  "abstract": "Introduction: Chagas heart disease (ChHD) is a leading trigger of end-stage heart failure in Latin America, with heart transplantation as its final treatment. Large-scale individual patient data (IPD) evidence on transplant immunosuppression, parasite reactivation and long-term prognosis remains scarce.\n\nMethods: We conducted an IPD meta-analysis by retrieving eligible studies up to October 4, 2025, extracting individual clinical data and adopting one-stage IPD and Cox regression analyses.\n\nResults: Sixteen studies with 305 ChHD transplant recipients were enrolled. Male sex was associated with increased risks of complications, reactivation, and death in observational analyses. Similarly, AZA exposure was associated with a lower risk of reactivation, and MMF exposure was associated with a lower risk of death. Notably, exploratory historical comparison suggests relatively favourable long-term survival among selected ChHD transplant recipients relative to published cohorts of other cardiomyopathies, though this finding cannot be adequately adjusted for key patient-level confounders.\n\nDiscussion: These associations are subject to confounding by indication, transplantation era, monitoring strategies, and switching-time bias. They therefore cannot be interpreted as causal treatment effects, nor can they establish that any one regimen is superior. In selected patients with end-stage Chagas heart disease, heart transplantation is a feasible treatment option associated with acceptable long-term survival outcomes.\n\nSystematic Review Registration: PROSPERO [CRD420251163696].",
