TI  - Long-term experience with the Sorin Bicarbon and Edwards Mira mechanical valve 
      prostheses in the mitral position.
PG  - 91-7
AB  - OBJECTIVE: Sorin Bicarbon (SB) and Edwards Mira (EM) valves have an identical 
      mechanical design but different sewing cuffs. The purpose of this retrospective 
      study was to analyze the long-term clinical and echocardiographic outcomes after 
      mitral valve replacement with these two valves in a combined population of 
      patients. METHODS: We retrospectively reviewed records of 73 patients who 
      underwent mitral valve replacement using SB (n = 19) or EM (n = 54) valves. 
      Preoperatively, 49 patients (68.1%) were in New York Heart Association (NYHA) 
      functional class III or IV. Concomitant procedures were performed in 52 patients 
      (71.2%). Early and late postoperative echocardiography was performed in 69 and 57 
      patients, respectively. RESULTS: Operative mortality was 4.1%, and early 
      morbidity was 9.6%. Overall patient survival at 9 years was 85.1% +/- 4.8%. 
      Actuarial freedom from valve-related death was 95.4% +/- 2.6% at 9 years. As 
      shown by Doppler echocardiography, the early and late mean transprosthetic 
      pressure gradients were 3.4 +/- 1.4 mmHg and 3.8 +/- 2.1 mmHg, respectively. At 
      the end of follow-up, 98.4% of survivors were in NYHA class I or II. CONCLUSION: 
      The Sorin Bicarbon and, Edwards Mira mechanical valves in the mitral position 
      provide satisfactory long-term clinical and echocardiographic performance.
