Problem

Mitral regurgitation (MR) is the most prevalent valvular heart disease in the U.S., affecting approximately 1.7% of the population. MR prevalence increases with age, rising from 0.5% among 18-44 year olds to 9.3% among those aged 75 years and older [1,2]. There are 4.1 million patients in the US with moderate to severe MR requiring treatment. However, only approximately 30,000 patients in the U.S. undergo surgery for MR each year [3]. The vast majority of patients are not treated today because of the concerns about procedural complexity and patient safety during open-heart surgery. Transcatheter mitral valve repair (TMVRep) or replacement (TMVR) offer less invasive treatment options for MR patients. However, after more than a decade of development, the field of transcatheter mitral valve therapy is still in its infancy. Many of the current TMVRep and TMVR devices have dismal clinical results.

Solution

Sutra TMVR is a percutaneous, transcatheter bioprosthetic MV replacement system that bridges the best aspects of TMVR and TMVRep approaches.
