Childhood cardiovascular morphology and function following abnormal fetal growth
Studies examining the link between abnormal fetal growth and cardiac changes in childhood have presented conflicting results. We studied the effect of abnormal fetal growth on cardiac morphology and function during childhood, while controlling for body size, composition and postnatal factors. We report on the follow-up of 90 children (median age 5.81 years, IQR 5.67; 5.95) born appropriate for gestational age (AGA, N = 48), small for gestational age (SGA, N = 23), or large for gestational age (LGA, N = 19); SGA and LGA defined as birth weight Z-score + 2, respectively. We examined the heart using echocardiography, including Doppler and strain imaging, in relation to anthropometrics, body composition, blood pressure, physical activity, and diet. Although groupwise differences in body size decreased during the first year after birth, LGA remained larger at follow-up, with higher lean body mass and BMI, while SGA were smaller. Slight changes in left ventricular diastolic function were present in SGA and LGA, with SGA showing increased mitral diastolic E- and A-wave peak flow velocities, and increased septal E/E ' ratio, and LGA showing larger left atrial volume adjusted for sex and lean body mass. In univariate analyses, lean body mass at follow-up was the strongest predictor of cardiac morphology. We found no groupwise differences at follow-up for ventricular sphericity, cardiac morphology adjusted for lean body mass and sex, or blood pressure, diet, or physical activity. Cardiac morphology is predicted by lean body mass during childhood, even in the setting of abnormal fetal growth. Our results are consistent with a limited effect of fetal programming on cardiac dimensions during childhood. Minor changes in diastolic function are present in both SGA and LGA children, however, the clinical significance of these changes at this stage is likely small.Peer reviewe

Maternal obesity and gestational diabetes : Impact on arterial wall layer thickness and stiffness in early childhood - RADIEL study six-year follow-up
Background and aims: Gestational diabetes (GDM) and maternal obesity are linked to weight gain in childhood and an increased risk of cardiovascular disease later in life. We assessed the effects of GDM and maternal obesity on arterial function and morphology in relation to body anthropometrics and composition in early childhood. Methods: We assessed body size and composition, blood pressure (BP), arterial morphology and stiffness in 201 pairs of obese mothers (pre-pregnancy BMI 30.7 +/- 5.6 kg/m(2), 96 with GDM) and their children at 6.1 years (SD 0.5). Results: Child BMI (z-score 0.45 +/- 0.92; p <0.001) and common carotid intima-media thickness (IMT, z-score 0.15 +/- 0.75, p=0.003) were increased compared with a healthy Finnish reference population. No associations with maternal GDM was found. Carotid IMT and pulse wave velocity were unrelated to child sex, anthropometrics, body composition, BP, as well as maternal anthropometrics and body composition. Carotid stiffness was independently predicted by second trimester fasting glucose. Child lean body mass was the strongest independent predictor for radial (RA), and brachial artery (BA) lumen diameter (LD) and BA IMT (LD: RA: r(2)=0.068, p <0.001; BA: r(2)=0.108, p <0.001; IMT: BA: r(2)=0.161, p <0.001) and carotid LD (r(2)=0.066, p <0.001). Conclusions: Children of obese mothers have increased BMI, blood pressure and carotid IMT suggesting a transgenerational effect of maternal obesity and clustering of cardiovascular risk factors in the population. Arterial dimensions were mainly predicted by child LBM, and not associated with maternal or child adiposity, or GDM. There was a weak association with maternal gestational fasting glucose and increased carotid artery stiffness.Peer reviewe
Ultra-high frequency ultrasound delineated changes in carotid and muscular artery intima-media and adventitia thickness in obese early middle-aged women
