The paediatric post-cardiac catheterisation Wrap (Wrap), an innovative medical safety device, swaddles young paediatric patients in a supine position aiding in immobilisation post-cardiac catheterisation. This pilot study investigated the feasibility and safety of using the Wrap on young paediatric patients during their bed rest period following cardiac catheterisation with femoral access.

Boston Children’s Hospital Cardiac Catheterization Lab.

20 patients, ages 1–5 years and weighing 3–25 kg.

Investigator-developed tools used to collect data included the Demographic and Outcome Measures Data Tool, the Parent/Caregiver Satisfaction, and Provider Ease of Use tools. They measured:

1. 1. The feasibility of using the Wrap

2. 2. Wrap ease of use from the nurse providers’ perspective

3. 3. Parent satisfaction related to the Wrap

4. 4. Frequency of Wrap non-bleeding-related adverse events

5. 5. Frequency of rebleeding at femoral groin access sites

The Wrap was feasible and safe; increased nurse provider satisfaction by allowing visualisation of the groin access sites while minimising the need for hands-on care; and increased parent satisfaction by allowing parents to hold and provide comfort while their child was on bed rest.

The Wrap is a safe alternative to the current practice of swaddling with a bath blanket. Further studies are warranted to assess the Wrap’s effectiveness in reducing the incidence of rebleeding events in the post-cardiac catheterisation period and explore clinical use outside of the Cardiac Catheterization Lab.

Neurodevelopmental challenges are the most prevalent comorbidity associated with a diagnosis of critical CHD, and there is a high incidence of gross and fine motor delays noted in early infancy. The frequency of motor delays in hospitalised infants with critical CHD requires close monitoring from developmental therapies (physical therapists, occupational therapists, and speech-language pathologists) to optimise motor development. Currently, minimal literature defines developmental therapists’ role in caring for infants with critical CHD in intensive or acute care hospital units.

This article describes typical infant motor skill development, how the hospital environment and events surrounding early cardiac surgical interventions impact those skills, and how developmental therapists support motor skill acquisition in infants with critical CHD. Recommendations for healthcare professionals and those who provide medical or developmental support in promotion of optimal motor skill development in hospitalised infants with critical CHD are discussed.

Infants with critical CHD requiring neonatal surgical intervention experience interrupted motor skill interactions and developmental trajectories. As part of the interdisciplinary team working in intensive and acute care settings, developmental therapists assess, guide motor intervention, promote optimal motor skill acquisition, and support the infant’s overall development.

Cyanotic CHD is a life-threatening condition that presents with low oxygen saturation in the newborn period. Hypoxemia might cause alterations in the metabolic pathways. In the present study, we aimed to evaluate the early postnatal amino acid and carnitine/acylcarnitine profiles of newborn infants with cyanotic CHD.

A single centre case-control study was conducted. Twenty-seven patients with cyanotic CHD and 54 healthy newborn controls were enrolled. As part of the neonatal screening programme, results of amino acid and carnitine/acylcarnitine were recorded and compared between groups.

Twenty-seven neonates with cyanotic CHD and 54 healthy newborns as controls were enrolled in the study. Cyanotic CHD neonates had higher levels of alanine, phenylalanine, leucine/isoleucine, citrulline, ornithine, C5, C5-OH; but lower levels of C3, C10, C12, C14, C14:1, C16, C16.1, C18, C5-DC, C6-DC, C16-OH, C16:1-OH when compared with the healthy controls.

This study showed that there are differences between patients with cyanotic CHD and healthy controls in terms of postnatal amino acid and carnitine/acylcarnitine profiles.

This study investigates the hygiene standards in the context of the COVID-19 pandemic and their impact on the perioperative incidence of human metapneumovirus as well as the typical symptom burden of human metapneumovirus-infected children with CHDs.

Between March 2018 and July 2021, all patients of a cardiac paediatric ICU of a German university hospital were included in this retrospective cohort analysis.

A total of 589 patients with CHD were included in the analysis. Three hundred and fifty-two patients (148 females and 204 males) were admitted before the introduction of social distancing and face masks between March 2018 and 15 April 2020 (cohort A). Two hundred and thirty-seven patients (118 females and 119 males) were admitted after the introduction between April 16 and July 2021 (cohort B). In cohort A, human metapneumovirus was detected in 11 out of 352 patients (3.1%) during their stay at cardiac paediatric ICU. In cohort B, one patient out of 237 (0.4%) tested positive for human metapneumovirus. Patients who tested positive for human metapneumovirus stayed in cardiac paediatric ICU for a median of 17.5 days (range, 2–45 days). Patients without a detected human metapneumovirus infection stayed in the cardiac paediatric ICU for a median of 4 days (range, 0.5–114 days). Nine out of 12 (75%) human metapneumovirus-positive patients showed atelectasis.

