Design outcomes

Primary

Measure	Time frame
Correlation between the morphology change (e.g. AP diameter, AL-PM diameter, non-planar angle, annulus area, annulus hight) of mitral valve and long-term prognosis (progression of residual regurgitation at 12-24 months after surgery).	—

Secondary

Measure	Time frame
Degree of residual regurgitation immediately and at 12-24 months after mitral valve repair. Correlation between the site of residual mitral valve regurgitation and long-term prognosis (progression of residual regurgitation at 12-24 months after surgery). Correlation between the size of mitral annuloplasty ring and long-term prognosis (progression of residual regurgitation at 12-24 months after surgery).	—
