TI  - Evaluation of predictors of clinical outcome after partial left ventriculectomy.
PG  - 91-5
AB  - BACKGROUND: Outcome after partial left ventriculectomy (PLV) is difficult to 
      predict. Our goal was to determine if clinical measurements including exercise 
      testing could predict outcome after PLV. METHODS: Sixteen patients with dilated 
      cardiomyopathy had left ventricular ejection fraction, left ventricular 
      end-diastolic diameter, amount of mitral regurgitation (MR), New York Heart 
      Association (NYHA) functional class, and cardiopulmonary exercise testing 
      measurements measured before PLV and 3 months after PLV. Eleven patients who 
      remained stable after PLV (group 1) were compared with 5 patients who 
      deteriorated after PLV (group 2). RESULTS: Similar significant improvements were 
      seen in both groups 3 months post-PLV with respect to left ventricular ejection 
      fraction (group 1: 0.136+/-0.037 to 0.212+/-0.046; group 2: 0.139+/-0.042 to 
      0.179+/-0.073) and left ventricular end-diastolic diameter (group 1: 8.5+/-0.7 to 
      7.0+/-0.6 cm; group 2: 7.6+/-0.6 to 6.5+/-0.6 cm). The MR grade (1.0+/-0.6 versus 
      2.5+/-0.6), NYHA functional class (1.5+/-0.31 versus 2.5+/-0.6), and peak oxygen 
      consumption (17.8+/-1.1 versus 12.2+/-2.0) were significantly different in the 
      two groups 3 months after PLV (p < 0.05, analysis of variance). CONCLUSIONS: 
      Patients that do not show significant improvement in peak oxygen consumption, 
      NYHA class and significant decrease in the amount of MR 3 months after PLV, 
      compared with pre-PLV, are at increased risk of clinically deteriorating.
