RESUMEN
BACKGROUND AND AIMS: Transcatheter pulmonary valve implantation (TPVI) is indicated to treat right-ventricular outflow tract (RVOT) dysfunction related to congenital heart disease (CHD). Outcomes of TPVI with the SAPIEN 3 valve that are insufficiently documented were investigated in the EUROPULMS3 registry of SAPIEN 3-TPVI. METHODS: Patient-related, procedural, and follow-up outcome data were retrospectively assessed in this observational cohort from 35 centres in 15 countries. RESULTS: Data for 840 consecutive patients treated in 2014-2021 at a median age of 29.2 (19.0-41.6) years were obtained. The most common diagnosis was conotruncal defect (70.5%), with a native or patched RVOT in 50.7% of all patients. Valve sizes were 20, 23, 26, and 29â mm in 0.4%, 25.5%, 32.1%, and 42.0% of patients, respectively. Valve implantation was successful in 98.5% [95% confidence interval (CI), 97.4%-99.2%] of patients. Median follow-up was 20.3 (7.1-38.4) months. Eight patients experienced infective endocarditis; 11 required pulmonary valve replacement, with a lower incidence for larger valves (P = .009), and four experienced pulmonary valve thrombosis, including one who died and three who recovered with anticoagulation. Cumulative incidences (95%CI) 1, 3, and 6 years after TPVI were as follows: infective endocarditis, 0.5% (0.0%-1.0%), 0.9% (0.2%-1.6%), and 3.8% (0.0%-8.4%); pulmonary valve replacement, 0.4% (0.0%-0.8%), 1.3% (0.2%-2.4%), and 8.0% (1.2%-14.8%); and pulmonary valve thrombosis, 0.4% (0.0%-0.9%), 0.7% (0.0%-1.3%), and 0.7% (0.0%-1.3%), respectively. CONCLUSIONS: Outcomes of SAPIEN 3 TPVI were favourable in patients with CHD, half of whom had native or patched RVOTs.

OBJECTIVES: UK single ventricle (SV) palliation outcomes after first postnatal procedure (FPP) are well documented. However, survival determinants from fetal diagnosis to FPP are lacking. To better inform parental-fetal counselling, we examined factors favouring survival at two large UK centres. DESIGN: Retrospective multicentre cohort study. SETTING: Two UK congenital cardiac centres: Leeds and Birmingham. PATIENTS: SV fetal diagnoses from 2015 to 2021. MAIN OUTCOME MEASURES: Survival from fetal diagnosis with intention to treat (ITT) to birth and then FPP. Maternal, fetal and neonatal risk factors were assessed. RESULTS: There were 666 fetal SV diagnoses with 414 (62%) ITT. Of ITT, 381 (92%) were live births and 337 (81%) underwent FPP. Survival (ITT) to FPP was notably reduced for severe Ebstein's 14/22 (63.6%), unbalanced atrioventricular septal defect 32/45 (71%), indeterminate SV 3/4 (75%), mitral atresia 8/10 (80%) and hypoplastic left heart syndrome 127/156 (81.4%). Biventricular pathway was undertaken in five (1%). After multivariable adjustment, prenatal risk factors for mortality were increasing maternal age (OR 1.05, 95% CI 1.0 to 1.1), non-white ethnicity (OR 2.6, 95% CI 1.4 to 4.8), extracardiac anomaly (OR 6.34, 95% CI 1.8 to 22.7) and hydrops (OR 7.39, 95% CI 1.2 to 45.1). Postnatally, prematurity was significantly associated with mortality (OR 6.3, 95% CI 2.3 to 16.8). CONCLUSIONS: Around 20% of ITT fetuses diagnosed with SV will not reach FPP. Risk varies according to the cardiac lesion and is significantly influenced by the presence of an extracardiac anomaly, fetal hydrops, ethnicity, increasing maternal age and gestation at birth. These data highlight the need for fetal preprocedure data to be used in conjunction with procedural outcomes for fetal counselling.

