**8. Conclusions**

MS as the long-standing sequel of RHD is rare in developed countries, whereas it is still seen frequently in many areas of the world. BMV as a minimally invasive transcatheter technique is the method of choice in the treatment of these patients. In successful cases, BMV results in a very high survival rate and freedom from symptoms. Appropriate patient selection and a competent technique are the key factors for achieving an excellent result.
