Article Abstract
Ventricular arrhythmias (VA) constitute well-known problems in patients with left ventricular assist devices (LVADs), with incidence ranging from 18% to as high as 52%. Catheter ablation has become a common therapeutic intervention to treat drug-refractory VA, particularly with the increase and more widespread use of durable LVADs to bridge patients to transplantation or as destination therapy. In this article, we focus on etiology, mechanisms, periprocedural management, and mapping and ablation techniques in patients with LVADs and VA.

Wave Speed Mapping as a Complementary Tool for Identifying Ventricular Tachycardia Substrate.

Department of Cardiology, Stefan Cardinal Wyszynski Province Specialist Hospital, Lublin, Poland.
Introduction: Wave speed (WS) mapping, enabled by omnipolar technology, allows for real-time visualization of local conduction velocity (CV). Its utility in ventricular tachycardia (VT) ablation has not been fully characterized.
Methods And Results: We describe a case series of patients undergoing VT ablation in which WS mapping was applied alongside established techniques such as peak frequency (PF) mapping and isochronal late activation mapping (ILAM).

Background And Aims: Aim of this study was to assess the risk of hemolysis, the extent of myocardial and neural injury after monopolar, monophasic pulsed field ablation (PFA) using a lattice-tip catheter in comparison to single-shot PF ablation platforms employing bipolar, biphasic waveforms.
Methods: This prospective study included consecutive patients undergoing PFA for atrial fibrillation (AF) using the Affera™ mapping and ablation system (n=40). Biomarkers for hemolysis (haptoglobin, LDH, bilirubin), myocardial injury (high-sensitive troponin T, CK, CK-MB), neurocardiac injury (S100), and renal function (creatinine) were assessed pre- and within 24 hours post-ablation.

Tuberculosis (TB) outcomes vary widely, from asymptomatic infection to mortality, yet most animal models do not recapitulate human phenotypic and genotypic variation. The genetically diverse Collaborative Cross mouse panel models distinct facets of TB disease that occur in humans and allows identification of genomic loci underlying clinical outcomes. We previously mapped a TB susceptibility locus on mouse chromosome 2.

Background: High % of low-voltage area (LVA), a surrogate of scar, is associated with atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI). Noninvasive biomarkers of LVA are a medical need for PVI decision.
Objective: We aimed to identify the proteome profile of plasma extracellular vesicles (EVs) associated with high % LVA, their cellular origin, and their regulation by hyperglycemia.

Background: Frequent premature atrial complexes (PACs) can increase the risk of atrial fibrillation or atrial tachycardia, and pharmacological therapy can be challenging.
Objective: To report the use of three-dimensional electro-anatomical mapping of PAC originating from the right atrial free wall and treatment by radiofrequency ablation in three horses.
