Polymorphic Variants

<p><strong>Background.</strong> Cardiac surgery in combination with hypothermia, ischaemia and reperfusion leads to an inflammatory response causing postoperative complications. Toll-like receptors are signalling molecules through which some functions of innate immunity can be activated, and polymorphic variants in the TLR-family genes can be predictors of complications after cardiac surgery.<br /><strong>Aim.</strong> To study the associations of TLR-family genes with infectious and non-infectious complications of cardiac surgery for congenital heart defects.<br /><strong>Methods.</strong> The study included 89 children (44 girls and 45 boys) with congenital heart defects who underwent cardiac surgery. Complications occurred in 47 children 47 days after cardiac surgery. There were no complications in 42 children. Genotyping was performed by real-time PCR using TaqMan probes.<br /><strong>Results.</strong> A two-locus model of gene-gene interaction between <em>TLR1</em> rs5743551 and <em>TLR2</em> rs3804099 was the best fit, accounting for 4.01% of phenotypic entropy. The <em>TLR2</em> gene polymorphic variant rs5743708 had the highest predictive potential (2.59%).<br /><strong>Conclusion.</strong> The development of postoperative complications of cardiac surgical treatment for congenital heart defects can be due to the synergistic effect of the polymorphic variants rs5743551 in the <em>TLR1</em> gene and rs3804099 in the <em>TLR2</em> gene. This effect occurs through the features of <em>TLR1</em> and <em>TLR2</em> transcription, the subsequent expression of receptors on cells and signalling which activates the synthesis of proinflammatory cytokines and chemokines.</p><p>Received 25 February 2021.

Paediatric Cardiology

Paediatric cardiology is a subspecialty ideally suited to telemedicine. A small number of experts cover large geographical areas and the diagnosis of congenital heart defects is largely dependent on the interpretation of medical imaging. Telemedicine has been applied to a number of areas within paediatric cardiology. However, its widespread uptake has been slow and fragmentary. In this chapter the authors examine the current evidence pertaining to telemedicine applied to paediatric cardiology, including their own experience, the importance of research and, in particular, economic evaluation in furthering telemedicine endeavours. Perhaps most importantly, they discuss the issues relating transitioning a pilot project into a sustainable clinical service.

Neurodevelopmental Outcomes

Abstract Background Compared with those born at term gestation, infants with complex congenital heart defects (CCHD) who were delivered before 37 weeks of gestational age and received neonatal open cardiac surgery (OHS) have poorer neurodevelopmental outcomes in early childhood. Specific details related to the neurodevelopmental outcome of these infants remain unpublished. Objectives To describe the growth, disability, functional, and neurodevelopmental outcome in early childhood of preterm infants (born at &lt;37+0 weeks gestation) with CCHD and neonatal OHS. Design/Methods We studied all infants with CCHD who received OHS within 6 weeks of corrected age between 1996 and 2016. In the Western Canadian Complex Pediatric Therapies Follow-up Program, comprehensive neurodevelopmental assessments at a corrected age of 18-24 months were done by multidisciplinary teams at the original referral sites. In addition to demographic and clinical data, standardized age-appropriate outcome measures included physical growth with calculated Z-scores, disabilities including cerebral palsy, visual impairment, sensorineural hearing loss; adaptive function (Adaptive Behavioural Assessment System-II); and cognitive, language, and motor skills (Bayley Scales of Infant and Toddler Development-III). Results From 1996 to 2016, 115 preterm infants (34±2 weeks gestation, 2339±637g, 64% males) with CCHD had OHS with 11(10%) deaths before first discharge and 21 (18%) by 2 years. Prior to the first surgery, 7 (6%) neonates had cerebral injuries. Overall, 7 had necrotizing enterocolitis; none had retinopathy of prematurity. All 94 surviving infants received comprehensive evaluation at 2 years corrected age; Eighteen (19%) had congenital syndromes who had worse functional and neurodevelopmental outcomes compared to those (n=76) without syndromal abnormalities (SA) (Table). Conclusion For preterm neonates with CCHD and early OHS, the mortality was significant, but the short-term neonatal morbidity was not increased. Compared with published preterm outcomes, the early outcome suggests more cerebral palsy but not sensorineural hearing loss, and greater neurodevelopmental delay. This information is important for management care of the infants, parental counselling and the decision-making process.

Innovative Techniques

The evolution of cardiac surgery has led to increasing emphasis on complete repair of congenital heart defects early in life, nowadays increasingly performed in neonates or small infants. Good results have been achieved because of innovative techniques permitting reconstruction of normal anatomy, and restoration of normal physiology, before either the heart or the patient undergo deleterious adaptation to the congenitally abnormal physiology. Despite the ability surgically to correct complex defects in such small patients, limitations in outcome are sometimes encountered related to the systems necessary for repair. In particular, exposure to cardiopulmonary bypass may present the greatest challenge for these tiny patients.
