Figure 1 Traditional mitral valve ring annuloplasty versus the modified mitral valve stitch technique(A) Ring annuloplasty provides annular reduction, remodeling, and rigid annular stabilization. It requires prolonged anticoagulation. (B) The modified suture annuloplasty technique achieves effective annular reduction and remodeling while preserving three-dimensional physiologic annular motion. It avoids prosthetic material and anticoagulation.