BACKGROUND: Educational attainment in children with congenital heart disease (CHD) within the UK has not been reported, despite the possibility of school absences and disease-specific factors creating educational barriers. METHODS: Children were prospectively recruited to the Born in Bradford birth cohort between March 2007 and December 2010. Diagnoses of CHD were identified through linkage to the congenital anomaly register and independently verified by clinicians. Multivariable regression accounted for relevant confounders. Our primary outcome was the odds of 'below expected' attainment in Maths, Reading and Writing at ages 4-11 years. RESULTS: Educational records of 139 children with non-genetic CHD were compared to 11 188 age-matched children with no major congenital anomaly. Children with CHD had significantly higher odds of 'below expected' attainment in Maths at age 4-5 years (Odds Ratio 1.64, 95% CI 1.07-2.52), age 6-7 (OR 2.03, 95% CI 1.32-3.12), and age 10-11 (OR 2.28, 95% CI 1.01-5.14). Odds worsened with age, with similar results for Reading and Writing. The odds of receiving special educational needs support reduced with age for children with CHD relative to controls (age 4-5: OR 4.84 (2.06-11.40); age 6-7: OR 3.65 (2.41-5.53); age 10-11: OR 2.73 (1.84-4.06)). Attainment was similar for children with and without exposure to cardio-pulmonary bypass. Lower attainment was strongly associated with the number of pre-school hospital admissions. CONCLUSIONS: Children with CHD have lower educational attainment compared to their peers. Deficits are evident from school entry and increase throughout primary school.
RESUMEN
The GORE CARDIOFORM atrial septal defect (ASD) Occluder (GCA) is composed of a platinum-filled nitinol wire frame covered with expanded polytetrafluoroethylene, making it softer and more conformable compared with nitinol mesh devices. After the ASSURED clinical study confirmed the efficacy and safety of the device, it received U.S. Food and Drug Administration approval and a European conformity mark. Our aim was to understand the learning curve implicated in using the GCA for ASD closure in paediatric and adult patients as well as to study the early outcomes. To this end, a review of ASD device closures with GCA in 4 UK centres was conducted between January 2020 and January 2023. Implantation success was the primary outcome; the secondary outcomes were serious adverse events, including new onset arrhythmia. In all, 135 patients were included, and 128 (95%) had successful ASD device closure with GCA. The median patient age was 49 years, the median defect size was 18 mm, and the median device size was 37 mm. The median follow-up time was 6 months (interquartile range 1-14). One device embolisation occurred, and 15 patients (12% of GCA implantations) developed new onset arrhythmia - this was not related to patient age, defect diameter or device oversizing but was positively associated with device size. With growing experience using GCA, the device can be applied to a wide variety of ASD sizes and morphologies. Given the number of successful implantations with an absence of aortic erosion, as well as the ability to perforate through the device should procedures be required in the left atrium, the GCA device is an important addition for interventionists who close atrial septal defects.

Background: Gore Cardioform Atrial Septal Defect Occluder (GCA) is composed of a platinum-filled nitinol wire frame covered with expanded polytetrafluoroethylene (ePTFE). This makes the device highly occlusive and resistant to residual shunts through the device, as well as conforming well to the surrounding anatomy. In defects with poor rims to hold a device for closure or where one of the 'rims' is the free wall of the left ventricle, such as in a post-infarct apical ventricular septal defect (VSD), successful closure with standard nitinol mesh devices can be unachievable. Case summary: We present the occlusion of a post-myocardial infarction VSD with a GCA device in a critically ill patient at risk for closure failure and intravascular haemolysis with conventional nitinol mesh devices. The device conformed well to the anatomy even in the absence of an apical interventricular septum. Discussion: GCA can be used for intracardiac high-velocity shunts in selected cases where conventional devices are unsuitable due to haemolysis or poor tissue and poor rims. With growing experience using GCA for the closure of atrial septal defects, interventionists should consider the potential advantages of ePTFE material and apply them to other lesions where these could be beneficial for patients.
