Intermediate-term outcomes of the arterial switch operation for transposition of great arteries in neonates: alive but well?
Transposition of great arteries, including complex types, can be corrected with low surgical risk and good intermediate survival; however, neurodevelopmental outcome is a concern. These data suggest that although anatomic complexity may not affect late outcome, there may be potentially modifiable preoperative factors that can be optimized to improve developmental outcomes.
The Colloss E device improved early osseointegration of implants grafted with beta-TCP granules and increased their mechanical implant fixation to the level of allografted implants. The experiment indicates that ceramic bone substitutes may be a viable alternative to allograft when combined with an osteogenic signal such as Colloss E.
