Key result
In a 19-year follow-up of 1,377 patients, the Sorin Bicarbon prosthesis demonstrated an 88.8% overall survival rate and a 76.4% freedom from reoperation rate.
Why the study?
The authors sought to evaluate long-term outcomes and share their 19-year institutional experience with the Sorin Bicarbon prosthesis.

What are the long-term survival and complication rates of the Sorin Bicarbon mechanical prosthesis in patients undergoing valve replacement?
The Sorin Bicarbon mechanical prosthesis demonstrates excellent long-term durability and survival up to 19 years, though adequate anticoagulation monitoring is critical to prevent valve thrombosis.
Supports durability of Sorin Bicarbon in valve replacement; extends observational data but leaves randomized comparisons open.
PURPOSE: We want to share our experience of Sorin Bicarbon prosthesis (SBP) after 19 years follow-up. METHODS: Retrospective study of 1377 patients who had replaced with SBP from May 1998 to December 2008 at Ho Chi Minh Heart Institute, Viet Nam. RESULTS: Male patients was 42%, mean age was 40.2 ± 11.8 years. Atrial fibrillation was 43.5%. The main cause of valvular disease was rheumatic fever (89.8%). Isolated mitral valve replacement (MVR): 54% (744), isolated aortic valve replacement (AVR): 18% (247), double valve replacement (DVR): 26% (359), and 27 AVR plus mitral repair. 30-day mortality for all was 1.5%. Mean time of follow-up was 153 ± 53.1 months with total follow-up time was 17563 patients-years. 2.5% lost of follow-up. Late death was 77 cases. Redo for all causes was 59 cases. 19 years survival was 88.8 ± 1.8%. 19 years freedom of redo was 76.4 ± 4.7%. Linearized rate of all valve thrombosis, embolism, severe bleeding, endocarditis, and pannus were 0.31%, 0.28%, 0.267%, 0.068%, and 0.165% patient-years, respectively. CONCLUSIONS: SBP had shown very good results in long term and still have a reliable mechanical valve.

Hung Dung Van (2019) conducted a cohort in Valvular heart disease (n=1,377). Sorin Bicarbon prosthesis was evaluated on 19-year overall survival. In a 19-year follow-up of 1,377 patients, the Sorin Bicarbon prosthesis demonstrated an 88.8% overall survival rate and a 76.4% freedom from reoperation rate.
