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.

The concept of sequential analysis of congenitally malformed hearts is now widely accepted, although some aspects remain controversial. In this review, we analyse the evolution of the scgmental approach, showing how our own concepts of analysis have chaanged little since our initial description, heart dicrates the presence of the atrial, ventriclar, and arterial segments, Analysis depends upon recognizing the morphologic differences of the components within each segment, and then how these parts are joined together across the atrioventicular and ventriculo-arterial Junctions. The distinction of chambers and arterial trunks follows the principle of the morphologic method, namely that scructures be identified on the basis of their own intrinsic morphology, and not according to other features which themselves might be variable. Differentiation of junctional arrangements as opposed to segmental stucture resolves ongoing controversics such as the nature of “univentricular hearts”.Analysis in the fashion proposed shows that there is nothing intrinsically complicated with malformed hearts.

Aims: We investigated the incidence and outcome of cardiac malformations in 53 patients with Williams syndrome. Methods and results:The mean age, and period of follow-up, were 3.6 and 5.3 years, with standard deviations of 4.0 and 5.6 years, respectively. Of the patients, 45 (85%) had cardiovascular anomalies, often combined. Males presented earlier than females, at the ages of 2.1 years, with standard deviation of 2.8 years, as opposed to 4.5 years, with standard deviation of 4.2 years (p < 0.01). Supravalvar aortic stenosis occurred in 32 patients (71%), pulmonary arterial stenosis in 17 (38%), and mitral valvar prolapse in 12 (27%), 9 of these having regurgitant valves. Pulmonary valvar stenosis, ventricular septal defect, coarctation of the aorta, persistent patency of the arterial duct, hypertrophic cardiomyopathy, and subaortic stenosis all occurred less frequently. In 21 patients (47%), 24 surgical or catheter interventions had been made, most often for repair of supravalvar aortic stenosis, undertaken on 16 occasions with just one recurrence, and in 4 along with surgery to the mitral valve. Other lesions requiring intervention were pulmonary valvar stenosis, pulmonary arterial stenosis, coarctation of the aorta, and subaortic stenosis. We lost 3 patients (7%), with severe supravalvar aortic stenosis and moderate or severe mitral regurgitation, 2 early and one late after surgery. Conclusion: The most frequent cardiovascular anomalies in Williams syndrome were supravalvar aortic stenosis, pulmonary arterial stenosis, and mitral valvar prolapse, which occurred more frequently in our patients than previously observed. Patients with left ventricular pressure and volume overload were at greater risk.

Perhaps because it guards the inlet to the lesser circulation, the morphologically tricuspid valve has received less attention in terms of its anatomy than the well-explored mitral valve, which will receive attention in a subsequent review in this supplement.1 As we will show in our initial review, nonetheless, the approach to morphological analysis is the same for both valves, irrespective of whether the specific morphology is displayed in the autopsy room or the echocardiographic laboratory. It is essential that the valve be analysed so as to reveal the precise structure of each if its components – the so-called valvar complex.2 Equally important, in the current era, with the burgeoning use of three-dimensional displays that place the heart firmly within the context of the body, it is essential that the components of the valve be described as seen relative to the bodily axis,3 rather than following the present custom of describing the heart as though it is removed from the body and positioned on its own apex.

Right ventricular function is a crucial determinant of long-term outcomes of children with heart disease. Quantification of right ventricular systolic and diastolic performance by echocardiography is of paramount importance, given the prevalence of children with heart disease, particularly those with involvement of the right heart, such as single or systemic right ventricles, tetralogy of Fallot, and pulmonary arterial hypertension. Identification of poor right ventricular performance can provide an opportunity to intervene. In this review, we will go through the different systolic and diastolic indices, as well as their application in practice. Quantification of right ventricular function is possible and should be routinely performed using a combination of different measures, taking into account each disease state. Quantification is extremely useful for individual patient follow-up. Laboratories should continue to strive to optimise reproducibility through quality improvement and quality assurance efforts in addition to investing in technology and training for new, promising techniques, such as three-dimensional echocardiography.

