Abstract:
OBJECTIVEThe aim of this trial is to compare the efficacy and safety between national-made and imported ablation catheters for the treatment of atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT).
METHODA total of 1342 patients with AVNRT or AVRT were randomly treated with national-made ablation catheter (Group 1, n = 672) or imported ablation catheter (Group 2, n = 670).
RESULTSThe immediate ablation success rate was similar in Group 1 and Group 2 (97.9% vs. 99.1%, P > 0.05). There were also no significant differences in the procedure time [(68 +/- 36) min vs. (67 +/- 34) min], the fluoroscopic time [(14 +/- 14) min vs. (10 +/- 11) min], the number of energy delivery [(4.5 +/- 4.5) beats vs. (4.6 +/- 3.9) beats], the ablation time [(260 +/- 218) s vs. (257 +/- 207) s] and the score of ablation catheter performance evaluation [(4.4 +/- 0.5) vs. (4.5 +/- 0.4) ] between the two groups (all P > 0.05). Three patients developed pericardial effusion (1 in Group 1 and 2 in Group 2, P > 0.05). Incidence of recurrence of tachycardia during the 3 months follow up was similar between the 2 groups (14 in Group1 vs. 16 in Group 2, P > 0.05).
CONCLUSIONNational-made and imported radiofrequency ablation catheters have similar efficacy and safety for treatment of AVNRT and AVRT.
