In aortic stenosis the valve is most often bicuspid with a single fused commissure, either the intercoronary or right and noncoronary commissure. Less frequently, it is unicommissural, with an orifice at the left and noncoronary commissure (1). The course of left-sided disease is quite different from that of the right side. Again we well refer to the natural history study to review outcomes with aortic stenosis (2).
