resonance imaging with late gadolinium enhancement (LGE)
may identify slowly conducting tissues in scar-related
ventricular tachycardia (VT). OBJECTIVE: To test the
feasibility of image-based simulation based on LGE to
estimate ablation targets in VT. METHODS: We conducted a
retrospective study in 13 patients who had preablation
magnetic resonance imaging for scar-related VT ablation.
We used image-based simulation to induce VT and estimate
target regions according to the simulated VT circuit. The
estimated target regions were coregistered with the LGE
scar map and the ablation sites from the electroanatomical
map in the standard ablation approach. RESULTS: In
image-based simulation, VT was inducible in 12 (92.3\%)
patients. All VTs showed macroreentrant propagation
patterns, and the narrowest width of estimated target
region that an ablation line should span to prevent VT
recurrence was 5.0 +/- 3.4 mm. Of 11 patients who
underwent ablation, the results of image-based simulation
and the standard approach were consistent in 9 (82\%)
patients, where ablation within the estimated target
region was associated with acute success (n = 8) and
ablation outside the estimated target region was
associated with failure (n = 1). In 1 (9\%) case, the
results of image-based simulation and the standard
approach were inconsistent, where ablation outside the
estimated target region was associated with acute success.
CONCLUSIONS: The image-based simulation can be used to
estimate potential ablation targets of scar-related VT.
The image-based simulation may be a powerful noninvasive
tool for preprocedural planning of ablation procedures to
potentially reduce the procedure time and complication
rates.",
