Background: Cardiovascular disease (CVD) in pregnancy is a major cause of maternal morbidity and mortality, accounting for nearly one-third of pregnancy-related deaths worldwide. Physiological adaptations—expanded plasma volume, increased cardiac output, and a prothrombotic state—represent a natural cardiovascular stress test that may precipitate decompensation or unmask subclinical disease. Aim: This review critically examines contemporary evidence and international guidelines on the management of pregnancy-related cardiovascular disorders, focusing on pathophysiological mechanisms, diagnostic challenges, and therapeutic controversies. Content: The discussion centers on three high-impact clinical domains: (1) peripartum and preexisting cardiomyopathies, emphasizing mechanisms, prognosis, and the role of bromocriptine; (2) anticoagulation management in women with mechanical prosthetic valves, balancing maternal safety and fetal protection; and (3) hypertensive disorders of pregnancy, highlighting recent evidence from the CHAP and WILL trials and their implications for long-term cardiovascular prevention. Comparative analysis of ESC 2025 and AHA 2020 recommendations reveals broad consensus but persistent discrepancies in anticoagulation targets, postpartum surveillance, and follow-up strategies. Perspectives: Endothelial dysfunction, angiogenic imbalance, and systemic inflammation emerge as shared mechanisms linking diverse pregnancy-related cardiovascular conditions. Strengthening multidisciplinary care through Pregnancy Heart Teams, integrating obstetric and cardiologic expertise, and establishing structured postpartum follow-up pathways are essential to improve outcomes.

Background: The fetal mechanical PR interval (mPR), measured using pulsed-wave Doppler, is a widely used parameter to assess atrioventricular conduction in fetuses, particularly in cases at risk of developing atrioventricular (AV) block. However, the physiological factors that influence mPR readings are not fully understood. This study aimed to identify determinants affecting the measurement of the mPR interval using the mitral valve/aorta (MV/Ao) Doppler method in a cohort of structurally normal fetuses. Methods: We retrospectively analyzed 925 fetuses with normal echocardiographic findings and no structural cardiac or extracardiac anomalies. Correlation analysis, group comparisons, trend testing, and multivariable modeling were performed to assess the impact of biometric and Doppler parameters on mPR interval measurements. Results: The median mPR interval across the cohort was 116 ms (interquartile range: 108–123 ms). Fetuses were categorized into four gestational age groups (≤19 weeks, 20–23 weeks, 24–27 weeks, and ≥28 weeks). Significant differences in mPR were observed between gestational age groups (p < 0.01), with a positive trend across increasing gestational age (p < 0.0001). The strongest correlation was an inverse relationship between mPR and fetal heart rate (FHR) (ρ = −0.256, p < 0.01). Multivariable regression identified five independent predictors of mPR: lower FHR, greater biparietal diameter (BPD), larger pulmonary valve diameter (PVD), increased fronto-occipital diameter (FOD), and lower umbilical artery pulsatility index (UA PI). The final model explained approximately 9.9% of the variance in mPR interval (R² = 0.099). Conclusions: The fetal mPR interval increases with gestational age and is primarily influenced by fetal heart rate, even after adjusting for other factors. Certain biometric and Doppler parameters also contribute modestly to mPR variation. These findings highlight the importance of accounting for physiological variability when interpreting mPR measurements in clinical fetal cardiology. Full article

Background and Clinical Significance: This article explores the application of fetal speckle tracking technology in evaluating critical aortic stenosis (AS) in fetuses, highlighting its potential for predicting neonatal outcomes. Case Presentation: We present two cases of fetuses diagnosed with critical AS and associated complications at late gestation. Case 1 demonstrated preserved left ventricular function, as indicated by favorable global strain (GS), fractional area change (FAC), and ejection fraction (EF) values, despite critical conditions. This infant underwent successful postnatal interventions and was discharged after an extended NICU stay. In contrast, Case 2 exhibited severely compromised left ventricular function with significantly reduced GS, FAC, and EF parameters, leading to a tragic outcome despite intensive management. Conclusions: Our findings suggest that innovative echocardiographic parameters such as GS, FAC, and EF for the left ventricle are crucial in prognostic evaluations for fetuses with critical AS. The study underscores the importance of advancements in fetal cardiology and the need for further research to enhance prognostic assessments and improve clinical outcomes in affected neonates.

