Impedance mapping with constant contact force on 3D electroanatomic map to characterize tissues at pulmonary veno-atrial junction

ConclusionsIm mapping of LA-PVJ at constant CF added to 3DEAM may consistently track the tissue transition from PV to LA. PVan identified by Im was often located more toward LA than the 3D anatomical PVan, particularly in LSPV, suggesting the potential advantage of avoiding ablation of venous-like tissue. Im mapping can deserve further investigation for target characterization at LA-PVJ.
