(HealthDay News) – In patients requiring cardiac resynchronization therapy (CRT), implanting a CRT device via a sensor-based tracking system is safe and effective and requires much less fluoroscopy time, according to a study published online Sept. 3 in Circulation: Arrhythmia and Electrophysiology.

Sergio Richter, MD, from the University of Leipzig in Germany, and colleagues used a sensor-based electromagnetic tracking system (MediGuide from St. Jude Medical) to implant a CRT device with a lateral or posterolateral left ventricle lead position in 15 adult patients with severe heart failure requiring CRT. Patients were also implanted with right atrial and right ventricular leads using conventional fluoroscopy.

Using the new tracking system, the researchers found that the total mean procedure time was 116 minutes, the median total fluoroscopy time was 5.2 minutes, and the median fluoroscopy time for left ventricle lead deployment was 2.6 minutes. There were no complications that were sufficiently severe to require an acute intervention or re-operation. The mean total fluoroscopy time using conventional fluoroscopy is 22 minutes, according to the authors.

“Use of the MediGuide tracking technology allows for safe and successful CRT implantation with the potential for reduced fluoroscopy time,” Richter and colleagues conclude.

Several authors disclosed financial ties to Biotronik, Medtronic, and Biosense Webster.
