Abstract：
As the general population ages, the incidence of degenerative mitral stenosis (MS) among patients has increased. Percutaneous mitral valvuloplasty (PMV) has emerged as a well-established option for mitral rheumatic stenosis with specific characteristics. However, a blank therapeutic space must be filled with the treatment options for degenerative or rheumatic mitral stenosis in patients with many comorbidities and contraindication for valvuloplasty. We here present a comprehensive overview of the current possibilities, despite their scarce success. That is the reason why we propose a case series to facilitate a better understanding of our innovative technique in this challenging clinical context.
摘要：
随着人口的老龄化,患者中退行性二尖瓣狭窄(MS)的发生率增加.经皮二尖瓣成形术（PMV）已成为具有特定特征的二尖瓣风湿性狭窄的公认选择。然而,对于有许多合并症和瓣膜成形术禁忌症的退行性或风湿性二尖瓣狭窄患者，必须填补空白的治疗空间。我们在这里全面概述当前的可能性，尽管他们很少成功。这就是为什么我们提出一个案例系列，以促进在这个具有挑战性的临床背景下更好地理解我们的创新技术。
