As in figure 2, the chest fluoroscopic image and the 3D map of the LV are integrated, but the 3D map is shown in a solid (non-transparent) mode. The CartoUnivu™ Module can display “180° turned” views of any projection recorded as well, providing completely new fluoroscopic views at the heart. 3 is one of just a few women active in the field of interventional electrophysiology. Her training includes periods under the tutelage of Prof. Dr. Michel Haissaguerre at the University Hospital in Bordeaux, one of the leading specialists in the field. Dr. Deisenhofer heads the Department of Electrophysiology at the German Heart Center Munich. There, 1,200 catheter ablations are performed in adults and 140 in children each year. The Munich Heart Center’s consolidated approach is one of its particular strengths, with all age groups and cardiac diseases treated under one roof. Said Dr. Deisenhofer: “Many patients present with complex arrhythmias and complex comorbidities. Tomorrow we will ablate an 86-year-old patient with recurrent ventricular tachycardia despite medical therapy who was rejected by another institution.” Dr. Deisenhofer has performed 40 ablations using CartoUnivu™ Module in the past six weeks. Plaything or Added-Value Product Is the software simply a fancy gimmick, or does it deliver genuine added value? “Added value is certainly discernible,” said Dr. Deisenhofer. “Exposure times are reduced significantly. Although all you do is display an additional fixed image and quickly forget that the fluoro image may have been generated a while back and is no longer up to date, the integration with the Carto® map creates the illusion of a real-time image. Together with other information like the ECG, which is derived directly from the heart, you gain confidence and are less tempted to step on fluoro in order to assure yourself of the catheter’s current position,” Dr. Deisenhofer continued. “I always scrutinize innovations extremely carefully. But this software really is very useful.” Both C-arm and magnetic field must be registered in order to allow the fluoro images to be integrated into the Carto® 3 System map. Dr. Deisenhofer does this after the transseptal puncture, subsequently transferring and saving four acquisition projections in CartoUnivu™ Module namely: AP, LAO 45°, RAO 45°, and left lateral. She uses only these projections during the remainder of the intervention. The new software turns the images as desired, transforming an AP projection into a PA projection, for example. It can also juxtapose two radiographic planes, as in a biplane view or it can make the electroanatomical map of the heart appear transparent against the background of the fluoro image. “You learn to rely on these integrated views quite intuitively, using them almost incidentally, like power steering,” commented Dr. Deisenhofer. “With the new software, you maneuver your way through the heart more easily and safely, only realizing later on that this new-found security is due to the integration of both views,” said the electrophysiologist. “I am convinced that users won’t wish to forego its benefits once they’ve grown accustomed to it.” 3 CartoUnivu™ Module Cardiology AXIOM Innovations | December 2013 | www.siemens.com/angiography  49
