doi: 10.1016/j.hroo.2024.03.012
Figure Lengend Snippet: Preablation and postablation 3-dimensional electroanatomic mapping of the left atrium at repeat pulmonary vein isolation (PVI) with pulsed-field ablation for reisolation of reconnected veins and antral widening of still isolated veins after prior failed PVI with thermal ablation (A) and posterior wall ablation after multiple PVIs using thermal ablation with durable PVI and posterior wall scar (B). MAP = mapping.
Article Snippet: After successful LA access, a detailed high-density map was acquired using a 3-dimensional (3D) electroanatomic mapping (EAM) system (CARTO3, Biosense Webster, Irvine, CA) and dedicated mapping catheter (PentaRay/OctaRay, Biosense Webster).
Techniques: Isolation
