Implication

May aid preprocedural planning in VT ablation; hypothesis-generating and requires randomized confirmation before practice change.

Key Points

To evaluate whether 3D scar reconstruction using images from a 3D gradient-recalled echo (3D-GRE) sequence improves conducting channel delineation prior to ventricular tachycardia ablation.
Acquired 3D gradient-recalled echo (3D-GRE) delayed-enhanced magnetic resonance images to generate 3D reconstructions of myocardial scar tissue prior to ventricular tachycardia ablation.
3D scar reconstruction using images from the 3D-GRE sequence improved the overall delineation of conducting channels prior to ventricular tachycardia ablation.
High-resolution 3D visualization facilitated clearer anatomical identification of potential arrhythmogenic substrate channels within scar tissue.

Structured PICO
