Pulsed Field Ablation

Pulsed Field Ablation (PFA), a new form of cardiac catheter ablation, has been shown to treat some forms of atrial fibrillation with good effect. With faster procedure times than conventional techniques, this therapy carries less risk to the heart’s adjacent structures, making a generally safer procedure. The TGH Electrophysiology Center of Excellence laboratory uses The PulseSelect™ pulsed field ablation (PFA) system, which is a cardiac ablation system that enables both mapping and precise lesion delivery using biphasic waveform optimization. This technology uses electrical signals that isolate and ablate specific heart cells in a precise pattern, resulting in a quicker and safer procedure. Recent studies have proven this therapy to be effective and minimize the risks associated with thermal ablations (radiofrequency and cryo), like damaging structures surrounding the heart.
