VT burden reduction
Figure 5 shows the VT episodes before and after the RF ablation. A
significant VT burden reduction after the VT ablation was observed in
the entire population. RF ablation was associated with a 91.1%
reduction in VT episodes. Before and after the RF ablation, the median
VT episodes were 3 (IQR, 2 - 9) and 0 (IQR, 0 - 1) (P<0.01),
and the number of shock therapies was 2 (IQR, 1 - 5) and 0 (IQR, 0 - 0)
(P<0.01).
