IntroductionParents of children with congenital cardiac disease suffer from psychological stress and financial burdens. These costs have not yet been quantified.Materials and methodsIn cooperation with paediatricians, social workers, and parents, a questionnaire was devised to calculate direct non-medical and indirect costs. Direct non-medical costs include all costs not directly related to medical services such as transportation. Indirect costs include lost productivity measured in lost income from wages. Parents were retrospectively queried on costs and refunds incurred during the child’s first and sixth year of life. The questionnaire was sent out to 198 families with children born between 1980 and 2000. Costs were adjusted for inflation to the year 2006. Children were stratified into five groups according to the severity of their current health status.ResultsFifty-four families responded and could be included into the analysis (27.7%). Depending on severity, total direct non-medical and indirect costs in the first year of life ranged between an average of €1654 in children with no or mild (remaining) cardiac defects and an average €2881 in children with clinically significant (residual/remaining) findings. Mean expenses in the sixth year of life were as low as €562 (no or mild (remaining) cardiac defects) and as high as €5213 (potentially life-threatening findings). At both points in time, the highest costs were lost income and transportation; and day care/ babysitting for siblings was third.DiscussionFamilies of children with congenital cardiac disease and major sequelae face direct non-medical and indirect costs adding up to €3000 per year on average. We should consider compensating families from low socioeconomic backgrounds to minimise under-use of non-medical services of assistance for their children.

IntroductionStenoses in the pulmonary arterial system can have a significant negative impact on the early postoperative course in infants. Early recognition and aggressive management are mandatory.Patients and methodsWe describe our experience with 8 infants, with ages ranging from 3 to 9 months, weighing from 4.5 to 7.7 kilograms, who presented in the up to 18 days following construction of a shunt from the superior caval vein to the pulmonary arteries with clinical symptoms of obstructed pulmonary flow. We include also 2 infants in whom pulmonary arterial stents were implanted in the operating room. Cardiac catheterization showed significant stenoses or occlusion of the left pulmonary arteries in 9 infants, the right pulmonary arteries in 2, or the superior caval vein in 1, the investigation being prompted by the findings of supraphysiological superior caval venous pressures and systemic hypoxaemia. We implanted a variety of stents mounted on balloons ranging in diameter from 6 to 13 millimetres, with 7 placed across a newly created surgical anastomotic site.ResultsAll stenoses were crossed successfully, and stents implanted satisfactorily in all patients, albeit that 1 infant suffered an acute tear of the left pulmonary artery, requiring immediate reoperation. This patient died 72 hours later due to a diffuse coagulopathy. All other patients demonstrated sustained clinical improvement following the procedure. At follow-up, 7 of the 9 survivors have progressed to completion of the Fontan circulation. Redilation of the stents was required in the interim, prior to completion of the Fontan circulation, in 4 of them. In 2 patients, the previously implanted stents were incised during the Fontan completion, permitting placement of the extracardiac Goretex conduit from the inferior caval vein to the pulmonary arteries.ConclusionsStents can successfully be implanted perioperatively in the pulmonary arterial system during infancy, and redilated, with improvement in clinical outcome in the majority of those with clinically relevant obstruction.

Aims: StEP TWO is a school- and family-based intervention consisting of extra lessons, healthy nutrition and physical education for overweight and obese children in primary schools, aimed at reducing body mass index by maintenance or reduction of weight, and improving motor abilities. We analysed differences in changes in anthropometric, cardiovascular and obesity parameters between children who underwent intervention, non-participants in intervention, and controls.Methods: Anthropometric data and waist circumference were recorded for 1678 children; body mass index and body mass index–standard deviation score were calculated. Blood pressure was measured after 5 minutes at rest. 121 overweight and obese children enrolled at 3 schools involved in programmes of intervention were invited to take part; 40 of them completed the programme from November 2003 to July 2004. Of these overweight children, 74 were invited, but did not take part. As controls, we enrolled 155 overweight and obese children from 4 other schools.Results: After the programme, the children involved in intervention showed a lower increase in the body mass index (0.3 plus or minus 1.3 versus 0.7 plus or minus 1.2 kilograms per metre squared) and an approximately three times higher diminution of the body mass index–standard deviation score in comparison with their controls (−0.15 plus or minus 0.26 versus 0.05 plus or minus 0.27). Systolic blood pressure was significantly lowered by 9.5 plus or minus 19.6 millimetres of mercury in those involved in intervention, but increased in the control group by 0.5 plus or minus 16.5 millimetres of mercury. Among those invited but not participating, the increase of the body mass index (0.5 plus or minus 1.3 kilograms per metre squared) was less, and the reduction of the body mass index-standard deviation score (−0.09 plus or minus 0.31) and systolic blood pressure (−5.3 plus or minus 15.6 millimetres of mercury) was higher than in the control group. Overweight but not obese children seem to benefit from a screening examination alone.Conclusions: Early preventive measures in schools are necessary and effective for overweight and obese primary school children. The screening itself seems also to have a minor positive effect, especially for overweight children. Sustainability of the observed improvements over a longer period remains to be confirmed.

