Abstract
Congenital eyelid imbrication syndrome is a rare eyelid finding where a long upper lid overlaps the lower lid when the eyes are closed. To date, congenital eyelid imbrication syndrome has been described in the literature less than 10 times. We present a case of congenital eyelid imbrication syndrome in a patient with trisomy 21 and tetralogy of Fallot on a prostaglandin E infusion to maintain a patent ductus arteriosus prior to definitive heart surgery. While on the infusion, the patient developed peripheral edema and flushing due to vasodilation. This coincided with eyelid swelling, conjunctival chemosis, and eversion of the eyelids. Upon cessation of the prostaglandin E1 infusion, his eyelid eversion resolved.

Abstract
OBJECTIVE Machine learning (ML) can facilitate prediction of major adverse cardiovascular events (MACEs) in repaired tetralogy of Fallot (rTOF). We sought to determine the incremental value of ML above expert clinical judgement for risk prediction in rTOF. METHODS Adult congenital heart disease (ACHD) clinicians (≥10 years of experience) participated (one cardiac surgeon and four cardiologists (two paediatric and two adult cardiology trained) with expertise in heart failure (HF), electrophysiology, imaging and intervention). Clinicians identified 10 high-yield variables for 5-year MACE prediction (defined as a composite of mortality, resuscitated sudden death, sustained ventricular tachycardia and HF). Risk for MACE (low, moderate or high) was assigned by clinicians blinded to outcome for adults with rTOF identified from an institutional database (n=25 patient reviews conducted by five independent observers). A validated ML model identified 10 variables for risk prediction in the same population. RESULTS Prediction by ML was similar to the aggregate score of all experts (area under the curve (AUC) 0.85 (95% CI 0.58 to 0.96) vs 0.92 (0.72 to 0.98), p=0.315). Experts with ≥20 years of experience had superior discriminative capacity compared with <20 years (AUC 0.98 (95% CI 0.86 to 0.99) vs 0.80 (0.56 to 0.93), p=0.027). In those with <20 years of experience, ML provided incremental value such that the combined (clinical+ML) AUC approached ≥20 years (AUC 0.85 (95% CI 0.61 to 0.95), p=0.055). CONCLUSIONS Robust prediction of 5-year MACE in rTOF was achieved using either ML or a multidisciplinary team of ACHD experts. Risk prediction of some clinicians was enhanced by incorporation of ML suggesting that there may be incremental value for ML in select circumstances.

Abstract
We sought to estimate the median post-operative length of stay (PLOS) and predictors of PLOS following tetralogy of Fallot (ToF) repair at a specialist surgical center in the North of England. The local National Congenital Heart Disease Audit dataset was used to identify patients aged < 2 years who underwent surgical repair for ToF between 1 January 1986 and 13 May 2022. Coefficients representing the median change in PLOS (days) according to predictors were estimated using Quantile regression. There were 224 patients (59.4% male, median age = 9 months, interquartile range (IQR) 5-13 months) with a median PLOS of 9 days (IQR 7-13). In the univariable regression, age (months) and weight (kg) at operation (β = - 0.17, 95% CI: - 0.33, - 0.01) and (β = - 0.53, 95% CI: - 0.97, - 0.10), previous (cardiac or thoracic) procedure (β = 5, 95% CI:2.38, 7.62), procedure urgency (elective vs urgent) (β = 2.8, 95% CI:0.39, 5.21), bypass time (mins) (β = 0.03, 95% CI:0.01, 0.05), cross-clamp time (mins) (β = 0.03, 95% CI:0.01, 0.06) and duration of post-operative intubation (days) (β = 0.81, 95% CI:0.67, 0.96), were significantly associated with PLOS. Previous procedure and intubation time remained significant in multivariable analyses. Some patient and operative factors can predict PLOS following complete ToF repair. Information on PLOS is important for health professionals to support parents in preparing for their child's discharge and to make any necessary practical arrangements. Health commissioners can draw on evidence-based guidance for resource planning. The small sample size may have reduced the power to detect small effect sizes, but this regional study serves as a foundation for a larger national study.

Abstract
We report a case of a 44-year-old woman surgically treated for tetralogy of Fallot who experienced an acute and extensive Stanford A type aortic dissection despite the meticulous follow-up. While aortic dilatation is prevalent in individuals with repaired tetralogy of Fallot, aortic dissection represents a rare consequence, that when it appears, is progressive and usually detected during the check-up visits. In the case reported, the dissection was unexpected and severe, and the patient's clinical state worsened suddenly, leading to death after a few days. Constant awareness for aortic aneurysms is essential in the Fallot tetralogy population, nevertheless, several causes may contribute to the acute worsening of the clinical condition until the patient's death.

Abstract
BACKGROUND Patients with repaired tetralogy of Fallot (TOF) are at risk for ventricular tachycardia (VT) related to well-described anatomical isthmuses. OBJECTIVE The purpose of this study was to explore QRS morphology as an indicator of anatomical isthmus conduction. METHODS Patients with repaired TOF and complete right bundle branch block referred for transcatheter pulmonary valve replacement (PVR) or presenting with sustained VT underwent comprehensive 3-dimensional mapping in sinus rhythm. Electrocardiographic characteristics were compared to right ventricular (RV) activation and anatomical isthmus conduction properties. RESULTS Twenty-two patients (19 pre-pulmonary valve replacement and 3 clinical VT) underwent comprehensive 3-dimensional mapping (median 39 years; interquartile range [IQR] 27-48 years; 12 [55%] male). Septal RV activation (median 40 ms; IQR 34-46 ms) corresponded to the nadir in lead V1 and free wall activation (median 71 ms; IQR 64-81 ms) to the transition point in the upstroke of the R' wave. Patients with isthmus block between the pulmonary annulus and the ventricular septal defect patch and between the ventricular septal defect patch and the tricuspid annulus (when present), were more likely to demonstrate lower amplitude R' waves in lead V1 (5.8 mV vs 9.4 mV; P = .005), QRS fragmentation in lead V1 (15 [94%] vs 2 [13%]; P < .001), and terminal S waves in lead aVF (15 [94%] vs 6 [40%]; P < .001) than those with intact conduction. During catheter ablation, these QRS changes developed during isthmus block. CONCLUSION For patients with repaired TOF, the status of septal isthmus conduction was evident from sinus rhythm QRS morphology. Low-amplitude, fragmented R' waves in lead V1 and terminal S waves in the inferior leads were related to septal isthmus conduction abnormalities, providing a mechanistic link between RV activation and common electrocardiographic findings.

