Artif Intell Med 2024; 153:102867. [PMID: 38723434 DOI: 10.1016/j.artmed.2024.102867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 04/02/2024] [Accepted: 04/03/2024] [Indexed: 06/11/2024]
Abstract
OBJECTIVE To develop a deep learning algorithm to perform multi-class classification of normal pediatric heart sounds, innocent murmurs, and pathologic murmurs. METHODS We prospectively enrolled children under age 18 being evaluated by the Division of Pediatric Cardiology. Parents provided consent for a deidentified recording of their child's heart sounds with a digital stethoscope. Innocent murmurs were validated by a pediatric cardiologist and pathologic murmurs were validated by echocardiogram. To augment our collection of normal heart sounds, we utilized a public database of pediatric heart sound recordings (Oliveira, 2022). We propose two novel approaches for this audio classification task. We train a vision transformer on either Markov transition field or Gramian angular field image representations of the frequency spectrum. We benchmark our results against a ResNet-50 CNN trained on spectrogram images. RESULTS Our final dataset consisted of 366 normal heart sounds, 175 innocent murmurs, and 216 pathologic murmurs. Innocent murmurs collected include Still's murmur, venous hum, and flow murmurs. Pathologic murmurs included ventricular septal defect, tetralogy of Fallot, aortic regurgitation, aortic stenosis, pulmonary stenosis, mitral regurgitation and stenosis, and tricuspid regurgitation. We find that the Vision Transformer consistently outperforms the ResNet-50 on all three image representations, and that the Gramian angular field is the superior image representation for pediatric heart sounds. We calculated a one-vs-rest multi-class ROC curve for each of the three classes. Our best model achieves an area under the curve (AUC) value of 0.92 ± 0.05, 0.83 ± 0.04, and 0.88 ± 0.04 for identifying normal heart sounds, innocent murmurs, and pathologic murmurs, respectively. CONCLUSION We present two novel methods for pediatric heart sound classification, which outperforms the current standard of using a convolutional neural network trained on spectrogram images. To our knowledge, we are the first to demonstrate multi-class classification of pediatric murmurs. Multiclass output affords a more explainable and interpretable model, which can facilitate further model improvement in the downstream model development cycle and enhance clinician trust and therefore adoption.

Abstract
The advancement of medical treatment and surgical technique, along with the invention of cardiopulmonary bypass, has allowed for long-term survival of patients with cyanotic congenital heart disease (CHD)-with many women with CHD now reaching child-bearing age and wishing to become pregnant. Pregnancy in these women is a major concern as the physiologic adaptations of pregnancy, including an increased circulating volume, increased cardiac output, reduced systemic vascular resistance, and decreased blood pressure, place a substantial load on the cardiovascular system. These changes are essential to meet the increased maternal and fetal metabolic demands and allow for sufficient placental circulation during gestation. However, in women with underlying structural heart conditions, they place an additional hemodynamic burden on the maternal body. Overall, with appropriate risk stratification, pre-conception counseling, and management by specialized cardiologists and high-risk obstetricians, most women with surgically corrected CHDs are expected to carry healthy pregnancies to term with optimization of both maternal and fetal risks. In this article, we describe the current understanding of 5 cyanotic CHDs-Tetralogy of Fallot, Transposition of the Great Arteries, Truncus Arteriosus, Ebstein's Anomaly, and Eisenmenger Syndrome-and explore the specific hemodynamic consequences, maternal and fetal risks, current guidelines, and outcomes of pregnancy in women with these conditions.

Prenatal Cardiac Ultrasound Markers of Outcomes in Ebstein's Anomaly: An International Multicenter Case Series. Pediatr Cardiol 2024:10.1007/s00246-024-03530-9. [PMID: 38825661 DOI: 10.1007/s00246-024-03530-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Accepted: 05/20/2024] [Indexed: 06/04/2024]
Abstract
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.

Abstract
Ebstein's anomaly of the tricuspid valve (EA) is an uncommon congenital cardiac malformation. It can present with atrioventricular tachycardia (AVRT), atrioventricular nodal re-entrant tachycardia (AVNRT), atrial arrhythmias, and rarely with ventricular tachycardia. The 12-lead electrocardiogram (ECG) is critically important and often diagnostic even prior to an electrophysiology study (EPS). Due to its complex anatomy, it poses particular challenges for mapping and ablation, even for an experienced electrophysiologist. In this review, we aim to provide insight into the electrophysiological perspective of EA and an in-depth analysis of the various arrhythmias encountered in diverse clinical scenarios.

Uncommon manifestation of Ebstein anomaly: A case report of apical displacement involving all tricuspid valve leaflets. Clin Case Rep 2024; 12:e8991.

Abstract
Key Clinical Message This case report presents an uncommon variant of Ebstein anomaly, where all three tricuspid valve leaflets exhibited apical displacement-a rare finding. It illustrates the complexities in diagnosing and managing such atypical presentations, with successful surgical correction through annuloplasty. The report adds valuable insights to the limited literature on this congenital heart disease. Abstract Ebstein anomaly (EA), a rare congenital heart disorder, presents with diverse clinical spectrums. This case report explores a distinctive manifestation of EA, where all three tricuspid valve (TV) leaflets exhibited apical displacement, highlighting a novel aspect in the presentation of this condition. A 44-year-old woman, under long-term medical surveillance for EA, showcased an atypical clinical trajectory marked by the apical displacement of all TV leaflets, which is uncommon in EA. Despite a predominantly asymptomatic course, recent exacerbation of symptoms prompted further evaluation. Diagnostic modalities, including echocardiography and cardiac magnetic resonance imaging, revealed severe tricuspid regurgitation concomitant with unprecedented apical displacement of the anterior, septal, and posterior tricuspid leaflets. The displacement of the anterior leaflet was contrary to typical embryonic valvular formation expectations, indicating a unique presentation within EA. The patient underwent annuloplasty surgery, which successfully rectified the anomalous TV architecture. Postoperative evaluation demonstrated mild residual tricuspid regurgitation, and the patient was discharged in stable condition. This case underscores the variability in EA presentations and accentuates the significance of tailored surgical interventions. The observation of apical displacement involving all TV leaflets adds a unique dimension to the existing EA literature, reinforcing the need for careful diagnosis and personalized treatment approaches.

