Abstract
Background Pulmonary valve replacement in patients with congenital heart diseases and heart failure is challenging. Case summary Here, we describe a case of a patient who had surgical fallot repair with chronic heart failure. Investigations found severe biventricular dysfunction and enlargement due to chronic pulmonary regurgitation. The right ventricle outflow tract was tortuous and large with a diameter of 35 mm. Percutaneous pulmonary valve implantation (PPVI) was done after a challenging pre-stenting. A 32 mm Myval valve over-sized to 35 mm was used for PPVI, which yielded a good result. Discussion A 32 mm Myval valve is effective at extending the possibilities of PPVI in a large and tortuous right ventricle outflow tract not accessible for the other valves.

Abstract
AIM Ventricular arrhythmias (VAs) are the most common cause of death in patients with repaired Tetralogy of Fallot (rTOF). However, risk stratifying remains challenging. We examined outcomes following programmed ventricular stimulation (PVS) with or without subsequent ablation in patients with rTOF planned for pulmonary valve replacement (PVR). METHODS We included all consecutive patients with rTOF referred to our institution from 2010 to 2018 aged ≥18 years for PVR. Right ventricular (RV) voltage maps were acquired and PVS was performed from two different sites at baseline, and if non-inducible under isoproterenol. Catheter and/or surgical ablation was performed when patients were inducible or when slow conduction was present in anatomical isthmuses (AIs). Postablation PVS was undertaken to guide implantable cardioverter-defibrillator (ICD) implantation. RESULTS Seventy-seven patients (36.2 ± 14.3 years old, 71% male) were included. Eighteen were inducible. In 28 patients (17 inducible, 11 non-inducible but with slow conduction) ablation was performed. Five had catheter ablation, surgical cryoablation in 9, both techniques in 14. ICDs were implanted in five patients. During a follow-up of 74 ± 40 months, no sudden cardiac death occurred. Three patients experienced sustained VAs, all were inducible during the initial EP study. Two of them had an ICD (low ejection fraction for one and important risk factor for arrhythmia for the second). No VAs were reported in the non-inducible group (p < .001). CONCLUSION Preoperative EPS can help identifying patients with rTOF at risk for VAs, providing an opportunity for targeted ablation and may improve decision-making regarding ICD implantation.

Abstract
BACKGROUND The adult population of repaired tetralogy of Fallot is increasing and at risk of pre-mature death and arrhythmia. This study evaluates risk factors for adverse outcome and the effect of pulmonary valve replacement within a national cohort. METHODS A retrospective cohort study of 341 adult repaired tetralogy of Fallot (16-72 years) managed through a single national service was undertaken incorporating over 1200 patient-years of follow-up. Demographics, cardiopulmonary exercise testing, cardiac magnetic resonance, reintervention (including pulmonary valve replacement), and clinical events were analysed. The influence of these parameters on a primary outcome (death or arrhythmia) was evaluated. RESULTS Compared with an age-/gender-matched population, patients experienced a reduced survival, particularly males over 55 years (standardised mortality ratio : 6.12, 95% CI: 1.64-15.66, p = 0.004). Cox proportional hazards modelling identified increased indexed right ventricle (RV) end-diastolic volume (hazard ratio (HR): 2.86, 95% CI: 1.4-5.85, p = 0.004) and female gender (HR (male): 0.37, 95% CI: 0.14-0.98, p = 0.045) to be predictors significantly associated with the primary outcome. Pulmonary valve replacement undertaken at indexed RV end-diastolic volume = 145 ml/m2 reduced RV volumes and QRS duration but did not improve cardiopulmonary exercise testing nor NYHA class. Pulmonary valve replacement during cohort period was associated with increased risk of primary outcome (HR: 2.82, 95% CI: 1.36-5.86, p = 0.005). CONCLUSIONS Although the majority of adult tetralogy of Fallot were asymptomatic in NYHA 1, cardiopulmonary exercise testing revealed important deficits. Tetralogy of Fallot survival was reduced compared to the general population. Female gender and increasing RV end-diastolic volume predicted adverse events. Pulmonary valve replacement reduced RV volumes and QRS duration but did not improve primary outcome.

Abstract
Background Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease (CHD). Abnormal aortic dimensions and elasticity parameters have been long described for corrected TOF (cTOF) together with left ventricular (LV) rotational abnormalities, but results are conflicting. The present study focuses on investigating LV rotational mechanics in cTOF, and possible correlation of these parameters with aortic elasticity. It was also aimed to be examined whether different surgical strategies have any effect on these results. Methods The study involved 26 adult cTOF patients, from which 14 had palliative surgery first and a late total correction (pcTOF), while early total correction was the treatment of choice in 12 patients (etrTOF). Their results were compared to those of 37 age- and gender-matched healthy adults. Routine transthoracic two-dimensional Doppler echocardiography extended with assessment of aortic elastic properties and three-dimensional speckle-tracking echocardiography (3DSTE) was performed in all cTOF patients and controls. Results Sixteen out of 26 cTOF patients showed normally directed LV rotational mechanics, while apical or basal LV rotations were in the same clockwise or counterclockwise directions in 7 and 3 cTOF cases, respectively (LV 'rigid body rotation', RBR). Significantly reduced LV apical rotation and twist could be demonstrated in all cTOF patients with preserved LV basal rotation regardless of previous procedure. pcTOF patients showed significantly reduced LV apical rotation as compared to that of etrTOF cases. Significant correlations could be demonstrated between LV apical rotation and aortic stiffness index (r=-0.55, P=0.03) and aortic distensibility (r=0.52, P=0.04). Conclusions Significant LV rotational abnormalities could be demonstrated in cTOF with the high prevalence of LV-RBR. pcTOF patients showed significantly reduced LV apical rotation as compared to that of etrTOF cases. Unexpected abnormal physiologic response of LV rotational mechanics to increased aortic stiffness can be detected in cTOF patients without LV-RBR.