Abstract
OBJECTIVE The purpose of this study was to compare pulmonary arterial (PA) growth and morbidity, mortality, reintervention and complete repair rates after modified transannular patching palliation (mTAP) versus modified Blalock-Taussig-Thomas shunt (mBTS) for palliation in infants with severe tetralogy of Fallot (TOF) with diminutive pulmonary arteries. METHODS This was a retrospective case review study of 107 patients (64 males) with severe TOF who underwent staged repair with either mTAP (n = 55) or mBTS (n = 52) over an 8-year period. Procedure-related PA growth and morbidity, mortality, reintervention and complete repair rates were compared. RESULTS Two deaths occurred in the mBTS group due to sudden cardiac arrest, and five patients needed reintervention after the mBTS procedure because of shunt thrombosis or stenosis. Postoperative complications of mBTS included sudden cardiac arrest, shunt thrombosis/stenosis, vocal cord palsy and diaphragmatic palsy. Unlike in the mBTS group, no death, severe complications or reintervention occurred in the mTAP group. Oxygen saturations post mTAP and mBTS were significantly higher, which improved from 67.73 ± 4.36% to 94.33 ± 2.19% in the mTAP group and from 68.24 ± 3.87% to 86.87 ± 3.38% in the mBTS group. The increase in oxygen saturation and pulmonary artery growth (from pre- to post palliation) was significantly better with mTAP than with mBTS palliation (p < 0.01). All 55 patients showed complete repair after mTAP, and the time from palliation to complete repair was significantly shorter in the mTAP group. CONCLUSIONS In a severe form of TOF with the hypoplastic PA tree, mTAP seems to be a better strategy that is safe and better facilitates satisfactory pulmonary arterial growth until complete repair than the mBTS procedure.

Abstract
Pediatric and neonatal critical care providers involved in transport run calls involving patients diagnosed with Tetralogy of Fallot, which can occasionally be a challenge for some providers. Making up around 10% of all congenital heart defects, inevitably makes Tetralogy of Fallot (TOF) the most common of all the cyanotic congenital heart diseases. There are some transport teams that do not have the capability and invasive equipment that a referring hospital may have to manage these high acuity low volume patients. This makes it imperative to have a good working knowledge of this condition, and more importantly, the ability to recognize it when encountered so that you will then be able treat these patients.

Abstract
BACKGROUND Tetralogy of Fallot (TOF) is a common congenital heart disease with high mortality. However, the medical imageology and liquidbiopsy techniques present certain limitations. Thus, this study investigated the plasma metabolic profiles to distinguish key metabolites for early diagnosis of TOF. METHODS In total, 69 patients with TOF and 43 normal controls were enrolled for targeted metabolomics based on liquid chromatography-tandem mass spectroscopy (LC-MS/MS). Absolute quantification of metabolites was performed using our standard database. The differentially expressed metabolites (DEMs) were screened by fold change (FC), VIP value and pearson correlation coefficient of OPLS-DA model. Receiver operating characteristic curve (ROC) was used to evaluate predictive ability of DEMs. RESULTS Different metabolic profiles were presented between TOF and Normal.The pathway analysis showed that significantly changed metabolites were enriched in nicotinamide and purine metabolism. Many intermediatesproductof purine and amido acid were higher in TOF than in Normal group, while energy substrates and electron carriers were lower in TOF than in Normal group. ROC analysis revealed a high diagnostic value of plasma FAD for differentiating TOF from Normal (AUC = 1). CONCLUSION Our study quantitatively characterized plasma metabolites in patients with TOF and may help to develop reliable biomarkers that contribute to the early TOF screening.

Abstract
Heart failure in tetralogy of Fallot in the newborn period is rare and is usually due to either large aortopulmonary collaterals or absent pulmonary valve syndrome with severe pulmonary regurgitation. Pink tetralogy of Fallot and tetralogy of Fallot with disconnected pulmonary arteries from the aorta may present beyond the newborn period with heart failure when Pulmonary vascular resistance (PVR) falls. We describe the diagnostic and therapeutic pathway in a rare case of heart failure in newborn with tetralogy of Fallot.

Abstract
AIMS Patients with repaired tetralogy of Fallot (rTOF) have an increased risk of ventricular tachycardia (VT), with slow conducting anatomical isthmus (SCAI) 3 as dominant VT substrate. In patients with right bundle branch block (RBBB), SCAI 3 leads to local activation delay with a shift of terminal RV activation towards the lateral RV outflow tract which may be detected by terminal QRS vector changes on sinus rhythm electrocardiogram (ECG). METHODS AND RESULTS Consecutive rTOF patients aged ≥16 years with RBBB who underwent electroanatomical mapping at our institution between 2017-2022 and 2010-2016 comprised the derivation and validation cohort, respectively. Forty-six patients were included in the derivation cohort (aged 40±15 years, QRS duration 165±23 ms). Among patients with SCAI 3 (n = 31, 67%), 17 (55%) had an R″ in V1, 18 (58%) had a negative terminal QRS portion (NTP) ≥80 ms in aVF, and 12 (39%) had both ECG characteristics, compared to only 1 (7%), 1 (7%), and 0 patient without SCAI, respectively.Combining R″ in V1 and/or NTP ≥80 ms in aVF into a diagnostic algorithm resulted in a sensitivity of 74% and specificity of 87% in detecting SCAI 3. The inter-observer agreement for the diagnostic algorithm was 0.875. In the validation cohort [n = 33, 18 (55%) with SCAI 3], the diagnostic algorithm had a sensitivity of 83% and specificity of 80% for identifying SCAI 3. CONCLUSION A sinus rhythm ECG-based algorithm including R″ in V1 and/or NTP ≥80 ms in aVF can identify rTOF patients with a SCAI 3 and may contribute to non-invasive risk stratification for VT.

