PURPOSE: Pulmonary vein isolation is now widely accepted for the treatment of symptomatic atrial fibrillation refractory to antiarrhythmic drugs. However, multiple procedures are often required to significantly reduce atrial fibrillation (AF) recurrence. In the present study, we analyzed the acute results and the midterm clinical outcome of a second-generation cryoballoon ablation (CB-A) performed during repeat procedures for recurrence of AF after an initial procedure performed with conventional radiofrequency (RF)...

PURPOSE: Lead dislocations of pacemaker systems are reported in all and even in high-volume centers. Repeated procedures necessitated by lead dislocations are associated with an increased risk of complications. We investigated a minimal invasive method for right atrial and ventricular lead repositioning. METHODS: The minimal invasive method was applied only when passive fixation leads were implanted. During the minimal invasive procedure, a steerable catheter was advanced through the femoral vein to move the distal end of the lead to the appropriate position...

BACKGROUND: Adenosine administration after initial pulmonary vein isolation (PVI) reveals dormant conduction and predicts atrial fibrillation (AF) recurrence. Elimination of dormant conduction when present may increase a long-term success rate of AF ablation procedures. There are no studies till date using adenosine to reveal acute reconduction of pulmonary veins (PVs) after epicardial PVI during a hybrid AF ablation procedure. METHODS: We included 24 patients (21 male, 55 ± 9 years) undergoing hybrid ablation for symptomatic paroxysmal (n = 12) and persistent (n = 12) AF, using an epicardial bipolar radiofrequency clamp to perform PVI...

PURPOSE: Catheter ablation for atrial fibrillation is performed with and without deep sedation, which could affect the arrhythmogenic activity during the procedure. We investigated the impact of sedation on electrophysiological properties in patients with AF who underwent catheter ablation. METHODS: This study consisted of 255 consecutive patients with atrial fibrillation (229 males, persistent: 105 patients) who underwent a single-catheter ablation procedure. The patients were divided into the following two groups according to the depth of sedation during the procedure: group M (mild sedation with flunitrazepam in 138 patients) and group D (deep sedation with propofol in 117 patients)...

BACKGROUND: The second-generation cryoballoon (cryoballoon Advance; CB-A) offers excellent outcomes on the mid-term follow-up. To the best of our knowledge, little is known regarding the long-term outcome after CB-A ablation for paroxysmal atrial fibrillation (AF). OBJECTIVE: The aim of the study was to evaluate the freedom from recurrence of AF during a 3-year follow-up period, among consecutive patients having undergone pulmonary vein isolation (PVI) with the CB-A for paroxysmal AF (PAF)...

BACKGROUND: Thyroid hormone (TH) is known to enhance arrhythmogenicity, and high-normal thyroid function is related with an increased recurrence of atrial fibrillation (AF) after catheter ablation. However, the impact of thyroid hormone replacement (THR) on AF ablation is not well known. METHODS: This study evaluated 1163 consecutive paroxysmal AF patients [160 (14%) on THR and 1003 (86%) without THR] undergoing their first catheter ablation. A total of 146 patients on THR and 146 controls were generated by propensity matching, based on calculated risk factor scores, using a logistic model (age, sex, body mass index, and left atrium size)...

PURPOSE: Although cavotricuspid isthmus-dependent atrial flutter (CTI-AFL) ablation is a highly efficacious treatment, a bidirectional CTI block cannot be achieved in some patients. In this study, we sought to determine the predictors of acute inefficacy of CTI-AFL ablation and the predictors of the radiofrequency (RF) energy time required to achieve a complete bidirectional CTI block. METHODS: All consecutive patients who underwent stand-alone CTI-AFL ablation in our institution, except patients with congenital heart disease, were included in this retrospective study...

PURPOSE: Magnetic resonance imaging (MRI) with late gadolinium enhancement is commonly performed in patients with non-ischemic LV ventricular tachycardia/ventricular premature depolarizations (non-ischemic LV-VT/VPDs) to define VT substrate prior to catheter ablation. We investigated the prevalence of abnormal voltage and VT localized to areas of the myocardium not reported to have late gadolinium enhancement (LGE) on routine pre-procedural MRI and sought to determine if quantitative MRI analysis could reduce this discordance...

PURPOSE: ICDs can improve survival in at-risk patients but no consensus exists with respect to their impact on health-related quality of life (QOL). Moreover, the data are unclear on QOL benefits in specific patient subgroups. We sought to analyze, in the INTRINSIC RV ICD trial population, health-related QOL longitudinally following ICD implant and consider impact of age, gender, and ICD shocks on QOL by employing a global measure of health-related QOL. METHODS: One thousand five hundred thirty patients had an ICD implanted...

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...
