Pulsed field ablation tech gaining popularity in the - GlobalData Vivek Reddy discloses that he is a consultant on behalf of and owns stock in Farapulse. More recent preclinical data with newer biphasic PFA waveforms have encouragingly been shown to create contiguous, homogenous, transmural atrial lesions and to achieve relevant endpoints such as durable PV isolation.19 Importantly, each PFA waveform should be considered a unique entity and requires detailed preclinical safety and efficacy assessment. PFA is a strikingly promising and novel non-thermal ablative strategy that has the capability to overcome certain limitations of contemporary AF ablation technologies. Herein, iron-based nanoparticles (FeNPs), metallic nanoparticles, were synthesized via a facile chemical . In ventricular tissue, PFA has been shown to create large lesions with sparing of the vasculature and nerves within and adjacent to the lesion.15 Additionally, PFA has been shown to spare the esophageal mucosal and sub-mucosal layers despite deliberate application of PFA on the esophagus.16,17 PFA has also been shown to not injure the phrenic nerve despite multiple applications along its course.18 These important findings suggest that PFA has a unique safety profile that makes it extremely attractive for atrial tissue ablation. Bethesda, MD 20894, Web Policies In addition, catheter ablation can be associated with other complications such as PV stenosis, steam pops, and the risk of embolic strokes.4,5 These safety limitations are unfortunately compounded by the lack of consistent lesion transmurality, a known mechanism for AF recurrence.6 Thus, there has been a pressing need for an ablative strategy that is not only very efficacious but also extremely safe. This must be kept in mind as newer PFA technologies make their way into the clinical realm. Elad Maor - Interventional Cardiologist - Sheba - LinkedIn 2022 Oct 15. doi: 10.1007/s10840-022-01398-4.
