Why the study?
Does targeting slow conduction regions propagating into the latest zone of activation improve substrate modification in scar-related ventricular tachycardia?
Does targeting slow conduction regions propagating into the latest zone of activation improve substrate modification in scar-related ventricular tachycardia?
Targeting slow conduction regions propagating into the latest zone of activation, rather than just late potentials in the latest isochrone, may be a promising novel strategy for VT substrate modification.
Questions reliance on late potentials in latest isochrone for VT ablation; leaves open whether slow conduction targeting improves substrate modification.
Late potentials identified in the latest isochrone of activation during sinus rhythm are infrequently correlated with successful ablation sites for VT. The targeting of slow conduction regions propagating into the latest zone of activation may be a novel and promising strategy for substrate modification.