Abstract
Absent pulmonary valve syndrome is a rare congenital heart disease. Associated with ventricular septal defect, it is considered a rare variant of Tetralogy of Fallot "Tetralogy of Fallot with absent pulmonary valve syndrome". It is characterized by its association with aneurysmal pulmonary arteries responsible for airways compression. Survival to adulthood of this unrepaired congenital heart disease is very rare, and the case of the patient we report in this article is added to the rare cases reported in the literature. Clinical tolerance depends on the degree of severity of the malformation and in particular on the importance of the aneurysmal dilation of the pulmonary arteries, thus determining the age of the diagnosis, the severity of symptoms, and the mode of evolution. Diagnosis of Tetralogy of Fallot with absent pulmonary valve syndrome must be established by transthoracic echography. Other investigations can be of capital contribution, such as thoracic computed tomography angiography and cardiac catheterization. The treatment is surgical and includes closure of the ventricular septal defect, relieve right ventricular outflow tract obstruction, and surgical reduction of the aneurysmal pulmonary arteries.

Abstract
Although several genes involved in the development of Tetralogy of Fallot have been identified, no genetic diagnosis is available for the majority of patients. Low statistical power may have prevented the identification of further causative genes in gene-by-gene survey analyses. Thus, bigger samples and/or novel analytic approaches may be necessary. We studied if a joint analysis of groups of functionally related genes might be a useful alternative approach. Our reanalysis of whole-exome sequencing data identified 12 groups of genes that exceedingly contribute to the burden of Tetralogy of Fallot. Further analysis of those groups showed that genes with high-impact variants tend to interact with each other. Thus, our results strongly suggest that additional candidate genes may be found by studying the protein interaction network of known causative genes. Moreover, our results show that the joint analysis of functionally related genes can be a useful complementary approach to classical single-gene analyses.

Abstract
We present a case of a female American Indian neonate born via a provider unattended home delivery. Her mother received limited prenatal care and the infant was not examined by a healthcare provider until day of life 10 when she presented to the emergency department for evaluation of a skin rash. She was found to have severe hypernatremic dehydration. She was subsequently diagnosed with tetralogy of Fallot, and this was the likely cause of her breastfeeding failure dehydration. The infant underwent careful correction of her electrolyte abnormalities and surgical repair of her cardiac defect on day of life 27. This case highlights the importance of comprehensive care during the prenatal and postpartum/newborn periods, especially in rural locations where access to care can be difficult.

Abstract
OBJECTIVE Adults operated for tetralogy of Fallot (TOF) have high risk of ventricular arrhythmias (VA). QRS duration >180 ms is an established risk factor for VA. We aimed to investigate heart function, prevalence of arrhythmias and sex differences in patients with TOF at long-term follow-up. METHODS We included TOF-operated patients≥18 years from our centre's registry. We reviewed medical records and the most recent echocardiographic exam. VA was recorded on ECGs, 24-hour Holter registrations and from implantable cardioverter defibrillator. RESULTS We included 148 patients (age 37±10 years). Left ventricular global longitudinal strain (LV GLS, -15.8±3.1% vs -18.8±3.2%, p=0.001) and right ventricular (RV) GLS (-15.8±3.9% vs -19.1±4.1%, p=0.001) were lower in men at all ages compared with women. Higher RV D1 (4.3±0.5 cm vs 4.6±0.6 cm, p=0.01), lower ejection fraction (55%±8% vs 50%±9%, p=0.02), lower RV GLS (-18.1±4.0 ms vs -16.1±4.8 ms, p=0.04) and N-terminal pro-brain natriuretic peptide (NT-proBNP) over reference range (n=27 (23%) vs n=8 (77%), p<0.001) were associated with higher incidence of VA. QRS duration was longer in men (151±30 ms vs 128±25 ms, p<0.001). No patients had QRS duration >180 ms. QRS duration did not differ in those with and without VA (143±32 ms vs 137±28 ms, p=0.06). CONCLUSIONS Our results confirmed reduced RV function in adults operated for TOF. Male patients had impaired LV and RV function expressed by lower LV and RV GLS values at all ages. Reduced cardiac function and elevated NT-proBNP were associated with higher incidence of VA and may be important in risk assessment.

Abstract
Surgical repair of Tetralogy of Fallot (TOF) involves a series of steps to remove right ventricular outflow tract and pulmonary artery obstruction. However, the large degree of anatomic variability among preoperative TOF patients may impact the effectiveness of different repair strategies and, subsequently, different geometric modifications for different patients. This study investigates the relationships between geometric and hemodynamic parameters and mechanical energy efficiency for a patient-specific dataset of 16 postoperative TOF repairs, using morphometric and statistical shape analyses, as well as computational fluid dynamics simulations with physiologically-relevant inlet and outlet boundary conditions. Quantitatively, negative correlations were found between the right and left pulmonary artery centerline tract cumulative torsion and energy efficiency (r = - 0.65, p = 0.01, for both). A positive correlation was also found for a statistical shape mode associated with skewing of the geometric sub-regions (r = 0.61, p = 0.01). Qualitatively, medium- and low-efficiency geometries exhibit disturbed flow and much more proximal vortex formation as compared to a high-efficiency geometry. Thus, it is recommended, as much as possible, to both relieve and avoid the introduction of torsion into the patient's anatomy during surgical repair of TOF.

