Why the study?
Reisolation of pulmonary veins with cryoballoon ablation for the treatment of peri-pulmonary vein atrial flutter after Maze or pulmonary vein isolation has not previously been reported.
Does cryoballoon ablation terminate PV-dependent atrial flutter after previous PVI or Maze procedure?
Does cryoballoon ablation terminate PV-dependent atrial flutter after previous PVI or Maze procedure?
Cryoballoon ablation is a feasible approach to reisolate pulmonary veins and terminate PV-dependent atrial flutter following previous PVI or Maze procedures.

May support CBA reisolation for PV-dependent post-ablation AFL; hypothesis-generating pending comparative trials.
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.