Background: While prenatal diagnosis of congenital heart disease is increasingly common, and communication is essential to minimizing familial stress, little is known about how the fetus is discussed in this setting. This study observed how clinicians and families refer to the fetus during initial fetal cardiology consultations. Methods: Initial fetal cardiology consultations from one institution were recorded and transcribed verbatim. A codebook was developed and used to code the transcripts. Codes included any reference to the fetus and any attribution of agency or mental states to the fetus. Results: Nineteen consultations performed by five clinicians from one academic institution were included. Clinicians and families most frequently referred to the fetus using personal terminology (e.g., third-person pronouns, a given name, or “son” or “daughter”). Impersonal terminology (e.g., “baby”) was used less frequently, followed by medical terminology (e.g., “fetus”), which was only used in two consultations. In about half of the consultations, clinicians conferred agency or mental states on the fetus by attributing actions, emotions, or knowledge to the fetus. Conclusions: Fetal cardiology clinicians primarily use personal terminology when referring to the fetus during initial consultations. Familial preferences need to be evaluated to optimize communication and support. Full article

Background and Clinical Significance: Brugada syndrome (BrS) is a rare inherited cardiac channelopathy, often associated with SCN5A loss-of-function mutations. Clinical presentations range from asymptomatic to malignant arrhythmias and sudden cardiac death. Physiological and pharmacological stressors affecting sodium channel function—such as pyrexia, certain medications, and possibly pregnancy—may unmask or exacerbate arrhythmic risk. However, there is limited information regarding pregnancy and obstetric outcomes. Obstetric management remains largely informed by isolated case reports and small case series. A literature review was conducted using OVID Medline and Embase, identifying case reports, case series, and one retrospective cohort study reporting clinical presentation, obstetric management, and outcomes in maternal BrS. A case is presented detailing coordinated multidisciplinary input, antenatal surveillance, and intrapartum and postpartum care to contribute to the growing evidence base guiding obstetric care in this complex setting. Case Presentation: A 30-year-old G2P0 woman with asymptomatic BrS (SCN5A-positive) was referred at 31 + 5 weeks’ gestation for multidisciplinary antenatal care. Regular review and collaborative planning involving cardiology, anaesthetics, maternal–fetal medicine, and obstetrics guided a plan for vaginal delivery with continuous cardiac and fetal monitoring. At 38 + 0 weeks, the woman presented with spontaneous rupture of membranes and underwent induction of labour. A normal vaginal delivery was achieved without arrhythmic events. Epidural block with ropivacaine and local anaesthesia with lignocaine were well tolerated, and 24 h postpartum monitoring revealed no abnormalities. Conclusions: This case adds to the limited but growing literature suggesting that with individualised planning and multidisciplinary care, pregnancies in women with BrS can proceed safely and without complication. Ongoing case reporting is essential to inform future guidelines and optimise maternal and fetal outcomes. Full article

Cardiac disease remains a leading cause of maternal morbidity and mortality, particularly in developed countries where improved survival has increased the number of pregnant patients with congenital heart disease. The physiological changes of pregnancy, such as increased blood volume, cardiac output, and hypercoagulability, can exacerbate preexisting cardiac conditions, posing significant anesthetic challenges during cesarean delivery. This review outlines anesthetic strategies for parturients with structural or functional cardiac disease, emphasizing individualized, multidisciplinary care. We examine general and regional anesthesia approaches, intraoperative monitoring, and hemodynamic goals, including fluid balance, venous return optimization, and myocardial oxygen demand reduction. Preoperative risk stratification and coordination with cardiology and obstetric teams are essential. Future efforts should aim to standardize protocols and improve maternal–fetal outcomes through evidence-based anesthetic planning. Full article