Abstract
OBJECTIVES To determine whether the methylation level of cytosine nucleotides in placental DNA can be used to predict tetralogy of Fallot (TOF) and provide insights into the developmental mechanism of this condition. METHODS Tissue sections were obtained from formalin-fixed paraffin-embedded specimens of placental tissue obtained at birth from eight cases with non-chromosomal, non-syndromic TOF and 10 unaffected newborns. The Illumina Infinium HumanMethylation450 BeadChip assay was used to measure cytosine ('CpG' or 'cg') methylation levels at loci throughout the placental genome. Differential methylation was assessed by comparing the β-values (a measure of the extent of cytosine methylation) for individual CpG loci in fetuses with TOF vs in controls. The most discriminating CpG sites were determined based on a preset cut-off of ≥ 2.0-fold change in the methylation level. The predictive accuracy of CpG loci with significant methylation changes for TOF was determined by the area under the receiver-operating-characteristics curve (AUC). A false-discovery-rate (FDR) P-value < 0.05 was used to define a statistically significant difference in the methylation level. Ingenuity Pathway Analysis (IPA) (Qiagen) was used to identify gene pathways that were significantly overexpressed, and thus altered, in TOF cases compared with controls. RESULTS We found a total of 165 significantly differentially methylated CpG loci in TOF cases compared with controls, in 165 separate genes. These biomarkers demonstrated from fair to excellent individual predictive accuracy for TOF detection, with AUCs ≥ 0.75 (FDR P-value < 0.001 for all). The following CpG loci (gene) had the highest predictive accuracy: cg05273049 (ARHGAP22; AUC = 1.00; 95% CI, 1.00-1.00), cg02540011 (CDK5; AUC = 0.96; 95% CI, 0.87-1.00), cg08404201 (TRIM27; AUC = 0.95; 95% CI, 0.84-1.00) and cg00687252 (IER3; AUC = 0.95; 95% CI, 0.84-1.00). IPA revealed over-representation (dysregulation) of 14 gene pathways involved in normal cardiac development, including cardiomyocyte differentiation via bone morphogenetic protein receptors, cardiac hypertrophy signaling and role of nuclear factor of activated T cells in cardiac hypertrophy. Cardiac hypertrophy is an important feature of TOF. CONCLUSIONS Analysis of placental DNA cytosine methylation changes yielded accurate markers for TOF detection and provided mechanistic information on TOF development. Our work appears to confirm the central role of epigenetic changes and of the placenta in the development of TOF. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
Tetralogy of Fallot is the most common cyanotic congenital heart defect consisting of an overriding aorta, right ventricular outflow obstruction, ventricular septal defect, and right ventricular hypertrophy. Without surgical management, approximately only 3% of patients survive past the age of 40 years. Cases of unoperated patients reaching adulthood have been reported; however, few studies describe treatment guidelines for surgical or therapeutic management. In this article, we report the case of a 59-year-old Hispanic male with unoperated tetralogy of Fallot presenting to our cardiology clinic for initial workup and management.

Abstract
Patients with tetralogy of Fallot (TOF) have abnormal right ventricular (RV) afterload because of residual or recurrent outflow tract obstruction, often with abnormal pulmonary artery (PA) vascular function. The purpose of this study was to determine if RV afterload was independently associated with death and/or heart transplant in patients with TOF. This is a retrospective study of TOF patients that underwent cardiac catheterization for clinical indications at Mayo clinic between 1990 and 2015. Invasively measured RV systolic pressure (RVSP) was used to define RV afterload. To explore clinical utility for echocardiographic estimates of invasive data, correlations between invasive and Doppler-derived indices of RV afterload were examined. Among 266 patients with TOF (age 35 ± 14 years, TOF-pulmonary atresia 117 [44%]), RVSP was 72 ± 28 mm Hg, PA systolic pressure 45 ± 19 mm Hg, mean PA pressure 27 ± 10 mm Hg, pulmonary vascular resistance 4.2 ± 3.1 WU, and PA wedge pressure 14 ± 5 mm Hg. Over a mean follow up of 12.9 years, there were 35 deaths and 4 heart transplants. Invasively measured RVSP (hazard ratio 1.25, 95% confidence interval 1.12 to 1.37; p <0.001) and TOF-pulmonary atresia (hazard ratio 1.18, 95% confidence interval 1.08 to 1.41; p = 0.023) were independent risk factors for death and/or transplant. Doppler-derived RVSP was well-correlated with invasive RVSP (r = 0.92, p <0.001), and was also independently associated with the combined end point. RVSP, a composite measure of RV afterload, is independently prognostic in patients with TOF, and can be reliably assessed using Doppler echocardiography. Further study is required to test whether interventions to reduce RVSP can improve outcomes in patients with TOF.

Abstract
Summary Microtia is a kind of malformation affecting the development of the external ear and middle ear. In China, researches have pointed out that the incidence of microtia was 3.06 per 10 000 people. About 40% of patients with microtia were identified with other systemic malformation, and the commom complications included congenital heart disease, scoliosis, anophthalmia, cleft palate, facial asymmetry, facial asymmetry, etc. Of which, the prevalence of microtia with congenital heart disease was 18.5%, and it was 7% of patients with scoliosis. It is very rare for patients of microtia combined with multi-malformations. In this study, we reported a case of familial microtia combined with tetralogy of Fallot and scoliosis, and undertook a systematic review of the literature.

Abstract
Tetralogy of Fallot (ToF) is the most common type of cyanotic congenital heart disease. Since the first surgical repair in 1954, treatment has continuously improved. The treatment strategies currently used in the treatment of ToF result in excellent long-term survival (30 year survival ranges from 68.5% to 90.5%). However, residual problems such as right ventricular outflow tract obstruction, pulmonary regurgitation, and (ventricular) arrhythmia are common and often require re-interventions. Right ventricular dysfunction can be seen following longstanding pulmonary regurgitation and/or stenosis. Performing pulmonary valve replacement or relief of pulmonary stenosis before irreversible right ventricular dysfunction occurs is important, but determining the optimal timing of pulmonary valve replacement is challenging for several reasons. The biological mechanisms underlying dysfunction of the right ventricle as seen in longstanding pulmonary regurgitation are poorly understood. Different methods of assessing the right ventricle are used to predict impending dysfunction. The atrioventricular, ventriculo-arterial and interventricular interactions of the right ventricle play an important role in right ventricle performance, but are not fully elucidated. In this review we present a brief overview of the history of ToF, describe the treatment strategies currently used, and outline the long-term survival, residual lesions, and re-interventions following repair. We discuss important remaining challenges and present the current state of the art regarding these challenges.

