“…In our large multicenter cohort study, the mortality was low (6%) (Figure 2), comparable to that of the most recent series, but still double that of the STS Congenital Database (2.8%) 18 and the United Kingdom database (2.5%) 19,20 . Although there were no significant differences in the patient population, surgical variables, or the rates of the percentage of ECMO, the discrepancy we encountered could be related to the higher mortality found in neonates (25% in our series vs. 5.3% of Straka et al) 18 . As shown by other authors, in our study neonates ( p = .01), lower body weight ( p = .003), lower BSA ( p = .01), and the need for postoperative MCS ( p < .001) were all associated with higher in‐hospital mortality 1,18 .…”
