Patient Summary

A 58 year old woman with a history of non-ischemic cardiomyopathy s/p orthotopic heart transplantation in 2015 presented with worsening dyspnea upon exertion. Dyspnea in a post cardiac transplant brings forth a wide differential diagnosis spanning all the typical causes of dyspnea as well as causes more specific or common to the patient with a heart transplant. In this particular case, TTE showed newly reduced ejection fraction and valvular disease. Cell mediated rejection was considered highest on the differential and confirmed on endomyocardial biopsy. Given hemodynamic compromise with multiple foci of myocyte damage on biopsy, she was started on high dose steroids and anti-thymocyte globulin for treatment of rejection.  Early identification and management of cell mediated rejection is crucial to the survival of patients like ours. Final diagnosis: orthotopic heart transplantation rejection.
