Abstract

Atrial fibrillation is a common arrhythmic disorder that increases the risk of cardiovascular events. Catheter ablation for atrial fibrillation is an effective treatment option but is not widely practiced in Vietnam due to prolonged procedure times and lower success rates compared to other arrhythmias. The use of a force-sensing catheter during AF ablation has been studied to improve the procedure's efficacy by allowing control over the applied force during the ablation process. Objective: The objective of this study was to evaluate the initial safety and efficacy of the force-sensing catheter in atrial fibrillation ablation. Safety was assessed based on early complications post-procedure. Efficacy was evaluated by the rate of pulmonary vein isolation, procedure time, fluoroscopy time, and the duration and number of ablation points. Method: This study employed a cross-sectional descriptive design, involving 27 patients diagnosed with atrial fibrillation who underwent catheter ablation using a force-sensing catheter. Result: The mean age of the patients was 54.59 ± 10.48 years, with 77.8% being male. The left atrial size was within normal limits or mildly dilated. The average procedure duration was 170.56 ± 28.80 minutes, with an average fluoroscopy time of 12.30 ± 4.23 minutes. The average ablation time was 2305.74 ± 709.98 seconds, with an average of 62.52 ± 13.50 ablation points. All patients completed the procedure with sinus rhythm and achieved complete electrical isolation of the four pulmonary veins. No significant complications were observed using the force-sensing catheter during the ablation procedure. Conclusion: The study demonstrates that the force-sensing catheter is both safe and effective for atrial fibrillation ablation, highlighting its potential for broader application in the treatment of atrial fibrillation in Vietnam.