Abstract
Background Aortopathy is a common phenomenon in tetralogy of Fallot (TOF). The current study was designed to detect left ventricular (LV) deformation abnormalities and its relation to aortic stiffness in corrected TOF (cTOF) using the novel three-dimensional (3D) speckle-tracking echocardiography (3DSTE). Detailed comparative analysis between patients with early palliation-late correction (pcTOF) and early total reconstruction (etrTOF) was also performed. Methods The present study consisted of 28 cTOF patients (35.0±15.7 years, 11 males) from which 15 and 13 proved to be pcTOF and etrTOF, respectively. Their clinical parameters were compared to those of 39 matched healthy adults (35.5±6.0 years, 16 males). Results cTOF patients showed significantly lower global LV longitudinal, circumferential and area strains as compared to controls. In etrTOF patients, global LV 3D strain was higher than in controls. In pcTOF patients, all LV strains proved to be significantly lower as compared to those of etrTOF patients and controls. In all cTOF patients, several moderate correlations could be detected between LV strain parameters and aortic elastic properties. Conclusions Significant LV deformational abnormalities could be demonstrated in cTOF patients. etrTOF patients have beneficial LV strain parameters as compared to those of pcTOF patients. LV strains show correlations with aortic elastic properties.

Abstract
Background: The population of adults with tetralogy of Fallot (TOF) or pulmonary atresia with ventricular septal defect (PA/VSD) is growing and aging. Data regarding older patients are scarce. Prognostic outcome parameters in adults with TOF or PA/VSD ≥ 40 years were studied. Methods: This was a retrospective study of patients ≥ 40 years of age during the study period (January 2005–March 2018). Major adverse cardiac events (MACE) were a combined primary endpoint including death from any cause, prevented sudden cardiac death, pacemaker implantation, arrhythmia, and new-onset heart failure. Additionally, MACE II (secondary endpoint) was a combination of death from any cause and prevented sudden cardiac death. Results: 184 (58.7% female, mean age 45.3 ± 7.2 years) patients were included (159 (86.4%) TOF and 25 (13.6%) PA/VSD). During a median follow-up of 3.1 years (IQR: 0.6–6.5), MACE occurred in 35 and MACE II in 13 patients. On multivariable analysis, New York Heart Association class [HR: 2.1, 95% CI: 1.2–3.6, p = 0.009] emerged as an independent predictor for MACE, and age at corrective surgery [HR: 13.2, 95% CI: 1.6–107.1, p = 0.016] for MACE II. Conclusions: Adults with TOF or PA/VSD ≥ 40 years are burdened with significant morbidity and mortality. New York Heart Association class and age at corrective surgery were independent predictors of outcome.

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
Introduction: There is a dearth of literature on tetralogy of fallot (TOF) in children in Sub-Saharan Africa. This study up aims to describe the prevalence, clinical profile and associated cardiac anomaly of children diagnosed with TOF documented over an eight year period in a tertiary hospital in South Western Nigeria.
Methods: A prospective review of all consecutive cases of TOF diagnosed with echocardiography at the Lagos State University Teaching Hospital (LASUTH) between January 2007 and December 2014. Data were analyzed using SPSS version 20. Tables and charts were used to depict those variables. Descriptive statistic are presented as percentages or means and standard deviation. Means of normally distributed variables were compared using the student t test and proportions using chi-square test. Skewed distribution were analyzed using appropriate non-parametric tests. Level of significance set at P < 0.05.
Result: The prevalence of TOF among children presenting at LASUTH at the study period was 4.9 per 10 000 while its prevalence among those with congenital heart disease was 16.9%. There was a male predominance and most children presented within 1-5 years of age. Chromosomal abnormalities such as Down syndrome, Turners syndrome and CATCH 22 syndrome were documented in some subjects. Some of the subjects had atypical presentation.
Conclusion: TOF is as common in Nigeria as other parts of the world, there is a need to established cardiac centers to salvage these children. Collaboration from developed countries will be helpful in this resource limited region.

Abstract
Arrhythmias in adults with congenital heart disease, most commonly related to previous surgical procedures, are a frequent comorbidity in this growing population thanks to the improved outcome of surgical techniques. Re-entrant circuits around areas of scarring and natural barriers, combined with abnormal haemodynamics and the underlying anatomy, are the most common cause for these arrhythmias. They are often poorly tolerated and medical treatment is frequently inadequate. In recent years, catheter ablation has emerged as a successful therapeutic option. New advanced techniques such as the use of modern three-dimensional (3D) navigation systems have contributed to better understanding of the arrhythmia mechanisms and higher success rates of the ablation procedures. In this article we briefly summarise the characteristics of the most common arrhythmias in this patient population and some key aspects in their treatment by catheter ablation.

Abstract
Double aortic arch (DAA) is a common vascular ring. It may occur in isolation or coexist with various types of congenital heart disease. The anomaly usually presents in early infancy. This reports a 23yr old male presenting with dysphagia, who was found to have a double aortic arch and tetralogy of Fallot. Both lesions were successfully corrected surgically.
