چکیده

Aims. To determine the role of prevalence low-voltage areas in occurrence arrhythmia recurrence after interventional treatment atrial fibrillation (AF). Methods. The study included 38 patients with paroxysmal (52.6%) and persistent (47.4%) forms AF who underwent using high-density electroanatomical mapping (at least 10,000 EGM points). Analysis maps was performed completion ablation procedure. area zones measured manually. Then, all regions activity were summed up; resulting value expressed as a percentage total surface left atrium (LA). Results. observation period 12.8±3.2 months. Based on results endocardial mapping, divided into 2 groups according to LA. first group an less than 5% atrium, second more atrium. had lower LA volume compared from group, mean values 119.87±16.35 ml 154.57±33.23 ml, respectively (p=0.007). In recorded one patient catheter treatment, 5 patients. Conclusion. Common detected by before procedure for AF, are predictor treatment.

High-density mapping of electrically induced atrial fibrillation in humans.

BACKGROUND Mapping studies in animals have suggested that atrial fibrillation (AF) is based on multiple reentering wavelets. Little information is available about the patterns of activation during AF in humans. The objective of the present study was to reconstruct and classify the patterns of human right atrial (RA) activation during electrically induced AF. METHODS AND RESULTS AF was induced...

Role of Echocardiography in Atrial Fibrillation Ablation.

Radiofrequency catheter ablation is an increasingly adopted strategy for difficult-to-manage patients with atrial fibrillation. Echocardiography is the key imaging modality to assess left atrialstructure and function. In this review, the role of echocardiography in atrial fibrillation ablationbefore, during and after ablation is discussed. Currently established roles of echocardiography inpatie...

The role of atrial remodeling for ablation of atrial fibrillation.

BACKGROUND Atrial fibrillation (AF) causes electrical, contractile, and structural remodeling of the atria. We investigated remodeling in patients undergoing AF ablation. METHODS Concomitant ablation of permanent AF, lasting 1 to 240 months, was performed in 73 patients (49.3% men) with a mean age of 66 +/- 9.1 years undergoing mitral valve operations. Electrical (AF cycle length from surface...