Abstract
BACKGROUND Ebstein's anomaly (EA) is a rare and complex congenital heart anomaly, and the effect of surgical treatment is not ideal. This study aims to introduce our experience in management strategies, surgical techniques, and operative indications for patients with Ebstein's anomaly. METHODS A retrospective study of 258 operations was performed in 253 patients by the same cardiac surgeon in The First Hospital of Tsinghua University between March 2004 and January 2020. 32 patients had previously received cardiac surgery in other hospitals. The clinical data including diagnosis, operative indications, techniques, pathological changes, and survival rates were collected and analyzed. RESULTS Anatomical correction was performed in 203 (78.7%) operations, 1½ ventricle repair in 38 (14.7%) operations, tricuspid valve repair only in four operations (1.6%), tricuspid valve replacement in ten (3.9%), total cavopulmonary connection (TCPC) in two (0.8%), and Glenn operation in one operation (0.4%). Reoperation was performed in five patients (2.0%) during hospitalization. Among them, tricuspid valve replacement was performed in one patient, 1½ ventricle repair in two patients, and tricuspid valve annulus reinforcement in two patients. Five patients died with an early mortality rate of 2.0%. Complete atrioventricular conduction block was complicated in one patient (0.4%). A total of 244 patients was followed up (four in the 253 patients lost) with a duration of 3.0-168.0 (87.6 ± 38.4) months. Cardiac function of 244 patients improved significantly with mean New York Heart Association (NYHA) functional class recovery from 3.5 to 1.1. The mean grade of tricuspid valve regurgitation improved from 3.6 to 1.5. Three late deaths (1.2%) occurred. The survival rates at five and ten years after surgery were 98.6% and 98.2%, respectively. Reoperation was performed in five patients (2.0%) during the follow-up period. CONCLUSION Based on our management strategies and operative principles and techniques, anatomical correction of EA is capable of achieving excellent long-term results, and low rates of TCPC, 1½ ventricle repair and valvular replacement.

Abstract
Ebstein anomaly (EA) is a rare congenital heart defect characterized by abnormal development of the tricuspid valve (TV) and right ventricular myocardium. This study documents 2 dramatic cases of fetal EA characterized by hydrops and cardiomegaly, leading to intrauterine or early neonatal death. These clinical outcomes were associated with morphological abnormalities including severe tricuspid regurgitation, unguarded TV orifice, pulmonary atresia, and flattened right ventricular myocardium. This study highlights that these adverse anatomical features may result in unfavorable clinical outcomes in fetal EA. While timely identification of such features by prenatal ultrasound is crucial for providing accurate prognostic stratification and guiding treatment decisions, fetopsy may be necessary to discern EA among the spectrum of right-heart anomalies.

Abstract
Ebstein's anomaly is a rare congenital cardiac disease which is often associated with various other cardiac anomalies. However, its association with total anomalous pulmonary venous connection is extremely rare with only one case reported so far in the English literature. We report the first successful surgical correction of both Ebstein's anomaly and total anomalous pulmonary venous connection in an adult patient. Such complex scenarios may pose unique challenges in management which require a judicious approach.

Abstract
PURPOSE Ebstein anomaly (EA) and tricuspid valve dysplasia (TVD) represent uncommon congenital malformations of the tricuspid valve. The purpose of this study is to report on current perinatal outcomes of EA/TVD in our center and to investigate clinical and fetal echocardiographic predictors of perinatal mortality. METHODS AND RESULTS We performed a retrospective study among fetuses diagnosed from January 2014 to December 2023. Clinical and echocardiographic data were obtained from hospital records of Research and Education Hospital. The primary outcome was perinatal mortality. Of 21 fetuses diagnosed, there were 1 lost to follow-up, 1 termination, and 7 demises. In the live-born cohort of 12 live-born patients, 2 died before discharge, yielding an overall perinatal mortality of 50%. The median gestational age at diagnosis was 23 for non-survivors and 24 weeks for survivors. Birth weight was lower in non-survivors (2430 g vs 2990 g). Tricuspid insufficiency severity varied insignificantly. Non-survivors exhibited higher rates of hydrops, functional atresia, and absent antegrade flow (p < 0.05). Two infants with severe tricuspid insufficiency and congenital abnormalities died postnatally. The limited dataset enables further analysis for a predictive model. Notably, all non-survivors displayed hydrops, functional atresia, and absent antegrade flow, hindering definitive determination of the most impactful parameter on survival estimation. CONCLUSION Perinatal mortality remains notably elevated in fetuses with EA/TVD. The individuals at the highest risk are those with antegrade flow loss and functional atresia of pulmonary valve, this high-risk subgroup could benefit from targeted interventions, such as novel prenatal therapies or a more comprehensive perinatal approach involving optimized timing of delivery and postnatal interventional strategies.

Abstract
Advances in pediatric cardiac surgery have resulted in a recent growing epidemic of children and young adults with congenital heart diseases (CHDs). In these patients, congenital defects themselves, surgical operations and remaining lesions may alter cardiac anatomy and impact the mechanical performance of both ventricles. Cardiac function significantly influences outcomes in CHDs, necessitating regular patient follow-up to detect clinical changes and relevant risk factors. Echocardiography remains the primary imaging method for CHDs, but clinicians must understand patients' unique anatomies as different CHDs exhibit distinct anatomical characteristics affecting cardiac mechanics. Additionally, the use of myocardial deformation imaging and 3D echocardiography has gained popularity for enhanced assessment of cardiac function and anatomy. This paper discusses the role of echocardiography in evaluating cardiac mechanics in most significant CHDs, particularly its ability to accommodate and interpret the inherent anatomical substrate in these conditions.

A Twenty-Year Follow-Up of Adults with Ebstein Anomaly with Special Focus on Supraventricular Arrhythmias, Supraventricular Arrhythmias and Effectiveness of Catheter Ablation in 20-Year Follow-Up of Adults with Ebstein Anomaly. J Clin Med 2024; 13:2039. [PMID: 38610805 PMCID: PMC11012800 DOI: 10.3390/jcm13072039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 03/19/2024] [Accepted: 03/28/2024] [Indexed: 04/14/2024] Open
Abstract
Background: Ebstein anomaly (EA) is a rare congenital heart disease characterized by the apical displacement of the tricuspid leaflets, creating an enlarged functional right atrium. Supraventricular arrhythmias (SVA) are common, and catheter ablation remains challenging. SVA is considered a risk factor for sudden cardiac death in this population. Still, there are very few real-life data on the impact of SVA treated invasively or conservatively on a patient's prognosis. We aimed to analyze the incidence of SVA in adults with EA, evaluate the effectiveness of catheter ablation, and analyze the impact of SVA and catheter ablation on survival in this population. Methods and results: 71 pts (median age 53 years; range 24-84 years) with EA were evaluated retrospectively from 1988 to 2020. Forty patients (56.3%) had SVA, and eighteen of them (45.0%) required at least one catheter ablation (35 procedures in total). Indications for ablation were mostly intra-atrial reentrant tachycardia (IART) and atrioventricular reentrant tachycardia (AVRT) (14 pts [77.8% and 9 pts [50.0%], respectively. IART and AVRT coexisted in nine pts. One patient suffered from persistent atrial fibrillation. Procedural effectiveness was reported in 28 (80%) cases; over a longer follow-up (mean 12.6 ± 5.4 years), only eight (44.4%) patients were completely free from SVA after the first ablation. In total, 10 patients (14%) died due to cardiovascular events. There was no difference in survival between patients with or without SVA (p = 0.9) and between ablated and non-ablated EA individuals (p = 0.89). Conclusions: Supraventricular arrhythmia is frequent in adults with Ebstein anomaly. Patients often require more than one catheter ablation but eventually become free from arrhythmias. The imaging parameters assessed by echocardiography or cardiac magnetic resonance do not seem to be associated with ablation outcomes. The impact of supraventricular arrhythmia itself or treatment with radiofrequency ablation is questionable and should be thoroughly investigated in this population.

