinatal outcome of a prospective cohort of late-onset small-for-gestational-age (SGA) fetuses and to test adverse perinatal outcome (APO) prediction using Doppler measurements. METHODS: Singleton pregnancies from 32 weeks with suspicion of SGA (followed-up each 2 weeks) and randomly selected healthy controls at a university hospital were included. The whole SGA group was divided into the FGR subgroup or SGA percentile 3-10 subgroup. The following Doppler measurements were evaluated prospectively: umbilical artery (UA) pulsatility index (PI), middle cerebral artery (MCA) PI, cerebro-placental ratio (CPR), and mean uterine artery (mUtA) PI. APO was defined as arterial cord blood pH ≤ 7.15 and/or 5-minute Apgar ≤ 7 and/or emergency operative delivery and/or admission to the neonatal unit. Induction of labor was indicated according to a stage-based protocol. RESULTS: A total of 149 SGA and 143 control fetuses were included. The number of operative deliveries was similar between both groups (control: 29 %, SGA: 28 %), especially the cesarean delivery rate after the onset of labor (11 % vs. 10 %). Most SGA cases ended up in induction of labor (61 % vs. 31 %, p < 0.001). The areas under the curve (AUC) for APO prediction were similar using the last UA PI, MCA PI, CPR, and mUtA PI and barely reached 0.60. The AUC was best for the FGR subgroup, using the minimal CPR or maximum mUtA PI z-score of all longitudinal measurements (AUC = 0.63). CONCLUSION: SGA fetuses do not have a higher rate of operative delivery if managed according to a risk stratification protocol. Prediction of APO is best for SGA and FGR using the "worst" CPR or mUtA PI but it remains moderate.

Fetal Bradycardia Caused by Monogenic Disorders-A Review of the Literature.

Introduction: The standard obstetric definition of fetal bradycardia is a sustained fetal heart rate < 110 bpm over at least 10 min. Fetal bradycardia can be the first and only prenatal presentation of a heart disease. We present an overview on different genetic disorders that should be taken into consideration in case of diagnosed fetal bradycardia. Methods: A literature review was conducted using a PubMed- and OMIM-based search for monogenetic disorders causing fetal bradycardia in September 2022. Results: The review on the literature identified nine monogenic diseases that could lead to fetal bradycardia. Four of these disorders can be associated with extracardiac findings. Discussion: Genetic testing should be considered in cases with fetal bradycardia, especially in cases of additional extracardiac findings. Broad sequencing techniques and improved prenatal phenotyping could help to establish a diagnosis in an increasing number of cases.

Fetal Arrhythmia Diagnosis and Pharmacologic Management.

One of the most successful achievements of fetal intervention is the pharmacologic management of fetal arrhythmias. This management usually takes place during the second or third trimester. While most arrhythmias in the fetus are benign, both tachy- and bradyarrhythmias can lead to fetal hydrops or cardiac dysfunction and require treatment under certain conditions. This review will highlight precise diagnosis by fetal echocardiography and magnetocardiography, the 2 primary means of diagnosing fetuses with arrhythmia. Additionally, transient or hidden arrhythmias such as bundle branch block, QT prolongation, and torsades de pointes, which can lead to cardiomyopathy and sudden unexplained death in the fetus, may also need pharmacologic treatment. The review will address the types of drug therapies; current knowledge of drug usage, efficacy, and precautions; and the transition to neonatal treatments when indicated. Finally, we will highlight new assessments, including the role of the nurse in the care of fetal arrhythmias. The prognosis for the human fetus with arrhythmias continues to improve as we expand our ability to provide intensive care unit-like monitoring, to better understand drug treatments, to optimize subsequent pregnancy monitoring, to effectively predict timing for delivery, and to follow up these conditions into the neonatal period and into childhood. Coordinated initiatives that facilitate clinical fetal research are needed to address gaps in knowledge and to facilitate fetal drug and device development.

Contribution of Fetal Magnetocardiography to Diagnosis, Risk Assessment, and Treatment of Fetal Arrhythmia.

