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.
