(A) The fully-deployed endocardial PEF catheter is shown over a guidewire with its splines as it exits the transseptal sheath. (B) The in vivo fluoroscopic view depicts the fully deployed ablation catheter positioned at the right-superior PV ostium. The PV is outlined by contrast injection performed through the sheath. Pacing catheters in coronary sinus and right ventricular (RV) apex are also present. (C) The ablation zone of a PEF application is modeled: in this cross-sectional, long-axis view of the LA-PV junction, the shaded red area represents the circumferential ablation zone. LA = left atrium; PEF = pulsed electric field; PV = pulmonary vein.
