Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Pulsed Field Ablation (PFA) is an emerging energy modality for cardiac ablation, offering shorter atrial dwell times and reduced collateral damage compared to thermal methods. However, energy‐related complications, specifically gaseous microbubble formation and hemolysis, require further evaluation.

Coexistence of Atrioventricular Nodal Reentrant Tachycardia and Idiopathic Left Ventricular Outflow-Tract Tachycardia [PDF]
, 2005 Double tachycardia is a relatively rare condition. We describe a 21 year old woman with history of frequent palpitations. In one of these episodes, she had wide complex tachycardia with right bundle branch and inferior axis morphology.

Pacing and Clinical Electrophysiology, EarlyView.Abstract Electrode design and reliable contact assessment are critical for creating durable pulsed field ablation (PFA) lesions to treat atrial fibrillation while minimizing collateral damage. This review introduces a novel “map‐and‐ablate” PFA catheter featuring flat electrodes, thermal contact assessment, and fully customizable electrode selection ...

Redesigning Pulsed Field Ablation Catheter Form Factors for Lesion Precision, Durability, and Safety
Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Pulsed field ablation (PFA) is a cutting‐edge treatment for arrhythmias that targets cardiac tissue with rapid, high‐voltage electric current pulses, resulting in irreversible electroporation. Freed from the constraints of traditional radiofrequency (RF) ablation, the non‐thermal mechanism and myocardial selectivity of PFA has improved ...

The first human experience of a contact force sensing catheter for epicardial ablation of ventricular tachycardia [PDF]
, 2014 Contact force (CF) is one of the major determinants for sufficient lesion formation. CF-guided procedures are associated with enhanced lesion formation and procedural success.We report our initial experience in epicardial ventricular tachycardia (VT ...

Pulsed Field Ablation in Patients With Cardiac Implantable Electric Devices: Vigilance Is Warranted
Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Pulsed field ablation (PFA) for the treatment of atrial fibrillation offers potential safety benefits compared to thermal ablation modalities. However, the high voltage electric pulses required to irreversibly electroporate myocardial cells present a unique clinical challenge in regard to patients with cardiac implantable electronic devices ...

The Survey of Radiation Dose in Radiofrequency Catheter Ablation
Japanese Journal of Radiological Technology, 2013 Interventional radiology (IVR) is a technique using image guidance such as X-ray fluoroscopy to perform diagnostic and therapeutic procedures. It is widespread, and its use continues to increase. Radiofrequency catheter ablation (RFCA) has a long fluoroscopy time, and ablation procedures may be repeated in a single session.
