Figure 1
A: Left atrium (LA) bipolar map (0.1–0.3 mV) with isolated pulmonary veins and posterior wall with low-voltage areas in the anterior wall. B: Radiofrequency lesion sets in the anterior and roof line. C: Posteroanterior 3-dimensional map of LA. D: Ablation catheter localization (black arrow) in the critical isthmus area; green arrow represents the direction of the main force vector of the ablation catheter.
Figure 2
Figure 2
A, B: Fluoroscopy shows the location of the ablation catheter in left anterior oblique (LAO) (A) and right anterior oblique (RAO) (B). C, D: Pulsed-field ablation (PFA) catheter is shown in LAO and RAO, respectively. E, F: Intracardiac echocardiography imaging shows the location of PFA catheter in the target location with proper tissue contact and a safe distance from the coronary arteries; red dot represents the expected location of the left main coronary artery. Ao = aorta; LA = left atrium; PT = pulmonary trunk.
