Second-generation cryoballoon (CB2)-based pulmonary vein isolation (PVI) has demonstrated encouraging clinical results for the treatment of paroxysmal atrial fibrillation (AF) and persistent AF. However, rhythm follow-up after PVI is mainly based on Holter electrocardiography of limited duration. ⋯ CB2-PVI seems safe and feasible in patients with an implanted cardiac device. A significantly higher AF/AT burden was seen in patients with an implanted cardiac device compared to a control group.

Multicenter Study
Rate control and clinical outcomes in patients with atrial fibrillation and obstructive lung disease.
Rate-control medications are considered first-line treatment for patients with atrial fibrillation (AF). However, obstructive lung disease (OLD), a condition prevalent in those with AF, often makes it difficult to use those medications because of the lack of studies on new-onset AF in patients with OLD. ⋯ Among patients with AF-OLD, rate-control treatment using selective and nonselective BB was associated with a significant reduction in mortality compared with CCB use. Further prospective randomized trials are required to confirm these findings.
