Since the 1980s treatment techniques for congenital heart disease (ConHD) have gradually evolved. Therefore, actual information on the outcomes, including quality of life is required. Health-related quality of life was assessed long-term in four diagnostic groups of children, who underwent invasive treatment for ConHD between 1990 and 1995. The scores on the TNO-AZL Child Quality of Life Questionnaire (TACQOL) of both children with ConHD and their parents were compared with those of a same-aged reference group. The total sample of ConHD children (n = 113, 8-15 years old) obtained significantly lower mean scores on motor functioning, cognitive functioning, and positive emotional functioning than reference peers, reflecting an experience of poorer functioning. ConHD children, aged 8-11 years, obtained lower mean scores on 5 of the 7 TACQOL scales than reference peers. They also had a lower score on positive emotional functioning than 12- to 15-year-old ConHD children. The total sample of ConHD children obtained lower outcomes compared to their parents on 4 of the 7 TACQOL scales. No significant differences were found in health-related quality of life between ConHD boys and girls, neither between different diagnostic groups. Overall, this sample of recently treated ConHD children showed a worse health-related quality of life compared to reference groups. These findings deserve further attention.

The purpose of this study was to investigate the cardiological health status and health-related quality of life after the arterial switch operation (ASO) for transposition of the great arteries (TGA) in comparison with a normative reference group. Chart review and cross-sectional systematic follow-up, including echocardiography, exercise testing, and electrocardiography, were performed on all survivors of ASO for TGA between 1990 and 1995. Health-related quality of life (HRQOL) was assessed using a standardized questionnaire. A normative reference group was included. Forty-nine survivors [median age at operation 13 days, mean age at follow-up 11 +/- 2 years (37/49 with intact ventricular septum] were identified. Thirty-three of 49 patients (67%) [22/33 TGA with intact ventricular septum (IVS)] participated in cross-sectional follow-up. Cumulative 10-year event-free survival was 88% and the re-intervention rate 6%. Aortic root dilatation occurred in 70% of patients; none had severe aortic regurgitation. Left ventricular function was normal. Exercise performance (85% of reference capacity, p = 0.02), maximal oxygen uptake (85%, p < 0.01) and peak heart rate (95%, p < 0.01) were decreased. Exercise electrocardiogram was normal as was rhythm status. Unfavourable outcomes on HRQOL were found for motor functioning and positive emotional functioning. Overall there were no significant differences between TGA/IVS and TGA/VSD. We conclude that at mid- to long-term follow-up after ASO, major events and re-interventions (6%) occur infrequently. Exercise capacity and maximal oxygen uptake are lower than those in a reference population, which could not be related to diminished ventricular function. Aortic root dilatation is frequent, irrespective of the anatomical subgroup. Severe aortic regurgitation or left ventricular dilatation was not found. The unfavourable health-related quality of life deserves further attention.

Longstanding mild PR in PS patients can lead to an enlarged RV, reduced RV function and reduced exercise capacity. Despite more PR and larger RV volumes in TOF patients, exercise capacity and biventricular function are similar in both patient groups.