Abstract
Primary liver tumours in neonates with single-ventricle palliation are exceedingly rare. We present the first reported case of neonatal hepatoblastoma with severe Ebstein's anomaly following Starnes procedure. The patient's postoperative course highlights the challenges and complications in simultaneous management of these diagnoses. Transition from shunted single-ventricle physiology to bidirectional cavopulmonary connection improved end-organ function, permitting more aggressive hepatic malignancy treatment.

Abstract
Arrhythmogenic cardiomyopathy (ACM) is a genetic disease characterized by replacement of ventricular myocardium with fibrofatty tissue, predisposing the patient to ventricular arrhythmias and/or sudden cardiac death. Most cases of ACM are associated with pathogenic variants in genes that encode desmosomal proteins, an important cell-to-cell adhesion complex present in both the heart and skin tissue. Although ACM was first described as a disease predominantly of the right ventricle, it is now acknowledged that it can also primarily involve the left ventricle or both ventricles. The original right-dominant phenotype is traditionally diagnosed using the 2010 task force criteria, a multifactorial algorithm divided into major and minor criteria consisting of structural criteria based on two-dimensional echocardiographic, cardiac MRI, or right ventricular angiographic findings; tissue characterization based on endomyocardial biopsy results; repolarization and depolarization abnormalities based on electrocardiographic findings; arrhythmic features; and family history. Shortfalls in the task force criteria due to the modern understanding of the disease have led to development of the Padua criteria, which include updated criteria for diagnosis of the right-dominant phenotype and new criteria for diagnosis of the left-predominant and biventricular phenotypes. In addition to incorporating cardiac MRI findings of ventricular dilatation, systolic dysfunction, and regional wall motion abnormalities, the new Padua criteria emphasize late gadolinium enhancement at cardiac MRI as a key feature in diagnosis and imaging-based tissue characterization. Conditions to consider in the differential diagnosis of the right-dominant phenotype include various other causes of right ventricular dilatation such as left-to-right shunts and variants of normal right ventricular anatomy that can be misinterpreted as abnormalities. The left-dominant phenotype can mimic myocarditis at imaging and clinical examination. Additional considerations for the differential diagnosis of ACM, particularly for the left-dominant phenotype, include sarcoidosis and dilated cardiomyopathy. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Abstract
A combination of a ruptured sinus of Valsalva (RSOV) with Ebstein anomaly is a rare and clinically challenging entity. We describe a case of a 29-year-old female who presented with progressive dyspnoea and epigastric discomfort with symptoms and clinical findings not consistent with any single definitive diagnosis. In the primary echocardiography assessment, she was diagnosed with Ebstein anomaly. On the grounds of several unexplained clinical features and routine review echocardiography by the cardiology team, she was found to have a rare combination of Ebstein anomaly associated with RSOV. A cath study was performed to study the interplay of the hemodynamics of the two lesions, not described before in the literature, and also explain the clinical features not consistent with any one entity. We emphasize the significance of meticulous history-taking and sound clinical evaluation followed by corroboration with the diagnostic modalities for precise diagnosis and timely planned intervention in such rare associations.

Abstract
BACKGROUND AND OBJECTIVE We aimed to investigate long-term clinical and echocardiographic outcomes, including tricuspid valve durability, annular growth, and left ventricular reverse remodeling, after modified cone reconstruction in patients with Ebstein's anomaly. METHODS This was a retrospective analysis of all pediatric patients who underwent modified cone reconstruction for Ebstein's anomaly at a single tertiary center between January 2005 and June 2021. RESULTS A total of 14 pediatric patients underwent modified cone reconstruction for Ebstein's anomaly; the median age was 5.8 years (range, 0.01-16.6). There were three patients (21.4%) with Carpentier type B, ten patients with Carpentier type C (71.4%), and one patient with Carpentier type D (7.1%). There was no early or late mortality, arrhythmia, or readmission for heart failure at a 10-year follow-up. There were no cases of more than mild tricuspid stenosis or more than moderate tricuspid regurgitation during the study period, except for one patient with severe tricuspid regurgitation who underwent reoperation. The z value for tricuspid valve annular size significantly decreased immediately after the operation (2.46 vs. -1.15, p<0.001). However, from 1 year to 7 years after surgery, the z values were maintained between -1 and +1. Left ventricular end-systolic volume, end-diastolic volume, and stroke volume increased after surgery and remained elevated until seven years postoperatively. CONCLUSIONS Ebstein's anomaly in children can be repaired by modified cone reconstruction with low mortality and morbidity, good tricuspid valve durability, and annular growth relative to somatic growth.

Abstract
Myosin heavy chain gene 7 (MYH7), a sarcomeric gene encoding the myosin heavy chain (myosin-7), has attracted considerable interest as a result of its fundamental functions in cardiac and skeletal muscle contraction and numerous nucleotide variations of MYH7 are closely related to cardiomyopathy and skeletal muscle myopathy. These disorders display significantly inter- and intra-familial variability, sometimes developing complex phenotypes, including both cardiomyopathy and skeletal myopathy. Here, we review the current understanding on MYH7 with the aim to better clarify how mutations in MYH7 affect the structure and physiologic function of sarcomere, thus resulting in cardiomyopathy and skeletal muscle myopathy. Importantly, the latest advances on diagnosis, research models in vivo and in vitro and therapy for precise clinical application have made great progress and have epoch-making significance. All the great advance is discussed here.

Abstract
Ebstein's anomaly, a rare congenital heart disease, is distinguished by the failure of embryological delamination of the tricuspid valve leaflets from the underlying primitive right ventricle myocardium. Gaining insight into the genetic basis of Ebstein's anomaly allows a more precise definition of its pathogenesis. In this study, two distinct cohorts from the Chinese Han population were included: a case-control cohort consisting of 82 unrelated cases and 125 controls without cardiac phenotypes and a trio cohort comprising 36 parent-offspring trios. Whole-exome sequencing data from all 315 participants were utilized to identify qualifying variants, encompassing rare (minor allele frequency < 0.1% from East Asians in the gnomAD database) functional variants and high-confidence (HC) loss-of-function (LoF) variants. Various statistical models, including burden tests and variance-component models, were employed to identify rare variants, genes, and biological pathways associated with Ebstein's anomaly. Significant associations were noted between Ebstein's anomaly and rare HC LoF variants found in genes related to the matrisome, a collection of extracellular matrix (ECM) components. Specifically, 47 genes with HC LoF variants were exclusively or predominantly identified in cases, while nine genes showed such variants in the probands. Over half of unrelated cases (n = 42) and approximately one-third of probands (n = 12) were found to carry one or two LoF variants in these prioritized genes. These results highlight the role of the matrisome in the pathogenesis of Ebstein's anomaly, contributing to a better understanding of the genetic architecture underlying this condition. Our findings hold the potential to impact the genetic diagnosis and treatment approaches for Ebstein's anomaly.