In this review, we describe the experience from 13 European centres using the CardioSEAL and Starflex double umbrella devices to close interatrial communications within the oval fossa (so-called ‘stcundum’ defects). Between October 1996 and April 1999, the procedure was attempted in 334 patients with a mean age of 12 years and a mean weight of 44kg. The mean measured stretched diameter of the defect was 15 mm. In the overall group, the defect was solitary in 245 patients (73%), multiple in 21 (6%), associated with an aneurysm of the flap valve in 15 (5%), was represented by patency of the oval foramen in 44 (13%), and was a fenestration in a Fontan repair in 9 (3%). In all patients, the devices were inserted under general anesthesia, using fluoroscopic and transesophageal echocardiographic control. Implantation was achieved in 325 (97,3%). The device embolized within either a few minutes or a few hours in 13 patients (4%). Of these, uncomplicated surgical repair was undertaken in 10, while the device was retrieved in 3 using catheters and a second device was successfully implanted. Residual shunting was detected immediately after the procedure in 41% of the patients, with the incidence decreasing to 31% at discharge, 24% at 1 month, 21% at 6 months, and 20.5% at one year. During the period of follow-up, elective surgical repair became necessary in two patients, due to malposition of the device in one, and late embolization in the other. Fractures of arms were seen in 6.1%, most commonly with the largest devices. All those with fractured arms of the device were asymptomatic, and no clinical complications related to the fractures were observed. There were no arrythmias, endocarditis, valvar distortion, thromboembolic events, or other complications. After one year of follow-up, clinical success, defined as complete closure of the defect or presence of only a trivial leak, had been obtained in 92.5% of the patients. We conclude, therefore, that these devices produce excellent results when used to close defects of small to moderate size. Results are less than optimal, or else complications ensure, when attempts are made to close very large defects.

In 2012, the American Heart Association and the American Academy of Paediatrics released a scientific statement with guidelines for the evaluation and management of the neurodevelopmental needs of children with CHD. Decades of outcome research now highlight a range of cognitive, learning, motor, and psychosocial vulnerabilities affecting individuals with CHD across the lifespan. The number of institutions with Cardiac Neurodevelopmental Follow-Up Programmes and services for CHD is growing worldwide. This manuscript provides an expanded set of neurodevelopmental evaluation strategies and considerations for professionals working with school-age children with CHD. Recommendations begin with the referral process and access to the evaluation, the importance of considering medical risk factors (e.g., genetic disorders, neuroimaging), and the initial clinical interview with the family. The neurodevelopmental evaluation should take into account both family and patient factors, including the child/family’s primary language, country of origin, and other cultural factors, as well as critical stages in development that place the child at higher risk. Domains of assessment are reviewed with emphasis on target areas in need of evaluation based on current outcome research with CHD. Finally, current recommendations are made for assessment batteries using a brief core battery and an extended comprehensive clinical battery. Consistent use of a recommended assessment battery will increase opportunities for research collaborations, and ultimately help improve the quality of care for families and children with CHD.

Background: Hypertrophic cardiomyopathy is a common cause of sudden death in children. In this study, we aimed to identify clinical measures for stratification of this risk in childhood. Patients and methods: By means of a retrospective cohort study from six regional centres of paediatric cardiology, we identified 128 patients with hypertrophic cardiomyopathy presenting below 19 years of age, with a mean follow-up of 10.8 years. Of the patients, 31 had died, 16 suddenly, with a median age at sudden death of 13.3 years. Results: Cox regression shows that electrocardiographic voltages, analysed as the sum of the R and S waves in all six limb leads (p equal to 0.001), and septal thickness expressed as proportion of the 95th centile for age (p equal to 0.036), were independent predictors of sudden death. When the sum of the R and S waves is over 10 millivolts, the odds ratio for sudden death was 8.4, with 95% confidence intervals from 2.2 to 33.7 (p equal to 0.0012), and finding a septal thickness over 190% of 95th centile for age gives an odds ratio of 6.2, with confidence intervals from 1.5 to 25.1 (p equal to 0.011). Noonan's syndrome, with a p value equal to 0.043, and the ratio of the left ventricular wall to its cavity in diastole, with a p value equal to 0.005, were independent predictors of death in cardiac failure, with a ratio of the mural thickness to the dimension of the cavity over 0.30 giving an odds ratio of 36.0, with confidence limits from 4.2 to 311, and a p value equal to 0.00009. At follow-up, patients deemed to be at a high risk of dying suddenly were identified by the combination of the sum of the R and S waves greater than 10 millivolts and septal thickness over 190%, with a sensitivity of 91%, specificity of 78%, positive predictive value of 50%, and a negative predictive value of 97%. Conclusions: Children at high risk of dying suddenly with hypertrophic cardiomyopathy, with a subsequent annual mortality of 6.6%, can be distinguished at the time of diagnosis from those patients having a low risk of sudden death, the latter with an annual mortality of 0.27%.

