Why the study?
Does mitral valve repair improve outcomes compared to mitral valve replacement in adults with mitral insufficiency?
Does mitral valve repair improve outcomes compared to mitral valve replacement in adults with mitral insufficiency?
Mitral valve repair is widely regarded as the optimal surgical procedure for mitral valve dysfunction, with the strongest evidence supporting its use over replacement in degenerative mitral regurgitation.
Favors repair in degenerative MR; leaves open need for RCTs in other etiologies.
Degenerative, ischemic, rheumatic and infectious (endocarditis) processes are responsible for mitral valve disease in adults. Mitral valve repair has been widely regarded as the optimal surgical procedure to treat mitral valve dysfunction of all etiologies. The supporting evidence for repair over replacement is strongest in degenerative mitral regurgitation. The aim of the present review is to summarize the data in each category of mitral insufficiency and to provide recommendations based upon this data.
