Abstract:
Utilization of the Gelweave Valsalva graft (Terumo Vascutek, Tokyo, Japan) for David-type valve-sparing aortic root replacement was still controversial because this prosthesis did not completely reproduce the native sinus of Valsalva. We focused on the morphology of pseudo-Valsalva sinus after the reimplantation procedure and evaluated our novel crimp plication stitch from the viewpoint of morphology of Valsalva sinus at midterm follow-up periods.
