How to unmask septal local abnormal ventricular activities with the new LUMIPOINT^TM software

We report the use of the new automated tool Lumipoint^TM for the detection of LAVA (local abnormal ventricular activities) when they are buried within the far-field ventricular signal, especially in regions of preserved myocardial thickness, such as the left ventricular (LV) septum. The LV substrate and the tachycardia circuit during ventricular tachycardias of a 60-year-old man with dilated cardiomyopathy were mapped using an ultra-high-density mapping system and then the Lumipoint^TM, analyzing the EGMs of interest, identified the LAVA in the inferoseptal region. This algorithm may be helpful to quickly target the septal substrate avoiding misleading interpretation.
