addition, the HBA is applied to the bilateral upper posterior LA wall
and right carina region. CBA = cryoballoon ablation; HBA = hot balloon
ablation; LIPV = left inferior pulmonary vein; LSPV = left superior
pulmonary vein; RIPV = right inferior pulmonary vein; RSPV = right
superior pulmonary vein.
