2020 AF Symposium: 5 Abstracts on Pulsed Field Ablation
The 2020 AF Symposium abstracts are one-page descriptions of A-Fib research, both published or unpublished. The abstracts are supplemental to the Symposium live presentations, panels discussions and spotlight sessions. This year the printed digest contained 55 abstracts. I choose only a few to summarize.
My Summaries of Select PFA Abstracts
Pulsed Field Ablation (PFA) was the single most important topic at this year’s Symposium. I summarized five of the PFA abstracts of most interest to A-Fib patients.
• Lesion Durability and Safety Outcomes of Pulsed Field Ablation
The durability of PFA lesions is the focus of Dr. Vivek Reddy’s abstract. His research study followed 113 patients who each received a PFA ablation.
• Pulsed Field Ablation with CTI Lesions Terminates Flutter in a Small Study
The use of Pulsed Field Ablation (PFA) may significantly improve CTI ablation lesions to block the Flutter signal. (CTI: Cavo-Tricuspid Isthmus)
• Durability of Pulsed Field Ablation Isolation Over Time: Preliminary Study
Pulsed Field Ablation (PFA) is a new treatment. This study asked the question of whether PFA electrical isolation (lesions) regresses over time.
• Pulsed Field Ablation vs RF Ablation: A Study in Swine
PFA is “tissue-specific”. This study tested if surrounding non-heart tissue (the esophagus) would be affected. PFA ablation was compared to RF ablation. Swine (pigs) were used so tissue could be dissected and examined.
• Using MRI to Check Pulsed Field Ablations (PFA)
Normally, during a RF or cryo ablation, doctors move the esophagus as far away as possible from where they are ablating. In this study they took no such precautions.
