INTRODUCTION: Despite the overall safety, transvenous lead extraction (TLE) remains a challenging procedure with inherent risks, where surgery can still be required in elective cases. In this study, we report our experience with a minimally invasive "hybrid" approach, defined as a procedure performed by an electrophysiologist with the support of a cardiac surgeon in the same operative session. METHODS AND RESULTS: We reported 12 cases of planned hybrid lead extraction; minithoracotomy and thoracoscopy were performed on 10 (83%) and 2 (17%) patients, respectively...

INTRODUCTION: Identification of wavefront propagation pattern during AF remains challenging in ablation procedures. We sought to test a novel combination of a new mapping technology called Ripple Map and high density mapping to distinguish focal and reentrant activation during atrial fibrillation (AF). METHODS AND RESULTS: Subjects were patients undergoing ablation for persistent AF. If AF remained after isolation of the pulmonary veins, the left atrium (LA) was mapped by a high-density mapping catheter for later analysis, after which ablation was continued using a conventional stepwise approach...

INTRODUCTION: The ligament of Marshall may hinder the creation of mitral isthmus (MI) block or pulmonary vein (PV) isolation (PVI) in radiofrequency (RF) catheter ablation of atrial fibrillation (AF). We aimed to assess the benefit of RF ablation targeting the vein of Marshall (VOM) in failed cases of MI block or PVI. METHODS AND RESULTS: We reviewed the medical records of patients who underwent RF ablation targeting the VOM after failed MI ablation or left PVI using the conventional method, which included circumferential point-by-point ablation around the PV antrum and carina, or endocardial MI and epicardial distal coronary sinus (CS) ablation for MI block...

Dual chamber pacemakers have inbuilt advanced safety systems such as ventricular safety standby (crosstalk detection) to prevent ventricular oversensing resulting in inappropriate pacing inhibition. We describe a case where this safety mechanism does not reliably work and the management required to rectify the situation in an educational format. This article is protected by copyright.

INTRODUCTION: The guidelines suggest that an adjuvant substrate modification in addition to pulmonary vein isolation (PVI) may be needed for persistent atrial fibrillation (PerAF) assuming that catheter ablation is less successful for PerAF than paroxysmal AF (PAF). To revisit the above assumption, we compared the outcome of the same catheter ablation strategy between PAF and PerAF. METHODS AND RESULTS: Two-hundred and thirty-three consecutive patients (mean age 60±10 years, 53 PerAF and 8 long-lasting PerAF) without structural heart disease underwent catheter ablation of AF by the same strategy using an empiric thoracic vein isolation (a wide circumferential PVI plus empiric superior vena cava isolation) as a major part of the strategy without any adjuvant substrate modification...

INTRODUCTION: 3D electroanatomical mapping (EAM) is an established tool facilitating catheter ablation. In this context the novel Rhythmia system sets a new bar in fast high-resolution mapping. The aim of this study was to directly compare point-by-point versus rapid ultra high-resolution EAM in patients scheduled for ablation of atrial fibrillation (AF) with focus on procedural data, acute success and mid-term clinical outcome. METHODS AND RESULTS: A total number of 74 consecutive patients (48/74 male) with symptomatic AF were scheduled to undergo pulmonary vein isolation (PVI) using either Carto or Rhythmia...

INTRODUCTION: Pulmonary vein isolation (PVI) is currently the gold standard for catheter ablation of atrial fibrillation (AF). The mechanism for AF-maintenance is still controversial. The concept of rapidly-activating spiral rotors perpetuating AF has led to the development of several rotor-mapping systems. We present our experience with focal impulse and rotor modulation (FIRM) using a 64-electrode basket catheter and computational system and evaluate its feasibility in conjunction with PVI to treat AF...

Long-term right ventricular (RV) apical pacing has been associated with an increased risk of death, heart failure (HF) and atrial fibrillation (AF). Alternative sites for RV pacing have not proven to be superior to right ventricular apical pacing. Cardiac resynchronization therapy (CRT) using a biventricular (BiV) lead system is indicated for patients with a low left ventricular ejection fractions (LVEF) and QRS prolongation, but there remains about a 25-30% non-response rate. CRT has been less effective for non-LBBB conduction delay and with normal/low normal left ventricular (LV) function...