Background Fetal echocardiography has been the mainstay of fetal arrhythmia diagnosis; however, fetal magnetocardiography (fMCG) has recently become clinically available. We sought to determine to what extent fMCG contributed to the precision and accuracy of fetal arrhythmia diagnosis and risk assessment, and in turn, how this altered pregnancy management. Methods and Results We reviewed fMCG tracings and medical records of 215 pregnancies referred to the Biomagnetism Laboratory, UW-Madison, over the last 10 years, because of fetal arrhythmia or risk of arrhythmia. We compared referral diagnosis and treatment with fMCG diagnosis using a rating scale and restricted our review to the 144 subjects from the tachycardia, bradycardia/AV block, and familial long QT syndrome categories. Additional fMCG findings beyond those of the referring echocardiogram, or an alternative diagnosis were seen in 117/144 (81%), and 81 (56%) were critical changes. Eight (5.5%) had resolution of arrhythmia before fMCG. At least moderate changes in management were seen in 109/144 (76%) fetuses, of which 35/144 (24%) were major. The most diverse fMCG presentation was long QT syndrome, present in all 3 referral categories. Four of 5 stillbirths were seen with long QT syndrome. Nine fetuses showed torsades de pointes ventricular tachycardia, of which only 2 were recognized before fMCG. Conclusions FMCG has a significant impact on prenatal diagnosis and management of arrhythmias or familial arrhythmia risk, which cannot be fully met by existing technology. The combination of fMCG and fetal echocardiography in fetal care centers will be needed in the future to optimize care.

Physical Activity in High-Risk Pregnancies.

It is known that physical activity before and during pregnancy is associated with health benefits for both the mother and fetus. The WHO recommends a minimum of 150 min per week of moderate-intensity aerobic physical activity for pregnant women. However, the majority of pregnant woman seem not to be physically active in pregnancy as recommended. In addition, the WHO recommendations do not include information on physical activity (PA) for specific target groups. This might be particularly problematic in women with assisted reproduction technologies (ART) or those who have received the fetal diagnosis of congenital heart defects (CHD). The aim of our study was to elaborate on whether assisted reproduction technologies (ART) and/or the diagnosis of fetal congenital heart defects (CHD) influence the level of PA in pregnant women, and to determine if there is a difference between PA behavior before and during pregnancy. In addition, we will evaluate whether high-risk pregnant women also reach the WHO recommendations. A non-interventional, cross-sectional, monocentric study based on two standardized questionnaires on physical activity was conducted. In total, n = 158 pregnant women were included. All of the participants were recruited from the outpatient clinics of the German Heart Center, Munich, and the Klinikverbund Kempten-Oberallgäu, Germany. Pregnant women after ART (n = 18), with fetal CHD (n = 25) and with both ART and CHD (n = 8) could be included. A total of 107 pregnant women served as healthy controls. Women, after ART, showed a significantly reduced level of physical activity (p = 0.014) during pregnancy compared to women who became pregnant naturally. Additionally, less (p < 0.001) and lighter (p = 0.002) physical activity was observed in all groups during pregnancy compared to those before pregnancy. An increase in maternal age increases the likelihood of CHD (p < 0.001) and decreases the level of physical activity before pregnancy (p = 0.012). The overall level of physical activity decreased in healthy and high-risk pregnancies, and only a quarter (26.49%) of all pregnant women reached the WHO recommendations. Further research for the specific target groups is highly recommended in order to promote and increase physical activity in ART and CHD pregnancies.

It Is Not Carved in Stone-The Need for a Genetic Reevaluation of Variants in Pediatric Cardiomyopathies.

(1) Background: In cardiomyopathies, identification of genetic variants is important for the correct diagnosis and impacts family cascade screening. A classification system was published by the American College of Medical Genetics and Genomics (ACMG) in 2015 to standardize variants' classification. The aim of the study was to determine the rate of reclassification of previously identified variants in patients with childhood-onset cardiomyopathies. (2) Methods: Medical records of patients and their relatives were screened for clinical and genetic information at the Department of Congenital Heart Defects and Pediatric Cardiology, German Heart Center Munich. Patients without an identified genetic variant were excluded from further analyses. Previously reported variants were reevaluated by the ACMG criteria in November 2021. (3) Results: Data from 167 patients or relatives of patients with childhood-onset cardiomyopathy from 137 families were analyzed. In total, 45 different genetic variants were identified in 71 individuals. Classification changed in 29% (13/45) with the greatest shift in "variants of unknown significance" to "(likely) benign" (9/13). (4) Conclusions: In patients with childhood-onset cardiomyopathies, nearly a third of reported genetic variants change mostly to more benign classes upon reclassification. Given the impact on patient management and cascade screening, this finding underlines the importance of continuous genetic counseling and variant.

