Background—Conventional activation mapping in the dilated human left ventricle (LV) with
left bundle-branch block (LBBB) morphology is incomplete given the limited number of …

Background—The objective of this study was to assess the incidence and impact of
asymptomatic arrhythmia in patients with highly symptomatic atrial fibrillation (AF) who …

Objectives: This study investigated the impact on recurrences of 2 different substrate
approaches for the treatment of these arrhythmias. Background: Catheter ablation of …

Background—Electrical storm (ES) caused by recurrent episodes of ventricular tachycardia
(VT) can cause sudden death in patients with implantable cardioverter-defibrillators and …

Background: Catheter ablation reduces ventricular tachycardia (VT) recurrence and
implantable cardioverter defibrillator shocks in patients with VT and ischemic …

Over the past two decades cardiac cell therapy (CCT) has emerged as a promising new
strategy to cure heart diseases at high unmet need. Thousands of patients have entered …

Background: The deployment of an ablation line connecting the left inferior PV to the mitral
annulus (mitral isthmus line [MIL]) enhances the efficacy of pulmonary vein disconnection …

Objectives: We sought to analyze the time course of atrial fibrillation (AF) episodes before
and after circular plus linear left atrial ablation and the percentage of patients with complete …

Background—We investigated the impact of catheter ablation on ventricular tachycardia (VT)
recurrence and survival in a large number of patients with structural heart disease treated in …

Objectives: This study sought to examine whether suppressing premature ventricular
contractions (PVC) using radiofrequency ablation improves effectiveness of the cardiac …
