Letter by May et al Regarding Article, “Use of Dabigatran for Periprocedural Anticoagulation in Patients Undergoing Catheter Ablation for Atrial Fibrillation” by Bassiouny et al. To the Editor: In patients undergoing catheter ablation for atrial fibrillation with pulmonary vein isolation, the recent study by Bassiouny et al found no evidence to suggest a higher risk of thromboembolic or hemorrh...

Letter by Hong et al regarding article, "Cardiac sodium channel (SCN5A) variants associated with atrial fibrillation".

BACKGROUND Genetic studies have identified ion channel gene variants in families segregating atrial fibrillation (AF), the most common arrhythmia in clinical practice. Here, we tested the hypothesis that vulnerability to AF is associated with variation in SCN5A, the gene encoding the cardiac sodium channel. METHODS AND RESULTS We resequenced the entire SCN5A coding region in 375 subjects with...

Letter by Bartoletti et al Regarding Article, "Ablation of Persistent Atrial Fibrillation Targeting Low-Voltage Areas With Selective Activation Characteristics".

BACKGROUND Complex-fractionated atrial electrograms and atrial fibrosis are associated with maintenance of persistent atrial fibrillation (AF). We hypothesized that pulmonary vein isolation (PVI) plus ablation of selective atrial low-voltage sites may be more successful than PVI only. METHODS AND RESULTS A total of 85 consecutive patients with persistent AF underwent high-density atrial volta...
