Insights
Infants undergoing aortic coarctation (CoA) repair have good outcomes, but reintervention is sometimes needed. Early repair (under 15 days) and prostaglandin E1 (PGE1) use increase reintervention risk.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Aortic coarctation (CoA) repair in infants presents challenges in achieving durable results without complications.
- Predicting the need for reintervention is crucial for improving long-term outcomes in pediatric patients.
Purpose of the Study:
- To identify predictors of aortic arch reintervention following surgical repair of aortic coarctation in infants.
- To analyze factors influencing the need for repeat aortic arch procedures in this population.
Main Methods:
- Retrospective analysis of 530 infants with isolated CoA or CoA with ventricular septal defect (VSD) undergoing aortic arch repair before 3 months of age.
- Data collected between January 2000 and March 2014, with a median follow-up of 7.57 years.
- Statistical analysis to determine risk factors for aortic arch reintervention.
Main Results:
- 11.5% of patients required aortic arch reintervention, with freedom from reintervention at 5 years being 88.5%.
- Risk factors for reintervention included repair at age <15 days and the intraoperative use of prostaglandin E1 (PGE1).
- End-to-end repair in patients receiving PGE1 showed a higher risk of recoarctation compared to extended end-to-side repair.
Conclusions:
- Aortic coarctation repair in young infants generally yields good outcomes.
- The use of PGE1 may alter aortic arch anatomy, potentially complicating surgical resection and increasing reintervention risk.
- Further research is needed to optimize preoperative management, particularly concerning PGE1 use.
Objectives:
The main challenge of aortic coarctation (CoA) repair in infants is to obtain durable results without morbidity. We aimed to describe predictors of aortic arch reintervention after aortic CoA repair.
Methods:
Between January 2000 and March 2014, we retrospectively included consecutive infants with isolated CoA or CoA with ventricular septal defect (CoA + VSD) who had surgical repair of the aortic arch before 3 months of age.
Results:
Five hundred and thirty patients were included: 308 (58%) patients had isolated CoA and 222 (42%) patients had CoA + VSD. Three hundred and eighty-five patients (72.6%) had CoA repair, 51 patients (9.6%) had CoA repair with closure of VSD and 94 patients (17.8%) had CoA repair with pulmonary artery banding. Mean age at operation was 13 ± 1.6 days, with 294 patients (55.5%) operated on before 2 weeks. Median follow-up was 7.57 years. Sixty-one patients (11.5%) needed reintervention on the aortic arch. Freedom from aortic arch reintervention was 90% at 1 year and 88.5% at 5 years. Proportions of aortic arch reintervention were similar in the different surgical strategy groups (P = 0.80). However, in patients receiving prostaglandin E1 (PGE1), the end-to-end repair was at higher risk of recoarctation compared to the extended end-to-side repair (P = 0.033). The risk factors of aortic arch reintervention were age at repair <15 days (P = 0.034) and the need for PGE1 infusion at surgery (P = 0.0043).
Conclusions:
CoA repair in young infants has an overall good outcome. The use of PGE1 may modify the aortic arch anatomy and mask the boundaries of the resection to be performed. PGE1 treatment should be studied more specifically in another study to improve preoperative management.
