BACKGROUND: The perioperative anticoagulation management for subcutaneous implantable cardioverter defibrillator (S-ICD) is still evolving. OBJECTIVE: To assess whether it is safe to perform S-ICD implantation with uninterrupted warfarin. METHODS: This is a single-center retrospective review of patients undergoing S-ICD implantation during 10/2012 to 6/2017. The most common indication for the implantation was primary prevention of sudden cardiac death...

BACKGROUND: In the chronic atrioventricular block (CAVB) dog model, beat-to-beat variation of repolarization in the left ventricle (LV) quantified as short-term variability of the left monophasic action potential duration (STVLVMAPD) increases abruptly upon challenge with a pro arrhythmic drug. This increase occurs before the first ectopic beat (EB), specifically in subjects that demonstrate subsequent repetitive Torsade de Pointes arrhythmias (TdP). OBJECTIVE: Demonstrate that STV is feasible to monitor arrhythmic risk through the use of the intracardiac electrogram (EGM) derived from the right ventricle (RV) lead from pacemakers or implantable cardioverter defibrillators (ICD)...

BACKGROUND: Angiotensin-neprilysin inhibition as compared to angiotensin inhibition decreased sudden cardiac death in reduced ejection fraction heart failure (rEFHF). The precise mechanism remains unclear. OBJECTIVE: To explore the effect of angiotensin-neprilysin inhibition on ventricular arrhythmias as compared to angiotensin inhibition in rEFHF patients with an implantable cardiac defibrillator (ICD) and remote monitoring. METHODS: We prospectively included 120 patients with ICD and: 1) New York Heart Association functional class≥ II, 2) left ventricular ejection fraction (LVEF) ≤40%, 3) remote monitoring...

BACKGROUND: There is limited experience of surgical epicardial access in the contemporary era of ventricular tachycardia ablation after prior cardiac surgery. OBJECTIVE: To describe our institutional experience with surgical epicardial access, the influence of surgical approach and compare outcomes to a propensity-matched percutaneous epicardial access control group. METHODS: A retrospective study of consecutive surgical epicardial VT ablation cases from a single center was performed...

BACKGROUND: Cardiac resynchronization therapy (CRT) requires a high % of ventricular pacing (%Vp) to maximize its clinical benefits. Atrial fibrillation (AF) has been shown to reduce %Vp in CRT due to competition with irregular intrinsic atrio-ventricular (AV) conduction. We report the results of a prospective randomized cross-over trial evaluating the amount of effective CRT delivered during AF with a novel algorithm (eCRTAF). OBJECTIVE: To determine whether eCRTAF increases the amount of effective CRT delivered during AF when compared to a currently available rate regularization algorithm...

BACKGROUND: Major complication rate of transvenous lead extraction (TLE) is estimated around 1-2.0%. Laceration of the central veins can be fatal. OBJECTIVES: to define the incidence and extent of venous injuries on a microscopic level after TLE and compare it with the incidence of clinically documented events of venous laceration. METHODS: We studied all patients who underwent TLE at our tertiary center within 30 months via a variety of techniques...

BACKGROUND: In patients with cardiac implanted electronic devices (CIEDs) detection of new atrial fibrillation (AF) is associated with an increased risk of stroke. OBJECTIVE: To characterize daily AF burden at first detection and the rate of temporal transition to higher device detected AF burden. METHODS: A pooled analysis of data from three prospective studies was analyzed and 6580 patients (mean age 68±12 years, 72% male) with no history of AF and no anticoagulants at baseline were identified...

His bundle pacing (HBP) prevents ventricular dyssynchrony and its long-term consequences by preserving normal electrical activation of the ventricles. Since the original description of permanent HBP in 2000, the adoption of HBP has increased over the last several years. However the reporting of procedural and clinical outcomes to date is not uniform. This paper is a collaboration between several implanters with significant experience in HBP to establish a uniform set of definitions encompassing the different forms of HBP, as well as define a standardized approach to gathering data endpoints to ensure consistency in reported outcomes...

BACKGROUND: The effect of uninterrupted oral anticoagulant use in patients with chronic kidney disease (CKD) during catheter ablation for atrial fibrillation (AF) is not fully understood. OBJECTIVE: The present study aimed to evaluate safety and efficacy of periprocedural uninterrupted direct oral anticoagulant (DOAC) use compared with uninterrupted warfarin in patients undergoing catheter ablation for AF, stratified by various renal function groups. METHODS: A total of 2,091 patients were retrospectively included...

BACKGROUND: Pulmonary vein isolation (PVI) is a cornerstone ablation strategy in the management of patients with atrial fibrillation (AF). Consensus guidelines and statements recommend PVI during the index catheter ablation procedure in patients with paroxysmal and persistent AF. OBJECTIVE: The objective of this analysis was to evaluate patients with persistent and long-standing persistent AF who were treated with the cryoballoon ablation catheter by PVI technique...

BACKGROUND: Although large randomized clinical trials have found that primary prevention use of an implantable cardioverter-defibrillator (ICD) improves survival in patients with cardiomyopathy and heart failure symptoms, patients who receive ICDs in practice are often older and have more comorbidities than patients who were enrolled in the clinical trials. In addition, there is a debate among clinicians on the usefulness of electrophysiological study for risk stratification of asymptomatic patients with Brugada syndrome...

BACKGROUND: Anatomical macroreentrant atrial tachycardias (MATs) are conventionally reported to depend on the cavotricuspid isthmus (CTI), the mitral isthmus (MI), or the left atrial roof, and are commonly seen following catheter ablation (CA) for atrial fibrillation (AF). OBJECTIVES: To define the precise circuits of anatomical MAT with ultra-high resolution mapping. METHODS: In 57 patients (mean age, 62 years; 10 female) who developed at least one anatomical MAT, we analyzed 88 MAT circuits including 16 peri-tricuspid, 42 peri-mitral, and 30 roof-dependent circuits, using high-density mapping and entrainment...
