Arrhythmic Events in Brugada Syndrome: A Nationwide Israeli Survey of the Clinical Characteristics, Treatment; and Long-Term Follow-up (ISRABRU-VF).

Background: Limited information exists about detailed clinical characteristics and management of the small subset of Brugada syndrome (BrS) patients who had an arrhythmic event (AE).

Objectives: To conduct the first nationwide survey focused on BrS patients with documented AE.

Methods: Israeli electrophysiology units participated if they had treated BrS patients who had cardiac arrest (CA) (lethal/aborted; group 1) or experienced appropriate therapy for tachyarrhythmias after prophylactic implantable cardioverter defibrillator (ICD) implantation (group 2).

Importance of ventricular tachycardia storms not terminated by implantable cardioverter defibrillators shocks in patients with CASQ2 associated catecholaminergic polymorphic ventricular tachycardia.

In this study, the clinical and implantable cardioverter-defibrillator (ICD)-related follow-up of patients with catecholaminergic polymorphic ventricular tachycardia (CPVT) with homogenous missense mutations in CASQ2 was summarized. Patients were followed in a pediatric cardiology clinic and an ICD clinic. All patients were treated with high-dose β blockers.

Clinical and electrophysiologic outcomes of patients undergoing percutaneous endocardial ablation of scar-related ventricular tachycardia: a single-center experience.

Background: For patients with ventricular tachyarrhythmias, implantable cardioverter defibrillators are a mainstay of therapy to prevent sudden death. However, ICD shocks are painful, can result in clinical depression, and do not offer complete protection against death from arrhythmia. Radiofrequency catheter ablation of ventricular tachycardia in the setting of ischemic cardiomyopathy has emerged recently as a useful adjunctive therapy to ICD.