RESUMEN
Low fruit and vegetable consumption is a major modifiable risk factor for raised blood pressure (BP), but it is unknown how heterogeneity in national supply has contributed to BP trends. To address this, we characterised supply trends from 1975 to 2015 and whether it met WHO recommendations. We then examined associations with three metrics: systolic, diastolic and raised BP. We used ecological data on fruit and vegetable supply and on BP for 159 countries. We examined trends in fruit and vegetable supply from 1975 to 2015 by country and World Bank income region. Multivariable linear regression was used to examine cross-sectional associations with BP. Global fruit and vegetable supply increased from 1975 to 2015, but with heterogeneous national and regional trends. While WHO recommendations were met globally, this target was not met in almost half the countries, of which many were low-income countries. Significant associations between combined fruit and vegetable supply and raised BP were observed. Over the past four decades, combined fruit and vegetable supply has been consistently and strongly associated with lower prevalence of raised BP globally. However, the heterogeneous regional trends in fruit and vegetable supply underpin the need for international organisations and individual governments to introduce or strengthen policies for increased fruit and vegetable supply to reduce the burden of non-communicable diseases at national and global levels.
RESUMEN
Background: Chronic complete vascular occlusion causes significant morbidity and mortality in patients with congenital heart disease (CHD). The diversity of lesions, lack of dedicated equipment, and small number of procedures performed by individual operator continue to pose a challenge to congenital interventional cardiologists. Case summary: We report two cases of percutaneous recanalization in CHD using percutaneous coronary intervention (PCI) equipment for chronic total occlusion (CTO). Discussion: Careful pre-procedural planning, access site choice, use of catheter guiding systems for support, and selection of penetrating guidewires and techniques used in CTO-PCIs are key steps to a successful outcome.
RESUMEN
Background: Contactless photoplethysmography (PPG) potentially affords the ability to obtain vital signs in pediatric populations without disturbing the child. Most validity studies have been conducted in laboratory settings or with healthy adult volunteers. This review aims to evaluate the current literature on contactless vital signs monitoring in pediatric populations and within a clinical setting. Methods: OVID, Webofscience, Cochrane library, and clinicaltrials.org were systematically searched by two authors for research studies which used contactless PPG to assess vital signs in children and within a clinical setting. Results: Fifteen studies were included with a total of 170 individuals. Ten studies were included in a meta-analysis for neonatal heart rate (HR), which demonstrated a pooled mean bias of -0.25 (95% limits of agreement (LOA), -1.83 to 1.32). Four studies assessed respiratory rate (RR) in neonates, and meta-analysis demonstrated a pooled mean bias of 0.65 (95% LOA, -3.08 to 4.37). All studies were small, and there were variations in the methods used and risk of bias. Conclusion: Contactless PPG is a promising tool for vital signs monitoring in children and accurately measures neonatal HR and RR. Further research is needed to assess children of different age groups, the effects of skin type variation, and the addition of other vital signs.
RESUMEN
Background: Refractory chylous effusions due to lymphatic dysplasia related to Noonan syndrome cause significant morbidity and mortality due to protein and immunoglobulin losses. Very few cases have been published reporting successful treatment of patients with trametinib where all conventional treatments had failed. Case summary: We present a girl with Noonan syndrome and hypertrophic cardiomyopathy who presented with life-threatening refractory chylothorax where all conventional treatment options failed. She was successfully treated with mitogen-activated extracellular signal-regulated kinase inhibitor trametinib. Discussion: MEK inhibition with trametinib is emerging as a possible salvage treatment option for a subset of patients with Noonan syndrome and severe pulmonary lymphangiectasia. More experience is required to establish optimal treatment regimen and long-term outcomes.
RESUMEN
Cardiac output monitoring enables physiology-directed management of critically ill children and aids in the early detection of clinical deterioration. Multiple invasive techniques have been developed and have demonstrated ability to improve clinical outcomes. However, all require invasive arterial or venous catheters, with associated risks of infection, thrombosis and vascular injury. Non-invasive monitoring of cardiac output and fluid responsiveness in infants and children is an active area of interest and several proven techniques are available. Novel non-invasive cardiac output monitors offer a promising alternative to echocardiography and have proven their ability to influence clinical practice. Assessment of perfusion remains a challenge; however, technologies such as near-infrared spectroscopy and photoplethysmography may prove valuable clinical adjuncts in the future.

