Objective: Neurodevelopmental follow-up programmes for children with CHD help identify neurodevelopmental impairments and support the delivery of recommended interventions. The Cardiac Neurodevelopmental Outcome Collaborative, Diversity, Equity, and Inclusion Special Interest Group surveyed members to assess perceived patient barriers to neurodevelopmental follow-up, previous diversity and inclusion education, and confidence in caring for historically marginalised populations.

Methods: A link to a Redcap online survey was emailed to Cardiac Neurodevelopmental Outcome Collaborative members on 23 April 2022, with 4 weeks given to complete.

Results: Eighty-four participants from 37 institutions in North America completed the survey. Respondents acknowledged that education on the importance of neurodevelopmental follow-up and frequent accommodations for cancellations or rescheduling clinic visits is essential. Language interpretation and written materials were available in languages other than English, but a limited number provided fully translated evaluation reports. Driving distance and the caregiver's lack of understanding of the rationale for neurodevelopmental follow-up were the top perceived barriers to programme attendance. At the institutional level, training for cultural competency was typically provided, and most respondents felt comfortable caring for patients from diverse backgrounds. However, many agreed their programmes could do more to make evaluations accessible to historically marginalised/underserved populations.

Conclusions: Multiple barriers exist to cardiac neurodevelopmental follow-up, particularly for patients from under-represented minorities and for those whose primary language is not English. Surveying families will be valuable to understand how we may overcome these barriers. Further education about the importance of neurodevelopmental follow-up programmes continues to be essential.

Pulmonary vasodilators increased the systemic-to-pulmonary collateral flow in two single-ventricle cases, causing haemodynamic decline. Discontinuation reversed the collateral flow and improved heart failure, highlighting the need for careful monitoring. Serial cardiac MRI, as a non-invasive tool, may be essential to detect changes in collateral flow and guide vasodilator use for optimal management in this population.

In isolated subclavian artery, abnormal aortic arch development causes a loss of continuity with the aorta. Patent ductus arteriosus is a known cause of congestive heart failure. Herein, we present a rare case of congestive heart failure caused by isolated right subclavian artery and right patent ductus arteriosus associated with left-sided aortic arch treated by early closure.

Pulmonary arteriovenous malformations are abnormal vascular connections between pulmonary arteries and veins, often causing right-to-left shunting. In this report, a 4-year-old boy with low oxygen saturation was diagnosed with a large, complex pulmonary arteriovenous malformation involving four feeding arteries. Percutaneous transcatheter closure was performed using four devices to occlude the major feeding arteries, resulting in increased arterial oxygen saturation from 72 to 98%. This report depicts the successful use of multiple devices for percutaneous closure of a complex pulmonary arteriovenous malformation in a child and highlights the minimally invasive and effective nature of this approach.

Background: Acquired chylothorax is an established complication of CHD surgery, affecting 2-9% of patients. CHD places a child at risk for failure to thrive, with subsequent chylothorax imposing additional risk.

Objective: We conducted a retrospective chart review to ascertain quantitative markers of nutrition and growth in children affected by chylothorax following CHD surgery between 2018 and 2022 compared to controls.

Methods: We utilised electronic medical record system, EPIC, at Children's Hospital, New Orleans, targeting subjects < 18 years old who underwent CHD surgery between 2018 and 2022 and developed a subsequent chylothorax. Study subjects were identified using the 10th revision of the International Classification of Diseases codes (ICD-10 codes: J94.0, I89.8, and J90.0). Each chylothorax case (n = 20) was matched by procedure type and age to a control with no chylothorax (n = 20). Data were recorded in REDCap and analysed using SPSS.

Results: After removal of outliers, we analysed 19 total matched pairs. There was no statistical difference in growth velocity (p = 0.12), weight change (operation to discharge) (p = 0.95), weight change (admission to discharge) (p = 0.35), Z-score change (operation to discharge) (p = 0.90), Z-score change (admission to discharge) (p = 0.21), serum protein (p = 0.88), or serum albumin (p = 0.82). Among cases, linear regression demonstrated no significant association between maximum chylous output and growth velocity (p = 0.91), weight change (operation to discharge) (p = 0.15), or weight change (admission to discharge) (p = 0.98).

Conclusions: We did not observe statistically significant markers of growth or nutrition in children with chylothorax post-CHD surgery compared to those without chylothorax. Multisite data collection and analysis is required to better ascertain clinical impact and guide clinical practice.

Background: When anomalous left coronary artery from the pulmonary artery is diagnosed in infancy, it is associated with high mortality, but collaterals permit rare adult survival despite coronary steal. We report normalisation of perfusion abnormality after transcatheter proximal left coronary occlusion in a symptomatic adult with inducible ischaemia.

Methods: A forty-eight-year-old female presented with exertional chest pain; EKG showed sinus rhythm with left axis deviation with intraventricular conduction defect. Echocardiogram diagnosed an anomalous left coronary artery arising from the pulmonary artery with normal ventricular function which was further confirmed by CT. The case was discussed with the surgical team, and it was decided to surgically ligate. The patient did not give consent for the surgical procedure; the patient was taken up for the procedure.

