Case ReportsPercutaneous stellate ganglion block suppressing VT and VF in a patient refractory to VT ablation.
Electrical storm is a condition characterized by multiple episodes of ventricular tachycardia (VT) or ventricular fibrillation (VF) in a short period of time. ⋯ This case illustrates the potential of ongoing, temporary percutaneous stellate ganglion blockade in suppressing ventricular arrhythmogenesis.

Comparative StudyDabigatran versus warfarin therapy for uninterrupted oral anticoagulation during atrial fibrillation ablation.
Uninterrupted oral anticoagulant (OA) therapy with warfarin has become the standard of care at many centers performing catheter ablation of atrial fibrillation (AF). Compared with warfarin, dabigatran, a direct thrombin inhibitor, has been demonstrated to reduce the risk of stroke in nonvalvular AF with similar bleeding risk. Few data exist on the safety profile of uninterrupted dabigatran therapy during AF ablation. ⋯ The administration of dabigatran is as safe and effective as warfarin for uninterrupted OA therapy during catheter ablation of AF.

Case ReportsPotential new indication for ivabradine: treatment of a patient with congenital junctional ectopic tachycardia.
Ivabradine is a new antiarrhythmic agent with direct inhibition of the pacemaker (If) current. It has been used extensively to decrease sinus rate in the treatment of cardiac failure, and also in a single case of atrial ectopic tachycardia in a child. Here we report the case of a 3-year-old girl with congenital junctional ectopic tachycardia (JET), resistant to conventional antiarrhythmic medications, who was successfully treated with ivabradine. We suggest that ivabradine can be an effective treatment for junctional automatic tachycardias and can be considered as a new line of therapy for this incessant form of tachycardia.
