二尖瓣反流诊治进展

Recent Progress in Diagnosis and Treatment of Mitral Regurgitation

影响二尖瓣关闭功能的疾病都可以导致二尖瓣反流。轻度二尖瓣反流患者仅有轻微劳力性呼吸困难,重度二尖瓣反流症状严重,降低患者的生存时间。目前依据病因可将二尖瓣反流分为原发性二尖瓣反流和继发性二尖瓣反流,这两种二尖瓣反流有不同的诊断和治疗原则。现就二尖瓣反流的诊断治疗进展做一综述。

The diseases that affect the function of mitral valve can lead to mitral regurgitation（ MR）. The patients with mild MR can only feel mild exertional dyspnea and the patients with severe MR can feel severe symptoms,which reduces the patients＇ survival time. Presently,MR is classified into primary and secondary entities based on the pathogen. The diagnosis and treatment of the primary and secondary MR are quite different. This paper aims to make a comprehensive review about the recent progress in diagnosis and treatment of MR.
