Figure 2 Traditional ring annuloplasty versus the extended De Vega stitch technique(A) Ring annuloplasty provides annular reduction, remodeling and rigid annular stabilization. It requires prolonged anticoagulation. (B) Original De Vega suture annuloplasty (C) The modified (extended) De Vega suture annuloplasty achieves effective annular reduction, remodeling while preserving three-dimensional physiologic annular motion and avoiding the need for prosthetic material and anticoagulation.
