How to unmask septal local abnormal ventricular activities with the new LUMIPOINTTM software.

We report the use of the new automated tool LumipointTM 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 LumipointTM, 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.
