Intracardiac Echocardiography during Catheter-Based Ablation of Atrial Fibrillation
Figure 3
Reconstruction of left pulmonary veins (a and b) and right pulmonary veins (c and d) using ICE in combination with the integrated software algorithm CARTOMerge. A dedicated ICE probe provides real-time anatomic images that are integrated with preprocedural acquired CT images. On ECG-gated ICE images, the anatomy of the PVs can be annotated (a and c), creating a 3D shell, and subsequently is integrated with the dedicated algorithm (b and d).
