TI  - Preoperative M-mode echocardiography as a predictor of surgical results in 
      chronic aortic insufficiency.

AB  - A group of 80 patients were studied retrospectively to determine whether 
      preoperative echocardiography is useful in predicting operative results in 
      patients with aortic valve replacement for chronic aortic insufficiency. One year 
      after operation, percent change of left ventricular dimension (%delta D) and 
      ejection fraction (EF) were higher and end-systolic left-ventricular internal 
      dimension was smaller in patients with good results than in those who had poor 
      results (p less than 0.05). Regarding probability of 5 year survival, patients 
      with a %delta D of more than 35% had good prognosis, those with 31% to 35% had a 
      fairly good prognosis, and those with 30% or less had increased risk of death, 
      especially if they were in New York Heart Association (NYHA) Functional Class III 
      or IV. All deaths occurred in patients with preoperative values of 31% or less. 
      Patients with EF of 60% or more had a better prognosis than those with a value of 
      less than 60%. In addition, 10 early postoperative echocardiographic studies 
      showed no correlation between early regression of end-diastolic left ventricular 
      internal dimension and long-term operative results; 18 late postoperative studies 
      showed reduction in this dimension in patients with good surgical results, and 
      the only one with a poor result had an enlarged dimension. Thus echocardiographic 
      indices of left ventricular function (%delta D) and EF) may be useful as 
      prognostic indicators in patients undergoing aortic valve replacement for aortic 
      insufficiency.
