由于二尖瓣及周围心腔组织结构复杂，介入微创治疗二尖瓣技术起步较晚，目前，仅二尖瓣叶夹合技术（Mitraclip）在少数发达国家有选择性的应用治疗二尖瓣反流。但是，此类技术发展迅速，如今已有多种不同类型的介入微创治疗二尖瓣处在不同的研究阶段。本文对这些介入微创治疗二尖瓣反流的技术作一综述。

Due to the complex structure of mitral valve and its surrounding tissues, technique of minimally invasive treatment of mitral valve diseases was started late. At present, only Mitraclip technique is selectively used in some developed countries to treat mitral regurgitation. However, new technologies have leaped forward. Nowadays, various prototypes of minimally invasive treatment of mitral valve diseases are in different stages of experimental or preclinical study. In this review, these technologies of minimally invasive treatment are summarized.
