Why the study?
Does surgery in a more recent era (1995-1999) compared to an earlier era (1990-1994) improve early mortality and long-term survival in patients with congenital heart defects?
Does surgery in a more recent era (1995-1999) compared to an earlier era (1990-1994) improve early mortality and long-term survival in patients with congenital heart defects?
Early mortality after surgery for congenital heart defects has substantially decreased over time, which translates into significantly improved long-term survival.

Associated with lower early mortality and better survival in severe congenital heart defects; leaves open contributions of surgical versus other era-specific factors.
Eskedal et al. (2005) studied this question.