Abstract
INTRODUCTION In bipolar women who took lithium during pregnancy, several epidemiology studies have reported small increases in a rare fetal cardiac defect termed Ebstein's anomaly. METHODS Behavioral, environmental, and lifestyle-associated risk factors associated with bipolar disorder and health insurance status were determined from an Internet search. The search was conducted from October 1, 2023, through October 14, 2023. The search terms employed included the following: bipolar, bipolar disorder, mood disorders, pregnancy, congenital heart defects, Ebstein's anomaly, diabetes, hypertension, Medicaid, Medicaid patients, alcohol use, cigarette smoking, marijuana, cocaine, methamphetamine, narcotics, nutrition, diet, obesity, body mass index, environment, environmental exposures, poverty, socioeconomic status, divorce, unemployment, and income. No quotes, special fields, truncations, etc., were used in the searches. No filters of any kind were used in the searches. RESULTS Women who remain on lithium in the United States throughout their pregnancy are likely to be experiencing mania symptoms and/or suicidal ideation refractory to other drugs. Pregnant women administered the highest doses of lithium salts would be expected to have been insufficiently responsive to lower doses. Any small increases in the retrospectively determined risk of fetal cardiac anomalies in bipolar women taking lithium salts cannot be disentangled from potential developmental effects resulting from very high rates of cigarette smoking, poor diet, alcohol abuse, ingestion of illegal drugs like cocaine or opioids, marijuana smoking, obesity, and poverty. CONCLUSIONS The small risks in fetal cardiac abnormalities reported in the epidemiology literature do not establish a causal association for lithium salts and Ebstein's anomaly.

Abstract
Ebstein anomaly (EA) is a rare, congenital cardiac defect of the tricuspid valve with a birth prevalence between 0.5 and 1 in 20,000 [1]. It is characterized by displacement of the tricuspid valve toward the apex of the right ventricle (RV) and "atrialization" of the RV (Fig. 57.1) [2]. EA accounts for about 0.5% of all congenital heart diseases (CHD) [2]. Depending on severity of the defect and due to heterogeneity of the disease, patient's presentation varies from severe heart failure symptoms and arrhythmia in neonatal life to asymptomatic adults.

Abstract
A circular shunt is a poor prognostic factor associated with Ebstein's anomaly. Targeting the constriction of the ductus arteriosus (DA) in order to limit or resolve the circular shunt, has been shown to improve fetal outcomes. Prenatal non-steroidal anti-inflammatory drugs (NSAIDs) have been known to constrict the DA. Recently, prenatal NSAIDs have been used for that purpose in the treatment of circular shunt. Limited research shows that it may be an effective treatment leading to improved fetal outcomes. In this article, we did an extensive review of literature to describe this therapy's effectiveness and outcomes. 82% of fetuses were able to achieve ductal constriction with prenatal NSAID therapy. For fetuses who achieved ductal constriction, fetal demise was less likely (6%) when compared to those who were unable to achieve the same (50%). Of all the fetuses with hydrops, 50% had resoluation of hydrops with prenatal NSAID treatment.

Effect of concomitant atrial septal defect on left ventricular function in adult patients with unrepaired Ebstein's anomaly: a cardiovascular magnetic resonance imaging study. J Cardiovasc Magn Reson 2023; 25:75. [PMID: 38057914 PMCID: PMC10702047 DOI: 10.1186/s12968-023-00976-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 11/10/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND Due to the heterogeneity of anatomic anomalies in Ebstein's anomaly (EA), particularly in the subset of patients with atrial septal defect (ASD), hemodynamic changes, which ultimately cause left ventricular (LV) deterioration remain unclear. The current study aimed to investigate the effect of concomitant ASD on LV function using cardiovascular magnetic resonance (CMR) imaging in patients with EA. METHODS This study included 31 EA patients with ASD, 76 EA patients without ASD, 35 patients with simple ASD and 40 healthy controls. Left/right ventricular (RV, the RV was defined as a summation of the functional RV and atrialized RV in EA patients) volumes and functional parameters, LV strain parameters, and echocardiogram indices were compared among the four groups. Associations between variables were evaluated via Spearman or Pearson correlation analyses. The association between risk factors and LV ejection fraction (EF) was determined via multivariate linear regression analysis. RESULTS Both EA patients and ASD patients had a higher RV/LV end-diastolic volume (RVEDV/LVEDV) as well as lower LV and RV ejection fractions (LVEF/RVEF) compared to healthy controls (all p < 0.05). Moreover, the EA patients with ASD had a significantly higher RVEDV/LVEDV and a lower LVEF and RVEF than those without ASD (all p < 0.05). Multivariate linear regression analysis revealed that the presence of ASD was independently associated with LVEF (β = - 0.337, p < 0.001). The RVEDV/LVEDV index was associated with LVEF (r = - 0.361, p < 0.001). Furthermore, the LV longitudinal peak diastolic strain rate (PDSR) was lower in EA patients with ASD than those without ASD, patients with simple ASD, and healthy controls (p < 0.05). CONCLUSION Concomitant ASD is an important risk factor of LV dysfunction in patients with EA, and diastolic dysfunction is likely the predominate mechanism related to LV dysfunction.

Abstract
OBJECTIVE Ebstein anomaly (EA) is a cardiac malformation with highly variable presentation and severity with limited perinatal management options. We present incorporation of fetal lung measurements into a multidisciplinary evaluation for counseling and predicting postnatal outcomes in patients with severe EA. METHODS Five fetuses with severe fetal EA were reviewed. Third trimester sonographic observed/expected total lung area (O/E TLA) and lung to head ratio (O/E LHR), fetal MRI total fetal lung volume ratio (O/E-TFLV), echocardiographic cardio-thoracic ratio (CT ratio), sonographic estimated fetal weight (EFW) by Hadlock formula and presence of hydrops, were used to guide perinatal management. RESULTS Three of five had appropriate fetal growth, were delivered at term in a cardiac operative suite, and underwent immediate intervention with good neonatal outcomes. Two had severe fetal growth restriction (FGR), CT ratios > 0.8 and O/E LHR and TLA < 25%. One of which delivered prematurely with neonatal demise and one suffered in utero demise at 34 weeks. CONCLUSIONS FGR, hydrops, increased CT ratio and reduced O/E LHR and TFLV are potential prognosticators of poor outcomes in severe EA, and should be validated in larger cohorts that would allow for a statistical analysis of the predictive utility of these measurements.

