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 648-650 (February 2000) DOI: 10.1016/S0003-4975(99)01481-2

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 2000 69, 648-650DOI: (10.1016/S0003-4975(99)01481-2)

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 2000 69, 648-650DOI: (10.1016/S0003-4975(99)01481-2)

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 2000 69, 648-650DOI: (10.1016/S0003-4975(99)01481-2)
