Regular physical activity prevents chronic disease and moderate to vigorous participation provides additional health benefits. Therefore, adolescents with congenital heart disease risk developing latent diseases due to real or perceived physical activity restrictions. Habitual physical activity levels, psychological determinants and advice received were examined by postal survey of 434 West Australian adolescents aged 12-18 years with congenital heart disease. Survey results (n = 153) were compared with published normative adolescent data. Total activity was classified as vigorous, adequate or inadequate according to metabolic equivalents, reported frequency and duration. Comparable numbers of respondents and healthy peers were active (winter 62% vs 74%; and summer 73% vs 82% respectively, p = 0.27). However, significantly fewer male respondents were classified as vigorously active compared with healthy peers, in both winter (48% vs 67%, p < 0.02), and summer (48% vs 69%, p = 0.04). Similar, but non-significant, trends were found when comparing female respondents with healthy peers and for mild versus severe disease groups. Self-efficacy ratings did not explain differences in physical activity intensity. Congenital heart disease may impact on the intensity of physical activity undertaken by affected adolescents thus denying additional health benefits. Physiotherapists could facilitate these adolescents to achieve more moderate to vigorous physical activity, to offset adult sedentary behaviour.

Improvements in the diagnosis and surgical treatment of congenital heart disease during infancy and childhood have resulted in an outstanding increase in the prevalence of these entities during adulthood. Congenital heart disease in the adult represents a new diagnostic challenge to the consultant cardiologist, unfamiliar with the anatomical and functional complexities of cardiac malformations. Assessment of adult congenital heart disease with imaging techniques can be as accurate as in children. However, these techniques cannot substitute for a detailed clinical assessment. Physical examination, electrocardiography and chest x-rays remain the three main pillars of bedside diagnosis. Transthoracic echocardiography is undoubtedly the imaging technique which provides most information, and in many situations no additional studies are needed. Nevertheless, ultrasound imaging properties in adults are not as favorable as in children, and prior surgical procedures further impair image quality. Despite recent advances in ultrasound technologies such as harmonic or contrast imaging, other diagnostic procedures are sometimes required. Fortunately, transesophageal echocardiography and magnetic resonance imaging are easily performed in the adult, and do not require anaesthetic support, in contrast to pediatric patients. These techniques, together with nuclear cardiology and cardiac catheterization, complete the second tier of diagnostic techniques for congenital heart disease. To avoid unnecessary repetition of diagnostic procedures, the attending cardiologist should choose the sequence of diagnostic techniques carefully; although the information this yields is often redundant, it is also frequently complementary. This article aims to compare the diagnostic utility of different imaging techniques in adult patients with congenital heart disease, both with and without prior surgical repair.

In a 4-year period, 83 fetuses have been noted to have an abnormal fetal heart position within the thorax on fetal echocardiography. In 55 cases where the heart lay in the right chest, this was due to the presence of a left-sided diaphragmatic hernia; in one case, the heart was abnormally far into the left chest because of a left-sided diaphragmatic hernia. Of the remaining 27 cases, the heart lay in the right chest in 16 cases. In seven of those 16, there was a congenital heart malformation; in six, there were lung anomalies; a hiatus hernia was present in one; both congenital heart disease and lung abnormality were present in one and one fetus had isolated dextrocardia. In nine cases, the heart lay in the center of the chest and in three, the heart lay further to the left than normal. Congenital heart disease was found in nine of these 12. Chromosomal anomalies were found in four of the 27 cases with an abnormal heart position but an intact diaphragm. In summary, it is important to be familiar with the normal cardiac orientation within the thorax and to investigate abnormalities of position. A diaphragmatic hernia will be the most common underlying cause but, where the diaphragm is intact, other explanations must be sought in order to counsel correctly or plan appropriate perinatal management. Lung disorders, congenital heart disease and chromosomal anomalies will be the principal differential diagnoses.

