dc.description.abstract [EN] Purpose While the standard setting during radiofrequency catheter ablation (RFCA) consists of applying low power for long times, a new setting based on high power and short duration (HPSD) has recently been suggested as safer and more effective. Our aim was to compare the electrical and thermal performance of standard vs. HPSD settings, especially to assess the effect of the catheter orientation. Methods A 3D computational model was built based on a coupled electric-thermal-flow problem. Standard (20 W-45 s and 30 W-30 s) and HPSD settings (70 W-7 s and 90 W-4 s) were compared. Since the model only included a cardiac tissue fragment, the power values were adjusted to 80% of the clinical values (15, 23, 53 and 69 W). Three catheter-tissue orientations were considered (90 degrees, 45 degrees and 0 degrees). Thermal lesions were assessed by the Arrhenius equation. Safety was assessed by checking the occurrence of steam pops (100 degrees C in tissue) and thrombus formation (80 degrees C in blood). Results The computed thermal lesions were in close agreement with the experimental data in the literature, in particular with in vivo studies. HPSD created shallower and wider lesions than standard settings, especially with the catheter at 45 degrees. Steam pops occurred earlier with HPSD, regardless of catheter orientation. Conclusion HPSD seems to be more effective in cases that need shallow and extensive lesions, especially when the catheter is at 0 degrees or at 45 degrees, as used in pulmonary vein isolation. es_ES
