High impedance alert with safety switching: An unreported hazard of hybrid pacing systems.

J Cardiovasc Electrophysiol 2019 Apr 14. Epub 2019 Apr 14.

Evans Department of Medicine, Cardiovascular Medicine Section, Arrhythmia Service, Boston University School of Medicine, Boston, Massachusetts.

Several Boston Scientific pacemaker models have a known issue with intermittent oversensing of the minute ventilation sensor when paired with non-Boston Scientific leads. Several of our patients with these hybrid systems have had transient out of range impedances and oversensing after safety switching which we suspected may be related. A retrospective analysis of 395 patients who had pacemakers implanted between 2015-2017 found that transient out of range impedances with safety switching was present in 9% of Boston Scientific pacemakers paired with Abbott or Medtronic leads compared with 0% in other device-lead combinations (P = 0.

Update on catheter ablation research from the 2019 ehra congress.

J Cardiovasc Electrophysiol 2019 Apr 14. Epub 2019 Apr 14.

Division of Cardiology, Pauley Heart Center, Virginia Commonwealth University, Richmond, VA.

The 2019 European Heart Rhythm Association (EHRA) Scientific Meetings released several Late Breaking Clinical Trials that define important results for the fields of catheter ablation of atrial fibrillation (AF) and ventricular tachycardia (VT). Three independent multicenter randomized controlled trials have confirmed that AF ablation with point-by-point radiofrequency energy or cryoballoon technology are both equally and highly effective, and significantly superior to antiarrhythmic drug therapy in reducing recurrent AF episodes and preventing arrhythmia-related hospitalizations. Edoxaban has been shown a viable option for periprocedural oral anticoagulation in patients undergoing catheter ablation of AF in a large multicenter randomized study, with outcomes similar to uninterrupted warfarin.

Silent cerebral lesions and cognitive function after pulmonary vein isolation with an irrigated gold-tip catheter: REDUCE-TE Pilot study.

J Cardiovasc Electrophysiol 2019 Mar 7. Epub 2019 Mar 7.

Hôpitaux Universitaires de Genève, Geneva, Switzerland.

Introduction: Stroke is one of the most feared complications during catheter ablation of atrial fibrillation (AF). While symptomatic thromboembolic events are rare, magnetic resonance imaging (MRI) may identify asymptomatic (ie, silent) cerebral lesions (SCLs) following pulmonary vein isolation (PVI) procedures.

Methods And Results: The REDUCE-TE Pilot was a prospective multicenter, single-arm observational study investigating the incidence of SCL in patients with symptomatic paroxysmal AF undergoing PVI with a novel gold-tip, externally irrigated ablation catheter. Read More

Percutaneous left ventricular assist device support during ablation of ventricular tachycardia: A meta-analysis of current evidence.

J Cardiovasc Electrophysiol 2019 Mar 7. Epub 2019 Mar 7.

Department of Cardiology, UT Southwestern Medical Center, Dallas, Texas.

Introduction: Catheter ablation of ventricular tachycardia (VT) can be an effective therapy to reduce VT burden, but often it is limited by the potential for hemodynamic instability. Percutaneous left ventricular assist devices (pLVADs) have been used to maintain hemodynamic support during VT ablation but the evidence regarding its clinical impact has been inconclusive.

Methods And Results: We sought to assess the clinical impact of pLVAD when used in VT ablation by conducting a meta-analysis of the current evidence. Read More

Relationship between atrial scar on cardiac magnetic resonance and pulmonary vein reconnection after catheter ablation for paroxysmal atrial fibrillation.

J Cardiovasc Electrophysiol 2019 Mar 7. Epub 2019 Mar 7.

Department of Cardiovascular Imaging, Hôpital Cardiologique du Haut-Lévêque, CHU de Bordeaux, Pessac, France.

Introduction: Pulmonary vein (PV) reconnection is frequent in patients showing atrial fibrillation (AF) recurrence after PV isolation (PVI). Its detection with cardiac magnetic resonance (CMR) may help predict outcome and guide redo procedures. We assessed the relationship between scar on CMR and PV reconnection after catheter ablation for paroxysmal AF. Read More
