SUBSTRATE MODIFICATION OF RIGHT ATRIUM IN A PATIENT WITH SCAR-RELATED ATRIAL FLUTTER
Mapping multiple atrial flutter re-entry circles after previous cryoballoon pulmonary vein isolations and multiple radiofrequency ablations can be challenging even for experienced specialists. Inappropriate radiofrequency ablation leads to scar-related electrical changes in the left and the right atria. We present a case of fractionated electrograms of the right atrium in a patient with previous radiofrequency ablations due to atrial fibrillation and atypical atrial flutter. PentaRay mapping catheter was used to identify the mechanisms of tachycardia precisely and to map fractionated electrograms. Key words: atypical atrial flutter, atrial fibrillation, right atrium substrate modification, catheter ablation, 3D mapping.
