Role of three-dimensional imaging integration in atrial fibrillation ablation

Figure 2 Postero-anterior view of the electroanatomic activation mapping of the left atrium and pulmonary veins. These have been reconstructed as five separate chambers using the Carto system and acquiring a few sites while the mapping catheter is manipulated in these anatomic structures. Colors indicate the activation sequence from the earliest in red (antero-medial part of the left atrium) to the latest in dark blue (postero-lateral part of the left atrium and distal part of the pulmonary veins). LA: Left atrium; LIPV: Left inferior pulmonary vein; LSPV: Left superior pulmonary vein; RIPV: Right inferior pulmonary vein; RSPV: Right superior pulmonary vein.
