BackgroundThe cryoballoon (CB) has recently been used for performing pulmonary vein isolation (PVI) with concomitant left atrial posterior wall isolation (LAPWI). However, successful LAPWI using only the CB is technically challenging. This study aimed to evaluate the feasibility, safety, and efficacy of the cross-over technique, wherein an overlapped ablation is performed by placing the CB from both left and right directions in contact with the roof and bottom of the left atrium (LA).
