Abstract:
Objective To summarize radiofrequency cather ablation (RFCA)of tachycardias with right sid-ed accessory atrioventricular pathway in 7 patients with persistent left superior vena cava (PLSVC). Methods RF-CA for right sided accessory atrioventricular pathway in 7 patients with PLSVC was carried out . Coronary sinus ac-cess was performed through the left subclavian and the left femoral vein respectively. Swartz sheath was used during ablation if neccesary. Results There was no siginificant differences in fluoroscopy time between the left subclavian approach and the left femoral vein approach[(2.8 ± 0.6)min vs (3.2 ± 0.3)min, P>0.05)]. No recurrence of ac-cessory pathway conduction was found during a mean follow-up of (23 ± 11) months. The mean discharging time and fluoroscopy time were (312 ± 67)s and (17 ± 5)min respectively. Conclusions Although RFCA of right sided accessory atrioventricular pathway in patients with PLSVC shows specialities in cather manipulation , mapping and ablation, high successful results can be achieved by experienced physician.
