Pulsed corona discharge behavior

, 1991
Very intense corona discharges can be produced with pulsed high voltage. In a wire cylinder geometry we studied this peculiar type of corona which behaves very differently from DC corona.

First United States Experience With Focal Pulsed‐Field Ablation Using the FARAPOINT Catheter for Refractory Ventricular Tachycardia

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Drug‐refractory ventricular tachycardia (VT) after failed radiofrequency (RF) ablation remains a clinical challenge. Pulsed‐field ablation (PFA) is expanding to ventricular applications, but United States experience with focal pulsed‐field‐only catheters in VT is sparse, and pulsed‐field platforms are not equivalent across ...

Feasibility, Safety, and Efficacy of Pulsed Field Ablation for Ventricular Arrhythmias: Insights From a Large Health System Registry in the United States

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulsed field ablation (PFA) is an emerging non‐thermal ablation modality with proven safety in atrial arrhythmia ablation. However, data on its performance for ventricular arrhythmias (VA) remain limited. Objective To evaluate the feasibility, safety, and efficacy of PFA for complex VA in a multicenter real‐world US registry ...

Learning Curve of Pentaspline Pulsed‐Field Ablation With Posterior Wall Isolation for Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pentaspline pulsed‐field ablation (PFA) has emerged as a novel modality for pulmonary vein isolation (PVI) and posterior wall isolation (PWI) in persistent atrial fibrillation (AF). However, the learning curve associated with combined PVI + PWI and the contribution of anatomical factors to acute lesion completeness remain ...

A Comparison of Safety and Outcome Using Three Different Sedation Strategies During Pulsed Field Ablation for Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulsed field ablation (PFA) is an emerging modality for atrial fibrillation (AF) ablation. However, adequate sedation of patients during treatment is imperative. Objective Our aim was to compare safety and outcome after deep sedation (DS) managed by electrophysiology staff (EP‐DS), DS by an anaesthesia nurse (AN‐DS), and general ...

Pulmonary Vein Isolation Alone Versus Adjunctive Ablation for Paroxysmal Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
Clinical Outcomes of Pulmonary Vein Isolation Alone Versus Additional Lesion Sets in Paroxysmal Atrial Fibrillation ABSTRACT Background Pulmonary vein isolation (PVI) is the standard ablation strategy for paroxysmal atrial fibrillation (PAF). Despite guideline recommendations favoring PVI alone in PAF, some operators routinely perform extra pulmonary ...

Erythrocyte ‘Feierzeit’ reaction: Novel filamentous and vesicular response to n‐butyl acetate

Journal of Microscopy, EarlyView.
Abstract Human erythrocytes (red blood cells; RBCs) undergo spontaneous disassembly after several hours of exposure to n‐butyl acetate (nBA). Images of the morphological changes were captured in time‐lapse sequences using differential interference contrast (DIC) light microscopy.
