Figure Lengend Snippet: Electroanatomical mapping and pulsed-field ablation using the balloon-in-basket catheter via the superior vena cava approach. ( A ) Pre-ablation voltage map obtained with the BiB-PFA catheter during atrial fibrillation rhythm (posteroanterior view). ( B ) EnSite™ X (Abbott) image during application to the left superior pulmonary vein at 1800V (left lateral view). ( C ) Fluoroscopic image during application to the left superior pulmonary vein (20-degree left anterior oblique view). ( D ) EnSite™ X image during application to the left atrial posterior wall at 1800V (right lateral view). During this application, electrodes facing the posterior wall were selected (No. 1, 6–8), while those facing the anterior wall were deselected (No. 2–5). ( E ) Fluoroscopic image during application to the left atrial posterior wall (20-degree right anterior oblique view). ( F ) Post-ablation voltage map obtained with the BiB-PFA catheter during sinus rhythm (posteroanterior view). BiB, balloon-in-basket; CS, coronary sinus; LAA, left atrial appendage; LIPV, left inferior pulmonary vein; LSPV, left superior pulmonary vein; PFA, pulsed field ablation; RIPV, right inferior pulmonary vein; RSPV, right superior pulmonary vein.