The aorto-left ventricular tunnel from a fetal perspective: Original case series and literature review.

INTRODUCTION: Aorto-left ventricular tunnel (ALVT) accounts for <0.1% of congenital heart defects. Evidence on the prognosis from a fetal perspective is limited. With this retrospective international case series, we provide information on the outcome of fetuses with ALVT. METHODS: All members of the Association for European Pediatric and Congenital Cardiology's (AEPC) fetal working group and fetal medicine units worldwide were invited for participation. We observed antenatal parameters, neonatal outcome and postnatal follow-up. Additionally, a systematic search of the literature was performed. RESULTS: Twenty fetuses with ALVT were identified in 10 participating centers (2001-2019). Fetal echocardiographic characteristics of ALVT included an increased cardiac-thorax ratio (95%), left ventricular end-diastolic diameter (90%) and a dysplastic aortic valve (90%). Extracardiac malformations were rare (5%). Eight fetuses died at a median gestational age (GA) of 21 + 6 weeks (range, 19-24): all showed signs of hydrops prior to 24 weeks or at autopsy. All others (60%, 12/2) were live-born (median GA 38 + 4, range 37-40), underwent surgery and were alive at last follow up (median 3.2 years, range 0.1-17). The literature reported 22 ALVT fetuses with similar outcome. CONCLUSIONS: In the absence of fetal hydrops, ALVT carries a good prognosis. Fetuses who survive to 24 weeks without hydrops are likely to have a good outcome.

Cardiovascular outcome of former late-onset small-for-gestational-age children at 1 year of age: CURIOSA study.

OBJECTIVE: Late-onset small-for-gestational-age (SGA) fetuses usually show normal uterine artery Doppler and were long considered to have a good peri- and postnatal outcome. Recently, these fetuses were identified to have a risk factor for cardiovascular disease. The aim of our study was to evaluate former SGA children concerning their cardiovascular risk and nutrition behavior at the age of 1 year. METHODS: We performed a prospective longitudinal cohort study at the University Hospital "Klinikum rechts der Isar" of the Technical University of Munich. Singleton pregnancies from 32 weeks with suspicion of SGA and healthy control pregnancies were included. RESULTS: A total of 100 former SGA children and 113 controls with normal weight (AGA) were examined at 1 year of age. Drop-out for 1-year follow-up was 27%. SGA children had significantly higher systolic (92.8 ± 9.8 mmHg vs. 87.5 ± 10.7 mmHg, p = 0.001), diastolic (63.1 ± 8.5 mmHg vs. 60.0 ± 10.3 mmHg, p = 0.028) and mean (73.0 ± 7.8 vs. 69.2 ± 9.7 mmHg, p = 0.004) blood pressure than AGA children. Comparing two breastfeeding periods (0-4 months vs. > 7 months), a downward trend in blood pressure values for longer breastfeeding periods was shown. CONCLUSION: Our study showed that even late-onset small-for-gestational-age fetuses seem to have cardiovascular problems, although they were previously thought to be "healthy". Up to now, blood pressure measurement is not part of indicated health checks in former SGA or even fetal growth-restricted children which should be changed. Further studies are needed to investigate cardiovascular prevention programs in children.

Parents' Perspectives on Counseling for Fetal Heart Disease: What Matters Most?

After diagnosis of congenital heart disease (CHD) in the fetus, effective counseling is considered mandatory. We sought to investigate which factors, including parental social variables, significantly affect counseling outcome. A total of n = 226 parents were recruited prospectively from four national tertiary medical care centers. A validated questionnaire was used to measure counseling success and the effects of modifiers. Multiple linear regression was used to assess the data. Parental perception of interpersonal support by the physician (ß = 0.616 ***, p = 0.000), counseling in easy-to-understand terms (ß = 0.249 ***, p = 0.000), and a short period of time between suspicion of fetal CHD, seeing a specialist and subsequent counseling (ß = 0.135 **, p = 0.006) significantly improve "overall counseling success". Additional modifiers (e.g., parental native language and age) influence certain subdimensions of counseling such as "trust in medical staff" (language effect: ß = 0.131 *, p = 0.011) or "perceived situational control" (age effect: ß = 0.166 *, p = 0.010). This study identifies independent factors that significantly affect counseling outcome overall and its subdimensions. In combination with existing recommendations our findings may contribute to more effective parental counseling. We further conclude that implementing communication skills training for specialists should be considered essential.

