The Very Best for the Heart

The Axiom Artis dBC Magnetic Navigation by Siemens Medical Solutions is the worldwide first biplane cardiology system with digital flat detector (FD) technology for magnetic navigation of catheters and guidewires. For the first time, the system combines in both planes the advantages of magnetically-assisted intervention using the proven technology of flat detectors. On one hand, interventions are performed more quickly with this system, on the other, the catheter reaches anatomical regions that would be difficult to access without magnetic steering. Additional advantages are the excellent image quality provided by the flat detectors and the highly flexible design of the system. If the magnets are not required for an intervention, they are swiveled to the side. Key areas for system application are cardiac examinations for adults and children as well as electrophysiology.

The new system is based on two technologies where Siemens is the undisputed leader: FD technology and magnetic navigation. As the first manufacturer on the market, Siemens is offering the Axiom Artis dBC, a biplane FD system combined with magnetically-assisted navigation. Worldwide more than 100 biplane FD cardiology systems by Siemens are in use. And more than 30 Siemens systems with magnetic navigation help patients with indications that are either difficult to treat or not at all with standard catheter procedures.

Two computer-controlled permanent magnets by the American company, Stereotaxis, Inc. are used. Those two magnets especially developed for this system align the magnetic tip for the catheter and guidewires and allow a targeted control of the catheter. This offers a greater precision and flexibility than with previous catheter types. The resulting advantages are: The examination time can be reduced, thus, the patient receives lower dose and less contrast agent. The flexibility of the catheters also reduces the risk of complications to the patient. In addition, the range of applications is expanded, because the physician is able to navigate the catheter in anatomical regions that were either not accessible at all with conventional catheters, or if, then only under difficulties.

These advantages are complemented by the performance characteristics of the biplane system. The two flat detectors convert the data directly into digital images, minimizing data loss in the imaging chain. High resolution ensures detailed visibility of the finest vessel structures and stents, while dynamic density optimization further supports improved image quality. It harmonizes the distribution of grey scales in the image. For additional information, the cardiologist can use ultrasound, CT or MR images, since the multi-modality display for Axiom Artis dBC shows CT or MR images as well.

To provide for best possible radiation protection, Siemens developed C.A.R.E. (Combined Application to Reduce Exposure), a package that protects both patient and staff. In addition to technical configurations for reducing radiation exposure, for example automatic copper filtering which adjusts the filter settings to the density of the respective body region, pulsed fluoroscopy may be used as well for further dose reductions.

Axiom Artis dBC is highly compatible with Axiom Sensis, the Siemens recording system for hemodynamics and electrophysiology. The recording system can be conveniently operated under sterile conditions at the examination table.
Among the first facilities using the new Siemens system in clinical application is the Cleveland Clinic Foundation in Cleveland, Ohio, USA, and the Mother Frances Hospital in Tyler, Texas, USA.
