title: Ross procedure with a composite autograft using stretch Gore-Tex material.
abstract: In an attempt to allow physiologic expansion of the pulmonary autograft, yet limit late root dilation, we used stretch Gore-Tex material (W. L. Gore & Assoc, Flagstaff, AZ) as an external wrap. Follow-up cardiac computed tomography with reconstructed three-dimensional and dynamic images confirmed normal "triple bulge" sinus Valsalva geometry and preserved natural systolic expansion of the neoaortic root.
