B-PO04-124 EFFECTS OF PULSED ELECTRIC FIELDS ON THE CORONARY VASCULATURE IN SWINE

Previous animal studies suggest a lack of significant injury to the vasculature following pulsed electric field (PEF) ablation. We sought to assess the effects of PEF on the coronary arteries in swine. We performed PEF ablations in pigs pretreated with dual antiplatelet and antiarrhythmic therapy. PEF was intracoronary using MapiT catheters (Biotronik, Berlin, Germany) or peri-coronary after epicardial access using EPT catheters (Boston...