Eur Heart J Case Rep 2023; 7:ytad531.

Abstract
Background Ebstein's anomaly occurs when there is an apical displacement of the tricuspid valve with septal and posterior valve leaflets tethering. This condition often occurs in association with other congenital, structural, or conduction system diseases, including intracardiac shunts, valvular lesions, arrhythmias, accessory conduction pathways, and first-degree atrioventricular (AV) block. We present for the first time a case of a patient with Ebstein's anomaly who presented with second-degree Mobitz II AV block and was successfully treated with conduction system pacing (CSP) due to her young age and the likelihood of a long-term high percentage of pacing. Case summary We present a case of a 42-year-old lady with a background of complex congenital heart disease, including severe pulmonary stenosis, Ebstein anomaly, and atrial septal defect (ASD). She required complex surgical intervention, including tricuspid valve (TV) repair and subsequently replacement, ASD closure, and pulmonary balloon valvuloplasty. She presented to our hospital with symptomatic second-degree Mobitz II AV block (dizziness, shortness of breath, and exercise intolerance) and right bundle branch block (RBBB) on her baseline ECG. Her echocardiogram showed dilated right ventricle (RV) and left ventricle (LV) with low normal LV systolic function. Due to her young age and the likelihood of a long-term high percentage of RV pacing, we opted for CSP after a detailed discussion and patient consent. The distal HIS position is the preferred pacing strategy at our centre. We could not cross the TV with the standard Medtronic C315 HIS catheter, so we had to use the deflectable C304 HIS catheter. Mapping and pacing of the distal HIS bundle were achieved by Medtronic Selectsecure 3830, 69 cm lead. HIS bundle pacing led to the correction of both second-degree Mobitz II AV block and pre-existing RBBB. The implantation was uneventful, and the patient was discharged home the next day without any acute complications. Discussion Distal HIS pacing is feasible in patients with surgically treated complex Ebstein anomaly and heart block. This approach can normalize the QRS complex with a high probability of preserving or improving LV function.

Abstract
Ebstein's anomaly is a rare congenital heart disease characterized by tricuspid valve downward displacement and is associated with additional cardiac phenotypes such as left ventricle non-compaction. The genetic basis of Ebstein's anomaly has yet to be fully elucidated, although several genes (e.g., NKX2-5, MYH7, TPM1, and FLNA) may contribute to Ebstein's anomaly. Here, in two Ebstein's anomaly families (a three-generation family and a trio), we identified independent heterozygous nonsense variants in laminin subunit 3 α (LAMA3), cosegregated with phenotypes in families with reduced penetrance. Furthermore, knocking out Lama3 in mice revealed that haploinsufficiency of Lama3 led to Ebstein's malformation of the tricuspid valve and an abnormal basement membrane structure. In conclusion, we identified a novel gene-disease association of LAMA3 implicated in Ebstein's anomaly, and the findings extended our understanding of the role of the extracellular matrix in Ebstein's anomaly etiology.

Abstract
Postoperative stenosis or regurgitation of the tricuspid valve is common and affects the prognosis after repair surgery of Ebstein's anomaly. However, it is unclear how intraoperative echocardiography influences the postoperative course. We report a longitudinal echocardiography course including intraoperative transesophageal echocardiography in a cone reconstruction procedure for Ebstein's anomaly in a 17-year-old woman. Tight tricuspid valvuloplasty was preferred, but the tricuspid annulus enlarged rather after surgery. The evaluation of the tricuspid valve form and function using intraoperative echocardiography could support the surgeon's impression.

Abstract
OBJECTIVE Ebstein's anomaly is a rare congenital cardiac condition and data regarding pregnancy outcomes in this patient group are scarce. We evaluated the maternal and perinatal risks of pregnancy in 81 women with Ebstein's anomaly. METHODS The Registry of Pregnancy and Cardiac disease is a prospective global registry of pregnancies in women with structural cardiac disease. Pregnancy outcomes in women with Ebstein's anomaly were examined. The primary outcome was the occurrence of a major adverse cardiac event (MACE) defined as maternal mortality, heart failure, arrhythmia, thromboembolic event or endocarditis. Secondary endpoints were obstetric and perinatal outcomes and the influence of pregnancy on tricuspid valve regurgitation as well as right atrial and ventricular dimensions. RESULTS In the 81 women with Ebstein's anomaly (mean age 29.7±6.1 years, 46.9% nulliparous), MACE occurred in 8 (9.9%) pregnancies, mostly heart failure (n=6). There were no maternal deaths. Prepregnancy signs of heart failure were predictive for MACE. Almost half of the women were delivered by caesarean section (45.7%) and preterm delivery occurred in 24.7%. Neonatal mortality was 2.5% and 4.9% of the infants had congenital heart disease. In the subgroup in which prepregnancy and postpregnancy data were available, there was no difference in tricuspid valve regurgitation grade or right atrial and ventricular dimensions before and after pregnancy. CONCLUSIONS Most women with Ebstein's anomaly tolerate pregnancy well, but women with prepregnancy signs of heart failure are at higher risk for MACE during pregnancy and should be counselled accordingly.

Abstract
OBJECTIVE To review and perform a meta-analysis of observational studies that examined associations between prenatal cannabis exposure and major structural birth defects. DATA SOURCES Information sources included Google Scholar, BIOSIS, PubMed/MEDLINE, EMBASE CINAHL, and ClinicalTrials.gov. METHODS OF STUDY SELECTION Study titles and abstracts were reviewed with Abstrackr software. We included observational studies that examined the risk of major structural birth defects in people who used cannabis during pregnancy compared with those who had not used cannabis. We excluded case reports, ecologic studies, conference abstracts, manuscript preprints, studies designed to examine effects of cannabis used concurrently with other drugs, and studies that included synthetic cannabinoids. This process yielded 23 studies that analyzed data from birth years 1968-2021. TABULATION, INTEGRATION, AND RESULTS We clustered and meta-analyzed measures of association for birth defects by anatomic group. Eleven articles reported an association between cannabis use and the risk of a nonspecific outcome (eg, congenital anomaly). We estimated a pooled odds ratio of 1.33 (95% CI 1.14-1.56) and a pooled adjusted odds ratio (aOR) of 1.22 (95% CI 1.00-1.50). Anatomic groups examined were cardiac (nine studies), oral cleft (three studies), digestive (four studies), genitourinary (three studies), musculoskeletal (seven studies), and nervous system (five studies). Across most outcomes, we reported positive pooled unadjusted associations that were usually attenuated after the inclusion of only adjusted estimates. Two specific anomalies, with limited data, had pooled effect estimates that did not attenuate to the null after adjustment: Ebstein anomaly (two studies, aOR 2.19, 95% CI 1.25-3.82) and gastroschisis (five studies, aOR 2.50, 95% CI 1.09-5.740). CONCLUSION Studies examining associations between prenatal exposure to cannabis and major structural birth defects were heterogeneous. Most published effect estimates were unadjusted and scored low on our risk-of-bias assessment. Overall, we found inconsistent evidence to suggest that prenatal cannabis exposure is associated with birth defects. However, findings related to specific anomalies should be considered in further research. SYSTEMATIC REVIEW REGISTRATION PROSPERO, CRD42022319041.