Perioperative human metapneumovirus infections prolong cardiac paediatric ICU stay in children with CHD. In affected patients, pulmonary impairment with typical symptoms appears. Under certain circumstances, a complication-rich perioperative infection with human metapneumovirus could be prevented in paediatric cardiac high-risk patients by prophylactic hygiene intervention.

Long hospital stays for neonates following cardiac surgery can be detrimental to short- and long-term outcomes. Furthermore, it can impact resource allocation within heart centres' daily operations. We aimed to explore multiple clinical variables and complications that can influence and predict the post-operative hospital length of stay.

We conducted a retrospective observational review of the full-term neonates (<30 days old) who had cardiac surgery in a tertiary paediatric cardiac surgery centre – assessment of multiple clinical variables and their association with post-operative hospital length of stay.

A total of 273 neonates were screened with a mortality rate of 8%. The survivors (number = 251) were analysed; 83% had at least one complication. The median post-operative hospital length of stay was 19.5 days (interquartile range 10.5, 31.6 days). The median post-operative hospital length of stay was significantly different among patients with complications (21.5 days, 10.5, 34.6 days) versus the no-complication group (14 days, 9.6, 19.5 days), p < 0.01. Among the non-modifiable variables, gastrostomy, tracheostomy, syndromes, and single ventricle physiology are significantly associated with longer post-operative hospital length of stay. Among the modifiable variables, deep vein thrombosis and cardiac arrest were associated with extended post-operative hospital length of stay.

Complications following cardiac surgery can be associated with longer hospital stay. Some complications are modifiable. Deep vein thrombosis and cardiac arrest are among the complications that were associated with longer hospital stay and offer a direct opportunity for prevention which may be reflected in better outcomes and shorter hospital stay.

Published guidelines for sports restriction for children with a bicuspid aortic valve remain controversial. We sought to describe practice variation and factors influencing sports restrictions in these children.

This retrospective single-centre study included children (7–18 years old) with an isolated bicuspid aortic valve at baseline from 1 January, 2005 to 31 December, 2014. Sports restrictions, factors potentially influencing decision-making, and outcomes were collected. Descriptive statistics and multivariable mixed-effects logistic regression models were performed with providers and patients as random effects. Provider variation was estimated using intraclass correlation coefficients. Odds ratios, 95% confidence intervals, and p-values were reported from the models.

In 565 encounters (253 children; 34 providers), 41% recommended no sports restrictions, 40% recommended high-static and high-dynamic restrictions, and 19% had no documented recommendations. Based on published guidelines, 22% of children were inappropriately restricted while 30% were not appropriately restricted. The paediatric cardiology provider contributed to 37% of observed practice variation (p < 0.001). Sports restriction was associated with older age, males, greater ascending aorta z-score, and shorter follow-up interval. There were no aortic dissections or deaths and one cardiac intervention.

Physicians frequently fail to document sports restrictions for children with a bicuspid aortic valve, and documented recommendations often conflict with published guidelines. Despite this, no adverse outcomes occurred. Providers accounted for a significant proportion of the variation in sports restrictions. Further research to provide evidence-based guidelines may improve provider compliance with activity recommendations in this population.

Pulmonary insufficiency requiring reintervention frequently occurs after primary tetralogy of Fallot repair. Repeat interventions present a challenge for both the surgeon and patient. We compare a minimally invasive, 5 cm left anterior mini-incision to redo median sternotomy for pulmonary valve replacement in tetralogy of Fallot patients.

Following Internal Review Board approval, we conducted a single institution retrospective review of patients with tetralogy of Fallot who underwent pulmonary valve replacement via redo median sternotomy or left anterior mini-incision between 13 July, 2016 and 6 March, 2020.

Twenty-three patients underwent pulmonary valve replacement following primary tetralogy of Fallot repair between March 2016 and March 2020. Twelve patients received a redo-median sternotomy from March 2016 to August 2018. Left anterior mini-incision was first offered in August of 2018 and was chosen by all eleven patients thereafter. The two groups had similar baseline characteristics including preoperative pulmonary valve dysfunction. Early trends suggest a longer cardiopulmonary bypass time for patients who received left anterior mini-incisions. Other outcomes were comparable, including operative times, blood product requirements, residual pulmonary valve dysfunction, postoperative pain, narcotic requirements, ICU length of stay, total length of stay, and postoperative complications.

In patients who have previously undergone primary repairs of tetralogy of Fallot, outcomes for pulmonary valve replacement via left anterior mini-incision are comparable to those via redo median sternotomy.

To avoid rhythm disturbance, sutures for ventricular septal defect closure have been traditionally placed 2∼5 mm or more away from the edge of the ventricular septal defect. However, the traditional suturing method appears to induce right bundle branch block and tricuspid valve regurgitation after ventricular septal defect closure more than our alternative technique, shallow suturing just at the edge of the ventricular septal defect (shallower bites at the postero-inferior margin). We aimed to verify our clinical experience of perimembranous ventricular septal defect repair.

