理性选择机械瓣膜和生物瓣膜

Rational Choice of Mechanical and Bioprosthesis Valve

人工心脏瓣膜置换是严重瓣膜病变的主要外科治疗手段之一。机械瓣膜因耐久性好、无需再次手术等优点而广泛应用。随着医疗技术的进步,生物瓣膜因无需终身抗凝、使用寿命长等优势冲击着机械瓣的应用地位。然而,如何正确地选择人工瓣膜种类,尤其是对于55~65周岁的患者如何把握生物瓣的使用仍是困扰外科的一大难题,本文就如何理性选择人工瓣膜种类提供更有效、更科学的依据。

Heart valve replacement is the major surgical treatment of severe valvular diseases. Due to the durability and reoperation-free, mechanical valves are widely used. Bioprosthesis valves became popular recently because of long service life and no demand for lifelong anticoagulation. However, how to choose the appropriate prosthetic heart valves, especially the application of bioprosthesis valves for patients at 55 to 65 years is still a major problem. This review focuses on more effective and scientific basis for rational choice of mechanical and bioprosthesis valve.
