1 A new technique for aortic valve dysfunction: reconstruction by posterior leaflet of tricuspid valve 
Hansong Sun, MD, Qiang Wang, MD, Shengshou Hu, MD, Yinglong Liu, MD, Liqing Wang, MD, Ge Gao, MD  The Annals of Thoracic Surgery  Volume 78, Issue 1, Pages (July 2004) DOI: /S (03)

2 Fig 1 Surgical technique used to obtain the posterior leaflet of tricuspid valve and tricuspid valvuloplasty. (a) The posterior leaflet will be excised. (b) Annuloplasty is performed with a pledgetted suture and the leaflets are reapproximated using 5-0 suture. The Annals of Thoracic Surgery  , DOI: ( /S (03) )

3 Fig 2 Surgical technique used to reconstruct a “new” aortic noncoronary leaflet and sinus of Valsalva. (a) Morphologic feature in the first patient with aortic bicuspid valve and moderate commissural fusion. Broken lines show the new corresponding positions of both cusps. (b) New cusp is sutured between commissure A and B with 5-0 polypropylene suture. The Annals of Thoracic Surgery  , DOI: ( /S (03) )

4 Fig 3 Surgical technique used to establish “new” left and right coronary leaflets. (a) Incision is made on the bigger cusp, beginning at the point AA' of the one-quarter length of the free edge from the anterior commissure, extending inferiorly to the point CC' at the base of the leaflet and continuing to the point D. (b) The incised free edge (A′-C′-D) is refixed to aortic wall forming a new aorta annula (D-C′-BA′). The new commissure “point BA′” is composed of point B and A′ incised from AA′. (C) The deficient area of the right coronary leaflet is treated with the posterior leaflet of tricuspid valve. The Annals of Thoracic Surgery  , DOI: ( /S (03) )

5 Fig 4 Surgical technique used to reconstruct “new” left and right coronary leaflets. (a) Morphologic feature in the second patient with aortic bicuspid valve and severe corresponding leaflet prolapse. Broken lines (D-B) show the new corresponding position of “new” left coronary leaflet. (b) “New” left and right coronary leaflets are reconstructed using the posterior leaflet of tricuspid valve. “!” (The area composed with A-C-A′B) represents the material of the posterior leaflet. The new commissure “point A′B” is composed of point Band A′ incised from AA′. The Annals of Thoracic Surgery  , DOI: ( /S (03) )
