title: Surgery for endomyocardial fibrosis revisited.
abstract: OBJECTIVE
  To identify life expectancy after surgery for endomyocardial fibrosis (EMF) and the events that influence it.
  
  
  METHODS
  Eighty-three patients with EMF underwent endocardial decortication and atrioventricular valve replacement or repair, between December 1977 and December 1997. There were 66 (79.6%) female and 17 (20.4%) male patients, ranging in age from 4 to 59 years (mean, 31). Thirty-seven (44.5%) had biventricular disease, 34 (41.0%) had disease of the right ventricle alone and 12 (14.5%) had EMF confined to the left ventricle. All were in functional class III or IV (New York Heart Association classification).
  
  
  RESULTS
  Sixty-eight (81.9%) patients survived the operation and were followed up for periods ranging from 2 months to 17 years. The total follow-up time was 6290 patient/months (mean, 92 months). There were 15 late deaths, but in six, the cause was not related to the underlying disease. Four (5.8%) patients presented recurrence of the fibrosis and were reoperated on and in six (8.8%), EMF appeared in the other ventricle. Five (7.3%) patients were reoperated on to replace either a valve prosthesis or a native valve which had been preserved during the first procedure. Only 24 (45%) of the 53 surviving patients are in functional class I or II. The actuarial probability of survival at 17 years, including operative mortality, was 55%.
  
  
  CONCLUSIONS
  Surgical treatment of EMF should be considered a palliative procedure because surgery does not alter the progressive nature of the disease. However, surgical therapy is recommended for patients with EMF and heart failure as it is their only hope of survival.
