ABSTRACT

Objective To evaluate the safety and clinical effects of radiofrequency single catheter ablation (RESCA)for right ventrieular arrhythmia(RVA).Method A total of 111 patients data in the Second Affiliated Hospital of Wenzhou Medical College from May 2003 to May 2008,were retrospectively analyzed aged(45.2±16.7)years old including 41 men and 70 women,consisted of 13 patients of ventricular tachycardia(VT)and 98 patients of premature ventricular contractions(PVC).There were 104 casess from right ventricular outflow tract arrhythmia(RVOTA)and 7 cases from right ventricular inflow tract arrhythmia(RVITA).According to use single catheter approach or common technique,electrophysiolo-gical study,pacing and/or activation mapping and Catheter ablation were performed,were separated into two groups.①Single catheter group:27 men and 49 women,ages(44.5±16.9)years old;consisted of 62 patients of RVOT-PVC,9 patients of RVOT-VT and 5 patients of RVIT-PVC.②Control group:14 men and 21 women,ages(46.7±16.5)years old;consisted of 29 patients of RVOR-PVC,4 patients of RVOT-VT and 2 patients of RVIT-PVC.Results Operations in two groups came off smoothly and no ablation related complications in two groups.Procedure time and fluoroscopy time[(55.23±26.24)min and(9.93±5.32)min]in single catheter group were significantly shorter than those in control group [(68.37±21.83)min and(12.96±4.54)min,t=2.76 and 3.09,all P<0.01].Cost in the fromer (12440.32±761.24)RMB were significantly less than those in the latter[(22119.51±1071.07)RMB,t=46.09,P<0.01].Ablated successful rate in the near future,at a specified future date and other parameter were similar in two groups.Conclusions Right ventricular arrhythmia can be ablated with single catheter approach in safety,efficacious,easy to operate and lower cost.
