Abstract:
Objective To explore the feasibility and methodology of radiofrequency catheter ablation (RFCA) guided by 3D navigation system (Ensite-NavX) for right atrioventricular accessory pathway.Method Thirty-three cases of right accessory pathway atrioventricular reentrant tachycardia including 16 cases in right free wall,3 in right middle septum,14 in right posterior septum; 23 cases of dominant accessory pathway and 10 cases of concealed were treated by RFCA guided by NavX navigation.NavX navigation modeling method or spatial localization method was exploited to locate target positioning.Result All patients were successfully ablated without serious complications.Among them,25 cases were operated without exposure to X-ray,7 patients were exposed for several seconds to verify catheter position,1 case in right free wall was ablated under X-ray combined with Swartz sheath ablation.Conclusion Nonfluoroscopy or less fluoroscopy RFCA for right atrioventricular accessory pathway with Ensite-NavX is safe and feasible,modeling or spatial orientation method are helpful to locate the ablation target positioning.
