Why the study?
Mapping multiple atrial tachycardias after prior cryoballoon pulmonary vein isolations and radiofrequency ablations is challenging, and high-density mapping with the HD Grid catheter may help identify macro-reentry mechanisms and avoid unnecessary ablation.

May aid precise mapping of complex post-ablation atrial tachycardias and reduce unnecessary ablation; hypothesis-generating and requires confirmation in larger studies.
The HD Grid high-density mapping catheter can effectively visualize mechanisms and guide successful ablation in complex atypical atrial flutter.