Gender-specific cardiology has gained increasing recognition in recent years, emphasizing the need for tailored management strategies for women with cardiovascular disease. Among these, cardiomyopathies—dilated, arrhythmogenic, hypertrophic, and restrictive—pose unique challenges throughout a woman’s reproductive life, affecting contraception choices, pregnancy outcomes, and breastfeeding feasibility. Despite significant advances in cardiovascular care, there is still limited guidance on balancing maternal safety and neonatal well-being in this complex setting. This review provides a comprehensive overview of the current evidence on reproductive counseling, pregnancy management, and postpartum considerations in women with cardiomyopathies. We discuss the cardiovascular risks associated with each cardiomyopathy subtype during pregnancy, highlighting risk stratification tools and emerging therapeutic strategies. Additionally, we address the safety and implications of breastfeeding, an often overlooked but increasingly relevant aspect of postpartum care. A multidisciplinary approach involving cardiologists, gynecologists, obstetricians, and anesthesiologists is crucial to optimizing maternal and fetal outcomes. Improved risk assessment, tailored patient counseling, and careful management strategies are essential to ensuring safer reproductive choices for women with cardiomyopathy. From now on, greater attention is expected to be given to bridging existing knowledge gaps, promoting a more personalized and evidence-based approach to managing these patients throughout different stages of reproductive life.

Background: Tricuspid regurgitation (TR) is increasingly recognized as a detectable finding during routine fetal echocardiography. Although previous studies have explored its potential role as an indirect marker for congenital heart disease (CHD) in the first trimester, the prognostic significance of isolated mild TR in chromosomally normal and low-risk fetuses during the second and third trimesters remains unclear. Clarifying the clinical relevance of this commonly encountered Doppler finding is essential to guide appropriate prenatal management and avoid unnecessary interventions in low-risk pregnancies. Materials and Methods: This retrospective study reviewed fetal echocardiography reports of 1592 pregnant women referred to a pediatric cardiology clinic after the 20th gestational week between 1 January 2024 and 1 January 2025. Following exclusion criteria, 1072 low-risk pregnancies were included. A total of 136 fetuses with TR were identified, and among them, postnatal echocardiographic outcomes of 60 neonates who underwent transthoracic echocardiography within the first 10 days after birth were analyzed. Results: Among the 1072 low-risk pregnancies included in the study, a total of 136 fetuses were diagnosed with TR on fetal echocardiography. The majority of these cases were characterized as mild and isolated, without accompanying structural abnormalities. Postnatal echocardiographic assessments revealed no major congenital cardiac anomalies, reinforcing the interpretation that isolated mild TR in the context of low-risk pregnancies represents a benign and likely transient physiological finding. Conclusion: Isolated mild TR, particularly in low-risk and chromosomally normal pregnancies, appears to be a transient and clinically insignificant finding. These results support the interpretation of fetal TR in the context of overall clinical and structural evaluation, helping to avoid unnecessary interventions and reduce parental anxiety.

Background/Objectives: The aim of this study was to determine the prevalence of functional cardiovascular anomalies detected on fetal echocardiography in third-trimester large-for-gestational-age (LGA) fetuses, who were subsequently born as macrosomic newborns with a birth weight exceeding 4000 g. Methods: A retrospective study was conducted on 1002 fetuses examined during the third trimester at our fetal cardiology center between 2018 and 2024. All fetuses were classified as having “normal heart anatomy” (NHA). Statistical analysis was performed using Microsoft Excel 2024, Statistica 13.1, and EasyMedStat (version 3.37.1). A p-value of <0.05 was considered statistically significant. Results: The 1002 fetuses were divided into two groups. The study group (NHA-LGA) consisted of 167 fetuses born with a weight of >4000 g and the control group (NHA-AGA) was made up of 835 fetuses with a birth weight between 2500 and 4000 g. In the NHA-LGA group, 24 fetuses (14.4%) experienced ductal constriction (DC), while in the NHA-AGA group, it was 11 (1.3%) fetuses (p < 0.00001). Myocardial hypertrophy was observed in 30 fetuses (18.0%) in the NHA-LGA group versus 72 (8.6%) in the NHA-AGA group (p < 0.0003). Additionally, cardiomegaly was noted in 95 fetuses (11.4%) in the NHA-LGA group, compared to 37 (4.4%) in the NHA-AGA group (p < 0.0004). Conclusions: LGA fetuses with normal heart anatomy may present with functional cardiovascular anomalies, including ductal constriction, myocardial hypertrophy, and cardiomegaly. In our cohort, such anomalies were identified in up to 51% of cases. These findings suggest that targeted fetal echocardiographic screening in macrosomic fetuses could be clinically valuable, even in the absence of structural heart defects, and may aid in the early identification of functional cardiac alterations that could impact perinatal management.

