Abstract

Abstract: Background: We aimed to describe the incidence, risk factors, and clinical outcomes of pericardial effusions within 6 months after pediatric heart transplantation (HT). Methods: A single‐center retrospective cohort study was performed on all pediatric HT recipients from 2004 to 2018. Logistic regression was used to identify factors associated with pericardial effusions post‐HT, and survival was compared using log‐rank test. Results: During the study period, 97 HTs were performed in 93 patients. Fifty patients (52%) had a ≥small pericardial effusion within 6 months, 16 of which were, or became, ≥moderate in size. Pericardial drain was placed in 8 patients. In univariate analysis, larger recipient body surface area ( p = .01) and non‐congenital heart disease ( p = .002) were associated with pericardial effusion development. Donor/recipient size ratios, post‐HT hemodynamics, and rejection did not correlate with pericardial effusion development. In multivariable analysis, non‐congenital heart disease (adjusted odds ratio 3.3, p = .01) remained independently associated with development of pericardial effusion. There were no significant differences in post‐HT survival between patients with and without ≥small ( p = .68) or ≥moderate pericardial effusions ( p = .40). Conclusions: Pericardial effusions are common after pediatric HT. Patients with cardiomyopathy, or non‐congenital heart disease, were at higher risk for post‐HT pericardial effusions. Pericardial effusions increased morbidity but had no effect on mortality in our cohort. The risk factors identified may be used for anticipatory guidance in pediatric HT.
