Left atrium voltage assessment is essential in planning an atrial fibrillation catheter ablation. One of the key tools to validate the scar density is the electroanatomic reconstruction by the ultra-high definition mapping system.

The voltage map can define the scar density, setting the values according to predefined parameters. A 78-year-old male, with history of hypertension and diabetes mellitus type II, with paroxysmal atrial fibrillation and P wave progressive decreasing voltage in sinus rhythm (Figure 1A), underwent a pulmonary vein isolation procedure.
