Key result
Valve-sparing root replacement with subvalvular annuloplasty provides standardized physiological reconstruction for aortic root aneurysms.
Why the study?
Recent international guidelines mention aortic annuloplasty combined with aortic root remodeling as part of a class I indication for aortic root aneurysm management.
Case Report (n=2)
Describes a standardized surgical technique for aortic valve and root repair using the remodeling technique combined with external aortic ring annuloplasty.
May support physiological valve-sparing repair in aortic root aneurysms; leaves open durability and outcome validation in prospective cohorts.
Recent international guidelines on the management of aortic root disease mention “aortic annuloplasty” in combination with aortic root remodeling as part of a class I indication for management of aortic root aneurysm (1). The remodeling technique provides physiological cusp movement within three reconstructed neo-sinuses, which permits root expansibility through the interleaflet triangles. We have developed a standardized aortic valve and root repair protocol involving a physiological reconstruction of the aortic root using the remodeling technique, cusp effective height resuspension, and a subvalvular external aortic ring annuloplasty (Figure 1).

Youssefi et al. (2019) conducted a case report in Aortic root aneurysm and aortic insufficiency (n=2). Valve-sparing root replacement with remodeling technique and subvalvular annuloplasty was evaluated. Valve-sparing root replacement using the remodeling technique and subvalvular annuloplasty provides a standardized physiological reconstruction for patients with tricuspid or bicuspid aortic root aneurysms.
