Highly detailed 3-D map of the heart
created with EnSite Precision
Abbott has announced that its EnSite Precision cardiac mapping system and Advisor FL Circular Mapping Catheter Sensor-Enabled are available for sale in the U.S.
The company expects the cardiac mapping system to soon become a new standard for treating patients with arrhythmia.
Dr. John Day, electrophysiologist at Intermountain Heart Institute in Salt Lake City, was the first to commercially use EnSite Precision during ablation procedures. Since then, sites in 12 states across the nation have used the system.

With EnSite Precision, physicians can map heart chambers with any electrophysiology catheter and customize procedures to address the uniqueness of each case. The mapping system in combination with the sensor-enabled tools allows catheter navigation to occur with only minimal fluoroscopy.
During catheter ablation procedures, physicians insert catheters into the heart, which record electrical information and display it in a 3-D anatomical model, so the abnormal rhythm can be evaluated. Then another catheter is used for ablation.
A small area of heart tissue under the tip of the ablation catheter is heated by radiofrequency energy to create a small scar, so the tissue can no longer sustain the arrhythmia. Cardiac mapping gives physicians a view of the inside of the heart so they can ablate more precisely.
EnSite Precision is built on a foundation of the St. Jude Medical cardiac mapping technology that’s used in over 2,000 electrophysiology labs worldwide. It includes a new solution called the EnSite AutoMap Module, which allows the electrophysiologist to identify the source of the irregular beat faster.
The module has a feature called TurboMap, which allows the physician to build a map of the heart using recorded data 10 times faster than current systems.
"This next-generation technology was designed in collaboration with some of the world's leading electrophysiologists so that they can quickly and precisely identify the source and substrate source of a patient's irregular heartbeat," Dr. Srijoy Mahapatra, medical director and vice president of medical affairs for Abbott's electrophysiology business, said in a statement.