INTRODUCTION AND BACKGROUND: Mortality between stages 1 and 2 single-ventricle palliation is significant. Home-monitoring programmes are suggested to reduce mortality. Outcomes and risk factors for adverse outcomes for European programmes have not been published. AIMS: To evaluate the performance of a home-monitoring programme at a medium-sized United Kingdom centre with regards survival and compare performance with other home-monitoring programmes in the literature. METHODS: All fetal and postnatal diagnosis of a single ventricle were investigated with in-depth analysis of those undergoing stage 1 palliation and entered the home-monitoring programme between 2016 and 2020. The primary outcome was survival. Secondary outcomes included multiple parameters as potential predictors of death or adverse outcome. RESULTS: Of 217 fetal single-ventricle diagnoses during the period 2016-2020, 50.2% progressed to live birth, 35.4% to stage 1 and 29.5% to stage 2. Seventy-four patients (including 10 with postnatal diagnosis) entered the home-monitoring programme with six deaths making home-monitoring programme mortality 8.1%. Risk factors for death were the hybrid procedure as the only primary procedure (OR 33.0, p < 0.01), impaired cardiac function (OR 10.3, p < 0.025), Asian ethnicity (OR 9.3, p < 0.025), lower mean birth-weight (2.69 kg versus 3.31 kg, p < 0.01), and lower mean weight centiles during interstage follow-up (mean centiles of 3.1 versus 10.8, p < 0.01). CONCLUSION: Survival in the home-monitoring programme is comparable with other home-monitoring programmes in the literature. Hybrid procedure, cardiac dysfunction, sub-optimal weight gain, and Asian ethnicity were significant risk factors for death. Home-monitoring programmes should continue to raise awareness of these factors and seek solutions to mitigate adverse events. Future work to generalise home-monitoring programme and single-ventricle fetus to stage 2 outcomes in the United Kingdom will require multi-centre collaboration.

OBJECTIVE: To study the impact of out-of-hours delivery on outcome for neonates with antenatally diagnosed transposition of the great arteries. SETTING: Tertiary paediatric cardiology centre (Yorkshire, United Kingdom), with co-located tertiary neonatal unit. PATIENTS: Neonates with antenatally diagnosed simple transposition of the great arteries delivered out-of-hours (Monday to Friday 17:00-08:00 and weekends) versus in-hours between 2015 and 2020. OUTCOME: The primary outcome was survival to hospital discharge. Secondary outcomes included neurological morbidity, length of stay, and time to balloon atrial septostomy. RESULTS: Of 51 neonates, 38 (75%) were delivered out-of-hours. All neonates born in the tertiary centre survived to discharge. Time to balloon atrial septostomy was slightly longer for out-of-hours deliveries compared to in-hours (median 130 versus 93 mins, p = 0.33). Neurological morbidity occurred for nine (24%) patients in the out-of-hours group and one (8%) in-hours (OR 3.72, 95% CI: 0.42-32.71, p = 0.24). Length of stay was also similar (18.5 versus 17.3 days, p = 0.59). Antenatal diagnosis of a restrictive atrial septum was associated with a lower initial pH (7.03 versus 7.13; CI: 0.03-0.17, p = 0.01), longer length of stay (22.6 versus 17.3 days; CI: 0.37-10.17, p = 0.04), and increased neurological morbidity (44% versus 14%; OR 4.80, CI 1.00-23.15, p = 0.05). A further three neonates were delivered in surrounding hospitals, with a mortality of 67% (versus 0 in tertiary centre; OR 172, CI 5-5371, p = 0.003). CONCLUSION: Neonates with antenatally diagnosed transposition of the great arteries have similar outcomes when delivered out-of-hours versus in-hours. Antenatal diagnosis of restrictive atrial septum is a significant predictor of worse outcomes. In our region, delivery outside the tertiary cardiac centre had a significantly higher risk of mortality.

