Acute failure of catheter ablation for ventricular tachycardia due to structural heart disease: causes and significance.

In the patients who did not have a postablation attempt to reinduce VT, all‐cause mortality ( P <0.001, Figure 4 ) and 1‐year recurrence ( P =0.08, Figure 5 ) rates were greater than in those with ablation success, although the latter did not reach statistical significance.
