We want to share our experience of Sorin Bicarbon prosthesis (SBP) after 19 years follow-up.
Retrospective study of 1377 patients who had replaced with SBP from May 1998 to December 2008 at Ho Chi Minh Heart Institute, Viet Nam.
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.
SBP had shown very good results in long term and still have a reliable mechanical valve.
我们希望分享索林双叶机械瓣（SBP）19年随访的经验。
对1998年5月至2008年12月在越南胡志明心脏研究所接受SBP置换的1377例患者进行回顾性研究。
男性患者占42%，平均年龄为40.2±11.8岁。房颤发生率为43.5%。瓣膜疾病的主要病因是风湿热（89.8%）。单纯二尖瓣置换（MVR）：54%（744例），单纯主动脉瓣置换（AVR）：18%（247例），双瓣置换（DVR）：26%（359例），以及27例AVR加二尖瓣修复。所有患者的30天死亡率为1.5%。平均随访时间为153±53.1个月，总随访时间为17563患者年。2.5%的患者失访。晚期死亡77例。因各种原因再次手术59例。19年生存率为88.8±1.8%。19年无再次手术率为76.4±4.7%。所有瓣膜血栓形成、栓塞、严重出血、心内膜炎和血管翳的线性化发生率分别为0.31%、0.28%、0.267%、0.068%和0.165%患者年。
SBP长期显示出非常好的效果，仍然是一种可靠的机械瓣膜。
