ABSTRACT
BACKGROUND: There is variability in the impact of adult congenital heart disease (ACHD) on health-related quality of life (HRQoL). A greater insight into the impact of ACHD may be gained from investigating HRQoL in various diagnostic groups and considering the importance of psychosocial risk factors for poor HRQoL. OBJECTIVE: We compared the HRQoL of people with ACHD with normative data from the general population and among 4 diagnostic groups and identified risk factors for poor HRQoL in ACHD from a comprehensive set of sociodemographic, clinical, and psychosocial factors. METHODS: We conducted a cross-sectional study with 303 participants from 4 diagnostic groups Simple, Tetralogy of Fallot, Transposition of the Great Arteries, Single Ventricle who completed measures of illness perceptions, coping, social support, mood, and generic and disease-specific HRQoL. Data were analyzed using 1-sample t tests, analysis of variance, and hierarchical multiple regressions. RESULTS: There was diminished psychosocial HRQoL in the Simple group compared with the general population. Consistently significant risk factors for poor HRQoL included younger age, a perception of more severe symptoms due to ACHD, depression, and anxiety. Clinical factors were poor predictors of HRQoL. CONCLUSIONS: The findings highlight the need to develop intervention studies aiming to improve HRQoL in people with ACHD and the routine assessment of illness perceptions and mood problems during key periods in people's lives. This will help address patient misconceptions that could be tackled by clinicians or specialist nurses during routine outpatient appointments and identify people in need of psychological support.

OBJECTIVE: We carried out a cross-sectional study to assess cognitive function in a sample of adult CHD patients, within the Functioning in Adult Congenital Heart Disease study London. The association between cognitive functioning and disease complexity was examined. METHODS: A total of 310 patients participated in this study. Patients were classified into four structural complexity groups - tetralogy of Fallot, transposition of the great arteries, single ventricle, and simple conditions. Each patient underwent neuropsychological assessment to evaluate cognitive function, including memory and executive function, and completed questionnaires to assess depression and anxiety. RESULTS: Among all, 41% of the sample showed impaired performance (>1.5 SD below the normative mean) on at least three tests of cognitive function compared with established normative data. This was higher than the 8% that was expected in a normal population. The sample exhibited significant deficits in divided attention, motor function, and executive functioning. There was a significant group difference in divided attention (F=5.01, p=0.002) and the mean total composite score (F=5.19, p=0.002) between different structural complexity groups, with the simple group displaying better cognitive function. CONCLUSION: The results indicate that many adult CHD patients display impaired cognitive function relative to a healthy population, which differs in relation to disease complexity. These findings may have implications for clinical decision making in this group of patients during childhood. Possible mechanisms underlying these deficits and how they may be reduced or prevented are discussed; however, further work is needed to draw conclusive judgements.

With the advent of improved medical and surgical care in congenital heart disease, there has been an increase in the number of patients who survive into adulthood, giving rise to a new patient population 'Adults with congenital heart disease'. In the past, morbidity and mortality were the primary concerns for this group. However, with improvements in outcome attention has shifted to other factors such as psychosocial and cognitive functioning. This paper reviews the literature on the cognitive functioning in adult congenital heart disease patients. A total of five relevant articles were retrieved via electronic searches of six databases, including MEDLINE, EMBASE, CINAHL, AMED, PsychINFO, and PubMed. The results displayed a consensus on the presence of some cognitive difficulties in adult congenital heart disease patients. The aetiology of cognitive dysfunctions appears to be multifactorial. The literature is limited by the very small number of studies looking at adults with congenital heart disease, with the majority focusing on cognitive functioning among children with congenital heart disease. However, the presence of cognitive dysfunctions and the resulting impact on the patient's day to day lives warrant for a more detailed and prospective research to enhance the understanding of its aetiology and impact.