Abstract
Despite of the important technological advances which today allow a precise diagnosis through genetic or imaging studies, one of the fundamental pillars of medical diagnosis is, and always will be, patient examination. The visual identification of the signs that distinguish a disease is still important to make a clinical diagnosis. These very same examination skills and the knowledge on the disorders’ appearance, as well as the technical abilities of the artists that once painted pictures, allow us to diagnose a rosacea among Rembrandt’s self-portraits, or Marfan’s syndrome amidst Egon Schiele’s elongated figures. It is possible to find diseases represented in paintworks from long before someone ever described them in a book, longer even before someone considered them illnesses.

Abstract
BACKGROUND To determine if RV volume was predictive of survival and cardiovascular adverse event (CAE) after pulmonary valve replacement (PVR). METHODS We reviewed the MACHD (Mayo Adult Congenital Heart Disease) database for patients with tetralogy of Fallot (TOF) undergoing PVR, 2000-2015. The patients were divided into quartiles based on RV end-diastolic volume index (RVEDVI); those in the lowest quartile (Group A, n = 46) and the top quartile (Group B, n = 42) were selected as the study cohort. RESULTS In comparison to Group A, Group B patients were older at time of PVR (28 ± 4 vs 33 ± 5 years, P = .011) and had larger RV volumes (RVEDVI 127 [117-138] mL/m2 vs 1 91 [179-208], P < .001; RVESVI 64 [57-73] mL/m2 vs 122 [103-136], P < .001). A total of 28 CAE occurred in 23 patients during 69 (33-94) months follow-up: death (n = 4), heart transplant listing (n = 1), initiation of palliative care (n = 1), heart failure hospitalization (n = 11), stroke (n = 2) and sustained ventricular tachycardia/aborted sudden cardiac death (n = 9). Survival was similar between Groups A and B (95% vs 91% at 10 years, P = .273) but freedom from CAE was significantly lower in Group B (67% vs 36% at 10 years, P = .002). Combination of RVESVI: >95 mL/m2 and tricuspid annular plane systolic excursion/RV systolic pressure (TAPSE/RVSP) <0.4 predicted CAE with sensitivity of 67% and specificity of 92%. CONCLUSION Patients undergoing PVR at larger RV volumes had similar survival but more overall CAE. A larger study population with a longer follow-up will be required to determine if early PVR provides survival benefit in the long-term.

Abstract
BACKGROUND Congenital heart disease (CHD) is a common birth defect affecting approximately 1% of newborns. Great progress has been made in elucidating the genetic aetiology of CHD with advances in genomic technology, which we leveraged in recovering a new pathway affecting heart development in humans previously known to affect heart development in an animal model. METHODS Four hundred and sixteen individuals from Thailand and the USA diagnosed with CHD and/or congenital diaphragmatic hernia were evaluated with chromosomal microarray and whole exome sequencing. The DECIPHER Consortium and medical literature were searched for additional patients. Murine hearts from ENU-induced mouse mutants and transgenic mice were evaluated using both episcopic confocal histopathology and troponin I stained sections. RESULTS Loss of function ROBO1 variants were identified in three families; each proband had a ventricular septal defect, and one proband had tetralogy of Fallot. Additionally, a microdeletion in an individual with CHD was found in the medical literature. Mouse models showed perturbation of the Slit-Robo signalling pathway, causing septation and outflow tract defects and craniofacial anomalies. Two probands had variable facial features consistent with the mouse model. CONCLUSION Our findings identify Slit-Robo as a significant pathway in human heart development and CHD.

Abstract
RATIONALE Absent pulmonary valve syndrome (APVS) is a rare congenital heart disease that is often associated with tetralogy of Fallot (TOF). Here, we report 2 cases of APVS associated with TOF diagnosed via fetal echocardiography and discuss their specific ultrasonographic characteristics. PATIENT CONCERNS Two pregnant women with suspicion of fetal heart anomaly were referred from their local hospitals to our hospital for fetal malformation screening and detailed fetal echocardiography. Color and spectral Doppler flow imaging were utilized to evaluate the axis, size, situs, cardiac chambers, and both inflow and outflow tracts of the heart as well as the great arteries. Both cases had a severe dilatation of the pulmonary trunk and its branches and an absence or dysplasia of the pulmonary valve, which was associated with subaortic ventricular septal defect (VSD) with an overriding aorta. In addition, the fetus in case 1 showed a patent ductus arteriosus, and the fetus in case 2 showed arterial duct agenesis. Furthermore, color Doppler flow imaging showed a bi-directional multicolored flow signal in the pulmonary valve ring. DIAGNOSES Both fetuses were diagnosed with APVS associated with TOF. INTERVENTIONS No therapeutic intervention was performed. OUTCOMES On the request of the pregnant women and their families, both fetuses were aborted. LESSONS Although APVS is a rare congenital heart disease and often associated with TOF, it has an overall poor prognosis. Nowadays, it can be easily diagnosed via ultrasonography because of its typical ultrasonographic features, such as aneurysmal dilatation of pulmonary artery, massive regurgitation of the pulmonary valve, VSD, and an overriding aorta. Therefore, early fetal echocardiography screening should be performed for every fetus.

