title: Dynamic cardiomyoplasty: long-term clinical results in patients with dilated cardiomyopathy.
abstract: BACKGROUND
  Dynamic cardiomyoplasty has been considered to be an effective method of surgical treatment of patients with end-stage heart failure, and is an alternative to heart transplantation.
  
  
  METHODS
  We critically evaluated the long-term course of 52 patients with dilated cardiomyopathy who underwent dynamic cardiomyoplasty and were followed-up for up to 110 months.
  
  
  RESULTS
  Dilated cardiomyopathy was due to undetermined cause in 42 patients (80.8%), Chagas disease in 8 (15.4%), viral infection in 1 (1.9%), and peripartum cardiomyopathy in 1 (1.9%). In the nonchagasic group the survival rates were 79.5% +/- 6.1%, 67.8% +/- 7.1%, 53.7% +/- 8.3%, 49.9% +/- 8.3%, 14.9% +/- 12.2%, and 14.9% +/- 12.2%, respectively, at 12, 24, 48, 60, 80 and 110 months of follow-up. In the chagasic patients the survival rates were 37.5% +/- 17.1%, 12.5% +/- 11.7%, 12.5% +/- 11.7% and 0%, respectively, at 12, 24, 48, and 60 months of follow-up, making chagasic cardiomyopathy a possible contraindication for dynamic cardiomyoplasty.
  
  
  CONCLUSIONS
  There was no correlation between the clinical improvement and hemodynamic data. Ventricular fibrillation was a frequent cause of immediate and late death, suggesting the need for prophylactic use of antiarrhythmic drugs or implantable cardioverter/ defibrillators.