Do children with congenital heart defects meet the vaccination recommendations? Immunisation in children with congenital heart defects.

INTRODUCTION: Congenital heart defects (CHDs) are the most common congenital malformations. Patients with CHD have a higher morbidity and mortality rate and are at greater risk for infectious diseases. The risk might even be higher if complex CHD occurs and if CHD is associated with additional co-morbidities. Therefore, immunisations in these children are essential. MATERIALS AND METHODS: Individuals were recruited at the outpatient centre of the Department of Congenital Heart Defects and Pediatric Cardiology at the German Heart Center Munich in the time between February 2016 and February 2017. Included were children between 23 months and 17 years and a diagnosis of CHD. The vaccination certificate aimed to assess the immunization status. RESULTS: In total, 657 children with CHD were included and analysed. Regarding primary immunisation, only 34 % (n = 221) of the children reached the complete vaccination status within the allowed catch-up time. Among these primary immunisation rates, vaccinations against Hepatitis B, Meningococci, Varicella and Pneumococci were found to have the lowest coverage with all being below 80%. The vaccination rate was partly influenced by the previously performed number of surgeries but not by the diagnosis of specific genetic diseases. At the age of school entry, the immunisation rate in children with CHD was also lower than in the comparable healthy population. CONCLUSION: The vaccination coverage rate in children with CHD is lower than in comparable healthy children, although this is a vulnerable patient group. Further education of parents and treating physicians of children with CHD regarding vaccination is still needed.

Myocardial deformation analysis in late-onset small-for-gestational-age and growth-restricted fetuses using two-dimensional speckle tracking echocardiography: a prospective cohort study.

OBJECTIVES: An association between fetal growth restriction (FGR) and increased predisposition to cardiovascular disease (CVD) is suggested. The aim of this study was to evaluate subclinical signs of fetal cardiac remodeling in late-onset small-for-gestational-age (SGA) and growth-restricted fetuses using two-dimensional speckle tracking echocardiography (2D-STE). METHODS: This is a prospective cohort study, including 117 late-onset (≥32 weeks) SGA (birthweight≤10th centile) fetuses and 102 gestational age matched controls. A subgroup analysis was performed: FGR was defined based on either BW (0.05). Regarding global and segmental LPSS and LSR values of LV/RV, subgroup analysis revealed no significant difference between the FGR (n=81), SGA centile 3-10 (n=36) and control group. CONCLUSIONS: A mild degree of placental dysfunction seems not to influence myocardial deformation properties measured by 2D-STE.

The Impact of Gestational Diabetes in Pregnancy on the Cardiovascular System of Children at One Year of Age.

Gestational diabetes mellitus (GDM) is a common complication in pregnancy. The effect of GDM on the cardiovascular system after birth is still unclear. Between August 2015 and December 2018, 205 pregnant women were included in the prospective controlled observational study. Patients with GDM were assigned to the study group (n = 99), whereas (n = 107) healthy women served as controls. Postnatal follow up of their offspring was performed at 12 months of age. All included children (n = 125) underwent a specific standardized protocol including anthropometric data, such as weight, height, body mass index (BMI), blood pressure (BP) recordings and ultrasound measurements of the abdominal aortic intima-media-thickness (IMT). Furthermore, at least 10 min 3-channel electrocardiogram recording was done to evaluate the autonomic nervous system (ANS) by phase rectified signal averaging. There were no significant differences in anthropometric data between the groups, neither in the blood pressure nor in the intima-media-thickness of the aorta abdominals. However, in the study group, significantly lower average acceleration capacity (AAC) (study group -20.10 ± 3.04 ms, control group -18.87 ± 4.00 ms, p = 0.02) was found, indicating ANS activation at one year of age. Further studies are required to determine if these results are persistent and if these findings have long-term effects.
