The difference in procedure time will be substantial. Right now most of the time spent on a VT ablation is for mapping the rhythms and scar. We can pretty much eliminate that (trials ongoing), meaning the procedure can be cut from 4-12 hours down to 2-3 hours, reliably.
Considering the cost of time in the EP lab, the savings can be quite large.
When it comes to ICDs, risk stratification is really important. If we can avoid putting in unnecessary devices which cost (not counting implantation) $25k-$55k, that's a big savings.
