To explore the efficacy and safety of short term outcome of catheter ablation for symptomatic PACs.
Symptomatic PACs patients without organic heart diseases were enrolled. All of them were underwent electrophysiologic study for PACs and ablation using three-dimensional mapping technology.
There were 9 patients (4 male) with symptomatic PACs included in this study, and the average age was 44.1±17.2 years. The average PACs were 19148.0±5437.8/24h (9860-28100), the paired PACs were 180.9±208.8 (0-660) and the paroxysmal atrial tachycardia (AT) was 87.2±92.6 (0-239) with total account of 419.9±386.8 (0-1042). The common site distribution for PACs was ostium of the coronary sinus, crista terminalis, annulus, and appendage. All the patients were successfully ablation, and the average PACs were decreased to 39.3±46.1/24h (0-134). During a median of 9 months follow up, there were no symptomatic PACs recurred.
Focal PACs commonly originates from ostium of coronary sinus, crystal terminalis, annulus and appendage. The radiofrequency catheter ablation yields a satisfying success rate and very low complication rate and could be the first line choice for treating focal PACs in experienced electrophysiological center.