Global food systems are developing rapidly, and have resulted in a large burden of disease and a high proportion of environmental resource use. We combined global data sources on food supply and trade, environmental footprints, burdens of disease, and vulnerability to climate change to explore patterns from 1990 to 2017. Four distinct patterns of food supply (animal sources and sugar, vegetables and nuts, starchy roots and fruits, and seafood and oils) were matched to health and environmental risks. The animal sources and sugar pattern was found to have the greatest environmental footprint and to be associated with a greater burden of chronic disease than any other pattern, although it was also associated with lower undernutrition. This pattern is globally predominant, but has begun to decrease in higher income countries. Countries where this pattern is predominant are generally among the least susceptible to climate change, whereas more susceptible countries tend to have more sustainable patterns of food supply. More countries that are susceptible to climate change are increasingly exporting a larger proportion than before of their cereals, fruit, and vegetables globally, which will lead to increased risks in global food security. To increase resilience to future shocks, dietary change towards more sustainable patterns should accelerate in high-income countries, and the food systems of the most susceptible countries should be protected.

RESUMEN
AIMS: Post-infarction ventricular septal defect (PIVSD) is a mechanical complication of acute myocardial infarction (AMI) with a poor prognosis. Surgical repair is the mainstay of treatment, although percutaneous closure is increasingly undertaken. METHODS AND RESUTS: Patients treated with surgical or percutaneous repair of PIVSD (2010-2021) were identified at 16 UK centres. Case note review was undertaken. The primary outcome was long-term mortality. Patient groups were allocated based upon initial management (percutaneous or surgical). Three-hundred sixty-two patients received 416 procedures (131 percutaneous, 231 surgery). 16.1% of percutaneous patients subsequently had surgery. 7.8% of surgical patients subsequently had percutaneous treatment. Times from AMI to treatment were similar [percutaneous 9 (6-14) vs. surgical 9 (4-22) days, P = 0.18]. Surgical patients were more likely to have cardiogenic shock (62.8% vs. 51.9%, P = 0.044). Percutaneous patients were substantially older [72 (64-77) vs. 67 (61-73) years, P < 0.001] and more likely to be discussed in a heart team setting. There was no difference in long-term mortality between patients (61.1% vs. 53.7%, P = 0.17). In-hospital mortality was lower in the surgical group (55.0% vs. 44.2%, P = 0.048) with no difference in mortality after hospital discharge (P = 0.65). Cardiogenic shock [adjusted hazard ratio (aHR) 1.97 (95% confidence interval 1.37-2.84), P < 0.001), percutaneous approach [aHR 1.44 (1.01-2.05), P = 0.042], and number of vessels with coronary artery disease [aHR 1.22 (1.01-1.47), P = 0.043] were independently associated with long-term mortality. CONCLUSION: Surgical and percutaneous repair are viable options for management of PIVSD. There was no difference in post-discharge long-term mortality between patients, although in-hospital mortality was lower for surgery.

OBJECTIVES: Since percutaneous pulmonary valve implantation (PPVI) was introduced to prolong the lifetime of surgically placed right ventricular to pulmonary artery conduits, valve technology has evolved and the indications for PPVI expanded to native and larger right ventricular outflow tracts. We explore how indications, patient populations and outcomes compare to surgical pulmonary valve replacement (PVR). METHODS: This is a retrospective cohort study of PPVI and PVR procedures between 1998 and 2020 at a single UK centre. One hundred and twenty-eight patients underwent PPVI and 365 patients PVR. Primary outcome measures were survival, infective endocarditis and reintervention. RESULTS: The most common indication for PVR was replacement of the native pulmonary valve for pulmonary regurgitation whereas PPVI was more commonly used to treat pulmonary stenosis in a previously placed bioprosthetic conduit or valve. Treatment indications for PPVI expanded over the study to include the native right ventricular outflow tract. Survival was similar for PPVI and PVR (92% PPVI and 96.8% PVR at 5 years; 85.8% PPVI and 95.1% PVR at 10 years). Preprocedural New York Heart Association class 3 and 4 was the most important predictor of poor outcome. Annualized infective endocarditis rate was significantly higher for the Melody PPVI (0.024 vs 0.0024/person/year for PVR, P < 0.05). Both groups showed significant symptomatic improvement postprocedure with remodelling of ventricular volumes and improvement in cardiac output. Long-term follow-up for PVR showed half of patients will need replacement at 10-15 years post-index procedure. CONCLUSIONS: An increasing number of patients requiring PVR can now be treated percutaneously. A lifetime strategy for re-valving should be considered at the first valve implant.

