Narrow mitral annulus is a common situation faced in adult patients. Choice of prosthetic valve in such cases is unclear. There are reported experiences with supra-annular mitral valve, Manouguian technique, "chimney technique" with mechanical valve and Melody valve, the latter two being in children. We report a novel "bio-chimney" technique in which a bioprosthetic valve of a size appropriate for the patient is sutured to a polyester vascular graft, which is then implanted to the native narrow mitral annulus in an adult patient, with promising initial results.
二尖瓣环狭窄在成年患者中较为常见。在这种情况下，选择人工瓣膜并不明确。目前已有关于瓣上二尖瓣、马努圭安技术、机械瓣“烟囱技术”和 Melody 瓣膜的报道，后两种技术用于儿童。我们报告了一种新的“生物烟囱”技术，即将适合患者的生物瓣缝合到聚酯血管移植物上，然后将其植入成年患者的原生二尖瓣环，初步结果令人满意。