Abstract
The great majority of patients born with congenital heart disease (CHD) are living well into adulthood, yet they often have residual hemodynamic lesions, including valvar regurgitation. As these complex patients grow older, they are at risk of developing heart failure, which can be exacerbated by the underlying valvular regurgitation. In this review, we describe the etiologies of heart failure related to valvular regurgitation in the CHD population and discuss potential interventions.

Abstract
Patients with two congenital heart diseases (CHDs), Ebstein's anomaly (EA) and left ventricular noncompaction (LVNC), suffer higher morbidity than either CHD alone. The genetic etiology and pathogenesis of combined EA/LVNC remain largely unknown. We investigated a familial EA/LVNC case associated with a variant (p.R237C) in the gene encoding Kelch-like protein 26 (KLHL26) by differentiating induced pluripotent stem cells (iPSCs) generated from affected and unaffected family members into cardiomyocytes (iPSC-CMs) and assessing iPSC-CM morphology, function, gene expression, and protein abundance. Compared with unaffected iPSC-CMs, CMs containing the KLHL26 (p.R237C) variant exhibited aberrant morphology including distended endo(sarco)plasmic reticulum (ER/SR) and dysmorphic mitochondria and aberrant function that included decreased contractions per minute, altered calcium transients, and increased proliferation. Pathway enrichment analyses based on RNASeq data indicated that the "structural constituent of muscle" pathway was suppressed, whereas the "ER lumen" pathway was activated. Taken together, these findings suggest that iPSC-CMs containing this KLHL26 (p.R237C) variant develop dysregulated ER/SR, calcium signaling, contractility, and proliferation.NEW & NOTEWORTHY We demonstrate here that iPSCs derived from patients with Ebstein's anomaly and left ventricular noncompaction, when differentiated into cardiomyocytes, display significant structural and functional changes that offer insight into disease pathogenesis, including altered ER/SR and mitochondrial morphology, contractility, and calcium signaling.

Comparative outcomes and risk analysis after cone repair or tricuspid valve replacement for Ebstein's anomaly. JTCVS OPEN 2023; 14:372-384. [PMID: 37425446 PMCID: PMC10328840 DOI: 10.1016/j.xjon.2023.03.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 02/26/2023] [Accepted: 03/02/2023] [Indexed: 07/11/2023]
Abstract
Objective Ebstein's anomaly is a rare congenital heart malformation for which surgical and medical management are still controversial. The cone repair has transformed surgical outcomes in many of these patients. We aimed to present our results on the outcomes of patients with Ebstein's anomaly who underwent a cone repair or tricuspid valve replacement. Methods A total of 85 patients who underwent a cone repair (mean age, 16.5 years) or tricuspid valve replacement (mean age, 40.8 years) between 2006 and 2021 were included. Univariate, multivariate, and Kaplan-Meier analyses were used to evaluate operative and long-term outcomes. Results Residual/recurrent greater than mild-to-moderate tricuspid regurgitation at discharge was higher after cone repair compared with tricuspid valve replacement (36% vs 5%; P = .010). However, at last follow-up, the risk of greater than mild-to-moderate tricuspid regurgitation was not different between groups (35% in the cone group vs 37% in the tricuspid valve replacement group; P = .786). The tricuspid valve replacement group had a higher risk of tricuspid valve reoperation (37% vs 9%; P = .005) and tricuspid stenosis (21% vs 0%; P = .002) compared with the cone repair group. Kaplan-Meier freedom from reintervention was 97%, 91%, and 91% at 2, 4, and 6 years after cone repair, respectively, and 84%, 74%, and 68% at 2, 4, and 6 years after tricuspid valve replacement, respectively (P = .0191). At last follow-up, right ventricular function was significantly worse from baseline in the tricuspid valve replacement group (P = .0294). There were no statistical differences between age-stratified cohorts or surgeon volume in the cone repair group. Conclusions The cone procedure offers excellent results, with stable tricuspid valve function and low reintervention and death rates at last follow-up. The rate of greater than mild-to-moderate residual tricuspid regurgitation at discharge was higher after cone repair compared with tricuspid valve replacement, but this did not expose the patient to a higher risk of reoperation or death at last follow-up. Tricuspid valve replacement was associated with a significantly higher risk of tricuspid valve reoperation and tricuspid valve stenosis, and worse right ventricular function at last follow-up.

Abstract
Tricuspid valve (TV) disease is highly prevalent in the general population. For ages considered "the forgotten valve" because of the predominant interest in left-side valve disease, the TV has now received significant attention in recent years, with significant improvement both in diagnosis and in management of tricuspid disease. TV is characterized by complex anatomy, physiology, and pathophysiology, in which the right ventricle plays a fundamental role. Comprehensive knowledge of molecular and cellular mechanisms underlying TV development, TV disease, and tricuspid regurgitation-related right-ventricle cardiomyopathy is necessary to enhance TV disease understanding to improve the ability to risk stratify TR patients, while also predicting valve dysfunction and/or response to tricuspid regurgitation treatment. Scientific efforts are still needed to eventually decipher the complete picture describing the etiopathogenesis of TV and TV-associated cardiomyopathy, and future advances to this aim may be achieved by combining emerging diagnostic imaging modalities with molecular and cellular studies. Overall, basic science studies could help to streamline a new coherent hypothesis underlying both the development of TV during embryogenesis and TV-associated disease and its complications in adult life, providing the conceptual basis for the ultimate and innovative field of valve repair and regeneration using tissue-engineered heart valves.

Abstract
Background Ebstein's anomaly is a rare condition due to incomplete delamination of the tricuspid valve (TV) leaflets with downward displacement of the proximal leaflet attachments. It is associated with a smaller functional right ventricle (RV) and tricuspid regurgitation (TR) that is typically treated with TV replacement or repair. However, future re-intervention poses challenges. We describe a multidisciplinary team approach to re-intervention in a pacing-dependant Ebstein patient with severe bioprosthetic TV regurgitation. Case summary A 49-year-old female patient underwent bioprosthetic TV replacement for severe TR in Ebstein's. Post-operatively, she developed complete atrioventricular (AV) block necessitating the implantation of a permanent pacemaker which included a coronary sinus (CS) lead as the ventricular lead. Five years later, she presented with syncope due to a failing ventricular pacing lead, and a new RV lead was positioned across the TV bioprosthesis due to the lack of CS options. Two years later, she presented with breathlessness and lethargy with severe TR identified on transthoracic echocardiography. She successfully underwent a percutaneous leadless pacemaker implant, extraction of existing pacing system, and implantation of valve-in-valve TV. Discussion Patients with Ebstein's anomaly typically undergo TV repair or replacement. Following surgical intervention, owing to the anatomical location, patients can develop AV block requiring a pacemaker. Pacemaker implantation may involve a CS lead to avoid placing a lead across the new TV in efforts to avoid lead induced TR. Over time, these patients not uncommonly require re-intervention that can be challenging especially in pacing-dependant patients with leads across the TV.

