PURPOSE: Late adverse myocardial remodeling after acute myocardial infarction (AMI) is strongly associated with sudden cardiac death (SCD). Cardiac magnetic resonance (CMR) performed early after AMI can predict late remodeling and SCD risk with moderate accuracy. This study assessed the ability of CMR-measured circumferential strain (CS) to add incremental predictive information to late gadolinium enhancement (LGE). METHODS: Patients with an AMI and LVEF < 50% were screened for inclusion...

PURPOSE: Guidelines recommend that radiation exposure during AF catheter ablation procedures should be 'as low as reasonably achievable' (ALARA), particularly since many patients may have multiple procedures. Consequently, avoiding radiation exposure altogether must, if safe to do so, be the ultimate goal. The primary objective was to determine the feasibility and efficacy of fluoroscopy-free AF ablation compared to the fluoroscopy-assisted procedure. METHODS: Patients underwent AF ablation using commercially available technology with no routine pre-procedural imaging...

PURPOSE: Paroxysmal supraventricular tachycardia (PSVT) ablation can result in injury to the atrioventricular (AV) node causing complete heart block requiring permanent pacemaker (PPM) implantation. Few studies have examined the impact of hospital PSVT ablation volume and PPM implantation rates post ablation. METHODS: We included adult patients from the Nationwide Inpatient Sample (NIS) database, from 1998 to 2011, using ICD-9 diagnoses codes 427.0 and 427.89 for PSVT and ICD-9 procedure code 37...

PURPOSE: Epicardial pulmonary vein isolation has become an increasingly used therapy for medically resistant atrial fibrillation. The purpose of the present study was therefore to evaluate if epicardial pulmonary vein isolation combined with ganglionated plexi ablation affects the size and mechanical function of the left atrium, and whether the effects are dependent on the extensiveness of the ablation applications. METHODS: A total of 42 patients underwent an echocardiographic examination prior to and 6 months after a minimal invasive epicardial pulmonary vein isolation procedure for the assessment of the effects on left atrial size and function...

INTRODUCTION: The effects of device and patient characteristics on health and economic outcomes in patients with cardiac implantable electronic devices (CIEDs) are unclear. Modeling can estimate costs and outcomes for patients with CIEDs under a variety of scenarios, varying battery longevity, comorbidities, and care settings. The objective of this analysis was to compare changes in patient outcomes and payer costs attributable to increases in battery life of implantable cardiac defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-D)...

PURPOSE: Adjunctive ganglionated plexi (GP) ablation may improve success rates for treatment of atrial fibrillation (AF) when combined with pulmonary vein (PV) isolation. Existing meta-analyses on GP ablation have included observational studies and have not incorporated more recent randomized clinical trial data. Moreover, the impact of AF subtype (paroxysmal vs. persistent) on outcomes of GP ablation has not been well established. METHODS: We performed a meta-analysis of randomized controlled trials (RCTs) comparing GP ablation + pulmonary vein (PV) isolation versus PV isolation alone according to the subtype of AF...

PURPOSE: Left atrial arrhythmia substrate assessment can involve multiple imaging and electrical modalities, but visual analysis of data on 3D surfaces is time-consuming and suffers from limited reproducibility. Unfold maps (e.g., the left ventricular bull's eye plot) allow 2D visualization, facilitate multimodal data representation, and provide a common reference space for inter-subject comparison. The aim of this work is to develop a method for automatic representation of multimodal information on a left atrial standardized unfold map (LA-SUM)...
