Abstract:
New atrial flutter (AFL) that arises after pulmonary vein isolation (PVI) by catheter or surgical ablation can originate from reconnection of a pulmonary vein (PV). Reisolation of PVs with cryoballoon ablation (CBA) for treatment of peri-PV AFL after Maze or PVI has not previously been reported. The present case series describes use of CBA to treat post-PVI and post-Maze PV-dependent AFL. In these cases, CBA was used to reisolate the PVs and terminate AFL without requiring additional lesion sets for treatment of AFL.
