Three @entity1 with far-advanced @entity39 of the aorta, which had produced @entity1283 of the aortic root and severe @entity337 , were operated on using a procedure not previously described. Measurements of the aortic valve annulus and ascending aorta were made from aortograms. A knitted polyester arterial prosthesis was sewn together to form a circle. This circular prosthesis was sewn to a 31 mm Bj  rk-Shiley aortic valve prosthesis in the way that a tire is fitted onto a wheel. The resulting composite prosthesis, which had the same diameter as the aortic root, was used to replace the excised valve. In all cases a composite prosthesis measuring greater than 50 mm in diameter was used. In 2 of the 3 @entity1 the ascending aorta was replaced with a tubular graft reshaped as a truncated cone. This reshaping was done by inserting multiple gussets into one end of the aortic prosthesis so that the flanged end fit precisely to the transverse aortic arch. Two @entity1 are asymptomatic more than two years following operation. The third @entity1 died suddenly of a @entity943 on the twenty-third postoperative day.

A new operation for far-advanced XXXX of the aortic root.
