- Objective: The objective of this study was to measure the level of empowerment and identify its correlates in young persons with congenital heart disease. Study design: Patients aged 14–18 years with congenital heart disease, and under active follow-up in one of four paediatric cardiology centres in Sweden were invited to participate in a cross-sectional study. A total of 202 young persons returned the questionnaires. Patient empowerment was measured with the Gothenburg Young Persons Empowerment Scale that allows the calculation of total and subscale scores. Univariate and multivariate linear regression analyses were undertaken to analyse possible correlates, including: sex, age, health behaviours, knowledge of congenital heart disease, quality of life, patient-reported health, congenital heart disease complexity, transition readiness and illness perception. Results: The mean empowerment score was 54.6±10.6 (scale of 15–75). Univariate analyses showed that empowerment was associated with age, quality of life, transition readiness, illness perception, health behaviours and patient-reported health (perceived physical appearance, treatment anxiety, cognitive problems and communication issues). However, multivariable linear regression analyses identified that only transition readiness (β=0.28, P<0.001) and communication (β=0.36, P<0.001) had a positive association with patient empowerment. These variables were also significantly associated with the subscale scores of the empowerment scale of knowledge and understanding (P<0.001), shared decision-making (P<0.001) and enabling others (P<0.01). The overall models’ explained variance ranged from 8% to 37%. Conclusion: Patient empowerment was associated with transition readiness and fewer problems communicating. While it is not possible to establish the directionality of the associations, interventions looking to increase empowerment could benefit from using these variables (or measurements) for evaluation purposes.

- Theoretical literature and cross-sectional studies suggest empowerment is associated with other patient-reported outcomes (PROs). However, it is not known if patient empowerment is leading to improvements in other PROs or vice versa.The present study aimed to examine the direction of effects between patient empowerment and PROs in young persons with congenital heart disease (CHD).As part of the STEPSTONES-CHD trial, adolescents with CHD from seven pediatric cardiology centers in Sweden were included in a longitudinal observational study (n = 132). Data were collected when patients were 16 (T0), 17 (T1) and 18 ½ years old (T2). The Gothenburg Young Persons Empowerment Scale (GYPES) was used to measure patient empowerment. Random intercepts cross-lagged panel models between patient empowerment and PROs (communication skills; patient-reported health; quality of life; and transition readiness) were undertaken.We found a significant cross-lagged effect of transition readiness over patient empowerment between T1 and T2, signifying that a higher level of transition readiness predicted a higher level of patient empowerment. No other significant cross-lagged relationships were found.Feeling confident before the transition to adult care is necessary before young persons with CHD can feel in control to manage their health and their lives. Clinicians interested in improving patient empowerment during the transitional period should consider targeting transition readiness.

- The technique in Fontan surgery has developed from the lateral tunnel (LT) toward the extracardiac conduit (EC) used to reduce long-term complications such as atrial arrhythmia and sinus node dysfunction. Heart rate variability (HRV) examines cardiac nervous activity controlling the sinus node. This study aimed to investigate HRV in a cohort of children with univentricular hearts, focusing on the relation between HRV and surgical procedure. For 112 children with Fontan circulation, HRV was analyzed using power spectral analysis. Spectral power was determined in three regions: very-low-frequency (VLF), low-frequency (LF), and high-frequency (HF) regions. Patients were compared with 66 healthy controls subject. Patients with LT were compared with patients who had EC. The children with Fontan circulation showed a significantly reduced HRV including total power (P < 0.0001), VLF (P < 0.0001), LF (P < 0.0001), and HF (P = 0.001) compared with the control subjects. The LT and EC patients did not differ significantly. Reduced HRV was found in both the LT and EC patients. In terms of HRV reduction, EC was not superior to LT.

- ObjectiveFontan surgery is performed in children with univentricular heart defects. Previous data regarding permanent pacemaker implantation frequency and indications in Fontan patients are limited and conflicting. We examined the prevalence of and risk factors for pacemaker treatment in a consecutive national cohort of patients after Fontan surgery in Sweden. MethodsWe retrospectively reviewed all Swedish patients who underwent Fontan surgery from 1982 to 2017 (n=599). ResultsAfter a mean follow-up of 12.2years, 13% (78/599) of the patients with Fontan circulation had received pacemakers. Patients operated with the extracardiac conduit (EC) type of total cavopulmonary connection had a significantly lower prevalence of pacemaker implantation (6%) than patients with lateral tunnel (LT; 17%). Mortality did not differ between patients with (8%) and without pacemaker (5%). The most common pacemaker indication was sinus node dysfunction (SND) (64%). Pacemaker implantation due to SND was less common among patients with EC. Pacemaker implantation was significantly more common in patients with mitral atresia (MA; 44%), double outlet right ventricle (DORV; 24%) and double inlet left ventricle (DILV; 20%). In contrast, patients with pulmonary atresia with intact ventricular septum and hypoplastic left heart syndrome were significantly less likely to receive a pacemaker (3% and 6%, respectively). ConclusionsThirteen percent of Fontan patients received a permanent pacemaker, most frequently due to SND. EC was associated with a significantly lower prevalence of pacemaker than LT. Permanent pacemaker was more common in patients with MA, DORV, and DILV.

