Abstract
A method, system, and device for predicting lesion quality. Specifically, lesion quality may be predicted based on an assessment of pulmonary vein occlusion using injection of an impedance-modifying agent and evaluation of changes in impedance measurements recorded by an electrode located distal to an occlusion element of the treatment device used to inject the impedance-modifying agent. The quality of the occlusion may be rated based on the changes in impedance over time within the pulmonary vein. For example, the quality of the occlusion may be rated as being good, fair, or poor. This assessment may be quickly and easily communicated to an operator.
