title: Epilepsy After Heart Transplant: A Single Center Experience.
abstract: OBJECTIVE
  Cardiac transplant is the best treatment for patients with end-stage heart failure. Neurologic complications occur at a rate of 30% to 80% in patients undergoing cardiac transplant. Seizures occur at a rate of 2% to 20%. The main causative factors include immunosuppressant drug toxicity, infections, brain lesions, and metabolic disorders. Here, our aim was to determine seizure types and associated conditions in patients undergoing cardiac transplant and to report our treatment experience at our institution.
  
  
  METHODS
  We retrospectively evaluated the medical records of 109 patients who underwent cardiac transplant between 2004 and 2016. We recorded demographic data, immunosuppressive treatment, seizure type, cause, recurrence rate, and treatment.
  
  
  RESULTS
  Of 109 patients, 13 had seizures after cardiac transplant. Our study involved 69 adult and 40 pediatric patients. The pediatric patients had an age range of 1 to 17 years, with a mean age of 9.6 years (22 female and 18 male patients). Five pediatric patients had seizures (4 female and 1 male patient). The seizure causes included 2 postarrest hypoxic encephalopathies and 3 posterior reversible encephalopathies. Adult patients ranged from 18 to 63 years old, with a mean age of 42.3 years (54 male and 15 female patients). Eight patients in the adult patient group had seizures (5 female and 3 male patients). Seizure causes were ischemic cerebrovascular events in 2 patients, metabolic disorders in 2, posterior reversible encephalopathies in 3, and postarrest hypoxic brain in 1.
  
  
  CONCLUSIONS
  Seizure is an important complication after cardiac transplant. At our institution, the most common cause of seizure was posterior reversible encephalopathy, with immunosuppressant drugs being responsible.
