Biophysics of Electroporation and Pulsed Field Ablation

Cardiac Electrophysiology Clinics
High-voltage electric fields can lead to increased permeability of cell membranes-a phenomenon called electropermeabilization. The mechanisms contributing to this effect are electroporation, membrane lipid peroxidation, oxidative stress, and structural changes in membrane proteins.

Lesion Characteristics of Pulsed Field Ablation

Cardiac Electrophysiology Clinics
Pulsed field ablation (PFA) has emerged as a promising, nonthermal technique for arrhythmia ablation, leveraging high-voltage electrical fields to induce electroporation and create precise ablation lesions. Unlike traditional thermal methods such as radiofrequency ablation (RFA) and cryoablation, PFA selectively targets myocardial cells while sparing ...

Catheters and Tools with Pulsed Field Ablation—Pulmonary Vein Isolation and Nanosecond Pulse Field Ablation

Cardiac Electrophysiology Clinics
Pulse field ablation (PFA) has gained attention in the field of atrial fibrillation catheter treatment recently. All currently used or developed technologies use ultrashort pulses (on the order of microseconds). The Emerging CellFX System (Pulse Biosciences, Inc, Inc) utilizes nanosecond PFA (nsPFA) and is thus several orders of magnitude shorter than ...
