Suture Annuloplasty and Simplified Root Wrapping in the Full Root Ross Operation

This report describes our reinforcement technique for the free-standing autograft in the full root Ross operation, using external suture annuloplasty and simplified root wrapping with native aortic wall. After implantation of the autograft in the aortic annulus, an expanded polytetrafluoroethylene suture is fixed outside the root at the basal plane and tied around a Hegar dilator placed into the autograft. By including the tongues of aortic root tissue at the distal anastomosis of the autograft, three tongues of original root wall lie outside the autograft commissures. This technique preserves autograft valve geometry and provides sufficient reinforcement of the free-standing autograft.
