摘　　要：目的观察GK型双叶式人工心脏瓣膜(GK双叶瓣)植入人体后的临床疗效和近期随访结果。方法20例病人行人工心脏瓣膜替换术,其中二尖瓣替换(MVR)14例,主动脉瓣替换(AVR)4例,二尖瓣和主动脉瓣替换(MVR+AVR)2例。术后定期随访和检查是否有瓣膜相关的并发症。结果全组无死亡。无并发症,长期生存已1年至2年半。术后病人心功能均已从Ⅲ～Ⅳ级转为Ⅰ～Ⅱ级,血流动力学性能及生物相容性良好,生活质量改善。结论GK双叶瓣初步临床应用获得了满意的效果,其近期随访结果未发现与瓣膜有关的并发症。Objective To introduce a new type of bileaflet mechanical prosthetic heart valve(GK bileaflet valve)and evaluate clinically the early hemodynamic effect and short term follow up after its replacement. Methods 20 patients were operated upon with a mean age of 44.5±10.74 years. 85 percents(17/20) had NYHA class Ⅲ or IV heart function.The mitral valve relacement was performed in 14 patients, aortic valve replacement in 4 patients and double valve replacement in 2 patients. Follow-up is 100% and extended 1 to 2.5 years. Results There was no any early or late mortality. Without valve-related complications all patients have lived for more than 1 to 2.5 years. Conclusion Early clinical results and short-term followup demonstrate that GK bileaflet prosthetic heart valve exhibits excellent hemodynamic properties, satisfied blood consistency and a low incidence of valve-related complications.
