We present our initial experience in 10 patients operated on using a modified Ross operation. In our modification of the Ross operation the pulmonary autograft root was inserted in the Gelweave Valsalva graft to prevent dilatation of the neoaortic root. This type of graft was selected to match the discrepancy between diameters of the annulus and the sinotubular junction of the autograft and to preserve the characteristic configuration of the native root. In our group of 10 patients operated consecutively by this technique there was no change in the geometry of the neoaortic root in the follow-up 3–19 months (mean 14.6 months).

Key Words: Aortic root • Aortic valve replacement • Ross operation