Obesity is linked to increased arterial size, carotid intima-media thickness and arterial stiffness. The effects of obesity and body composition on muscular artery intima-media and adventitia thickness has previously not been established. The aim of this study was to explore associations between carotid and muscular artery wall layer thickness with body composition and cardiovascular risk factors in early middle-aged women. This is a cross-sectional study including 199 women aged 40 +/- 4 years. Arterial lumen (LD), intima-media (IMT) and adventitia thickness (AT) were measured from carotid, brachial and radial arteries using ultra-high frequency ultrasound (22-71 MHz). Women with obesity had increased IMT in carotid (0.47 vs 0.45 mm), brachial (0.19 vs 0.17 mm) and radial arteries (0.16 vs 0.15 mm) and increased brachial AT (0.14 vs 0.13 mm). In multiple regression models all arterial LD (beta-range 0.02-0.03 mm/kg/m(2)), IMT (beta-range 0.91-3.37 mu m/kg/m(2)), AT (beta-range 0.73-1.38 mu m/kg/m(2)) were significantly associated with BMI. The IMT of all arteries were significantly associated with systolic blood pressure (beta-range 0.36-0.85 mu m/mmHg), attenuating the association between IMT and BMI (beta-range 0.18-2.24 mu m/kg/m(2)). Obese early middle-aged women have increased arterial intima media thickness and brachial artery adventitia thickness compared to non-obese counterparts. The association between BMI and intima-media thickness is partly mediated through blood pressure levels.Peer reviewe
No effect of gestational diabetes or pre-gestational obesity on 6-year offspring left ventricular function-RADIEL study follow-up
Aims We aimed to investigate associations between pre-pregnancy obesity, gestational diabetes (GDM), offspring body composition, and left ventricular diastolic and systolic function in early childhood. Methods This is an observational study, including 201 mother-child pairs originating from the Finnish Gestational Diabetes Prevention Study (RADIEL; 96 with GDM, 128 with pre-pregnancy obesity) with follow-up from gestation to 6-year postpartum. Follow-up included dyads anthropometrics, body composition, blood pressure, and child left ventricular function with comprehensive echocardiography (conventional and strain imaging). Results Offspring left ventricular diastolic and systolic function was not associated with gestational glucose concentrations, GDM, or pregravida obesity. Child body fat percentage correlated with maternal pre-pregnancy BMI in the setting of maternal obesity (r = 0.23,P = 0.009). After adjusting for child lean body mass, age, sex, systolic BP, resting HR, maternal lean body mass, pre-gestational BMI, and GDM status, child left atrial volume increased by 0.3 ml (95% CI 0.1, 0.5) for each 1% increase in child body fat percentage. Conclusions No evidence of foetal cardiac programming related to GDM or maternal pre-pregnancy obesity was observed in early childhood. Maternal pre-pregnancy obesity is associated with early weight gain. Child adiposity in early childhood is independently associated with increased left atrial volume, but its implications for long-term left ventricle diastolic function and cardiovascular health remain unknown.Peer reviewe
Transcatheter closure of atrial septal defects type 2 in children under three years of age
Background: Atrial septal defect (ASD) type 2, according to current standards, is closed percutaneously usually after the child has reached the age of four to five years. There are limited data regarding such treatment in younger infants.
Aim: We sought to evaluate the feasibility, safety, and efficacy of percutaneous ASD closure in children under three years of age.
Methods: The research group consisted of 157 children less than three years old with haemodynamically significant ASD, who underwent effective transcatheter ASD closure in a single tertiary centre between 1999 and 2014. The mean procedural age of the treated children was 2.2 years and mean weight was 12.5 kg. In all cases nitinol wire mesh devices were applied (mostly Amplatzer Septal Occluders). ASD was closed using standard technique (except a few cases wherein the left disc of the implant was inserted initially into the right pulmonary vein to prevent oblique position of the device). Procedure-related complications were divided into major and minor ones.
Results: Atrial septal defect was closed in 149 children: 97 with a single ASD and 52 with double/multiple ASD. The procedure was abandoned in eight patients (three with single and five with double/multiple ASD). No death or implant embolisation occurred during the procedure or follow-up, and there was one case of major postprocedural complications. Normalisation of the right ventricular diameter occurred in all patients during one-year follow-up. In the majority of children acceleration of physical development and resolution of accompanying morbidity were observed in follow-up.
