A case report: pause and consider the late complications of heart transplantation

Abstract

AbstractBackgroundA 75-year-old woman with a past medical history significant for non-ischaemic cardiomyopathy status post orthotopic heart transplant, type II diabetes mellitus, hypertension, chronic kidney disease stage III, chronic anaemia, and chronic diarrhoea presented with nausea, vomiting, and an unexplained fall 23 years after original transplantation.Case summaryDuring her hospital stay, she had multiple episodes of sinus arrest with syncope, preceded by seizure like activity. She was stabilized, and broad work up revealed an occult brain mass that was ultimately resected and consistent with post-transplant lymphoproliferative disease.DiscussionFeatures that make this case study unique include the late onset and location of the malignancy, the absence of Epstein–Barr virus involvement, and asystole that was potentially neurologically mediated and induced by a brain space occupying mass. This case offers insight into potential late parasympathetic reinnervation of transplanted hearts, adds to the growing literature regarding the connection between the brain and the heart, and reviews potential complications in patients with a remote history of heart transplantation.