Results: Device was released safely after confirming the position on echocardiogram after the procedure showed improvement in intraventricular conduction defect and QTc duration, and also no significant ischaemic changes were noted. Myocardial perfusion scintigraphy was done after 6 months of procedure which showed improvement in contractile function and perfusion of left ventricle.

Conclusions: Device closure in long-standing anomalous left coronary artery from pulmonary artery case is safe, and long-term follow-up is needed.

Introduction: The treatment for proximal aortic arch hypoplasia in paediatric patients is still controversial. While some authors favours direct tissue anastomosis, others state that patch augmentation may also be a good alternative. The aim of this study is to compare the results of arch reconstructions using bovine pericardium with the direct anastomosis technique.

Materials and method: Paediatric patients who underwent arch reconstruction via median sternotomy between 2019 and 2023 were evaluated. Patients were divided into two groups according to the repair method of arch reconstructions: direct native tissue anastomosis and bovine pericardial patch augmentation. Using perioperative data, the relationship between the surgical method and postoperative morbidity, in-hospital mortality, and the risks for early reintervention was investigated.

Results: Between August 2019 and August 2023, 38 paediatric patients underwent arch reconstruction. The average age and weight of the patients were 40 days (15-157.5 days, interquartile) and 3.78 kg (3.2-6.0 kg, interquartile range), respectively. While completely native tissue anastomosis was applied in 18 of the patients (47.4%), bovine pericardial patch was used in arch reconstruction in 20 patients (52.6%). Cross-clamp time was found to be significantly longer in patients using bovine patches (p = .016). No difference was detected between the two surgical methods in terms of postoperative mortality and morbidity factors (p > .05). There was no significant difference between the two surgical procedures in terms of reintervention in the early period after discharge (p = .177).

Conclusion: Although early results of both reconstruction techniques may be promising, their reliability needs to be evaluated in detail with large-scale prospective studies.

Background: We aimed to evaluate the clinical and laboratory characteristics and aetiological factors of patients who underwent pericardiocentesis for moderate to large pericardial effusion.

Method: A total of 38 patients who underwent pericardiocentesis due to moderate-severe pericardial effusion and not related to cardiac surgery were included in the study.

Results: The male-to-female ratio was 2.16, and found to be 7.5 in patients over 3 years of age. Mean age and body weight of the patients were 69.4 ± 74.9 months and 22.5 ± 22.4 kg. Dyspnoea (51.7%) was the most common complaint, followed by chest pain (37.9%). Tamponade was present in 23.7% of the patients. The largest diameter of effusion was 24.4 ± 10.4 mm. The amount of fluid drained was 279.24 ± 279 ml. Macroscopic appearance was serous in 12 (34.3%), and haemorrhagic in 18 (51.4%). No complication related to procedure was seen. Aetiology for efusion was infectious in 26%, idiopathic in 18%, iatrogenic in 11%, rheumatological in 11%, malignancy in 8%, cardiomyopathy in 8%, and other factors related in 18%. Of the 38 patients, 16 received nonsteroidal anti-inflammatory drugs (NSAID), and colchicine and corticostreoid were added in nine and two patients, respectively. A total of eight (21%) patients died during follow-up.

Conclusion: In conclusion, percutaneous pericardiocentesis can be applied safely and the underlying aetiology is decisive in the prognosis of the patient. Although pericardial effusion in children is often due to inflammation of the pericardium, it can develop as a finding of many local or systemic diseases that should be kept in mind.

Introduction: Data on arterial thromboembolism in children undergoing cardiac surgery are limited. We sought to characterise, and estimate rates of, incident and recurrent arterial thromboembolism, and describe antithrombotic therapies for treatment in a large multinational population of children with CHD undergoing cardiac surgery.

Methods: We queried the TriNetX global electronic health record (derived real-world data research platform) from 2017 to 2024 for patients less than 18 years of age and an index arterial thromboembolism within 1 year of congenital cardiac surgery. Data were descriptively analysed.

Results: Of 20,102 children who underwent an index cardiac surgery for CHD, 206 (1.1%) developed an index arterial thromboembolism within 1 year of surgery: 111 (53.9%) had only arterial thromboembolism and 95 (46.1%) had concomitant venous thromboembolism. The most common anatomic site for arterial thromboembolism was the lower extremity (n = 141, 68.4%), and the most common surgery was the Glenn procedure (n = 35, 17%). Unfractionated heparin was utilised in 136 (67 %) and aspirin in 91 (44.2%) patients. Recurrent thromboembolism occurred in 36 (17.5%) patients within 1 year of the index thromboembolism.

Conclusions: Among children undergoing congenital cardiac surgery, arterial thromboembolism was rare (1% of patients), but the 1-year risk of recurrent thromboembolism was high, at 17.5%. Multicentre prospective cohort studies are warranted to further evaluate risk factors for recurrent thromboembolism, to facilitate future risk-stratified interventional trials designed to reduce the high thromboembolism recurrence risk in these children.