This case report describes a fetus diagnosed with complete atrioventricular block (CAVB) associated with positive maternal anti-Ro and anti-La antibodies, referred to our fetal cardiology unit at 25 weeks of gestation. The diagnosis of systemic lupus erythematosus (SLE) was established during the investigation of the fetal condition. Oral dexamethasone was initiated and well tolerated, with no adverse effects reported throughout the remainder of the pregnancy. The fetal heart rate (HR) remained above 50 bpm, and, therefore, no beta-sympathomimetic agents were administered. Due to progressive reduction in myocardial contractility and the appearance of early signs of endocardial fibroelastosis, intravenous immunoglobulin (IVIG) therapy was initiated. The patient was hospitalized for the infusion, which was well tolerated without complications, and a second IVIG cycle was administered four weeks later. Significant improvement in ventricular contractility and reduction in fibroelastosis were observed. As reported in the literature, no chronotropic effect was noted, and fetal HR remained stable after treatment. Weekly monitoring of cardiovascular profile score and fetal HR was maintained, with the score consistently remaining at 8 throughout gestation, supporting continued outpatient management. Delivery occurred at 36 weeks and 3 days due to spontaneous preterm labor. A male neonate weighing 3025 g was delivered with Apgar scores of 8 and 9, and an initial heart rate of 84 bpm. Neonatal electrocardiography confirmed persistent CAVB, and the newborn was monitored in the neonatal intensive care unit. At follow-up, the infant remains clinically stable and has not required permanent pacemaker implantation. Full article

Background/Objectives: The main goal of this study was to determine whether ductal constriction in the third trimester of a pregnancy during fetal echocardiography examination has an impact on the neonatal clinical condition during the first days after birth. Methods: A retrospective study was based on 348 newborns who were examined during their fetal life in the third trimester of a pregnancy in our fetal cardiology center. They were divided into two groups: the study group (n = 49): neonates with “normal heart anatomy” (NHA), assessed by fetal echocardiography (ECHO) examination and prenatally diagnosed ductal constriction (NHA-DC); and the control group (n = 299): NHA neonates without DC (NHA-NDC). Results: Prenatally, DC was associated with other functional abnormalities, such as myocardial hypertrophy, cardiomegaly, tricuspid regurgitation, pericardial effusion and abnormal flow through foramen ovale. Neonates with prenatally diagnosed DC in 43% of cases presented with elevated neonatal bilirubin levels requiring phototherapy treatment (p < 0.006). In the study group 27% of neonates showed signs of breathing difficulties in the first hours of life (p < 0.001). Neonates with a prenatal diagnosis of DC were hospitalized longer than neonates with a normal heart study (NHS) (p < 0.001). Conclusions: Neonates with a prenatal diagnosis of ductal constriction are prone to having transient respiratory problems (up to 27%) and mild neonatal hyperbilirubinemia (in presented series up to 43%). Gestational diabetes can be associated with ductal constriction. Full article

Congenital long QT syndrome (LQTS) is a group of heritable conditions that are associated with cardiac repolarization abnormalities characterized by QT prolongation on electrocardiogram and the risk of life-threatening arrhythmias. The prenatal detection of LQTS presents significant challenges for clinicians, and a multidisciplinary approach is required for optimal prenatal and postnatal management. In this comprehensive literature review, we describe strategies for the fetal diagnosis of LQTS with variable initial presentation, genetic testing in suspected fetal LQTS, the utility of fetal magnetocardiography as an additional diagnostic tool, prenatal management, and postnatal treatment. We focus on a multidisciplinary team approach including fetal cardiology, adult and pediatric electrophysiology, neonatology, maternal–fetal medicine, and genetic counselors, all playing vital roles in the comprehensive prenatal management and orchestration of postnatal treatment to optimize neonatal outcomes.