- Sinus node dysfunction (SND) causes significant morbidity in patients after Fontan surgery. Heart rate variability (HRV) reflects the autonomic regulation of the heart, and changes in HRV have been associated with SND in adults. We aimed to study whether changes in HRV could be detected in 24-h electrocardiographic (ECG) recordings in Fontan patients with SND. We compared HRV results from two patient groups; patients with Fontan circulation who later required a pacemaker due to severe SND (n = 12) and patients with Fontan circulation and SND, without indication for pacemaker treatment (n = 11), with two control groups; patients with Fontan circulation without SND (n = 90) and healthy controls (n = 66). The Poincare plot index SD2 (representing changes in heart rate over 24-h) and the very low-frequency (VLF) HRV component were significantly higher in both SND groups, both compared with healthy controls and patients with Fontan circulation without SND. In SND patients with pacemakers, SD2 and VLF were slightly reduced compared to SND patients without pacemaker (p = 0.06). In conclusion, in Fontan patients with SND the HRV is significantly higher compared to healthy controls and Fontan patients without SND. However, in patients with severe SND requiring pacemaker, SD2 and VLF tended to be lower than in patients with SND without pacemaker, which could indicate a reduced diurnal HRV in addition to the severe bradycardia. This is a small study, but our results indicate that HRV analysis might be a useful method in the follow-up of Fontan patients regarding development of SND.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Adolescents with congenital heart disease transition from childhood to adulthood and transfer from pediatric-oriented to adult-oriented care. High-level empirical evidence on the effectiveness of transitional care is scarce. This study investigated the empowering effect (primary outcome) of a structured person-centered transition program for adolescents with congenital heart disease and studied its effectiveness on transition readiness, patient-reported health, quality of life, health behaviors, disease-related knowledge, and parental outcomes e.g., parental uncertainty, readiness for transition as perceived by the parents (secondary outcomes). Methods: The STEPSTONES-trial comprised a hybrid experimental design whereby a randomized controlled trial was embedded in a longitudinal observational study. The trial was conducted in seven centers in Sweden. Two centers were allocated to the randomized controlled trial-arm, randomizing participants to intervention or control group. The other five centers were intervention-naïve centers and served as contamination check control group. Outcomes were measured at the age of 16 years (baseline), 17 years, and 18.5 years. Results: The change in empowerment from 16 years to 18.5 years differed significantly between the intervention group and control group (mean difference = 3.44; 95% confidence interval = 0.27–6.65; p = .036) in favor of intervention group. For the secondary outcomes, significant differences in change over time were found in parental involvement (p = .008), disease-related knowledge (p = .0002), and satisfaction with physical appearance (p = .039). No differences in primary or secondary outcomes were detected between the control group and contamination check control group, indicating that there was no contamination in the control group. Discussion: The STEPSTONES transition program was effective in increasing patient empowerment, reducing parental involvement, improving satisfaction with physical appearance, and increasing disease-related knowledge. © 2023 Society for Adolescent Health and Medicine

- Measurements of the Q-T interval are less reliable in children than in adults. Identification of superior diagnostic tools is warranted. This study aimed to investigate whether a vectorcardiogram (VCG) recorded from three orthogonal leads (X, Y, Z) according to Frank is superior to a 12-lead electrocardiogram (ECG) in providing a correct long Q-T syndrome (LQTS) diagnosis in children. This LQTS group consisted of 35 genetically confirmed carriers of mutations in the KCNQ1 (n = 29) and KCNH2 (n = 6) genes. The control group consisted of 35 age- and gender-matched healthy children. The mean age was 7 years in the LQTS group and 6.7 years in the control group (range, 0.5-16 years). The corrected Q-T interval (QT(c)) was measured manually (QT(man)) by one author (A.W.). The 12-lead ECG automatic measurements (QT(ECG)) and interpretation (QT(Interpret)) of QT(c) were performed with the Mac5000 (GE Medical System), and the VCG automatic measurements (QT(VCG)) were performed with the Mida1000, CoroNet (Ortivus AB, Sweden). By either method, a QT(c) longer than 440 ms was considered prolonged and indicative of LQTS. Of the 35 children with genetically confirmed LQTS, 30 (86 %) received a correct diagnosis using QT(VCG), 29 (82 %) using QT(man), 24 (69 %) using QT(ECG), and 17 (49 %) using QT(Interpret). Specificity was 0.80 for QT(VCG), 0.83 for QT(man), 0.77 for QT(ECG), and 0.83 for QT(Interpret). The VCG automatic measurement of QT(c) seems to be a better predictor of LQTS than automatic measurement and interpretation of 12-lead ECG.