Chronic heart failure is a state of immune activation, and endotoxin is a potential trigger for cytokine production. Our aim was to study whether immune activation and endotoxemia occur in adults with congenital heart disease. We prospectively measured tumor necrosis factor (TNF)-alpha, soluble TNF receptors (sTNFR-1, sTNFR-2), interleukin-6, interleukin-10, endotoxin, and soluble CD14 levels in 52 consecutive adults with congenital heart disease (age 34 +/- 2 years [mean +/- SEM]) and 18 healthy controls (age 31 +/- 1 years). A variety of congenital heart lesions were studied: single ventricle physiology (n = 15), systemic right ventricle (n = 7), tetralogy of Fallot (n = 20), and "other" congenital heart disease (n = 10). Patients were subgrouped into asymptomatic (New York Heart Association [NYHA] class I, n = 11), mild (NYHA class II, n = 30), and moderate/severe (NYHA class III/IV, n = 11) categories. Patients had elevated TNF and interleukin-6 levels compared with controls (TNF 2.8 vs 2.1 pg/ml, p <0.05; interleukin-6 8.5 vs 5.7 pg/ml, p <0.001). TNF levels were higher in patients with moderate/severe symptoms compared with patients who were asymptomatic or had mild symptoms (p <0.05). Soluble TNFR-1 levels related directly to the degree of systemic ventricular impairment (p <0.05). There were no significant differences in sTNFR-1, sTNFR-2, interleukin-10, or sCD14 levels between patients and controls. Endotoxin levels were greater in patients with congenital heart disease versus controls (0.40 vs 0.26 endotoxin units/ml, p <0.0001). Thus, adults with congenital heart disease have elevated levels of inflammatory cytokines and bacterial endotoxin, which relate to functional status. Congenital heart disease in adults may be amenable to novel anti-inflammatory therapies in selected patients.

Aiming to document the incidence and type of associated congenital heart disease, 20 children affected with the congenital rubella syndrome have been evaluated during a 5 year period, starting 1988. Congenital heart disease was detected in 45% of the cases. Persistent ductus arteriosus was the most frequent finding, followed by ventricular and atrial septal defects. Hearing disturbances occurred in 83% of the 12 cases studied. Ophthalmic lesions appeared in 69% of the 13 cases analysed, congenital cataracts being the most frequent one. An association of 66% was found between ophthalmic and heart lesions. Regarding the nutritional index, 70% of the cases were situated between the 25th and 50th percentile. The relevant incidence of congenital defects and the documentation of an important number of cases in a short period of time point out to a significant prevalence of the syndrome with imperative need improve the vaccination programs.

Congenital heart disease has the characteristics of a disease that is suited to screening, and the four-chamber view is an effective screening tool with a sensitivity of 40% to 50%. The use of multiple cardiac views can increase the pre-natal detection to 60% to 80%. Given that most infants with congenital heart disease are born to low-risk women, routine screening is warranted. Early pre-natal diagnosis provides an opportunity to exclude associated extracardiac and chromosomal abnormalities, discuss pregnancy options, adjust obstetric management, prepare parents for delivery of an affected baby, and plan delivery in a tertiary care center. Despite the widespread use of ultrasonography, only 15% to 30% of infants with congenital heart disease are identified prenatally. There is a need to do better.

