      aortic valve disease].
PG  - 327-32
AB  - The morphological and functional aspects of the left ventricle (LV) were assessed 
      by echocardiography and cardiac catheterization performed simultaneously in 41 
      patients. Eleven were normal (N), 14 had aortic stenosis (AS) and 16 had aortic 
      regurgitation (AR). Of the 14 patients with AS, eight were in New York Heart 
      Association (NYHA) functional class I and II (ASA group) and six were in NYHA 
      functional class III and IV (ASB group). Of the 16 patients with AR, seven were 
      in NYHA functional class I and II (ARA group) and nine in functional class III 
      and IV (ARB group). In the ASA group normal values of the LV function were 
      obtained because of the development of an adequate hypertrophy that in 
      normalizing the systolic stroke was able to keep a suitable function. In the ASB 
      group there was a reduction of the LV function due to an increase of the systolic 
      stroke and to the reduction of the contractile muscle state. Thus, in the whole 
      AS group we found an inversed relation between the ejection fraction and the 
      systolic stroke. In the ARA group we found a normal cardiac function as 
      consequence of an adequate development of the LV dilation and hypertrophy. 
      Despite the find of reduction of the contractile state, the systolic stroke 
      normalizing was capable to keep the cardiac function at normal values. The ARB 
      group presented an important depression of the cardiac function due the increase 
      of the systolic stroke and to the decrease of the contractile state of the 
      cardiac muscle.
