A physician friend emailed me this abstract of a study noted in the JACC. Anyone heard about it? "Ablation of Atrial Fibrillation With Pulsed Electric Fields" Sorry I can't get the link to work - have forgotten how to do that! But it sounds very promising! Look forward to hearing from those in the know! https://www.afibbers.org/forum/read.php?9,162557,162557#msg-162557 Wed, 26 Aug 2026 15:05:16 +0000 Phorum 5.2.23 https://www.afibbers.org/forum/read.php?9,162557,162635#msg-162635 https://www.afibbers.org/forum/read.php?9,162557,162635#msg-162635
There is a new mapping catheter that IMO looks promising because it measures in a non-contact mode detailed anatomy at nearly the same time as electrical activity is measured. Here is a paper with videos of a couple of patients from Imperial/UK. Sounds promising but still early in trials. What they wrote made sense in that all current mapping techniques require compromises on knowing the atrial geometry accurately (only approximate for Cardioinsight, Abbot-Topera, etc) or that voltage mapping can be sequentially gathered and spliced together accurately along with geometry. All in a moving chamber. Having near simultaneous measurement of geometry (48 ultrasound sensors) and voltage (48 electric field sensors) should be more accurate for both geometry and electrical activity and make it a lot easier to find drivers and triggers.

Electroporation

Seems like this technique seeks to move ablation back into the pulmonary veins rather than encircling them as is done with RF and cryo. What about ablation outside the PVs, as we all know is necessary in some folks for the permanent relief of atrial arrhythmia? I don't see an answer to that. Also, the paper mentions ventricular fibrillation as a possible side effect (during the procedure it would seem). That's certainly scary.

This is VERY early data. Certainly worth following, but ten'll get you twenty that it's not going to be busting into EP labs anytime soon. FIRM continues to serve as a reminder about "irrational exuberance" when it comes to AF. I still maintain that method (RF/cryo) and skill of operator are the deciding factors in AF ablation for now and the foreseeable future, and not any "shiny new objects" on the horizon.]]> wolfpack AFIBBERS FORUM Thu, 31 May 2018 20:10:02 +0000 https://www.afibbers.org/forum/read.php?9,162557,162559#msg-162559 https://www.afibbers.org/forum/read.php?9,162557,162559#msg-162559 mwcf AFIBBERS FORUM Thu, 31 May 2018 19:08:35 +0000 https://www.afibbers.org/forum/read.php?9,162557,162558#msg-162558 https://www.afibbers.org/forum/read.php?9,162557,162558#msg-162558
