title: [Surgical repair of left ventricular aneurysm; long-term results].
abstract: OBJECTIVE
  The aim of this study was to evaluate the late results of left ventricular (LV) aneurysm repair.
  
  
  METHODS
  From July 1968 to 1999, 86 consecutive patients (74 male, 12 female, mean age 56.0 +/- 9.3) underwent LV aneurysm repair at our institute. The surgical methods were as follows; linear repair in 71 patients, endoaneurysmorrhaphy in 5, endoventricular circular plasty in 4, Jatene method in 1 and plication of aneurysm in 5. Thirty-nine patients underwent concomitant myocardial revascularization. Major arrhythmias occurred in 38 patients. The results were retrospectively reviewed and follow-up was achieved in 95.3%.
  
  
  RESULTS
  There were 6 operative deaths and 4 hospital deaths. Actuarial survival rate including the 10 deaths was 72.7% at 5 years and 46.3% at 10 years. In patients with coronary artery bypass grafting (CABG), survival rate was 82.2% at 5 years and 56.3% at 10 years, and was significantly higher than that in those without revascularization (p = 0.01). In patients without arrhythmias, survival rate was 79.2% at 5 years and 55.0% at 10 years, and was significantly higher than that in patients with arrhythmias.
  
  
  CONCLUSIONS
  The patients were not homologous and the techniques were not the same; however, in spite of these study limitations, patients who underwent revascularization, and were without major arrhythmias preoperatively, had better long-term survival.
