A 48-year-old man underwent aortic root remodeling for a giant aneurysm of sinus of Valsalva, 98 mm in diameter, as well as a bicuspid aortic valve. The aortic valve was defined as type 0 (L-R) according to Sievers classification and the aortic annulus was highly dilated up to 35 mm. Geometric height of the left and right cusps were 22 mm and 32 mm in diameter, respectively. Dacron straight graft of 24 mm was chosen and each tongue was then created in a 180°fashion. After completion of root reconstruction, external circular suture annuloplasty using CV-0 expanded polytetrafluoroethylene (ePTFE) was made to adjust the annulus down to 22 mm in diameter. The free margin of both cusps were centrally plicated to raise the effective height to 9 mm. Postoperative echocardiography at 2 year showed trivial aortic regurgitation but no root re-dilatation. Remodeling with external circular suture annuloplasty is a reproducible and reliable method to stabilize the root, even for the patient with a giant aneurysm of sinus of Valsalva.
