For Biosense Webster, Inc. employees and Health Care Professionals in Europe only. Prior to use, refer to the instruction for use supplied with this device for indications, contraindications, side effects, suggested procedure, warnings and precautions. The CARTO VISITAG? Module provides access to data collected during the application of RF energy; The method gives a different weight to the parameters. The data does not indicate the effectiveness of RF energy application. Always verify catheter tip location using fluoroscopy or IC signals and consult the CARTO? System User Guide regarding recommendations for fluoroscopy use. Catheter advancement should be done under fluoroscopic guidance. Do not use excessive force to advance or withdraw the catheter when resistance is encountered. Careful catheter manipulation must be performed in order to avoid cardiac damage, perforation, or tamponade. RF parameters you may find in this session provide conceptual information that does not intent to reflect parameters used in clinical practice (such as Power, impedance, temperature, contact force). ;Topics;Scientific Background;Purpose To measure the effects of varying the Force-Power-Time Index (FPTI: grams x Watts x seconds) on RF lesion size and incidence of steam pop in the beating heart of canine model Experiment was performed using THERMOCOOL SMARTTOUCH? Catheter. ;Ablation Protocol;Example of RF Parameters during Ablation;Demo Lesions;Force-Power-Time Index vs. Lesion Depth;Lesion Depth by Time for Variable Power and Contact-Force ;Integrated RF Parameters Indexing;Ablation Index Formula versus Actual Lesion Depth ;Can Ablation Index Formula predicts Lesion Size Purpose To determine whether the Force-Power-Time Index Formula could be used prospectively to create RF lesions at predicted depths of 3 mm, 5 mm, 7 mm and 9 mm in the beating canine right and left ventricles ;Study Protocol;Depth Prediction Target lesion depth 5 mm in canine model;Exemple of Graph Di
