Figure 1. Left atrial (LA) distribution of low voltage areas (LVA) and examples of voltage maps of patients without LVA (A ), with disseminated pattern of voltage-defined remodelling as 3 out of 5 LA segments were affected (B ) and severe LVA burden >20% of the total LA surface area (C ). All panels show anteroposterior and posteroanterior views of CARTO®3 LA shells acquired following pulmonary veins isolation and restoration of sinus rhythm with cardioversion. Color-coding is defined as follows: <0.5 mV=diseased atrial tissue (red), >0.5 mV=healthy atrial myocardium (pink). ant=anterior wall, sep=septum, post=posterior wall, inf=inferior wall, lat=lateral wall, 1=left atrial appendage, 2=right upper pulmonary vein, 3= right lower pulmonary vein, 4=left upper pulmonary vein, 5=left lower pulmonary vein
