Cutting or trimming the leaflets would require a valvulotome, and there is currently no valvulotome on the market in the US for this.

The valve is like a seal covering the opening. If you stretch a rubber seal it will bounce back.
My right jugular is patent now for 7 months with no further intervention on that side. I don't know how long it will stay patent. I would be really surprised if it never required another ballooning.
It might just be the reality that CCSVI treatments need to be repeated, if not in everyone then certainly in some of us. This is a harsh reality if one is paying out-of-pocket for the procedure. But then again we have MS, we are familiar with harsh realities.
Even in June 2010, IRs were doing angioplasty on the area of the valves since that is where the narrowings mostly were. Even if the IR didn't know it was a valve, it was still narrowed, and it was where he ballooned.
I agree about the learning curve and the too-high price that has been paid.
