title: Left ventricular aneurysm repair: early survival.
abstract: BACKGROUND
  The aim of this study was to evaluate the early survival in patients submitted to left ventricular (LV) repair and concomitant myocardial revascularization.
  
  
  METHODS
  We retrospectively reviewed the records of 51 patients who were submitted to LV repair and concomitant myocardial revascularization between January 1998 and June 2003. Of 51 patients (44 males with a mean age of 60+/-9.2 years, and 7 females with a mean age of 61+/-6.5 years), 29 (56.9 %) were submitted to the McCarthy technique, 16 (31.3 %) to the technique that was described by Jatene and modified by Dor, and 6 (11.8%) to the Cooley technique (linear repair). The mean preoperative LV ejection fraction was 36.5+/-7.7 %, the mean preoperative LV end-diastolic diameter was 61.8+/-3.9 mm, the mean preoperative LV end-systolic diameter was 49.9+/-5.1 mm, the mean preoperative interventricular septal thickness was 9.7+/-1.7 mm, and finally, the mean posterior wall thickness was 8.9+/-1 mm. The mean follow-up was 30.7+/-23.4 months (range 11-82 months).
  
  
  RESULTS
  One patient died during surgery (1.9%) and one early postoperatively (1.9%). The causes of death were respectively irreversible ventricular fibrillation and low cardiac output syndrome. The overall survival at follow-up was 98% (49 patients). One patient died during follow-up of myocardial infarction. At follow-up, all patients presented with improved clinical symptoms, and had a better mean NYHA functional class with respect to the preoperative value (3.3+/-0.3 vs 2.0+/-0.5, p < 0.05). Besides, the mean CCS angina class decreased in all patients (3.4+/-0.2 vs 1.9+/-0.3, p < 0.05). The average LV ejection fraction increased from 36.3+/-7.7 to 44.3+/-4.9% (p < 0.001), the average LV end-diastolic diameter decreased from 61.7+/-3.9 to 55.5+/-5.6 mm (p < 0.001), and the average LV end-systolic diameter decreased from 49.9+/-5.1 to 40.4+/-5.1 mm (p < 0.001). No statistically significant difference was found between the preoperative and postoperative data regarding the interventricular septal thickness (9.7+/-1.7 vs 10.3+/-1.6 mm, p = NS), and the posterior wall thickness (9.7+/-1 vs 8.8+/-1.3 mm, p = NS).
  
  
  CONCLUSIONS
  LV aneurysm repair and concomitant myocardial revascularization may be performed with an acceptable surgical risk and a good early survival.
