TI  - Clinical performance of the omniscience prosthetic heart valve with Dacron sewing 
      ring.
PG  - 296-9
AB  - The Omniscience prosthetic heart valve has been clinically evaluated in 44 
      patients operated on between January and July, 1981. There were 23 aortic valve 
      replacements (AVR), 18 mitral valve replacements (MVR) and 3 double valve 
      replacements (DVR). Mean age was 48 +/- 11 years. Preoperatively, 61% patients 
      were in New York Heart Association (NYHA) functional class IV, 36% in class III 
      and 2% in class II. The hospital mortality rate was 4.5%. Actuarial freedom from 
      thromboembolic events was 97.4 +/- 2.6% (3 1/2 years of follow-up). 
      Postoperatively, 93% of the patients were in NYHA class I and 7% in class II. 
      There were 7 cases of periprosthetic leak requiring reoperation (6 AVR, 1 MVR) 
      for an overall incidence of 6.3% per patient year. In all these cases the 
      causative factor was considered to be the Dacron sewing ring. All patients 
      survived the reoperation. The actuarial survival rate was 93.9 +/- 5.9% for AVR 
      and 93.7 +/- 6.1% for MVR. These data would suggest that the Omniscience 
      prosthesis represents an acceptable device for heart valve replacement, except 
      for the high incidence of periprosthetic leakage, related to the Dacron sewing 
      ring. Recent modification of the valve-construction including a Teflon sewing 
      ring may avoid the relatively high rates of periprosthetic leakage following 
      implantation of this mechanical valve.