The alternative shallow suturing method has been applied since 2003 at our institution. We retrospectively reviewed the clinical data of 556 isolated perimembranous ventricular septal defect patients who underwent surgical closure from 2000 to 2019. We investigated the postoperative occurrence of right bundle branch block or progression of tricuspid regurgitation and analysed risk factors for right bundle branch block and tricuspid regurgitation.

Traditional suturing method (Group T) was used in 374 cases (66.8%), and alternative suturing method (Group A) was used in 186 cases (33.2%). The right bundle branch block occurred more frequently in Group T (39.6%) than in Group A (14.9%). In multivariable logistic regression analysis, Group T and patch material were significant risk factors for late right bundle branch block. More patients with progression of tricuspid regurgitation were found in Group T.

Shallow suturing just at the edge of the ventricular septal defect may reduce the rate of right bundle branch block occurrence and tricuspid regurgitation progression without other complications.

Infradiaphragmatic partial anomalous pulmonary venous connection is occasionally diagnosed in adulthood. Management of infradiaphragmatic PAPVC depends on anatomy and clinical presentation.

Over a 10-year period, we observed seven adult patients (median age 29 years) with partial anomalous pulmonary venous connection. We classified our patients in two groups. Group I: isolated partial anomalous pulmonary venous connection from one pulmonary lobe to the inferior vena cava, three patients. Group II: partial anomalous pulmonary venous connection of the entire right lung to IVC, four patients.

The mean term follow-up was 5.4 years. Patients in Group I have been managed conservatively, as they were asymptomatic, without a significant shunt. Patients in Group II were surgically corrected using long right intra-atrial baffles. After 6 months of follow-up, the first two cases were diagnosed with complete tunnel thrombosis and loss of right lung function. Oral anticoagulation failed to recanalize the tunnel. Considering this serious complication, the other two patients were empirically and preventively treated with anticoagulation after surgery, with good outcome on long-term follow-up.

Conservative management should be considered for asymptomatic patients, without a significant shunt. Surgical treatment of infradiaphragmatic partial anomalous pulmonary venous connection of the entire right lung in inferior vena cava is challenging. Slow blood flow inside the long intra-atrial baffles inclines to thrombosis and occlusion, as we observed in two cases. Therefore, oral anticoagulation should be considered for long baffles with slow blood flow.

Neonatal enteroviral myocarditis is a rare but potentially fatal illness. We sought to identify echocardiographic markers at diagnosis that could help risk-stratify infants for poor outcome and to characterise late sequelae.

We reviewed data for infants <30 days of age diagnosed with enteroviral myocarditis between 1999 and 2019 at Children’s Wisconsin. Echo measures were collected retrospectively from the initial neonatal study including left ventricular ejection fraction, shortening fraction, diastolic and systolic dimensions, and peak global circumferential and longitudinal strain.

Fourteen neonates were diagnosed at an average age of 11 days. All had abnormal left ventricular ejection fraction (mean 38%; range 22–53%) at diagnosis. Three infants died, and one required transplantation during initial hospital. The 10 transplant-free survivors had significantly better global circumferential strain and global longitudinal strain at the initial echo compared to the 4 who died or needed transplant (global circumferential strain −13.2% versus −6.8%, p = 0.005; global longitudinal strain −8.8% versus −4.7%, p = 0.016). All other measures of left ventricular systolic function/dimensions were similar between the two groups. Follow-up data were available for 8/10 survivors; 5/8 had a persistently abnormal echo at an average interval of 8.3 years. 4/8 developed a left ventricular aneurysm that was consistently localised to the posterior basal wall.

Neonatal enteroviral myocarditis carries a high risk of early mortality and late morbidity. Echo-derived left ventricular strain measures have utility in risk stratifying infants with enteroviral myocarditis. Most survivors continue to have late dysfunction necessitating cardiology surveillance and medical therapy.

We aimed to discuss our unit’s experience performing left ventriculotomies on children.

Between 2000 and 2022, we identified paediatric patients who required left ventriculotomy. Relevant information was gathered retrospectively.

There were eight patients who underwent surgical procedure including left ventriculotomy. The range of weight and age was between 4.5 and 50 kg and 5 months to 17 years, respectively. Left ventriculotomy was primarily performed for the excision of cardiac masses in all but one who had pseudoaneurysm repair. There were no deaths that occurred early or late. Pre-operative and post-operative ejection fractions and fractional shortening values were comparable. There was no arrhythmia detected post-operatively.

We conclude that an apical left ventriculotomy does not compromise the function of the left ventricle, even in young infants. In selected patients, it may be used safely for surgical access to the left ventricle.
