Pulsed Field Ablation (PFA) is a revolutionary cardiac ablation technology, specifically for the treatment of atrial fibrillation (AFib), a common type of heart rhythm disorder.
Unlike traditional thermal ablation that uses extreme temperatures to disable cardiac cells, PFA uses short electrical pulses delivered at high frequency. This nonthermal technique, known as electroporation, creates tiny holes in the cell membrane, making it more permeable. The targeted cells that contribute to irregular heart rhythms die without altering the overall structure of the tissue or affecting other cell types.
The PFA technology has several advantages over traditional methods. It can be tightly targeted, eliminating unwanted damage to nearby tissue compared with thermal or RF ablation. It can also reduce procedure time from tens of minutes at each site to just a few seconds (based on pulse parameters) for the same biological response. This improved safety profile and reduced procedure time is expected to make PFA the next major trend in arrhythmia care. Clinical trials have shown promising results.
EHT Nanosecond Pulsers bring precision pulsed power to PFA and represents a significant advancement in the field of electrophysiology, offering a safer, more efficient, and effective treatment for AFib and other cardiac conditions.