Abstract
Congenital Mullerian anomalies are rare developmental defects that result in malformation of the fallopian tubes, uterus, cervix, and vagina. The bicornuate uterus is one of the many variants of Mullerian anomalies, defined as having an external fundal indentation of greater than one centimeter. Pelvic ultrasound has a sensitivity of 99% for identifying bicornuate uteruses and is the predominant imaging device used for diagnosis. The cervical and uterine cavity anatomy in patients with a bicornuate uterus varies. The effect of maternal uterine structure on offspring development has been poorly documented. This report details a rare case of dichorionic-diamniotic twin pregnancy in a bicornuate uterus with one fetus affected by Ebstein's anomaly. Twin A was diagnosed by first-trimester ultrasound with right renal agenesis and Ebstein's anomaly. Twin B did not have any anatomical defects identified on ultrasound. Both twins were delivered via emergency repeat cesarean section at 34 weeks and four days due to nonreassuring fetal heart tracings and twin A in the breech presentation. Twin A and twin B were found to be in separate horns within the uterus during low transverse cesarean section. Twin A required endotracheal intubation in the delivery room due to respiratory distress. Both twins required neonatal intensive care treatment. Twin A was found to have a right pelvic kidney, rather than right renal agenesis, while in the neonatal intensive care unit. Females with germline mutations in the Mullerian duct and urogenital sinus development have resulted in concomitant malformations in the uterus and kidneys. This is a rare case of an infant with a cardiac anomaly born to a mother with a germline mutation. The relationship between congenital heart defects and uterine anomalies has not been identified. As seen in this case, maternal malformations impacting fetal cardiac development can be sporadic or result from germline mutations in mesoderm that have not been reported yet.

Abstract
We describe a rare case of Ebstein's anomaly (EA) combined with left ventricular outflow tract obstruction in a 54-year-old man that was accurately identified by echocardiography, cardiac magnetic resonance imaging (CMR). The imaging result was ultimately validated by surgery. We emphasize the clinical importance of using echocardiography and CMR together to provide a thorough, noninvasive explanation of these results.

Cardiac remodeling after tricuspid valve repair in Ebstein's anomaly: a magnetic resonance study. Eur Radiol 2023; 33:2052-2061.

Abstract
OBJECTIVES We aimed to evaluate immediate and midterm cardiac remodeling after surgery by cardiac magnetic resonance (CMR) in Ebstein's anomaly (EA), and also to investigate preoperative predictors of right ventricular (RV) normalization. METHODS We retrospectively analyzed CMR parameters of the whole heart in adult patients with EA before surgery, at discharge and follow-up. RESULTS A total of 26 patients were included and performed CMR at 7 days (interquartile range, 3-13 days) before surgery. Immediate postoperative CMR was finished at discharge (median: 8 [7-9] days; n = 18) and follow-up CMR at 187 days (interquartile range, 167-356 days; n = 17). RV and right atrial (RA) volumes promptly decreased immediately after surgery and at follow-up (all p < 0.05). RV ejection fraction decreased significantly at discharge (p < 0.05) but recovered at follow-up (p = 0.18). However, RV global longitudinal strain and RA reservoir strain were significantly impaired immediately and midterm after surgery (all p < 0.05). Indexed left ventricular (LV) end-diastolic volume, stroke volume, as well as global longitudinal strain increased from preoperative to follow-up (all p < 0.05). Patients who achieved normalization of RV volumes after surgery had smaller severity index and RV and RA volumes and higher LV ejection fraction and RA reservoir strain at baseline than patients without RV normalization (all p < 0.05). CONCLUSIONS Reverse biventricular remodeling took place in EA after tricuspid valve surgery. Tricuspid valve reconstruction should be performed before deterioration of RV volume overload and LV function to achieve reverse RV remodeling. Key Points • After removing the volume load of tricuspid regurgitation in Ebstein's anomaly, reverse remodeling was detected by CMR in both left and right heart at midterm follow-up. • Tricuspid valve reconstruction should be performed before deterioration of RV volume overload and LV function to achieve reverse RV remodeling.

Abstract
Ebstein's anomaly is a congenital heart defect characterized by the displacement of the tricuspid valve, and its leaflets to be malformed. Due to the defect involving the tricuspid valve, there is a reverse flow of blood into the right-sided atrium, which may lead to cardiac hypertrophy and edema of the lower extremities. There is a decreased flow of blood out of the right heart due to reduced right ventricular contractility and tricuspid regurgitation. Children afflicted with this anomaly usually suffer from atrial septal defect and this is usually diagnosed before birth on a routine ultrasound scan. In neonates, cyanosis can be seen due to right-to-left atrial shunting or as a result of severe congestive heart failure. If the infant has pulmonary hypertension, cyanosis is markedly increased as there will be a limitation in pulmonary blood flow. In adults, arrhythmias, cyanosis, and heart failure are seen. The bundle of Kent leads to the formation of an electrical conduction abnormality between the right ventricle and atrium. This leads to a condition commonly known as Wolff- Parkinson-White syndrome in patients. An enlarged spherical heart is usually present on a chest X-ray. ECG changes of Ebstein's anomaly show taller than usual P waves, PR prolongation, and right bundle branch block. There can be certain neurological and extracardiac manifestations too such as hemiplegia, stroke, dysarthria, etc. During fetal life, specifically at 16 and 20 weeks of gestation, the anomaly can be diagnosed via echocardiography. Prostaglandin infusion (PGE1) is given to maintain pulmonary circulation in neonates if cyanosis is seen. In children and adults with congestive cardiac failure due to this anomaly, medical management includes digoxin, beta-blockers, diuretics, and angiotensin converting enzyme (ACE) inhibitors to improve heart failure. Surgical treatment includes valve reconstruction. In this article, we review the pathophysiology, genetics, diagnosis, management, and prognosis of Ebstein's Anomaly along with a comprehensive discussion on its genetics, neurological manifestations, extracardiac features, and current advancements in treatment.

