BACKGROUND The combination of contact force (CF) and local impedance (LI) may improve tissue characterization and lesion prediction during radiofrequency (RF) ablation. OBJECTIVE To evaluate the utility of LI combined with CF in assessing radiofrequency ablation efficacy. METHODS A LI catheter with CF-sensing was evaluated in swine (n=11) and in vitro (n=14). The relationship between LI and CF in different tissue types was evaluated in vivo. Discrete lesions were created in vitro and in vivo at a range of forces, powers, and duratio
