Abstract:BackgroundPrecise mapping of the Purkinje fiber network is essential in catheter ablation of Purkinje‐related ventricular arrhythmias (PrVAs). We sought to evaluate the mapping ability of a multi‐spline duodecapolar catheter (PentaRay) for PrVAs.MethodsMappings of Purkinje fibers by PentaRay catheters were compared with those by conventional mapping catheters in consecutive patients undergoing catheter ablation of PrVAs from 2015 to 2022.ResultsSixteen PrVAs (7 premature ventricular contractions or non‐reentra… Show more