INTRODUCTION: Radiofrequency isolation of pulmonary vein can be accompanied by transient sinus bradycardia or atrioventricular nodal (AVN) block, suggesting an influence on vagal cardiac innervation. However, the importance of the atrial fat pads in relation with the vagal innervation of AVN in humans remains largely unknown. This article is protected by copyright.

BACKGROUND: Pulmonary vein stenosis (PVST) can occur after first-generation cryoballoon ablation. This study aimed to evaluate the incidence, severity, and characteristics of PVST after second-generation cryoballoon ablation. METHODS: In total, 103 patients underwent PV isolation of paroxysmal atrial fibrillation using second-generation cryoballoons with a single big-balloon 3-minute freeze technique. Cardiac enhanced multidetector computed tomography (MDCT) was performed both before and a median of 6...

Ventricular tachycardia (VT), ventricular fibrillation (VF) and electrical storm are commonly encountered emergency conditions in cardiac and surgical intensive care units. In most cases, recurrent ventricular arrhythmias or electrical storm are associated with a heightened sympathetic tone. These arrhythmias can be difficult to treat and may be refractory to beta-blockade, antiarrhythmic therapy, sedation, and mechanical hemodynamic support. While monomorphic ventricular tachycardia and PVC-triggered polymorphic ventricular tachycardia may sometimes be amenable to successful ablation, some patients may be too critically ill to make such an approach feasible...

INTRODUCTION: Bipolar voltage criteria to delineate LA scar have been derived using PBP contact electroanatomical mapping. It remains unclear how PBP-derived LA scar correlates with ME-FAM derived scar. We aimed to correlate scar and bipolar voltages from left atrial (LA) maps created using point-by-point (PBP) versus multi-electrode fast automated mapping (ME-FAM). METHODS AND RESULTS: In consecutive patients undergoing repeat AF ablation, 2 separate LA maps were created using PBP and ME-FAM during sinus rhythm before ablation...

INTRODUCTION: The autonomic nervous system has been proven to play a major role in the onset of atrial fibrillation (AF), along with a predisposing substrate and a specific trigger event usually consisting of a premature supraventricular ectopic beat (SVEB). By means of heart rate variability (HRV) analysis, we investigated the activity of the autonomic nervous system before SVEBs non-triggering and triggering AF. METHODS AND RESULTS: We evaluated 28 patients with at least one episode of sustained AF (> 30 seconds) recorded during 24-hour Holter monitorings...

BACKGROUND: Implantable cardioverter defibrillators (ICDs) must establish a balance between delivering appropriate shocks for ventricular tachyarrhythmias and withholding inappropriate shocks for lead-related oversensing ("noise"). To improve the specificity of ICD therapy, manufacturers have developed proprietary algorithms that detect lead noise. The SecureSense(TM) RV Lead Noise discrimination (St Jude Medical, St Paul, MN) algorithm is designed to differentiate oversensing due to lead failure from ventricular tachyarrhythmias and withhold therapies in the presence of sustained lead-related oversensing...

BACKGROUND: There have been an increasing number of atrial fibrillation (AF) patients with Watchman® left atrial appendage occlusion (LAAO) device, requiring catheter ablation (CA) for maintenance of normal sinus rhythm. In this study, we describe our experience with the feasibility and safety of CA in patients with a preexisting Watchman LAAO device. METHODS: This was a retrospective multicenter AF registry of 60 patients with Watchman® LAAO device who underwent CA for AF...

BACKGROUND: Conduction disorders requiring permanent pacemaker (PPM) implantation are a known complication of trans-catheter aortic valve implantation (TAVI). Indications for permanent pacing in this setting are still controversial. The study aim was to characterize the natural history of conduction disorders related to TAVI, and to identify predictors for long term pacing dependency. METHODS: Consecutive patients who underwent TAVI were included in this prospective observational study...

Slowing of the tachycardia with increase in cycle length and increase in VA time with ipsilateral bundle branch block is characteristic feature of accessory pathway mediated AVRT. Contralateral bundle branch block has no effect on the tachycardia as it is not a part of the tachycardia circuit. We present an interesting phenomenon in which contralateral bundle branch block resulting in tachycardia slowing in a case of WPW syndrome. This article is protected by copyright.
