title: Left ventricular aneurysm using the Dor technique: mid-term results.
abstract: OBJECTIVE
  We have retrospectively analyzed the early and the mid-term results of the operations for modified endoventricular circular patch plasty for left ventricular aneurysm (LVA) repair in our clinic.
  
  
  METHODS
  Sixty-seven cases with anterior LVA were included in the study. Mean age of the patients were 64.8 +/- 8.9 (ranged from 51 to 74) years. Fifty-three patients were male and 14 female (M:F = 3.8). Preoperative left ventricular ejection fraction (LVEF) was 30.8% +/- 4.5%, LV end-diastolic diameter (LVEDD) 6.0 +/- 1.9 cm, and end-systolic diameter (LVESD) was 4.6 +/- 0.8 cm in average. Coronary revascularization was performed in 61 patients and mitral ring annuloplasty in five patients.
  
  
  RESULTS
  Thirty-day mortality was 5.9%. The surviving 63 patients were followed up for 4.3 +/- 2.3 years on average (ranged from 0.2 to 8.5 years), adding up to 267.8 patient/years. In the immediate postoperative and long-term follow-up, there was a significant improvement in LVEF, LVESD, LVEDD, and mitral valvular function. Four patients died in the follow-up with only a single patient due to cardiac causes. The five years survival was 87.7% +/- 4.1% and the freedom from cardiac death was 98.2% +/- 1.7%.
  
  
  CONCLUSIONS
  LVA repair with Dor procedure can be performed with low mortality. With appropriate repair of LVA and coronary revascularization, patients may have benefit both for survival and also for clinical status.
