FIGURE 1

Three dimensional electroanatomical map of left atrium in posteroanterior view visualized by CARTO3 system. (A) Using visualizable steerable sheath (red dashed line), it is easier to understand spatial relationship between the ablation catheter (yellow asterisk) and the sheath. (B) Using standard steerable sheath, only the ablation catheter is visualized by the CARTO3 system. LIPV, left inferior pulmonary vein; LSPV, left superior pulmonary vein; RIPV, right inferior pulmonary vein; RSPV, right superior pulmonary vein.
