Abstract:  We sought to outline trends in anthropometric growth before and after cardiac transplantation and to document our experience with the use of EFS in this population. A total of 130 patients (59% male) were enrolled and followed for a median of 4.4 yr after transplantation. Negative changes over time in weight z-score (EST: −0.256 [0.160] z/yr, p = 0.01), height z-score (EST: −0.214 [0.096] z/yr, p = 0.03), and BMI z-score (EST: −0.287 [0.161] z/yr, p = 0.07) were observed prior to transplantation. Significant increases in weight z-score (EST: +0.342 [0.143] z/yr, p < 0.001) and BMI z-score (EST: +0.396 [0.140] z/yr, p = 0.005) were seen in the first 18 months following transplantation. No further increases in height, weight, or BMI z-score were seen beyond this. Forty-two (32%) patients received EFS. Prior to transplantation, it was not found to be associated with change in anthropomorphic growth. Post-transplantation exposure to EFS was associated with a faster increase in weight z-score (EST: +0.480 [0.231] z/yr, p = 0.04) and height z-score over time (EST: +0.366 [0.141] z/yr, p = 0.01). Normalization of weight and height z-scores was not achieved during the study follow-up period. This study suggests that further investigation into the role of EFS is warranted to identify strategies to improve growth in pediatric heart transplant recipients.