Abstract
OBJECTIVE To evaluate the effectiveness of pulse oximetry as a screening tool for critical congenital heart defects in newborns. METHODS This cross-sectional study was conducted at the neonatology department of the Children's Hospital and the Institute of Child Health, Lahore, Pakistan, from January to June 2016, and comprised neonates aged up to 07 days. Babies with a prenatal diagnosis of heart defects and those whose parents refused to give consent were excluded. Oxygen saturation of enrolled patients was measured in right index finger (pre-ductal) and in the left big toe (post-ductal) subsequently. Echocardiography was done on all the enrolled babies to confirm the diagnosis. SPSS 19 was used for data analysis. RESULTS Of the 145 babies initially enrolled, 138(95.2%) were included. The overall mean age of the babies was 2.17±1.62 days (range: <24 hours-07 days) whereas the mean birth weight was 2.95±0.47kg (range: <2.5->4kg). Babies with pre- and post-ductal oxygen saturation measurement difference of >3% showed a detection rate of 16(45.7%) for critical congenital heart defects. Sensitivity and specificity of this screening test was calculated to be 76.19% and 83.76%, respectively, while positive and negative predictive values were 45.71% and 95.15%, respectively. CONCLUSIONS The measurement of pre- and post-ductal oxygen saturation by pulse oximetry was an effective screening tool for the detection of critical congenital heart defects in newborns.

Abstract
Objective To evaluate perinatal outcomes and congenital heart defect (CHD) prognosis in a non-selected population. Methods The population-based surveillance data used in this assessment of CHDs were based on birth defect surveillance data collected from 2010–2012 in Liuyang City, China. Infants living with CHDs were followed up for 5 years to determine their prognosis. Prevalence, prenatal diagnosis, perinatal outcomes, and total and type-specific prognosis data were assessed using SPSS 18.0. Results In total, 190 CHD cases were identified among the 53313 included perinatal infants (PIs), indicating a CHD prevalence of 35.64 per 10000 PIs in this non-selected population. The five most frequently identified types of CHDs were ventricular septal defects (VSDs, 38.95%), atrial septal defects (ASDs, 15.79%), cardiomegaly (7.89%), tetralogy of Fallot (TOF, 5.79%), and atrioventricular septal defects (AVSDs, 5.26%). Of the 190 CHD cases, 110 (57.89%) were diagnosed prenatally, 30 (15.79%) were diagnosed with associated malformations, and 69 (36.32%) resulted in termination of pregnancy (TOP). Moreover, 15 (7.89%) PIs died within 7 days after delivery, and 42 (22.10%) died within 1 year. In contrast, 79 (41.58%) were still alive after 5 years. When TOP cases were included, the 5-year survival rate of PIs with prenatally detected CHDs was lower than that of PIs with postnatally detected CHDs (25.45% vs. 63.75%). The CHD subtype associated with the highest rate of infant (less than 1 year old) mortality was transposition of the great arteries (100%). The subtypes associated with higher 5-year survival rates were patent ductus arteriosus (80%), ASD (63.33%), VSD (52.70%) and AVSD (50%). Conclusions The rates of prenatal CHD detection and TOP were high in this study population, and the 5-year survival rate of PIs with CHDs was low. The government should strengthen efforts to educate pediatricians regarding this issue and provide financial assistance to improve the prognosis of infants living with CHDs, especially during the first year of life.

Abstract
We examined CpG island methylation in p16 gene and its effect on p16 protein expression in tetralogy of Fallot (ToF) patients to explore its potential implications in the development and progression of ToF. The study subjects consisted of 75 healthy controls and 63 ToF patients recruited at Linyi People's Hospital between January 2012 and June 2014. The 4 mL of peripheral venous blood of each subject was obtained and saved in ethylene diamine tetraacetic acid (EDTA) tubes. Methylation-specific polymerase chain reaction (MSP) was employed to detect CpG island methylation in p16 promoter region andWestern blotting was used to detect p16 expression of all subjects. Real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) was performed to test p16 mRNA expression. The results showed that p16-methylation rates in ToF group were significantly higher than the control group (ToF group, 58.73%; control group, 13.33%; P < 0.001). Remarkably, Western blotting and FQ-PCR results derived from RVOT revealed that p16 protein expression was significantly lower in ToF group compared tothe control group (0.76 ± 0.21 versus 2.31 ± 0.35; P < 0.001), and p16 gene expression was also markedly decreased in ToF group (1.212 ± 0.152 versus 1.346 ± 0.191, P < 0.001). Additionally, our analysis suggested that CpG island methylation in p16 promoters in ToF patients was negatively correlated with p16 protein and gene expression (both P < 0.05). Our study reports that high CpG island methylation of p16 gene and loss of p16 protein expression associate with the development and progression of ToF, which may have significant therapeutic applications for ToF.

Abstract
BACKGROUND Congenital heart disease (CHD) is the most common human birth defect, and clinicians need to understand the anatomy to effectively care for patients with CHD. However, standard two-dimensional (2D) display methods do not adequately carry the critical spatial information to reflect CHD anatomy. Three-dimensional (3D) models may be useful in improving the understanding of CHD, without requiring a mastery of cardiac imaging. The study aimed to evaluate the impact of 3D models on how pediatric residents understand and learn about tetralogy of Fallot following a teaching session. METHODS Pediatric residents rotating through an inpatient Cardiology rotation were recruited. The sessions were randomized into using either conventional 2D drawings of tetralogy of Fallot or physical 3D models printed from 3D cardiac imaging data sets (cardiac MR, CT, and 3D echocardiogram). Knowledge acquisition was measured by comparing pre-session and post-session knowledge test scores. Learner satisfaction and self-efficacy ratings were measured with questionnaires filled out by the residents after the teaching sessions. Comparisons between the test scores, learner satisfaction and self-efficacy questionnaires for the two groups were assessed with paired t-test. RESULTS Thirty-five pediatric residents enrolled into the study, with no significant differences in background characteristics, including previous clinical exposure to tetralogy of Fallot. The 2D image group (n = 17) and 3D model group (n = 18) demonstrated similar knowledge acquisition in post-test scores. Residents who were taught with 3D models gave a higher composite learner satisfaction scores (P = 0.03). The 3D model group also had higher self-efficacy aggregate scores, but the difference was not statistically significant (P = 0.39). CONCLUSION Physical 3D models enhance resident education around the topic of tetralogy of Fallot by improving learner satisfaction. Future studies should examine the impact of models on teaching CHD that are more complex and elaborate.

