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...

BACKGROUND: Epicardial radiofrequency catheter ablation is currently considered as the therapeutic option of choice in patients with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) and recurrent ventricular tachycardia (VT). We hypothesised that inducibility of VT may guide the ablation strategy and thereby affect long-term results. Additional epicardial ablation was only performed if VT were still inducible after thorough endocardial ablation. METHODS: The objective was to examine an inducibility-guided ablation approach by comparing the long-term results between endocardial and epi-endocardial radiofrequency catheter ablation of VT in a large cohort of patients with ARVD/C...

BACKGROUND: Paroxysmal atrial tachyarrhythmias frequently occur in beta-thalassemia major (β-TM) patients. The aim of the current study was to evaluate the atrial electromechanical delay (AEMD) in a large β-TM population with normal cardiac function and its relationship to atrial fibrillation (AF) onset. METHODS: Eighty β-TM patients (44 men, 36 women), with a mean age of 36.2 ± 11.1 years, and 80 healthy subjects used as controls, matched for age and gender, were studied for the occurrence of AF during a 5-year follow-up, through 30-day external loop recorder (ELR) monitoring performed every 6 months...

PURPOSE: Catheter radiofrequency ablation (RFA) is an effective treatment for symptomatic paroxysmal atrial fibrillation (AF). It has been demonstrated that the multielectrode pulmonary vein ablation catheter (PVAC) has favourable outcomes at 6-12 months post-ablation, but there are only few studies with a long-term follow-up. METHODS: We retrospectively reviewed 77 consecutive PVAC procedures in our centre, from November 2007 to December 2012. RFA was attempted in patients with symptomatic paroxysmal AF (mean age 58...

PURPOSE: Cardiac resynchronization therapy (CRT) is an established therapeutic option in selected heart failure patients (pts). However, the transvenous left ventricular (LV) lead implantation remains ineffectual in a considerable number of pts. Transapical LV (TALV) lead implantation is an alternative minimally invasive, surgical, endocardial implantation technique. The aim of the present prospective study is to determine the long-term outcome, including the cerebral thromboembolic complications, of pts who underwent TALV lead placement...

PURPOSE: Radiofrequency catheter ablation of typical atrial flutter can vary largely in duration from patient to patient. The purpose of this work was to determine optimal combination of ablation settings leading to the highest procedural efficacy. METHODS: Our retrospective multivariate analysis comprised 448 patients undergoing atrial flutter ablation with nonirrigated 8-mm catheters at 19 clinical centers. Four procedural variables were included in the prognostic model: preset maximum temperature, preset maximum power, catheter-tip material (gold vs...

PURPOSE: Achieving complete mitral isthmus (MI) conduction block for atrial fibrillation (AF) ablation remains challenging. We hypothesized that transseptal puncture (TSP) at the anteroinferior aspect of the atrial septum (anteroinferior TSP) could shorten the distance to the MI and improve catheter contact and stability, enabling complete MI block. This study investigated the efficacy of anteroinferior TSP for MI ablation in AF patients. METHODS: Three hundred and twenty consecutive patients (mean age: 62 ± 9 years, 84 % male) with persistent AF undergoing AF ablation, including MI ablation, were enrolled...
