Echonavigator^® during left atrial appendage occlusion. A demonstrates how the point of interest for potential transseptal crossing along the interatrial septum is marked in the Echo image. B demonstrates in the X-ray-view, that the wire is located cranial of the Crista terminalis, that initially was assigned in the Echo image. C depicts an ellipsoid ring, representing the landing zone for the occluder device marked yellow in the X-plane view of the 2D Echo image. D displays the deployment of the lobe of the left atrial appendage occluder, detecting that correct device size was chosen. E shows this ellipsoid marker right in between the lobe and the disc of the occluder after deployment of the disc. The red marker represents the location of the circumflex coronary artery. F shows the final result after disconnecting the guiding system from the occcluder. The left panel gives a nice 3D overview of the site of implantation, displaying the difference of the landing zone (yellow circle) and the orifice area of the left atrial appendage.
