“…Preserving the autograft in the aortic position is the ideal solution for patients with moderate autograft dilatation, central regurgitation, symmetric cusps, and a wellfunctioning pulmonary allograft. 1,18,19,[21][22][23] A valvesparing operation to preserve the autograft in the aortic position is not always feasible in patients with valve degeneration, which is a common pathologic finding regardless of the technique used for the Ross procedure. 1,6,10,15,[23][24][25][26] Often, neither the autograft root nor the cusps are symmetrical, and tissue surrounding the autograft is asymmetrically distributed.…”
