Methods for graft size selection in aortic valve-sparing operations
Donald B Doty, MD, Joseph M Arcidi, MD The Annals of Thoracic Surgery Volume 69, Issue 2, Pages (February 2000) DOI: /S (99)

Fig 1 Method for restoration of aortic root dimensions in an aortic valve-sparing operation when the aortic annulus is normal, and the sinotubular junction is enlarged. A 4-to-5-mm segment of a graft the same diameter as the annulus is placed on the outside of the aorta at the sinotubular junction to reduce the inside diameter 10%. The Annals of Thoracic Surgery , DOI: ( /S (99) )

Fig 2 Method for restoration of aortic root dimensions in an aortic valve-sparing operation when the aortic annulus is normal, and the sinotubular junction is normal. A vascular graft 10% less than the diameter of the aortic annulus is used to remodel the aortic root. The Annals of Thoracic Surgery , DOI: ( /S (99) )

Fig 3 Method for restoration of aortic root dimensions in an aortic valve-sparing operation when the aortic annulus is enlarged, and the sinotubular junction is enlarged. A vascular graft 10% less than the desired diameter of the aortic annulus is used to provide 4-to-5-mm strips of fabric, which are used to support a reduction annuloplasty of five-sixths of the circumference of the LVOT (avoiding the conduction system) just below the aortic valve. The graft adjusts the diameter at the sinotubular junction. The Annals of Thoracic Surgery , DOI: ( /S (99) )