Infants with complex cyanotic CHD can become symptomatic from insufficient pulmonary blood supply following either ductal closure or due to outflow tract obstruction. Blalock-Taussig shunt mortality remains significant and recent studies have highlighted the advantages of using transcatheter alternatives. We present here our experience in changing our primary choice of palliation from the Blalock-Taussig shunt to transcatheter palliation with either a ductal stent or, if antegrade flow is present, a right ventricular outflow tract stent.This is a retrospective, single-unit cohort study. Eighty-seven infants underwent palliation for insufficient pulmonary blood flow at under 3 months of age between 2012 and 2019. On an intention-to-treat basis, 29 underwent insertion of a Blalock-Taussig shunt, 36 duct stents, and 22 right ventricular outflow tract stents at median ages of 15, 9, and 32 days, respectively, and median weights of 3.3, 3.1, and 3.1 kg, respectively. No primary Blalock-Taussig shunts have been performed in our institution since 2017.At 30-days there had been one death in each group (univariable p = 0.93) and deaths prior to repair totalled three in the shunt group, four in the ductal stent group, and two in the right ventricular outflow tract stent group (univariable p = 0.93). Reintervention on the pulmonary circuit prior to next stage of surgery was more frequent in those undergoing transcatheter intervention, reaching statistical significance by logrank (p = 0.012).In conclusion, within this work we provide further evidence of the safety and efficacy of transition from a primary surgical to primary transcatheter palliation pathway in infants with insufficient pulmonary blood supply.

BACKGROUND: No established risk prediction tool exists in United Kingdom and Irish Paediatric Cardiology practice for patients undergoing cardiac catheterisation. The Catheterisation RISk score for Paediatrics is used primarily in North American practice to assess risk prior to cardiac catheterisation. Validating the utility and transferability of such a tool in practice provides the opportunity to employ an already established risk assessment tool in everyday practice. AIMS: To ascertain whether the Catheterisation RISk score for Paediatrics assessment tool can accurately predict complications within United Kingdom and Irish congenital catheterisation practice. METHODS: Clinical and procedural data including National Institute for Cardiovascular Outcomes Research derived outcome data from 1500 patients across five large congenital cardiology centres in the United Kingdom and Ireland were retrospectively collected. Catheterisation RISk score for Paediatrics were then calculated for each case and compared with the observed procedural outcomes. Chi-square analysis was used to determine the relationship between observed and predicted events. RESULTS: Ninety-eight (6.6%) patients in this study experienced a significant complication as qualified by National Institute for Cardiovascular Outcomes Research classification. 4% experienced a moderate complication, 2.3% experienced a major complication and 0.3% experienced a catastrophic complication resulting in death. Calculated Catheterisation RISk score for Paediatrics scores correlated well with all observed adverse events for paediatric patients across all CRISP categories. The association was also transferable to adult congenital heart disease patients in lower Catheterisation RISk score for Paediatrics categories (CRISP 1-3). CONCLUSION: The Catheterisation RISk score for Paediatrics score accurately predicts significant complications in congenital catheterisation practice in the United Kingdom and Ireland. Our data validated the Catheterisation RISk score for Paediatrics assessment tool in five congenital centres using National Institute for Cardiovascular Outcomes Research-derived outcome data.