Congenital heart defects (CHDs) are the most common congenital defect, occurring in approximately 1 in 100 live births and being a leading cause of perinatal morbidity and mortality. Of note, approximately 25% of these defects are classified as critical, requiring immediate postnatal care by pediatric cardiology and neonatal cardiac surgery teams. Consequently, early and accurate diagnosis of CHD is key to proper prenatal and postnatal monitoring in a tertiary care setting. In this scenario, fetal echocardiography is considered the gold standard imaging ultrasound method for the diagnosis of CHD. However, the availability of this examination in clinical practice remains limited due to the need for a qualified specialist in pediatric cardiology. Moreover, in light of the relatively low prevalence of CHD among at-risk populations (approximately 10%), ultrasound cardiac screening for potential cardiac anomalies during routine second-trimester obstetric ultrasound scans represents a pivotal aspect of diagnosing CHD. In order to maximize the accuracy of CHD diagnoses, the views of the ventricular outflow tract and the superior mediastinum were added to the four-chamber view of the fetal heart for routine ultrasound screening according to international guidelines. In this context, four-dimensional spatio-temporal image correlation software (STIC) was developed in the early 2000s. Some of the advantages of STIC in fetal cardiac evaluation include the enrichment of anatomical details of fetal cardiac images in the absence of the pregnant woman and the ability to send volumes for analysis by an expert in fetal cardiology by an internet link. Sequentially, new technologies have been developed, such as fetal intelligent navigation echocardiography (FINE), also known as “5D heart”, in which the nine fetal cardiac views recommended during a fetal echocardiogram are automatically generated from the acquisition of a cardiac volume. Furthermore, artificial intelligence (AI) has recently emerged as a promising technological innovation, offering the potential to warn of possible cardiac anomalies and thus increase the ability of non-cardiology specialists to diagnose CHD. In the early 2010s, the advent of 3D reconstruction software combined with high-definition printers enabled the virtual and 3D physical reconstruction of the fetal heart. The 3D physical models may improve parental counseling of fetal CHD, maternal–fetal interaction in cases of blind pregnant women, and interactive discussions among multidisciplinary health teams. In addition, the 3D physical and virtual models can be an useful tool for teaching cardiovascular anatomy and to optimize surgical planning, enabling simulation rooms for surgical procedures. Therefore, in this review, the authors discuss advanced image technologies that may optimize prenatal diagnoses of CHDs. Full article

Our primary objective was to assess the effectiveness of detailed cardiovascular ultrasound screening during the first trimester, which was performed by obstetricians with intermediate experience. We collected first-trimester fetal cardiac screening data from an unselected pregnant population at RMC-Fetal Medicine Center during a study period spanning from 1 January 2010, to 31 January 2015, in order to analyze our learning curve. A pediatric cardiologist performed a follow-up assessment in cases where the examining obstetrician determined that the fetal cardiac screening results were abnormal or high-risk. Overall, 42 (0.88%) congenital heart abnormalities were discovered prenatally out of 4769 fetuses from 4602 pregnant women who had at least one first-trimester cardiac ultrasonography screening. In total, 89.2% of the major congenital heart abnormalities (27 of 28) in the following fetuses were discovered (or at least highly suspected) at the first-trimester screening and subsequent fetal echocardiography by the pediatric cardiology specialist. Of these, 96.4% were diagnosed prenatally. According to our results, the effectiveness of first-trimester fetal cardiovascular ultrasound screening conducted by moderately experienced obstetricians in an unselected (’routine’) pregnant population may reach as high as 90% in terms of major congenital heart defects, provided that equipment, quality assurance, and motivation are appropriate.

Fetal cardiology has evolved over the last 40 years and changed the timing of diagnosis and counseling of congenital heart disease, decision-making, planning for treatment at birth, and predicting future surgery from the postnatal to the prenatal period. Ethical issues in fetal cardiology transect multiple aspects of biomedical ethics including improvement in prenatal detection and diagnostic capabilities, access to equitable comprehensive care that preserves a pregnant person’s right to make decisions, access to all reproductive options, informed consent, complexity in shared decision-making, and appropriate use of fetal cardiac interventions. This paper first reviews the literature and then provides an ethical analysis of accurate and timely diagnosis, equitable delivery of care, prenatal counseling and shared decision-making, and innovation through in utero intervention.
