TI  - Factors influencing the efficacy of DeVega's annuloplasty for secondary tricuspid 
      regurgitation.
PG  - 123-8
AB  - DeVega's annuloplasty was performed on 41 patients with tricuspid regurgitation 
      (TR) associated with combined valvular disease and results were assessed based on 
      Doppler echocardiographic findings in an attempt to examine the applicability of 
      this surgical technique. TR was quantitatively evaluated via Doppler 
      echocardiography before and after surgery. Clinical symptoms, cardiac function, 
      and surgical results were assessed, and the severity of left ventricular 
      myocardial degeneration was determined using electron microscopy. There were no 
      differences in the following factors between the TR recurrence and TR improvement 
      groups: previous heart surgery, number of involved valves, presence or absence of 
      a giant left atrium, preoperative New York Heart Association (NYHA) functional 
      class, and type of prosthetic valve (Bjork-Shiley vs. St. Jude Medical). We found 
      no differences between these two groups in TR severity and tricuspid annulus 
      diameter measured during surgery. Severity of myocardial degeneration was closely 
      associated with the recurrence of TR. Clinically, most had diminished cardiac 
      function before surgery. DeVega's technique appears to be remarkably effective in 
      patients with well-preserved myocardium because no TR recurrence was detected 
      even in examinations with the most accurate Doppler echocardiography. However, 
      such long-term effectiveness of DeVega's technique cannot be expected in patients 
      with degenerated myocardium.
