using intracardiac echo probe in the heart

Description :You will see a recreated image of the left atrium and pulmonary veins that has been obtained from the raw pre-procedure cardiac CT data. This image will be integrated with the three dimensional electroanatomic map of the left atrium and pulmonary veins to obtain a composite image. This helps to improve the accuracy of the map created and results in better anatomic orientation, to minimize complications. At the bottom of the screen you will see the intracardiac echo image of the right atrium. By moving the probe clockwise or counterclockwise, various areas of the left atrium and pulmonary veins can be seen. Before beginning the ablation, the doctor checks many things the presence of fluid in the sac around the heart, the presence of a blood clot in a portion of the heart called the left atrial appendage, left lower chamber wall motion, the openings of all the pulmonary veins, the posterior (or rear) wall of the heart, and any clotting in the transseptal sheaths. The heart muscle is monitored on a continual basis and checked for punctures and buildup of blood between the heart muscle and pericardium.