Basic scientists, as well as cardiologists, are caught by the idea of curing ischaemic heart disease with cardiac progenitor or stem cells. This short review provides an overview of our current knowledge on the potential use of stem cells for cardiac disease. Since, in infants and children, aetiologies and pathomechanisms of critical cardiac disease are fundamentally different from those in adults, we will also address the question as to whether such young patients could be a therapeutic target at all, and in which respect it may be necessary to view treatment with stem cells from a different stance in the developing organism.

Obesity in childhood, which is associated with cardiovascular risk factors such as hypertension, is on the increase. Countermeasures are necessary. In this paper, we present the baseline and final data from the StEP TWO programme, a prospective study to prevent overweight and obesity in primary schools. Methods: We recorded and calculated, from 1689 children, anthropometric data, including analyses of bioelectric impedance, waist and hip circumferences, body mass index and its standard deviation, and the ratio of waist to hip. Blood pressure was measured after 5 minutes at rest. From the three schools involved in a programme of intervention, 121 children were invited to take part, and 40 (33.1 per cent) completed the programme. The effect was compared with 155 overweight and obese children identified at the 4 control schools. Results: 830 (49.5 per cent) boys and 848 girls (50.5 per cent) took part. Their mean age was 8.2 plus or minus 1.3 years, their height was 1.31 plus or minus 0.09 metres, they weighed 30.0 plus or minus 8.2 kilograms, and their mean index of body mass was 17.1 plus or minus 2.9 kilograms per metre squared. Of the children, 7.3 per cent were obese, 10.4 per cent were overweight, 75.7 per cent had normal weights, and 6.6 per cent were underweight. Resting hypertension was observed in 2.3 per cent of the children. Increased blood pressure was associated with a higher body weight, body mass index, standard deviation score for body mass index, and waist and hip circumferences (each p < 0.001), but not with the ratio of waist to hip. Hypertension at rest was also found in 11.0 per cent of obese children, 4.4 per cent of those who were overweight, 1.2 per cent of those with normal weight, and 1.0 per cent of underweight children (p < 0.001). After the intervention, the increase of the body mass index tended to be lower in those in whom we had intervened (p = 0.069), and in these the decrease of the standard deviation score for body mass index was significantly higher (p = 0.028). Systolic blood pressure was reduced by about 10 millimetres of mercury in those in whom we had intervened (p = 0.002), while there were no changes in the control group. Diastolic blood pressure was lowered by 3 millimetres of mercury, but this was not significant. Conclusion: Obese children had the highest values for systolic and diastolic blood pressure. Increased levels of blood pressure are associated with other parameters of obesity, such as the circumference of the waist and hip. Early preventive measurements in childhood are necessary, and appropriate intervention appears to be effective.

Their perceptual and motor experiences determine the physical and motor development of children, and impact also on their emotional, psychosocial, and cognitive development. Our aim, therefore, was to evaluate motor development in children with congenitally malformed hearts compared to their healthy peers.We compared 194 children, with a mean age of 10.0 years, and standard deviation of 2.7 years, representing the entire spectrum of congenital cardiac disease, to a control group of 455 healthy children, having a mean age 9.6 years, with standard deviation of 2.17 years. The bodily coordination test for children was used to examine motor development.Of the children with congenitally malformed hearts, 26.8% showed moderate, and 31.9% had severe disturbances of motor development, compared to 16.5% and 5.5% of the control group, the p-value for these differences being less than 0.001. The mean motor quotient adjusted for age and gender was lower in the children with congenitally malformed hearts than in their healthy peers, at 79.6, with standard deviation of 18.9 as opposed to 96.6, with standard deviation of 15, this difference having a p-value of less than 0.001. Depending on the presence, and/or the degree, of residual sequels, the children with congenitally malformed hearts were divided into two subgroups, with either no or mild residual sequels, or with significant sequels. The mean motor quotient was lower in those with significant residual sequels, at 75, with standard deviation of 19.3, as opposed to 83, with standard deviation of 17.9, the p-value for this difference being less than 0.01. In both subgroups, the mean motor quotient was lower, with a p-value of less than 0.01, than in the control group.Our findings show that children with congenitally malformed hearts have deficits in their motor development, these being found in the presence of no or mild sequels, as well as with significant residual sequels. Parental overprotection may contribute to these findings.

We occluded a large arterial duct in a patient with atrial fibrillation, using an Amplatzer duct occluder, with no residual shunt at the end of the procedure. Follow-up revealed recanalization, which was successfully treated with a 4 mm Amplatzer ASD occluder. It is speculated the reopening of the initially occluded duct was the consequence of anticoagulation needed because of the atrial fibrillation.
