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
