Impedance drop predicts acute electrical reconnection of the pulmonary vein-left atrium after pulmonary vein isolation using short-duration high-power exposure.
To determine the efficacy and identify the relevant factors for durable lesion creation in pulmonary vein isolation (PVI) using a high-power short-duration (HPSD) strategy. ⋯ The HPSD strategy reduced RF time, RF energy, and three-dimensional mapping-related indices but also improved the acute outcome. The HP strategy may be a sophisticated strategy under guidance with the impedance drop rather than the ablation index.
