Occurrence of symptoms after catheter ablation of atrial fibrillation



Occurrence of symptoms after catheter ablation of atrial fibrillation



Bratislavske Lekarske Listy 116(8): 461-464



The aim of our study was to verify the efficiency of catheter ablation of atrial fibrillation (CA AF) according to the "atrial fibrillation (AF) burden"(time spent in AF) and symptoms related to AF. We retrospectively analysed a selected set of 133 patients with atrial fibrillation (81% men, 19% women) who underwent an invasive therapy in the form of CA AF and at the same time had an implanted long-term ECG loop recorder (Reveal XT) in a period of eight years. We investigated AF burden and objective symptoms of AF by data obtained from a long-term implantable ECG loop recorder. Subjective symptoms related to AF were identified during outpatient controls. Firstly, our results demonstrate for the first time a clinically relevant increase in the occurrence of asymptomatic episodes of AF after CA AF. Secondly, when analysing AF symptoms and AF burden at the same time, CA AF in terms of reduction of symptoms and shortening the time in AF had a better effect in patients undergoing 1 procedure (CA AF) compared to patients undergoing repeated procedures (re CA AF). The increase in the occurrence of asymptomatic episodes of AF is of considerable importance both for the clinical evaluation of ablation efficacy and for individualized clinical management of patients, especially with respect to antithrombotic therapy (Fig. 10, Ref. 19).