- BACKGROUND: Infants with moderate to severe congenital heart disease (CHD) are at a higher risk for growth failure and malnutrition due to increased metabolic demands and inadequate energy intake. This state requires meals that are more frequent and a special enriched diet, which may have negative implications on oral health.AIM: To examine the oral colonisation of some bacteria associated with caries development during infancy; mutans streptococci (MS) and lactobacilli (LCB) in infants with CHD and whether their dietary intake had an impact on the bacterial levels.DESIGN: This was a prospective case-control study. 11 infants with CHD and 22 healthy, age-matched infants were enrolled. Saliva samples and food diaries were collected at 6, 9, and 12 months of age. The total viable counts of MS and LCB in saliva were determined, and energy intake, meal frequency, intake of proteins, fat, carbohydrates and sucrose were calculated.RESULTS: At 12 months of age, the MS count was higher in the CHD group than in the controls (p<0.01), and MS constituted a higher ratio of the total viable count of oral bacteria (p<0.01). Meal frequency was higher in the CHD group at 6 and 9 months of age than in the controls (p<0.05). The intake of sucrose did not differ between the groups, while the total carbohydrate intake was higher in the control group at 6 and 12 months of age (p<0.05). Compared with the control group, which had six courses of antibiotic administration, the CHD infants had 21 courses (p<0.05).CONCLUSIONS: Infants with severe CHD have higher levels of MS at 12 months of age than the healthy controls. A higher meal frequency and use of diuretic medication and antibiotics may have influenced MS colonisation.

Tidskriftsartikel (refereegranskat)abstract
- We report a case of recurrent syncope in association with moderate ventricular dysfunction and mild AV-valve regurgitation in an 18-year-old girl, 4 years after she underwent total cavopulmonary connection surgery. Cardiac catheterization revealed a transpulmonary gradient of 1-2 mmHg. During exercise, a dramatic fall in blood pressure and blood oxygenation was observed, paralleled by an increase in heart rate and central venous pressure. Although a slight increase in pulmonary vascular resistance could not be excluded, the reaction was interpreted in terms of an extremely low transpulmonary gradient in association with ventricular dysfunction. Five months after heart transplantation, the patient has been completely free from syncope. Fontan circulation usually involves a delicate haemodynamic situation which may necessitate haemodynamic re-evaluations, including dynamic measurements of the central venous pressure during exercise. Also a moderate ventricular dysfunction may result in compromised pulmonary circulation which in turn may lead to syncope during exercise as a result of insufficient systemic circulation.

- INTRODUCTION: Surgical repair of coarctation of the aorta (CoA) is a safe procedure in children, however the condition is known for its potential recurrence and other related complications. The available evidence shows abnormal intrinsic properties of the aorta in CoA, thus suggesting additional effect, even after CoA repair, on left ventricular (LV) function. Accordingly, we sought to obtain a better understanding of LV myocardial mechanics in very early-corrected CoA using two-dimensional STE.METHODS AND RESULTS: We retrospectively studied 21 patients with corrected CoA at a median age of 9 (2-53) days at three time points: 1) just before intervention, 2) at short-term follow-up and 3) at medium-term follow-up after intervention and compared them with normal values. Speckle tracking analysis was conducted via vendor independent software, Tomtec. After intervention, LV function significantly improved (from -12.8±3.9 to -16.7±1.7; p<0.001), however normal values were not reached even at medium term follow-up (-18.3±1.7 vs. -20±1.6; p=0.002). Medium term longitudinal strain correlated with pre intervention EF (r=0.58, p=0.006). Moreover, medium term subnormal values were more frequently associated with bicuspid aortic valve (33.3% vs. 66.6%; p<0.05).CONCLUSION: LV myocardial function in neonates with CoA can be feasibly evaluated and followed up by speckle tracking echocardiography. LV subendocardial dysfunction however, remains in early infancy coarctation long after repair. Long-term follow-up through adulthood using myocardial deformation measurements should shed light on the natural history and consequences of this anomaly.
