Exit block within the isolated area and long-term successsurrogate

Core isolation is a novel ablation strategy that targets suspected VT isthmus surrogates to achieve exit block, potentially improving long-term success in patients with multiple or unmappable scar-based VTs.

Resumen

CI is a novel strategy with a discrete and measurable end point beyond VT inducibility to treat patients with multiple or unmappable VTs. The CI region can be selected based on standard characterization of suspected VT isthmus surrogates thus limiting ablation target size. Exit block within the isolated area is achievable in most and may further improve long-term success.
