Objectives: Heart transplantation (HT) in children with heterotaxy may be affected by anomalous cardiac position, venous return, and splenic function. Outcomes are not well described. We compared post-HT outcomes, including survival and resource utilization, among recipients with congenital heart disease (CHD) in the presence and absence of heterotaxy. Methods: Using linked Pediatric Health Information System and Scientific Registry of Transplant Recipients data (2001-2016), we identified 177 HT recipients with heterotaxy. We compared post-HT outcomes to 1,202 non-heterotaxy recipients with CHD in multivariable regression models. Length of stay (LOS) and cost from HT to discharge were also compared. Results: Heterotaxy HT recipients were older (median age 5.1 vs. 1.6 years, p<0.001) and more often Black, Asian, Hispanic, or "other" non-Caucasian (54 vs. 32%, p<0.001). Heterotaxy was independently associated with increased mortality (HR 1.61, [95% CI 1.20-2.15], p=0.001), even among 6-month survivors (HR 2.00 [1.17-3.43], p=0.012). Heterotaxy recipients more commonly required dialysis (OR 2.64 [1.52-4.56], p=0.001) and cardiac reoperation (OR 2.36 [1.29-3.41], p=0.003) prior to discharge. They had longer ischemic times (19 additional minutes [10.4-27.6], p<0.001, adjusted for organ procurement distance), ICU LOS (16 vs. 13 days, p=0.012), and hospital LOS (median 26 vs. 23 days, p=0.005). Post-HT hospitalization costs were also greater
