Coronary Spasm Due to Pulsed Field Ablation: A State‐of‐the‐Art Review

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT With the ever‐growing population of patients undergoing cardiac ablation with pulsed electric fields, there is a need to understand secondary effects from the therapy. Coronary artery spasm is one such effect that has recently emerged as the subject of further investigation in electrophysiology literature.

Fundamentals of System Design for Cardiac Pulsed Field Ablation: Optimization of Safety, Efficacy, and Usability

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT The goal of a cardiac pulsed field ablation (PFA) system is to provide safe, effective, and usable therapy for the treatment of cardiac arrhythmias. Achieving this goal is a complex exercise in system design, requiring optimization of catheter, waveform, and dosing. This optimization is often iterative, as myriad design factors are balanced to

Lesion Formation in Cardiac Pulsed‐Field Ablation: Acute to Chronic Cellular Level Changes

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT As pulsed‐field ablation (PFA) emerges as a promising therapy for atrial arrhythmias, an understanding of the cellular injury to cardiac tissue is critical to evaluating and interpreting results for each PFA system. This review aims to detail the mechanism of cell death for PFA, compare the cell death mechanism to thermal ablation modalities ...

Functional Substrate Mapping Using Atrial Decrement Evoked Potentials to Predict Critical Isthmus of Atrial Tachycardia

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Recent reports highlighted the role of functional substrate mapping during sinus rhythm to predict the critical isthmus of left atrial tachycardias (AT). In this article, we reported a case of a 63‐year‐old female patient who was admitted with recurrent AT after pulmonary vein isolation.

Fascicular/Purkinje Tissue Colocalized With Scar in Cardiomyopathy Patients Undergoing Ventricular Fibrillation Ablation

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Ventricular fibrillation (VF) is a poorly understood arrhythmia that is one of the main mechanisms of sudden cardiac death in patients with structural heart disease (SHD). Fascicular and Purkinje tissue (FPT) has been implicated in VF.

Catheter ablation of repetitive ventricular tachycardia in patients with ischemic heart disease – our experience

open access: yesZdravniški Vestnik, 2017
Ventricular tachycardia (VT) poses a significant risk for sudden death and heart failure exacerbation in patients with ischemic heart disease. Catheter-based radiofrequency ablation is the last treatment option for patients with frequent VT recurrences ...