Conclusions: Percutaneous ASD closure can be performed safely in children under three years of age with low risk of peri- or postprocedural complications

Application of new balloon catheters in the treatment of congenital heart defects
Introduction : Balloon angioplasty (BAP) and aortic or pulmonary balloon valvuloplasty (BAV, BPV) are well-established treatment options in congenital heart defects. Recently, significant technological progress has been made and new catheters have been implemented in clinical practice.
Aim: To analyze the results of BAP, BAV and BPV with the new balloon catheter Valver and its second generation Valver II, which the company Balton (Poland) launched and developed. These catheters have not been clinically evaluated yet.
Material and methods: We performed 64 interventions with Valver I and Valver II. With Valver I the following procedures were performed: 17 BPV (including 9 in tetralogy of Fallot – TOF), 10 BAV and 27 BAP in coarctations of the aorta (CoA) – including 9 native and 18 after surgery. With Valver II ten interventions were done – 3 BPV, 2 pulmonary supravalvular BAP (after switch operations), 2 BAP of recoarctations and 3 other BAP. Age of the patients ranged from a few days to 40 years.
Results: All procedures were completed successfully, without rupture of any balloon catheters. The pressure gradient drop was statistically significant in all groups: BPV in isolated pulmonary valvular stenosis 28.1 mm Hg (mean), BPV in TOF 18.7 mm Hg, BAV 32.8 mm Hg, BAP in native CoA 15.4 mm Hg and in recoarctations 18.6 mm Hg. In 3 cases during rapid deflation of Valver I, wrinkles of the balloons made it impossible to insert the whole balloon into the vascular sheath (all were removed surgically from the groin). No such complication occured with Valver II.
Conclusions : Valver balloon catheters are an effective treatment modality in different valvular and vascular stenoses
Ideal Cardiovascular Health and Vascular Phenotype Associations in Mothers with Obesity and Their Six-Year-Old Children
Background: Heredity and family-shared lifestyle contribute to cardiovascular risk, but the magnitude of their influence on arterial structure and function in early childhood is unknown. We aimed to assess associations between child and maternal ideal cardiovascular health, maternal subclinical atherosclerosis, and child arterial phenotype. Methods: Cross-sectional analysis of 201 mother-child pairs originating from the Finnish Gestational Diabetes Prevention Study (RADIEL) longitudinal cohort was done at child age 6.1 +/- 0.5 years with assessments of ideal cardiovascular health (BMI, blood pressure, fasting glucose, total cholesterol, diet quality, physical activity, smoking), body composition, very-high frequency ultrasound of carotid arteries (25 and 35 MHz), and pulse wave velocity. Results: We found no association between child and maternal ideal cardiovascular health but report evidence of particular metrics correlations: total cholesterol (r=0.24, P=0.003), BMI (r=0.17, P=0.02), diastolic blood pressure (r=0.15, P=0.03), and diet quality (r=0.22, P=0.002). Child arterial phenotype was not associated with child or maternal ideal cardiovascular health. In the multivariable regression explanatory model adjusted for child sex, age, systolic blood pressure, lean body mass, and body fat percentage, child carotid intima-media thickness was independently associated only with maternal carotid intima-media thickness (0.1 mm increase [95% CI 0.05, 0.21, P=0.001] for each 1 mm increase in maternal carotid intima-media thickness). Children of mothers with subclinical atherosclerosis had decreased carotid artery distensibility (1.1 +/- 0.2 vs 1.2 +/- 0.2%/10 mmHg, P=0.01) and trend toward increased carotid intima-media thickness (0.37 +/- 0.04 vs 0.35 +/- 0.04 mm, P=0.06). Conclusion: Ideal Cardiovascular Health metrics are heterogeneously associated in mother-child pairs in early childhood. We found no evidence of child or maternal Ideal Cardiovascular Health effect on child arterial phenotype. Maternal carotid intima-media thickness predicts child carotid intima-media thickness, but the underlying mechanisms remain unclear. Maternal subclinical atherosclerosis is associated with local carotid arterial stiffness in early childhood.Peer reviewe
