Figure 3 Radiofrequency ablation and left atrial appendage (LAA) occlusion for atrial fibrillation (AF). Under intracardiac echocardiography guidance, the septum was punctured (A), followed by AF ablation of the left (B) and right (C) pulmonary veins. Completion of AF fragmentation potential ablation is shown in (D). LAA angiography in the RAO 30°/CRA 20° view is shown in (E), with an additional RAO 30°/CAU 20° view in (F). Panel (G) shows the LAA after occlusion, and (H) demonstrates intracardiac ultrasound assessment of blood flow following the procedure.
