BACKGROUND: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with advanced heart failure. Nearly 30% of candidates are inadequate responders. Proper patient selection, left ventricle (LV) lead placement optimization, and optimization of the programming of the CRT device are important approaches to improve outcome of CRT. We examined the role of three-dimensional (3D) echocardiography in determining the optimal LV lead position as a method of optimizing CRT response...

BACKGROUND: The postural tachycardia syndrome (POTS) is a heterogeneous group of disorders that results in symptoms of orthostatic intolerance. Excess blood pooling has been observed to cause low effective circulating volume in the central vasculature. Consequently, acute volume loading with IV saline has emerged as a potential strategy for clinical intervention. We evaluated the impact of acute volume loading on both the signs and symptoms of patients suffering from POTS. METHODS: Fifty-seven subjects screened from our population of POTS patients and assenting to participation were administered the two surveys by telephone...

BACKGROUND: A significant minority of cardiac transplant patients require permanent pacemaker (PPM) implant, primarily for sinus node dysfunction. The stability of pacing indices has not been determined in this unique patient population, and data regarding ongoing need for pacing are limited. METHODS: Pacing indices (sensing, threshold, and impedance) as well as the percentage of time patients required pacing were recorded, from 30 cardiac transplant patients that underwent PPM implant, over 1 year of follow-up...

PURPOSE: Bedside vascular ultrasound machines are increasingly available. They are used to facilitate safer vascular access across a number of different specialties. In the electrophysiology laboratory however, where patients are frequently anticoagulated and require the insertion of multiple venous sheaths, anatomical landmark techniques predominate. Despite the high number of vascular complications associated with electrophysiological procedures and the increasing evidence to support its use in electrophysiology, ultrasound remains underutilised...

PURPOSE: In patients who undergo implantable cardiac defibrillator (ICD) implantation for primary prevention of sudden cardiac death (SCD), data is unclear whether their ICD generator needs to be replaced at end of life if their left ventricular ejection fraction (EF) improves. Despite improvement in EF, the underlying scar may represent a potential substrate for ventricular arrhythmias. METHODS: Data on 280 patients who underwent ICD implantation for primary prevention of SCD was obtained from two centers...

PURPOSE: Hibernating myocardium (HM) is associated with sudden cardiac death (SCD). Little is known about the electrophysiological properties of HM and the basis of its association with SCD. We aimed to electrophysiologically characterize HM in patients with ventricular tachycardia (VT). METHODS: Endocardial voltage mapping, metabolic (18)FDG-positron emission tomography (PET) and perfusion (82)Rb, (201)Tl, or (99m)Tc scans were performed in 61 ischemic heart disease patients with VT...

PURPOSE: The use of oral anticoagulation (OAC) in the elderly population with atrial fibrillation (AF) treated in long-term care (LTC) facilities is inconsistent. We examined the magnitude and sources of the gap between indicated and prescribed OAC in the elderly population with AF. METHODS: We retrospectively scanned the electronic medical record (EMR) and pharmacy data of 25 LTC facilities in Ontario, Canada. The diagnosis of AF was drawn from EMR. Different attributable risk factors for possible failure to prescribe OAC were examined...

PURPOSE: The atrial transseptal procedure is used in catheter ablation of left-sided arrhythmias. Studies in adult patients have shown the SafeSept™ transseptal guidewire (SSTG) to be effective in atrial transseptal procedures. We analyzed our 5-year experience with SSTG use in pediatric and congenital heart disease patients undergoing catheter ablation. METHODS: This is a single-center retrospective analysis of patients undergoing catheter ablation from 2009 to 2014...

BACKGROUND: New oral anticoagulants (NOACs) have been shown to be comparable to warfarin in patients with non-valvular atrial fibrillation (AF). This meta-analysis was performed to evaluate the efficacy and safety of NOACs for perioperative anticoagulation of AF catheter ablation. METHODS: PubMed, Embase, the Cochrane Library, CNKI, VIP, and SinoMed were searched for articles published up to August 30, 2015. The data were calculated with RevMan 5.2 using a fixed-effects model...

BACKGROUND: Atrial fibrillation (AF) and cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL) are two separate entities that coexist in a significant percentage of patients. We sought to investigate whether AF inducibility during CTI AFL ablation predicted the occurrence of AF at follow-up after successful AFL ablation. METHODS: A systemic review of Medline, Cochrane, and Embase was done for all the clinical studies in which assessment of AF inducibility in patients undergoing ablation for CTI AFL was performed...

