We present 2 patients who underwent orthotopic heart transplantation f
or end-stage Chagas' cardiomyopathy. Despite immunosuppressive therapy
, postoperative prophylaxis with nifurtimox appeared to prevent Trypan
osoma cruzi reactivation. Neither patient has shown signs of Chagas' m
yocarditis, and both are clinically well 12 and 72 months after transp
lantation. The successful outcome of our patients suggests that heart
transplantation is a reasonable therapeutic option in patients with en
dstage Chagas' cardiomyopathy.
