Technique for aortic valve annuloplasty using an intra-annular “hemispherical” frame J. Scott Rankin, MD, L. Alan Beavan, MSE, William E. Cohn, MD The Journal of Thoracic and Cardiovascular Surgery Volume 142, Issue 4, Pages 933-936 (October 2011) DOI: 10.1016/j.jtcvs.2011.01.039 Copyright © 2011 The American Association for Thoracic Surgery Terms and Conditions

Figure 1 A, Photograph of a prototype “hemispherical” annuloplasty frame. B, Vertical incisions in the commissures on either side of the right coronary cusp (yellow arrows). See text for details.

Figure 2 A, Three frame posts were first sutured to the subcommissural regions to orient the device vertically and horizontally. B, After insertion, looping horizontal mattress sutures were placed around the body of the frame and then vertically through the valve annulus. After all sutures were placed, they were tied over small custom-designed Dacron pledgets that were narrow enough not to extend out to the leaflet tissue. Initially, small bites of Dacron were taken, but the method seemed to work better (and proceed faster) with just looping of the frame, eliminating the Dacron bites. C, View of the implanted valve from above with most of the aorta cut away. Leaflets are symmetric with good coaptation and vertical position. D, View of the valve from below after pressurization showing good frame position and cusp coaptation after restoration of leaflet geometry.

Figure 3 A, View of the explanted calf aortic valve from above at 6 weeks after frame insertion with the technique described. The leaflets were symmetric with good coaptation and vertical position. B, View of the valve from below showing good frame position and endothelialization/healing of the device with competent leaflets.
