SIEMENS/BIOSENSE WEBSTER TO CREATE 3D HEART IMAGES.

Siemens Medical Solutions has signed an ongoing research and development agreement with Biosense Webster to create three- dimensional (3D) images of the heart as a diagnostic and interventional tool for electrophysiologists. The goal of combining the two companies' advanced technologies is to create accurate images that will serve as roadmaps for procedures used to identify and treat cardiac arrhythmias, thereby improving both treatment planning and outcomes.

"As doctors explore new ways to treat heart conditions with catheter-based procedures, they need clear and precise images of the heart to guide them," said Manfred Fink, vice president, Angiography and X-ray Division, Siemens Medical Solutions. "The combination of accurate cardiac images from Siemens' imaging systems with precise electroanatomical data from Biosense Webster's mapping systems will create unprecedented dimensional pictures to aid in the diagnosis and treatment of arrhythmias and other heart disorders."

To create these comprehensive images, the research team will combine real- time electroanatomical mapping data from Biosense Webster's CARTO(TM) XP EP Navigation and Ablation System with pre-procedural anatomical cardiac images provided by Siemens' magnetic resonance (MR) and computed tomography (CT) technologies. Electroanatomical mapping traces the movement of electrical signals through the heart. With the CARTO XP system, sensors located at the tip of specially designed catheters acquire data at various points within the heart to pinpoint the locations of irregular rhythms, or arrhythmias. Combining MR/CT images with electroanatomical mapping data produces a detailed 3D representation that shows the precise location of the erratic electrical signals in that patient's heart.

In the future, researchers will also use the AXIOM Artis dFC Magnetic Navigation System(TM) which integrates Siemens' most advanced digital fluoroscopic imaging system - the AXIOM Artis dFC (Flat Panel Detector System) - with the Niobe(R) Magnetic Navigation System from Stereotaxis Inc. This combination will allow direct magnetic steering of catheter- and guidewire- based devices along complex paths within the heart and coronary vasculature. Such integration of 3D images with remote steering is designed to make interventional procedures less cumbersome, faster and more accurate.

"This research agreement is just one part of our total solution of imaging and information technologies that address the challenges of today's increasingly busy EP labs," said Fink. "Siemens is committed to advancing this fast-growing medical field with a brave new world of diagnostic and therapeutic tools that enhance clinical and financial outcomes for our customers."
