Delayed removal of a percutaneous left ventricular assist device for patients undergoing catheter ablation of ventricular tachycardia is associated with increased 90-day mortality.

Purpose: Assess if timing of removal of a percutaneous left ventricular assist device (pLVAD) after ventricular tachycardia (VT) ablation alters patient outcomes.

Methods: Sixty-nine patients underwent pLVAD support. Patients were divided into early (< 24 h, n = 43) and delayed (≥ 24 h, n = 26) removal groups after ablation.

Ablation of Refractory Papillary Muscle Ventricular Tachycardia Warranting Multiple Adjunctive Ablation Techniques: A Combined Approach for Success.

A 27-year-old male presented to our institution with recurrent unifocal premature ventricular contraction/nonsustained ventricular tachycardia (VT) with associated cardiomyopathy. The patient had undergone three prior ablation procedures with continued arrhythmia. Mapping led to identification of the VT arising from the basal aspect of the left ventricular anterolateral papillary muscle.

Tachycardia with alternating pacemaker spikes: Is it pacemaker malfunction?

A 67 year old female with diabetes mellitus type 2, chronic kidney disease, ischemic cardiomyopathy, status post biventricular implantable cardioverter-defibrillator presented to the Heart Failure clinic for routine follow up with a tachycardia with alternating pacemaker spikes.

Incidence, Predictors, and Significance of Ventricular Arrhythmias in Patients With Continuous-Flow Left Ventricular Assist Devices: A 15-Year Institutional Experience.

Objectives: The aim of this study was to evaluate the incidence, predictors, and associated mortality of pre-implantation, early, and late ventricular arrhythmias (VAs) in patients receiving continuous-flow left ventricular assist devices (CFLVADs).

Background: VAs are common both pre- and post-implantation of left ventricular assist devices. Limited data exist on their prognostic impact in contemporary CFLVADs.

Esophageal Temperature Monitoring During Radiofrequency Ablation of Atrial Fibrillation: A Meta-Analysis.

Atrio-esophageal fistula is an infrequent but devastating complication of catheter-based ablation of atrial fibrillation (AF). Thermal esophageal injury may be the precursor of atrio-esophageal fistula. Here, we evaluated the role of esophageal temperature monitoring in preventing thermal esophageal injury during pulmonary vein isolation for AF with radiofrequency energy.
