1 Aortic Valve Reconstruction of Unicuspid Aortic Valve by Tricuspidization Using Autologous Pericardium  Isamu Kawase, MD, Shigeyuki Ozaki, MD, PhD, Hiromasa Yamashita, MD, Shin Uchida, MD, Yukinari Nozawa, MD, Takayoshi Matsuyama, MD, Mikio Takatoh, MD, So Hagiwara, MD  The Annals of Thoracic Surgery  Volume 94, Issue 4, Pages (October 2012) DOI: /j.athoracsur Copyright © 2012 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Excised aortic valve. Only 1 area of valve orifice opening reaches the annulus. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2012 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 Creation of new commissure. Newly created commissure is marked at a higher position—the same height of sole existing commissure along the raphe. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2012 The Society of Thoracic Surgeons Terms and Conditions

4 Fig 3 Shape of pericardial leaflet on template. It is designed to have annular zone and coaptation zone with margin to seam. Its free-edge length is proportional to distance between each commissure.

5 Fig 4 Completion of aortic valve reconstruction. Commissural height is equalized as the height of sole preexisting commissure. (LCC = left coronary cusp; NCC = non coronary cusp; RCC = right coronary cusp.)

6 Fig 5 Difference of total free-edge length of tricuspid and unicuspid aortic valves. Total length of free edge of unicommissural unicuspid aortic valve (red line) is shorter than total length of free edge of tricuspid aortic valve (blue line). (LCS = left coronary sinus; NCS = non coronary sinus; RCS = right coronary sinus.)
