PMC among first in KY to receive new heart mapping technology

Pikeville Medical Center (PMC) Heart Institute is one of the first hospitals in Kentucky to receive new technology for mapping electrical systems in the heart.


The software, called EnSite Precision, is in its early phase and is available in only 25 centers across the country.


“This is truly the latest and greatest in the world of electrophysiology,” said PMC Electrophysiologist Chase Reynolds, MD.  


This system is used in ablation procedures for patients with arrhythmia (abnormal heart rhythms) and is designed to enable faster and more accurate maps of the heart.


The most common arrhythmia is atrial fibrillation (AFib).


“AFib affects about 6 to 7 million people in the US at the present time and that number is expected to grow to 15 million by about 2030,” said PMC Electrophysiologist Michael Antimisiaris, MD.


Dr. Reynolds said, “This new system is a tool that improves our ability to reach our goal and improve the outcomes for our patients who undergo ablation procedures.”


PMC electrophysiologists say their goal is to bring a patient, who has an abnormal heart rhythm, to the electrophysiology lab and when they leave the lab they will have gone through a procedure that prevents that rhythm from occurring at any point in the future.


“Certainly everybody would want this new technology but it could not be released to the whole US or the whole world at the same time,” said Dr. Antimisiaris. “They selected a group of hospitals that could produce good results during the initial trials. When they offered it to us, obviously, we accepted it without hesitation.”


Dr. Antimisiaris says the procedure uses electrical signals from inside the heart to help identify where the tips of the catheter and other electrodes are located along with a magnetic component that constructs the geometry of the heart in three dimension.


“This process gives us a 0.2 mm accuracy,” said Dr. Antimisiaris. “We are talking about the kind of accuracy that gives us a ten-fold improvement.”


“The precision is unbelievable,” said Dr. Reynolds. “Before, when we would map these arrhythmias, we were limited to one or two reference points that we could record at the same time. Now, with this new system, there is not realistically a limit to the number of data points we can obtain.  With one extra beat we can do multi-point mapping, which means obtaining electrical activity from every single catheter that is in the heart at that time.”


The expected results from the Precision System should improve the accuracy of the procedure as well as reduce procedure time which is better and safer for the patient.