Abstract
The comorbidity of structural or genetic diseases with schizophrenia is seen as an opportunity to understand the formation of schizophrenia. This case report presents a patient with comorbidity of schizophrenia, tetralogy of Fallot (TOF) and total situs inversus. TOF is a cyanotic heart disease, which can be linked to 22q11 deletion and trisomy 21. Situs inversus totalis (SIT) is a congenital condition in which the major visceral organs, including the heart, are positioned in a mirror image from normal conditions. The comorbidity of TOF and SIT is quite rare. In our case report, schizophrenia is added to this rare comorbidity. This case report discussed the comorbidity and probable causal relationships. Furthermore, the research method of how transposition in internal organs is reflected in brain lateralization is also presented.

Abstract
Tetralogy of Fallot is a congenital disease caused by structural defects within the heart that can lead to cyanosis. The purpose of this case report is to discuss the use of PracaSil-Plus, a proprietary topical anhydrous silicone base containing pracaxi oil, in scar-management therapy, following open-heart surgery on a pediatric patient with tetralogy of Fallot. The Patient and Observer Scar Assessment Scale was the research instrument used to evaluate for efficacy of the scar therapy. Following 8 weeks of treatment with PracaSil-Plus, reduction in scores were observed for scar color, stiffness, thickness, and irregularity, with improvements of 87.5%, 90.0%, 66.7%, and 66.7% from baseline, respectively. The post-treatment scar was similar to normal skin in appearance, with a 77.8% improvement in the total score. These results show that PracaSil-Plus may be a valuable option for practitioners and pharmacists to consider in pediatric scar-management therapy.

Abstract
Tetralogy of Fallot often requires reconstruction of the right ventricular outflow tract with a transannular patch (TAP), but this renders the pulmonary valve incompetent and eventually leads to right ventricular dysfunction. We retrospectively evaluated the efficacy of a reconstructed pulmonary valve and annulus in 70 patients who underwent, from December 2006 through December 2010, complete correction of tetralogy of Fallot. We divided the 70 patients into 2 groups in accordance with whether they required (n=50) or did not require (n=20) a TAP. We used autologous untreated pericardium to fashion the TAP and to create both an annulus of the correct size and a competent pulmonary valve with native leaflets. We evaluated the efficiency of this procedure both functionally and anatomically. The median age of the patients was 11 years (range, 2-38 yr). There were 56 males, with no significant difference in sexual distribution between groups. The clinical follow-up was 88% for 57.5 months, and the echocardiographic follow-up was 80% for 36 months. There was no significant difference in outflow gradient or in the occurrence of pulmonary insufficiency between the TAP group (none, 31; mild, 12; moderate, 6; and severe, 1) and the No-TAP group (none, 16; moderate, 2; and severe, 2) (P=0.59). Nor was there any thickening or calcification in the constructed valves. We conclude that pulmonary valves constructed of untreated autologous pericardium performed as well as native valves after total tetralogy of Fallot correction at midterm.

Abstract
BACKGROUND Congenital heart diseases cause significant childhood morbidity and mortality. Several restricted studies have been conducted on the epidemiology in Nigeria. No truly nationwide data on patterns of congenital heart disease exists. OBJECTIVES To determine the patterns of congenital heart disease in children in Nigeria and examine trends in the occurrence of individual defects across 5 decades. METHOD We searched PubMed database, Google scholar, TRIP database, World Health Organisation libraries and reference lists of selected articles for studies on patterns of congenital heart disease among children in Nigeria between 1964 and 2015. Two researchers reviewed the papers independently and extracted the data. Seventeen studies were selected that included 2,953 children with congenital heart disease. RESULTS The commonest congenital heart diseases in Nigeria are ventricular septal defect (40.6%), patent ductus arteriosus (18.4%), atrial septal defect (11.3%) and tetralogy of Fallot (11.8%). There has been a 6% increase in the burden of VSD in every decade for the 5 decades studied and a decline in the occurrence of pulmonary stenosis. Studies conducted in Northern Nigeria demonstrated higher proportions of atrial septal defects than patent ductus arteriosus. CONCLUSIONS Ventricular septal defects are the commonest congenital heart diseases in Nigeria with a rising burden.

Abstract
Patients with repaired pulmonary stenosis (PS) or tetralogy of Fallot (TOF) both develop pulmonary regurgitation (PR) leading to right ventricular (RV) dilatation and dysfunction. We aimed to characterize differential effects of chronic PR in these populations. Patients with surgically repaired PS were matched 1:2 by age and PR fraction with patients with TOF. Patients with previous pulmonary valve replacement were excluded. Cardiovascular magnetic resonance data were compared; peak longitudinal and circumferential systolic strain by feature tracking were compared to evaluate differential contribution of the RV sinus and outflow tract, respectively. PS (n = 24, 41 ± 13 years old) and TOF (n = 47, 39 ± 13 years old) patients did not differ in RV end-diastolic volume (153 ± 45 vs 154 ± 45 ml/m(2), p = 0.99) or diastolic function. However, patients with PS had preserved RV ejection fraction (54.3 ± 4.4% vs 48.0 ± 7.1%, p <0.0001). Differences were greater in RV circumferential (-15.8 ± 3.3 vs -11.8 ± 3.4, p <0.0001) than longitudinal strain (-18.0 ± 3.8 vs -15.9 ± 3.8, p = 0.04), with particular decrease in the infundibulum (-17.4 ± 7.5 vs -6.8 ± 6.3, p <0.0001). Late gadolinium enhancement in the RV outflow tract was more frequent in patients with TOF (70.2% vs 45.8%, p = 0.001). In conclusion, surgical repair of PS leads to similar RV dilatation and diastolic dysfunction compared to patients with TOF, but differential effects on ventricular systolic function, largely related to differences in the outflow tract. With different patterns of scarring and ventricular remodeling, further study is needed to clarify whether criteria for pulmonary valve replacement in patients with PS should differ from those with TOF.

