The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery (WCPCCS) will be held in Washington DC, USA, from Saturday, 26 August, 2023 to Friday, 1 September, 2023, inclusive. The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery will be the largest and most comprehensive scientific meeting dedicated to paediatric and congenital cardiac care ever held. At the time of the writing of this manuscript, The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery has 5,037 registered attendees (and rising) from 117 countries, a truly diverse and international faculty of over 925 individuals from 89 countries, over 2,000 individual abstracts and poster presenters from 101 countries, and a Best Abstract Competition featuring 153 oral abstracts from 34 countries. For information about the Eighth World Congress of Pediatric Cardiology and Cardiac Surgery, please visit the following website: [www.WCPCCS2023.org]. The purpose of this manuscript is to review the activities related to global health and advocacy that will occur at the Eighth World Congress of Pediatric Cardiology and Cardiac Surgery.
Acknowledging the need for urgent change, we wanted to take the opportunity to bring a common voice to the global community and issue the Washington DC WCPCCS Call to Action on Addressing the Global Burden of Pediatric and Congenital Heart Diseases. A copy of this Washington DC WCPCCS Call to Action is provided in the Appendix of this manuscript. This Washington DC WCPCCS Call to Action is an initiative aimed at increasing awareness of the global burden, promoting the development of sustainable care systems, and improving access to high quality and equitable healthcare for children with heart disease as well as adults with congenital heart disease worldwide.
Infants undergoing stage 1 palliation for hypoplastic left heart syndrome may have post-operative feeding difficulties. Although the cause of feeding difficulties in these patients is multi-factorial, residual arch obstruction may affect gut perfusion, contributing to feeding intolerance. We hypothesised that undergoing arch reintervention following stage 1 palliation would be associated with post-operative feeding difficulties.
This was a retrospective cohort study. We analysed data from the National Pediatric Cardiology Quality Improvement Collaborative, which maintains a multicentre registry for infants with hypoplastic left heart syndrome discharged home following stage 1 palliation. Patients who underwent arch reintervention (percutaneous or surgical) prior to discharge following stage 1 palliation were compared with those who underwent non-aortic arch interventions after stage 1 palliation and those who underwent no intervention. Median post-operative days to full enteral feeds and weight for age z-scores were compared. Predictors of post-operative days to full feeds were identified.
Among patients who underwent arch reintervention, post-operative days to full enteral feeds were greater than for those who underwent non-aortic arch interventions (25 versus 16, p = 0.003) or no intervention (median days 25 versus 12, p < 0.001). Arch intervention, multiple interventions, gestational age, and the presence of a gastrointestinal anomaly were predictors of days to full feeds.
Repeat arch intervention is associated with a longer time to achieve full enteral feeding in patients with hypoplastic left heart syndrome after stage 1 palliation. Further investigation of this association is needed to understand the role of arch obstruction in feeding problems in these patients.
