Description : On the screen you will see a composite image that is generated by combining the pre ablation CT image with the 3D electroanatomic map. The red dots you see are the ablation points in the cavity (or antral) portion of the pulmonary veins. A combination of x-ray, 3D mapping, and intracardiac echo are used in assessing the point to point location of the ablation catheter and the delivery of the radiofrequency energy.