Abstract
Duplication 17pll.2 syndrome is a recent recognized syndrome with multiple congenital anomalies and mental retardation. Most patients with duplication 17p11.2 syndrome harbor a common 3.7 Mb duplication (17p.11.2 duplication syndrome) resulting in congenital anomalies, neurodevelopmental and behavioral phenotypes. We report a case with spina bifida, tetralogy of Fallot and a small duplication (932 Kb) of 17pl1.2 containing approximately 20 genes, detected by array-CGH. We describe clinical features not reported previously for microduplication of 17p11.2.

Abstract
Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart defect. The actual treatment relies on cardio-surgery--complete correction within the infant age. Without surgery only 10% of subjects survived 3rd decade and only 3-5% of subjects were able to survive until their 40th. This particular paper is dedicated to case of a 69-years old male subject with positive history of uncorrected ToF due to his refusal of surgery, ischemic cardiac disease NYHA III-IV and chronic kidney failure. This subject was hospitalized within the department of internal medicine due to several days of chest pain connected with lower extremities oedemas and dyspnoeic syndrome after minimal physical load. Provided echocardiography revealed pulmonary artery stenosis, severe tricuspid insufficiency, concentric hypertrophy of ventricles, ventricular septal defect, dextroposition of aorta and severe pericardial effusion. Chest X-ray proved massive pleura effussion. The actual conditions of subject improved significantly after onset of diuretics, antiarrhytmics and providing of pleural punction. Subject has been discharged. Cases of ToF presented within available sources in older population were associated with left ventricular hypertrophy and hypoplastic pulmonary artery and slow subpulmonal obstruction development which also presented within our subject. Left ventricular hypertrophy has a potential to develop continuously and therefore its benefits can be visible within adult age.

Abstract
BACKGROUND AND AIM OF THE STUDY Cardiac magnetic resonance (CMR) is the 'gold standard' for quantifying pulmonic regurgitation (PR) in adults with congenital heart disease, but remains costly and is less readily available than echocardiography. Qualitative echocardiographic assessment of PR is challenging, and guiding criteria are limited. It is unknown if echocardiography is sufficient to screen for significant PR. The study aim was to determine whether cardiac MRI provides additional benefit in the assessment of PR in adults with congenital heart disease. METHODS Patients with repaired tetralogy of Fallot or congenital pulmonic stenosis after valvotomy undergoing transthoracic echocardiography and CMR with no interval intervention were identified from a prospective registry. Patients with greater than mild pulmonic stenosis, residual ventricular septal defect or poor echocardiographic windows were excluded. Whole-cohort and subgroup (tetralogy of Fallot versus pulmonic stenosis) analyses for inter-modality agreement were performed. RESULTS A total of 48 patients (24 men, 24 women; mean age 43 +/- 12 years) was included in the analysis. The unweighted kappa value for the two modalities was 0.30, suggesting 'fair' agreement, though only 52% had matching PR assessments. The indexed right ventricular end-systolic volume (RVESVi) correlated closely with cardiac MRI-monitored PR (p = 0.011 by analysis of variance), but not with that monitored with echocardiography (p = 0.081). Subgroup analysis demonstrated less inter-modality agreement in the tetralogy of Fallot population (kappa 0.25) than in the pulmonic stenosis population (kappa 0.35). CONCLUSION CMR measurement of PR correlates closely with the RVESVi, and appears superior to echocardiography when assessing patients at risk for PR. The study results suggest a vital role for CMR whenever significant PR is suspected in the adult congenital heart disease population.

Abstract
A 32 year old male patient was admitted with exertional dyspnea for long duration with features of right sided failure. On examination, it seemed to be a congenital cyanotic heart disease with decrease pulmonary flow. Echocardiography showed a malaligned VSD with pulmonary stenosis with severe AR and the total regurgitation volume was going to the RV instead of going to both the ventricles leading to dilatation of right ventricle and failure.

Abstract
OBJECTIVES A technique that uses two-dimensional images to create a knowledge-based, three-dimensional model was tested and compared to magnetic resonance imaging. BACKGROUND Measurement of right ventricular volumes and function is important in the follow-up of patients after pulmonary valve replacement. Magnetic resonance imaging is the gold standard for volumetric assessment. Echocardiographic methods have been validated and are attractive alternatives. METHODS Thirty patients with tetralogy of Fallot (25 ± 14 years) after pulmonary valve replacement were examined. Magnetic resonance imaging volumetric measurements and echocardiography-based three-dimensional reconstruction were performed. End-diastolic volume, end-systolic volume, and ejection fraction were measured, and the results were compared. RESULTS Magnetic resonance imaging measurements gave coefficient of variation in the intraobserver study of 3.5, 4.6, and 5.3 and in the interobserver study of 3.6, 5.9, and 6.7 for end-diastolic volume, end-systolic volume, and ejection fraction, respectively. Echocardiographic three-dimensional reconstruction was highly feasible (97%). In the intraobserver study, the corresponding values were 6.0, 7.0, and 8.9 and in the interobserver study 7.4, 10.8, and 13.4. In comparison of the methods, correlations with magnetic resonance imaging were r = 0.91, 0.91, and 0.38, and the corresponding coefficient of variations were 9.4, 10.8, and 14.7. Echocardiography derived volumes (mL/m(2)) were significantly higher than magnetic resonance imaging volumes in end-diastolic volume 13.7 ± 25.6 and in end-systolic volume 9.1 ± 17.0 (both P < .05). CONCLUSIONS The knowledge-based three-dimensional right ventricular volume method was highly feasible. Intra and interobserver variabilities were satisfactory. Agreement with magnetic resonance imaging measurements for volumes was reasonable but unsatisfactory for ejection fraction. Knowledge-based reconstruction may replace magnetic resonance imaging measurements for serial follow-up, whereas magnetic resonance imaging should be used for surgical decision making.
