title: [Echocardiographic assessment of pathologic geometry in the left left ventricle with aneurysm before and after endoventricular plasty].
abstract: Large LV aneurysm (LVA) leads to progressive distortion of ventricular geometry. Endoventricular plasty (EVP) maintains LV original shape and size and may restrain this process.
  
  
  OBJECTIVE
  Echocardiographic estimation of LVA size. Assessment of the results of EVP regarding operative technique. Assessment if the initial parameters of LV function and LVA size could predict the choice of surgical technique.
  
  
  METHODS
  33 patients with LVA underwent EVP: 18 with patch (group A), 15 without patch (group B). Echocardiography was performed before and after surgical procedure. LVA-area, LVA-volume, its proportion to LV area and volume (LVA-area/LV-EDA, LVA-volume/LV-EDV) were determined apart from routine parameters of LV function.
  
  
  RESULTS
  Mean LVA-area was 15 cm2, LVA-volume was 50 mL. Mean LVA-areal LV-EDA was 0.38 LVA-volume/LV-EDV was 0.35. LVA exceeding 0.4 of LV area/volume was considered as a large. After surgery LV-EDV diminished +/- 40 mL, LVLd decreased +/- 1.5 cm. EF improved from 44% to 54%. Patients in group A had larger LVA-volume (60 vs 39 ml, p = 0.02) as well as LV-EDV (160 vs 120 ml, p = 0.03), and lower EF (41% vs 51% p = 0.002). Only 2 patients with LVA-volume greater than 56 ml were operated on without patch. After surgery echocardiographic parameters did not differ between the groups: in group A operation was much more extensive.
  
  
  CONCLUSIONS
  1.) Echocardiographic parameters concerning size (LVA-area, LVA-area/LV-EDA) and volume (LVA-volume, LVA-volume/LV-EDV) of LVA provides information about disturbances in LV geometry, are valuable in planning operative method. 2.) EVP with or without patch provides significant improvement of LV geometry and function in echocardiographic investigation.
