Cardiology CartoUnivu™ Module 1 Intergrated fluoroscopic image of the chest and 3D reconstruction Registration screen of the Carto® 3 System with CartoUnivu™ Module showing the registration fluoroscopy image. The Siemens Artis angiography system sends acquired images to the Carto® 3 system including the exact table position and current angulation of the C-arm. of the LV. Two planes (AP on the left and RAO 45° on the right) are juxtaposed side-by-side and visualized with a reconstructed 3D overlay map of the LV. The red markers highlight ablation targets in the left ventricular outflow tract region that were applied to eliminate ventricular tachycardia. 2 Fluoroscopy provides a precise image of reality. In the electrophysiology laboratory, it tracks the exact position of the cardiac catheter in real time. However, this precision comes at a price in the form of the accompanying exposure. Additionally, low levels of confidence entrap users to step more often on fluoro; with the result that radiation load is higher for everyone in the EP lab: patients, doctors, and staff alike. CartoUnivu™ Module combined with Artis system are now helping physicians resort less frequently to the knee-jerk reaction of yet another fluoroscopic shot, thereby reducing exposure times. The software module combines fluoro images and the Carto® 3 System 3D map into a single, integrated view. With the familiar fluoroscopy in the background, users intuitively develop greater confidence in the electroanatomical 3D map of the heart. They currently see both images on separate screens and have to combine them in their mind’s eye. CartoUnivu™ Module now does this for them. Reducing Unnecessary Radiation Load Developed by Biosense WebsterInc., the software stores selected fluoro images taken during the intervention and projects them behind the Carto® 3 System map as fixed images. Cine sequences can also be displayed. If the 3D model is rotated during the intervention as another angle is required, the corresponding X-ray image is also visualized behind the map if available. The software package can be installed in all Siemens angiography systems released since 2006 without additional upgrades or costs, thereby allowing earlier system generations to be equipped with this state-of-the-art technology. As a result, Siemens offers its clients optimal flexibility – also as far as the installation of other navigation systems is concerned. A wide range of interfaces can be implemented.
