Sinotubular junction size in aortic valve reimplantation procedures is usually predetermined on the basis of mathematical calculations and intraoperative measurements. We propose a new method for aortic valve reimplantation by which intraoperative measurements can be eliminated and sinotubular junction size adjusted after cross clamp removal to fit the patient’s need. Aortic valve commissures are reimplanted in the expandable skirt of a Valsalva (Vascutek, Renfrewshire, Scotland) graft to realize an oversized sinotubular junction that is subsequently reduced to the proper size by wrapping, with Dacron rings of decreasing size, the neo-sinotubular ridge under transesophageal echocardiographic guidance.
