[Radiofrequency ablation of accessory atrioventricular pathways. Predictive factors of acute result and outcome]

ABSTRACT

The purpose of this study was to evaluate safety and efficacy of catheter ablation of accessory pathways [APs] and to identify predictive factors of acute result and outcome. The patient population included 173 patients who had undergone ablation of an AP. The success rate was 91,6%, a major complication occurred in 4 patients [2.3%] and 8 patients [4.9%] developed a recurrence after a successful ablation procedure. Only one factor predicted success [sex], tow variables predicted development of a major complication [septal AP, age < 16 years], and three factors predicted arrhythmia recurrence [mid septal, right free wall, and multiple APs]