The anomalous aortic origin of a coronary artery from the wrong sinus of Valsalva with interarterial, intramural, and/or intraconal course is a rare congenital anomaly that is associated with a high risk of sudden death in children. The Congenital Heart Surgeons’ Society established the Registry of Anomalous Aortic Origin of the Coronary Artery to help determine the outcome of children and young adults managed with surgical intervention versus observation and to test the hypothesis that subsets of patients with anomalous aortic origin of a coronary artery can be identified in whom the risk of intervention is less than the risk of observation. All institutional members of the Congenital Heart Surgeons’ Society were recruited for participation. The registry consists of a retrospective cohort of patients diagnosed between 1 January, 1998 and 20 January, 2009 and a prospective, population-based cohort of patients newly diagnosed from 21 January, 2009 onwards. Baseline demographics, diagnoses, and results of tests will be obtained through a review of the medical records. Annual follow-up data will be collected. Data will be analysed for different factors of risk at diagnosis, different strategies of treatment, and the impact of both on the outcomes of the patients. As of June 2010, 28 institutions had applied for approval from their institutional review board and 16 institutions had received approval from their institutional review board. Seventy-four patients have enrolled to date. We hope to use the established Pediatric Cardiomyopathy Registry as a guide to successful implementation, with a cooperative effort between institutions. The overall purpose of the Registry of Anomalous Aortic Origin of the Coronary Artery is to determine the outcome of surgical intervention versus observation in children and young adults with anomalous aortic origin of a coronary artery, and to describe the natural and “unnatural” history of these patients over the course of their lifetime. In this report, we describe the creation and design of the Registry of Anomalous Aortic Origin of the Coronary Artery. Data from the registry will be published at a later date.

Interventional cardiology for paediatric and congenital cardiac disease is a relatively young and rapidly evolving field. As the profession begins to establish multi-institutional databases, a universal system of nomenclature is necessary for the field of interventional cardiology for paediatric and congenital cardiac disease. The purpose of this paper is to present the results of the efforts of The International Society for Nomenclature of Paediatric and Congenital Heart Disease to establish a system of nomenclature for cardiovascular catheterisation for congenital and paediatric cardiac disease, focusing both on procedural nomenclature and the nomenclature of complications associated with interventional cardiology. This system of nomenclature for cardiovascular catheterisation for congenital and paediatric cardiac disease is a component of The International Paediatric and Congenital Cardiac Code. This manuscript is the second part of the two-part series. Part 1 covered the procedural nomenclature associated with interventional cardiology as treatment for paediatric and congenital cardiac disease. Part 2 will cover the nomenclature of complications associated with interventional cardiology as treatment for paediatric and congenital cardiac disease.

Hearts which, at first sight, seem to have a solitary chamber within their ventricular mass have long been the subject of controversy. As difficult as it is to manage these cardiac malformations medically and surgically, it has been at least as challenging, to date, merely to describe and classify them. Even the most commonly used terms, “single ventricle” and “univentricular heart”, spark heated debate. In distant times, when congenitally malformed hearts were pathological curiosities, these entities were described as “cor triloculare biatriale”. Therein lies the beginning of the problem, since when hearts of this type were examined by more enlightened pathologists, such as the great Maude Abbott,1 it became plain that the apparently solitary ventricular mass in reality possessed a second, albeit much smaller, chamber. Abbott described this second structure as the “outlet chamber”. This convention of describing a “single ventricle”, albeit with a co-existing “outlet chamber”, that presumably lacked ventricular status, continued throughout the first half of the twentieth century, although it had been recognised by then that hearts could rarely be found with truly solitary ventricles, and these were typically deemed to be common structures. Van Praagh et al.2 neatly summarised the problem with this approach when they pointed out that the so-called “single ventricle” possessed two ventricular chambers, whilst the “common ventricle” described the truly solitary arrangement. In their seminal investigation of 1964, Van Praagh et al.2 analysed only those hearts unified because of double inlet atrioventricular connection, or alignment. They excluded arbitrarily from their investigation all hearts with atrioventricular valvar atresia, despite the similarity in morphology between many of these latter lesions and the hearts with double inlet.3
