Randomized Controlled Trial
Pulmonary vein triggers play an important role in the initiation of atrial flutter: Initial results from the prospective randomized Atrial Fibrillation Ablation in Atrial Flutter (Triple A) trial.
The incidence of atrial fibrillation (AF) after ablation of a cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL) is high. ⋯ Pulmonary vein triggers play an important role in AFL. PVI can prevent the recurrence of AFL, even without CTI ablation.

Randomized Controlled Trial Multicenter Study
MRI scanning in patients with new and existing CapSureFix Novus 5076 pacemaker leads: randomized trial results.
Magnetic resonance imaging (MRI) can be safely performed in patients with magnetic resonance (MR)-conditional pacemaker systems but remains relatively contraindicated with non-MR-conditional pacemaker systems. ⋯ MRI scans can be performed safely without positioning restrictions in patients with Medtronic CapSureFix Novus 5076 leads connected to an MR-conditional pacemaker.

Randomized Controlled Trial Multicenter Study
Digoxin in patients with permanent atrial fibrillation: data from the RACE II study.
The Atrial Fibrillation Follow-up Investigation of Rhythm Management trial showed that digoxin was associated with increased mortality in patients with atrial fibrillation. ⋯ The use of digoxin was not associated with increased morbidity and mortality.

Randomized Controlled Trial
Impact of biatrial defragmentation in patients with paroxysmal atrial fibrillation: results from a randomized prospective study.
Single procedure success rates of pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (PAF) are still unsatisfactory. In patients with persistent atrial fibrillation (AF), ablation of complex fractionated atrial electrograms (CFAEs) after PVI results in improved outcomes. ⋯ Patients with sustained AF after PVI in a PAF cohort are rare. Regarding AF/AT recurrence, these patients did not benefit from further CFAE ablation compared to PVI alone, but are exposed to longer procedure duration, fluoroscopy time, and radiofrequency application time.

Randomized Controlled Trial
A prospective randomized controlled trial on the incidence and predictors of late-phase postoperative atrial fibrillation up to 30 days and the preventive value of biatrial pacing.
Postoperative atrial fibrillation (POAF) is considered to be a transient arrhythmia in the first week after cardiac surgery. ⋯ POAF is not limited to the first week after cardiac surgery but also occurs frequently in the postoperative month. It is desirable to regularly follow patients with POAF for atrial fibrillation recurrences after discharge.
