Long-term quality of life in adults following truncus arteriosus repair

To date, few studies have assessed the quality of life following congenital cardiac surgery. In this study, we aimed at determining the quality of life after truncus arteriosus (TA) repair using the Short Form 36 questionnaire in adult survivors.

Seventy-three patients (age >18 years) who underwent TA repair at the Royal Children's Hospital, Australia were identified for the study. Of these, 42 patients (58%, 42/73) participated in the study and completed the Short Form 36 questionnaire. The results of the 8 domains and the derived health state summary score (Short Form Six Dimension, SF-6D) were compared with age-matched Australian population controls, and with patients who underwent the arterial switch operation (ASO).

Compared with the age-matched Australian population, 18- to 24-year-old TA patients (31%, 13/42) had lower scores in 6 of 8 domains; 25- to 34-year-old TA patients (36%, 15/42) scored lower in 5 of 8 domains; and 35- to 44-year-old TA patients (33%, 14/42) scored lower in 4 of 8 domains. SF-6D scores were not significantly different between TA patients and the age-matched Australian population. Compared with patients who underwent ASO, 18-to 24-year-old TA patients scored lower in 3 of 8 domains; and 25- to 34-year-old TA patients scored lower in 2 of 8 domains. There was no significant difference in SF-6D scores between TA and patients who underwent the ASO.

Adult survivors of TA have similar quality of life compared with age-matched Australian controls measured by SF-6D. Despite a higher reoperation rate in TA patients, they have similar quality of life compared with ASO patients.
