The authors apologize for an error in the above stated paper. In the body of the paper, it is stated that “ECMO was used 44 times (20 (27%) in those with 22q11 deletion, 24 (22%) in those without) (p=0.45)”. This is also indicated in Table 2. This data is incorrect and was due to a database error. After extensive chart review, there were only 12 instances of ECMO use identified over the eight-year time period of the study. Seven (6.5%) of these occurred in patients with normal genotype and five (6.8%) in patients with 22q11 deletion. There was no significant difference between the two groups. The use of postoperative ECMO was much lower than reported in the manuscript.
