Cardiac Mapping Tools

A new segmentation tool for use during electrophysiologic (EP) procedures and a computer-based system to facilitate procedures to treat irregular heartbeats have been developed to enhance speed and flexibility of visualization and navigation during EP procedures.

"The introduction of EnSite system version 5.1 is a significant advance in 3D [three-dimensional] navigation and visualization technology,” said Jane J. Song, president of the St. Jude Medical atrial fibrillation division (St. Paul, MN, USA). "Combined with the EnSite Verismo segmentation tool, this upgrade will provide greater clinical value for physicians through increased speed, flexibility, and control during procedures. These capabilities are a crucial part of effective EP procedures.”

The EnSite 5.1 software features MultiPoint technology, which is designed to increase the speed and efficiency of cardiac mapping procedures. The EnSite Verismo segmentation tool uses computed tomography (CT) and magnetic resonance imaging (MRI) scans to construct 3D cardiac models that assist in procedure planning, geometry creation, and validation of therapy delivery. The EnSite system was included in St. Jude Medical's acquisition of Endocardial Solutions, Inc. (ESI; St. Paul, MN, USA) in January 2005.

Using the EnSite system, electrophysiology clinicians can create 3D models of their patients' cardiac anatomy during EP procedures and navigate the catheters used in those procedures. The system then collects and organizes activation and voltage data from the inner surface of the heart, allowing physicians to visualize arrhythmias on the 3D model and determine a treatment strategy.
