Predictive factors of surgical repair technique in infants with coarctation of the aorta
Authors' conclusion
The aortic arch diameter is the most discriminating parameter for the type of surgical repair technique in infant CoA. An aortic arch threshold value of 3.6 mm in infant population is predictive of aortic arch repair and should be considered a practical indicator of the hypoplastic nature of the aortic arch.
Study context
- Population
- Infants aged <1 year who underwent coarctation of the aorta (CoA) surgical repairinfants (68% males)
- Participants
- 680 infants
- Exposure
- Pre-natal and post-natal factors associated with the type of surgical technique repair in infant CoA
- Outcome
- Surgical repair technique (simple end-to-end repair, extended end-to-end repair, or aortic arch repair)
Methodological details4 congenital heart disease (CHD) surgical centres in France, over 11 years