Abstract
BACKGROUND Prolonged mechanical ventilation (PMV) after pediatric cardiac surgery imposes a great burden on patients in terms of morbidity, mortality as well as financial costs. Ebstein anomaly (EA) is a rare congenital heart disease, and few studies have been conducted about PMV in this condition. This study aimed to establish a simple-to-use nomogram to predict the risk of PMV for EA children. METHODS The retrospective study included patients under 18 years who underwent corrective surgeries for EA from January 2009 to November 2021. PMV was defined as postoperative mechanical ventilation time longer than 24 hours. Through multivariable logistic regression, we identified and integrated the risk factors to develop a simple-to-use nomogram of PMV for EA children and internally validated it by bootstrapping. The calibration and discriminative ability of the nomogram were determined by calibration curve, Hosmer-Lemeshow goodness-of-fit test and receiver operating characteristic (ROC) curve. RESULTS Two hundred seventeen children were included in our study of which 44 (20.3%) were in the PMV group. After multivariable regression, we obtained five risk factors of PMV. The odds ratios and 95% confidence intervals (CI) were as follows: preoperative blood oxygen saturation, 0.876(0.805,0.953); cardiothoracic ratio, 3.007(1.107,8.169); Carpentier type, 4.644(2.065,10.445); cardiopulmonary bypass time, 1.014(1.005,1.023) and postoperative central venous pressure, 1.166(1.016,1.339). We integrated the five risk factors into a nomogram to predict the risk of PMV. The area under ROC curve of nomogram was 0.805 (95% CI, 0.725,0.885) and it also provided a good discriminative information with the corresponding Hosmer-Lemeshow p values > 0.05. CONCLUSIONS We developed a nomogram by integrating five independent risk factors. The nomogram is a practical tool to early identify children at high-risk for PMV after EA corrective surgery.

Abstract
Conventionally, scuba diving has been discouraged for adult patients with congenital heart disease (ACHD). This restrictive sports advice is based on expert opinion in the absence of high-quality diving-specific studies. However, as survival and quality of life in congenital heart disease (CHD) patients have dramatically improved in the last decades, a critical appraisal whether such restrictive sports advice is still applicable is warranted. In this review, the cardiovascular effects of diving are described and a framework for the work-up for ACHD patients wishing to engage in scuba diving is provided. In addition, diving recommendations for specific CHD diagnostic groups are proposed.

Abstract
Ebstein's anomaly is a congenital deformity marked by disease of the tricuspid valve and right cardiac hypertrophy. The severity, morphology, and appearance of Ebstein's anomaly cases might vary greatly. We discuss a case of an eight-year-old child with Ebstein's anomaly who presented with supraventricular tachycardia and was effectively treated with amiodarone after initial treatment with adenosine failed to reduce the heart rate.

Abstract
We report a patient with Ebstein's anomaly, on chronic milrinone therapy for right ventricular failure, who underwent palliative percutaneous closure of her atrial septal defect (ASD) due to recurring strokes. Repeated evaluation of right-sided pressures was performed prior to ASD closure to determine if our patient could tolerate the intervention. Definitive ASD closure was performed under fluoroscopic and transesophageal echocardiogram guidance.

Abstract
Ebstein's anomaly is an uncommon congenital disorder affecting the tricuspid valve. We herein report a 38-year-old woman who experienced consciousness and sensory disturbance during treatment for heart failure caused by Ebstein's anomaly. Urgent magnetic resonance imaging and cerebral angiography demonstrated acute cerebral infarction and internal carotid artery obstruction with the development of collateral arteries. We diagnosed her with multiple cerebral infarctions due to moyamoya disease. Ebstein's anomaly concomitant with moyamoya disease is extremely rare. However, we should consider the possibility of this rare but important concurrence when treating patients with heart failure due to Ebstein's anomaly to avoid excessive diuresis and vasodilation and irreversible brain injury.

Abstract
Introduction and importance: Ebstein's anomaly (EA) is a rare congenital heart disease characterized by apical displacement of the tricuspid valve associated with atrialization of the right ventricle. Most of the cases are diagnosed in childhood but asymptomatic cases may remain undiagnosed and survive until old age. Case presentation We present a rare case of Ebstein's Anomaly with pericardial effusion which was diagnosed for the first time in her mid-fifties when she developed atrial fibrillation and right heart failure with severe tricuspid regurgitation, which was managed medically. Clinical discussion The patient with Ebstein's anomaly can be found even at an older age with variable presentation and the association with pericardial effusion although very rare can present in such patients. Conclusion Ebstein's anomaly despite being a rare congenital condition can present clinically even beyond the age of fifty without any previous diagnosis and surgical intervention for the condition. It usually presents with features of heart failure and arrhythmia but can also have a rare association like pericardial effusion.

Abstract
Ebstein's anomaly is a rare congenital heart disease. We present the case of a 47-year-old woman with history of Ebstein's anomaly who was referred to nuclear medicine department for a myocardial perfusion single-photon emission computed tomography (SPECT) imaging during pre-anesthetic check-up. Myocardial SPECT perfusion images with (99mTc)-Sestamibi demonstrated medium sizes fixed perfusion defect in the mid and proximal infero-septal wall adjacent inferior wall. This is a cause of potential misinterpretation on myocardial SPECT perfusion imaging as this perfusion defect was due to fibrosis rather than scarred myocardium.

Ebstein's Anomaly: From Fetus to Adult-Literature Review and Pathway for Patient Care. Pediatr Cardiol 2022; 43:1409-1428.

Abstract
Ebstein's anomaly, first described in 1866 by Dr William Ebstein, accounts for 0.3-0.5% of congenital heart defects and represents 40% of congenital tricuspid valve abnormalities. Ebstein's anomaly affects the development of the tricuspid valve with widely varying morphology and, therefore, clinical presentation. Associated congenital cardiac lesions tend to be found more often in younger patients and may even be the reason for presentation. Presentation can vary from the most extreme form in fetal life, to asymptomatic diagnosis late in adult life. The most symptomatic patients need intensive care support in the neonatal period. This article summarizes and analyzes the literature on Ebstein's anomaly and provides a framework for the investigation, management, and follow-up of these patients, whether they present via fetal detection or late in adult life. For each age group, the clinical presentation, required diagnostic investigations, natural history, and management are described. The surgical options available for patients with Ebstein's anomaly are detailed and analyzed, starting from the initial mono-leaflet repairs to the most recent cone repair and its modifications. The review also assesses the effects of pregnancy on the Ebstein's circulation, and vice versa, the effects of Ebstein's on pregnancy outcomes. Finally, two attached appendices are provided for a structured echocardiogram protocol and key information useful for comprehensive Multi-Disciplinary Team discussion.

Abstract
The macroreentrant atrial tachycardia is very frequent in the adults with congenital heart disease. The impact of the arrhythmias on this type of patients is related to several factors: the anatomy and physiopathology of the specific congenital heart disease (CHD), the sequelae of the corrective surgery or surgical palliation, the presence of residual lesions (shunt, regurgitation), and the age and the clinical status of the patient and the comorbidities. In turn, the mechanism of the MAT depends on the peculiar features of the conduction's system in the CHD and native and acquired (post-surgery) substrates.
