PG - 275-80 AB - Clinical data on the Omniscience cardiac valve prosthesis (sizes 19 to 31 mm) were obtained from 326 patients (155, aortic valve replacement [AVR]; 125, mitral valve replacement [MVR]; and 46, double-valve replacement) during a five-year period (650 patient-years) with 96% accountability. Mean age was 56 +/- 12 years, and 40% (130) of the patients were 61 years old or older. Thirty-one percent (101) had prior or concomitant coronary artery bypass grafting procedures, 9% (28) had a previous malfunctioning prosthesis, and 17% (57) had other cardiac surgical procedures. Eighty percent were in New York Heart Association (NYHA) Functional Class III or IV preoperatively. Early mortality was 10% (34). Five-year actuarial thrombus-free rate is 96% for patients who underwent AVR and 95% for patients having MVR. Postoperatively, 89% (172/193) were in NYHA Class I or II, and 84% (163/193) improved by at least one Functional Class. A significantly high proportion of the postoperative hematological values fall within normal ranges: red blood cell count, 94% (176/187); hematocrit, 88% (166/188); and hemoglobin, 93% (176/190). Ninety-eight percent (287/292) are free from clinical anemia. Four of the 5 patients with clinical anemia had a preoperative history of this condition. Levels of lactic dehydrogenase in 3 patients suggested the probable presence of clinically significant hemolysis, although all 3 have normal hematological values. Actuarial five-year survival for patients who underwent AVR or MVR are similar (82% and 80%, respectively), indicating satisfactory and comparable levels of safety and performance.(ABSTRACT TRUNCATED AT 250 WORDS) FAU - DeWall, R AU - DeWall R FAU - Pelletier, L C AU - Pelletier LC FAU - Panebianco, A AU - Panebianco A FAU - Hicks, G AU - Hicks G FAU - Schuster, B AU - Schuster B FAU - Bonan, R AU - Bonan R FAU - Martineau, J P AU - Martineau JP FAU - Yip, L AU - Yip L LA - eng PT - Journal Article PL - Netherlands TA - Ann Thorac Surg JT - The Annals of thoracic surgery JID - 15030100R RN - 0 (Hemoglobins) SB - IM MH - Adolescent MH - Adult MH - Aged MH - Aortic Valve MH - Erythrocyte Count MH - Female MH - Follow-Up Studies MH - Heart Valve Diseases/blood/*surgery MH - *Heart Valve Prosthesis/adverse effects/mortality MH - Hematocrit MH - Hemoglobins/analysis MH - Humans MH - Male MH - Middle Aged MH - Mitral Valve MH - Thromboembolism/etiology EDAT- 1984/09/01 00:00 MHDA- 1984/09/01 00:01 CRDT- 1984/09/01 00:00 PHST- 1984/09/01 00:00 [pubmed] PHST- 1984/09/01 00:01 [medline] PHST- 1984/09/01 00:00 [entrez] AID - S0003-4975(10)62251-5 [pii] AID - 10.1016/s0003-4975(10)62251-5 [doi] PST - ppublish SO - Ann Thorac Surg. 1984 Sep;38(3):275-80. doi: 10.1016/s0003-4975(10)62251-5.
