We report a case in which replacement of a low-profile porcine Liotta bioprosthesis was required 21 years after initial implantation. The patient underwent mitral valve replacement with a 28-mm Liotta bioprosthesis in 1985 for mitral stenosis. Twenty-one years later, severe mitral regurgitation was detected at echocardiography and mitral valve reoperation combined with tricuspid annuloplasty was successfully performed. Focal perforation of two cusps with consequent intravalvular leak on bioprosthesis was found. This is the longest durability report for a Liotta bioprosthesis in mitral position.
我们报告一例患者，在最初植入低轮廓猪源Liotta生物瓣膜21年后需要进行瓣膜置换。该患者于1985年因二尖瓣狭窄接受了28毫米Liotta生物瓣膜二尖瓣置换术。21年后，超声心动图检测到严重二尖瓣反流，成功进行了二尖瓣再次手术并联合三尖瓣环成形术。发现生物瓣膜两个瓣叶有局灶性穿孔并伴有瓣内漏。这是关于二尖瓣位Liotta生物瓣膜最长耐久性的报告。
