Abstract

Cardiac Electrophysiologic Study under Electro-anatomical mapping and Radio-frequency ablation (RFA) is currently for treat cardiac arrhythmias. The study aimed to assess the benefit and safety of treatment for idiopathic ventricular outflow tract,either premature ventricular complex (PVC) or ventricular (VT). A retrospective study of 59 patients at the Central Chest Institute of Thailand between 1 January 2017 and 31 October 2018 with the follow-up period more than six months conducted. The average age of patients was 47.53 years old, female 78% and male 22%. The most common site of origin PVC or VT was at the right ventricular outflow tract, which detected up to 93.3% by 12-leads electrocardiogram criteria to 89.9% by electro-anatomical method. The success rate of radiofrequency ablation was 81.4%, unsuccessful cases depend on the site of origin of rate 18.6% comparable with the previous study.The cause of unsuccess rate depended on the site of origin PVC or VT. The complication rate was 5.1%, cardiac tamponade 3.4% and bleeding of puncture site 1.7% respectively. The recurrence rate at 1 year was 8.5%. In conclusion, the Cardiac Electrophysiologic study under Electro-anatomical mapping for treatment of outflow tract VT and PVC were safe, effectively and low recurrence rate at 1 year.