PURPOSE: Patients with ischemic cardiomyopathy (ICM) are prone to scar-related ventricular tachycardia (VT). The success of VT ablation depends on accurate arrhythmogenic substrate localization, followed by optimal delivery of energy provided by constant electrode-tissue contact. Current manual and remote magnetic navigation (RMN)-guided ablation strategies aim to identify a reentry circuit and to target a critical isthmus through activation and entrainment mapping during ongoing tachycardia...

PURPOSE: The present systematic review and meta-analysis aimed to assess and compare the safety and efficacy of radiofrequency (RF) and cryoballoon (CB) ablation for paroxysmal atrial fibrillation (PAF). RF and CB ablation are two frequently used methods for pulmonary vein isolation in PAF, but which is a better choice for PAF remains uncertain. METHODS: A systematic review was conducted in Medline, PubMed, Embase, and Cochrane Library. All trials comparing RF and CB ablation were screened and included if the inclusion criteria were met...

PURPOSE: The purpose of this study was to evaluate electrophysiologic study (EPS) in risk stratification of relative indications for pacemaker implantation (PMI) after transcatheter aortic valve implantation (TAVI). METHODS: We reviewed files of all patients who had a left bundle branch block (LBBB) and underwent EPS after TAVI between 3/2009 and 5/2015. The indications for EPS were new-onset LBBB and the presence of an old or a new-onset LBBB associated with either PR prolongation after TAVI (∆PR >20 ms) or with "slow" atrial fibrillation (<100/min)...

PURPOSE: Multiple studies have shown the efficacy and potentially curative effect of catheter ablation (CA). However, CA is always accompanied by a considerable recurrence rate for atrial fibrillation (AF). We hypothesized that pre-procedure assessments of baseline left atrial appendage emptying flow velocity (LAAFV) and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels would help identify abnormal atrial substrate and offer preliminary evidence regarding susceptibility to AF recurrence in patients with paroxysmal or persistent AF, respectively...

PURPOSE: Catheter ablation of the slow pathway is the most effective treatment for atrioventricular nodal reentrant tachycardia (AVNRT). Cryoenergy, compared to radiofrequency, relates to lower heart block risk but higher incidence of AVNRT recurrences. The aims of this study are to confirm the safety and efficacy of AVNRT cryoablation and to identify predictors of long-term recurrences. METHODS: Among 241 patients undergoing AVNRT cryoablation, 239 (99.2%) experienced acute effective cryoablation of the slow pathway, and no procedure-related complications were reported...

PURPOSE: Risk stratification of serious arrhythmic events in patients with nonischemic heart failure (HF), beyond estimates of left ventricular ejection fraction (LVEF), remains an important clinical challenge. This study aims to determine the clinical value of different noninvasive and invasive tests as predictors of serious arrhythmic events in patients with nonischemic HF. METHODS: A prospective observational study was conducted including 106 nonischemic HF patients who underwent a comprehensive clinical and laboratory evaluation including two-dimensional echocardiography, 24-h Holter monitoring, cardiopulmonary exercise testing (CPX), and an invasive electrophysiological study...

INTRODUCTION: Epicardial access (EpiAcc) has become an important adjunct for ventricular tachycardia (VT) or premature ventricular complex (PVC) ablation. We hypothesized that post-procedural pericarditis may lead to an increased risk of atrial fibrillation (AF), and therefore assessed the incidence and clinical impact of post-procedural AF in patients undergoing EpiAcc. METHODS: We reviewed the records of all patients who underwent EpiAcc as part of an ablation procedure between January 1, 2004 and July 31, 2014 at Mayo Clinic Rochester...

PURPOSE: Data on uninterrupted rivaroxaban taken preoperatively for radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) is limited. The aim was to evaluate safety and efficacy of rivaroxaban taken in the morning for AF ablation, especially with regard to asymptomatic cerebral emboli (ACE) and anticoagulation parameters. METHODS: We prospectively evaluated 147 consecutive patients who underwent RFCA (mean age 66, 110 patients with paroxysmal AF), 76 of whom were on rivaroxaban, 71 on warfarin...
