Background: Quality of life (QOL) in adolescents and adults who have undergone the Fontan procedure and are living with only 1 ventricle is presumed to be diminished. Objectives: This study aimed to compare QOL, health status, and prevalence of depression in adolescents/adults after the Fontan procedure with healthy counterparts and to identify predictors of QOL in the Fontan group. Methods: Using a comparative, cross-sectional design, 54 adolescents and adults with single ventricle congenital heart disease who have undergone the Fontan procedure were compared with 66 age-matched healthy counterparts. Quality of life, health status, depression, and social support were measured using the Satisfaction With Life Scale, Short Form Survey Version 2, Patient Health Questionnaire Depression Module, and Multidimensional Scale of Perceived Social Support. Clinical variables were abstracted from medical records. Predictors of QOL were determined using multiple linear regression. Results: Adolescents and adults in the Fontan group reported lower physical health status (mean [SD] = 46.5 [9.3] vs mean [SD] = 55.9 [5.1], P < .001) and were more depressed (mean [SD] = 7.3 [5.9] vs mean [SD] = 4.5 [4.3], P < .004) than their healthy counterparts. There were no differences in QOL, mental health status, or social support between the 2 groups. Functional status (New York Heart Association class), depression, and social support accounted for 55% of the variance in QOL in the Fontan group. Conclusions: Despite lower levels of physical health, the QOL of Fontan patients was comparable with that of their healthy counterparts; this finding contradicts previous proxy reports, self-reports, and assumptions that QOL is lower in patients with complex single ventricle congenital heart disease. However, because Fontan patients were more depressed than their healthy counterparts, the need for early screening and detection is warranted.

Background Cognitive deficits are common, long-term sequelae in children and adolescents with congenital heart disease (CHD) who have undergone surgical palliation. However, there is a lack of a validated brief cognitive screening tool appropriate for the outpatient setting for adolescents with CHD. One candidate instrument is the Montreal Cognitive Assessment (MoCA) questionnaire. Objective The purpose of the research was to validate scores from the MoCA against the General Memory Index (GMI) of the Wide Range Assessment of Memory and Learning, 2nd Edition (WRAML2), a widely accepted measure of cognition/memory, in adolescents and young adults with CHD. Methods We administered the MoCA and the WRAML2 to 156 adolescents and young adults ages 14–21 (80 youth with CHD and 76 healthy controls who were gender and age matched). Spearman’s rank order correlations were used to assess concurrent validity. To assess construct validity, the Mann–Whitney U test was used to compare differences in scores in youth with CHD and the healthy control group. Receiver operating characteristic curves were created and area under the curve, sensitivity, specificity, positive predictive value, and negative predictive value were also calculated. Results The MoCA median scores in the CHD versus healthy controls were (23, range 15–29 vs. 28, range 22–30; p < .001), respectively. With the screening cutoff scores at <26 points for the MoCA and 85 for GMI (<1 SD, M = 100, SD = 15), the CHD versus healthy control groups showed sensitivity of .96 and specificity of .67 versus sensitivity of .75 and specificity of .90, respectively, in the detection of cognitive deficits. A cutoff score of 26 on the MoCA was optimal in the CHD group; a cutoff of 25 had similar properties except for a lower negative predictive value. The area under the receiver operating characteristic curve (95% CI) for the MoCA was 0.84 (95% CI [0.75, 0.93], p < .001) and 0.84 (95% CI [0.62, 1.00], p = .02) for the CHD and controls, respectively. Discussion Scores on the MoCA were valid for screening to detect cognitive deficits in adolescents and young adults aged 14–21 with CHD when a cutoff score of 26 is used to differentiate youth with and without significant cognitive impairment. Future studies are needed in other adolescent disease groups with known cognitive deficits and healthy populations to explore the generalizability of validity of MoCA scores in adolescents and young adults.

Objectives. The study aims to describe the clinical profile of the adult Fontan survivor and identify the worries, symptoms, and the impact of cardiac surveillance most commonly experienced. Design. A descriptive, cross‐sectional design was used. Setting. The study was performed in outpatient adult and pediatric cardiology clinics in university‐affiliated and private practice offices. Patients. Fifty‐four adolescent and adult patients with single ventricle congenital heart disease who have undergone the Fontan procedure participated in the study. The mean age was 26 ± 9 years with 52% female and 63% Caucasian. Outcome Measures. Demographic and clinical data were obtained by a standard intake form and retrospective chart reviews. The Congenital Heart Disease TNO/AZL Adult Quality Of Life questionnaire was completed to assess worries, symptoms, and the impact of cardiac surveillance. Results. The majority were single (73%), employed or full‐time students (93%), with health insurance (94%), had a single left ventricle (78%), the diagnosis of tricuspid atresia or double inlet left ventricle (59%), lateral tunnel Fontan type (44%), history of arrhythmias (76%), left ventricle ejection fraction percentage >50 (66%), oxygen saturations >90% (70%), frequent headaches (50%), scoliosis (22%), varicose veins, ascites, and liver cirrhosis (46%), normal body mass index (59%), and New York Heart Association class I (48%) and II–III (52%). Primary worries related to current health (83%), job/employment (69%), ability to work, (61%) and living independently (54%). The most bothersome symptoms were shortness of breath with ambulation (69%), dizziness (61%), and palpitations (61%). Conclusions. Fontan survivors experience residua and sequelae from multiple surgical procedures and the natural disease course. Our results support the need for ongoing assessment of both physical symptoms and psychosocial concerns, and suggest the need for multiple risk factor intervention strategies that improve physical and emotional health in Fontan survivors

Introduction: Adolescents and young adults with congenital heart disease [CHD] show a range of memory deficits, which can dramatically impact their clinical outcomes and quality of life. However, few studies have identified predictors of these memory changes. The purpose of this investigation was to identify predictors of memory deficits in adolescents and young adults with CHD after surgical palliation compared to healthy controls. Method: 156 adolescents and young adults [80 CHD and 76 controls; age 14-21 years] were recruited and administered an instrument to assess memory [Wide Range Assessment of Memory and Learning 2nd Edition – general memory index (GMI) score] and completed questionnaires that measure anxiety, depression, sleepiness, health status, and self-efficacy. Descriptive and non-parametric statistics were used to assess group differences, and logistic regression to identify predictors of memory deficits. Results: CHD subjects consisted of 58% males, median age 17 years, 41% Hispanic, and medians of 2 previous heart surgeries and 14 years since last surgery. Memory deficits [GMI < 85] were identified in 50% CHD compared to 4% healthy controls [median GMI 85 vs. 108, p <0.001]. Of GMI subscale medians, CHD subjects had significantly worse memory performance vs. healthy controls [verbal 88 vs. 105, p <0.001; attention 88 vs. 109, p<0.001; working memory 86 vs. 108, p <0.001]. No significant differences appeared between groups for visual memory. Multiple clinical and psychosocial factors were identified which were statistically different on bivariate analyses between the subjects with and without memory deficits. By multivariate analysis, male gender, number of surgeries, anxiety, and self-efficacy emerged as independent predictors of memory deficits. Conclusion: Adolescents and young adults with CHD, more than a decade since their last surgery, show significant verbal, attention and working memory deficits over controls. To enhance patient self-care, clinicians should explore ways to reduce anxiety, improve self-efficacy, and increase use of visual patient education material, especially in CHD males.
