Truncus arteriosus repair in neonates presents significant surgical challenges, but survival beyond the first year following repair is associated with excellent outcomes. Neonatal surgery and low operative weight are risk factors for early mortality, while a coronary artery anomaly is a risk factor for late mortality.
Objective: To examine the long-term surgical outcomes of patients who underwent truncus arteriosus (TA) repair. Methods: Between 1979 and 2018, a total of 255 patients underwent TA repair at 3 Australian hospitals. Data were obtained by review of medical records from initial admission until last cardiology follow-up. Results: At the time of TA repair, the median patient age was 44 days, and median weight was 3.5 kg. Early mortality was 13.3% (34 of 255), and overall survival was 76.8 +/- 2.9% at 20 years. Neonatal surgery and low operative weight were risk factors for early mortality. Most deaths (82.5%; 47 of 57) occurred within the first year following repair. A coronary artery anomaly and early reoperation were identified as risk factors for late mortality. A total of 175 patients required at least 1 reoperation, with overall freedom of reoperation of 2.9 +/- 1.5% at 20 years. Follow-up of survivors was 96% complete (191 of 198). The median duration of follow-up was 16.4 years. At the last follow-up, 190 patients were categorized as New York Heart Association class I/II, and 1 patient was class III. Conclusions: TA repair during the neonatal period presents significant surgical challenges. Neonates with signs of overcirculation should be operated on promptly. A coronary artery anomaly is a risk factor for late mortality. Survival beyond the first year following repair is associated with excellent outcomes.