This study represents the development and validation of a cardiac-specific module of the generic health-related quality of life (HRQoL) instrument, the TAAQOL (TNO/AZL Adult Quality Of Life), for young adults with congenital heart disease (CHD). Items were selected based on literature, an explorative previous study in CHD patients, interviews with patients, and the advice of experts. The newly developed Congenital Heart Disease-TNO/AZL Adult Quality of Life (CHD-TAAQOL) was tested in 156 patients with mild or complex CHD and consisted of three hypothesised subject scales: 'Symptoms' (9 items), 'Impact Cardiac Surveillance' (7 items), and 'Worries' (10 items). Cronbach's alpha for the three scales were 0.77, 0.78, and 0.82, respectively. Scale structure was confirmed by Principal Component Analysis, corrected item-scale and interscale correlations. Overall, 55% of reported health status problems were associated with negative emotions, which is an argument for assessing HRQoL as a concept distinct from health status. Convergent validity with validated generic instruments (TAAQOL and Short Form-36, SF-36) showed satisfactory coefficients. Discriminant validity was proven by significantly higher scores for mild CHD patients compared with those with complex CHD. In conclusion, the CHD-TAAQOL module together with the generic TAAQOL can be used to assess group differences for cardiac-specific HRQoL in young adults with CHD. Testing psychometric properties of the CHD-TAAQOL shows satisfactory results. However, to detect changes in HRQoL over time, further research is needed.

The objective of this study was to investigate the outcomes of children with heart failure of various etiologies requiring temporary use of currently available technology in the U.S.A. after extracorporeal life support (ECLS) [left ventricular assist device (LVAD) or extracorporeal membrane oxygenation (ECMO)] at Texas Children's Hospital. Between July of 1995 and October of 2002, 2847 patients underwent congenital heart surgical repairs with the aid of cardiopulmonary bypass at Texas Children's Hospital. During this period, 17 patients required chronic mechanical circulatory assistance with Biomedicus centrifugal pump (n=8) or Thoratec LVAD (n=4), and ECMO (n=5). Six out of 17 patients required ECLS for postcardiotomy heart failure. Seven of the 17 patients had congenital heart disease, six had cardiomyopathy, three had late acute rejection following heart transplantation, and one had myocardial infarction. Twelve patients survived and five patients expired. Six of 12 survivors recovered sufficient cardiac function to allow device removal; and the remaining six patients underwent heart transplantation. Three out of five deaths were ECMO patients. The need for ECLS following repair of congenital heart disease is extremely rare in our institution. The requirement for the use of ECMO confers a significantly higher mortality presumably because of associated combined cardiopulmonary failure. Congenital heart disease appears to be associated with significantly higher mortality.

Ebstein's anomaly (EA) is a rare but fascinating congenital heart disorder accounting for <1% of all congenital heart defects. Since its description in 1866, dramatic advances in diagnosis and therapy have been made. In this review, we describe current diagnostic criteria and classification, natural history, clinical features, and prognosis, typical echocardiographic features and pathologic findings, and the spectrum of associated cardiac malformations including left heart anomalies associated with EA. Differences between Ebstein-like changes associated with congenitally corrected transposition and EA are described. The spectrum of typical ECG and conduction system changes, arrhythmias including accessory pathways and ectopic atrial tachycardias related to EA are also reviewed. Differential diagnosis of EA is discussed including tricuspid valve dysplasia and prolapse as well as arrhythmogenic right ventricular cardiomyopathy. The review describes management options in EA including catheter interventions, indication for operation and surgical options including tricuspid valve repair and replacement. Overall, EA is a complex congenital anomaly with a broad pathologic-anatomical and clinical spectrum and no two patients are alike. Therefore, precise knowledge of the different anatomic and hemodynamic variables, associated malformations and management options are essential. Management of EA patients is complex. Thus it is important that these patients are regularly seen by a cardiologist with expertise in congenital heart disease.

Congenital heart disease is the most common form of structural heart disease affecting women of childbearing age in developed countries. Pregnancy in these patients is associated with an increased risk to both mother and fetus. Appropriate prepregnancy evaluation and counseling is recommended to assess the pregnancy-related maternal and fetal risk and to identify patients who should avoid pregnancy. Once pregnancy occurs, cardiovascular reevaluation is generally recommended; the frequency is individualized. Monitoring during delivery may be necessary and the postpartum period is a concern in select individuals. Data regarding the outcome of pregnancy in patients with operated congenital cardiac defects are available. Individualized care is mandatory.
