The Research Of Thermocool Smarttouch Catheter In The Treatment Of Atrial Fibrillation

Objective:The study sought to assess the safety and effectiveness of an irrigated, contact force(CF)-sensing catheter in the treatment of AF.Method:A total of 10 patients with symptomatic AF refractory to drug therapy were enrolled,either paroxysmal(n=6) or persistant(n=4).all of them underwent radiofrequency application with the contact force(CF)-sensing catheter. Ablation included pulmonary vein isolation with confirmed entrance block as procedural endpoint.Results:All patients converted to sinus rhythm during the operation.When followed up for 6months,9 patients maintained sinus rhythm with out antiarrhythmic drug.Post-operation atrial flutter presented in 1 patients.No other complication was observed.Conclusion:Contact force(CF)-sensing catheter have been proofed safety and effectiveness in the treatment of atrial fibrillation.
