Arjun Gururaj, MD, Nevada Heart and Vascular Center and the Medical Director for the Electrophysiology Lab at Desert Springs Hospital Medical Center, was the first electrophysiologist in Nevada to utilize the EnSite™ X EP System with EnSite Omnipolar Technology (OT), a new cardiac mapping platform available in the U.S. and across Europe that is designed to help physicians improve upon the treatment of heart arrhythmias, otherwise known as abnormal heart rhythms. The inaugural procedure was performed on January 3, 2022, at Desert Springs Hospital.
To better pinpoint the location where arrhythmias occur and need to be treated by ablation, the cardiac mapping system creates a very detailed 360-degree, three-dimensional map of the heart that precisely maps approximately one million points in the heart. Additionally, it provides accurate electrograms, which are electrical recordings of the heart that use signals received from electrodes placed against the patient’s own heart tissue.
“We use this mapping technology to perform cardiac ablations, which is when we scar specific areas of tissue within the heart to block abnormal electrical signals,” explained Dr. Gururaj, who has performed cardiac ablations for more than 20 years. “Having such a precise and accurate map of the heart helps ensure we are only scarring what is absolutely necessary. We want to keep as much heart tissue as possible while eliminating the arrhythmias because heart tissue helps move blood, oxygen and nutrients through the body.”
There are several different types of heart arrhythmias, defined by the location within the heart’s upper or lower chambers and if it is beating too fast or too slow. The three main categories include supraventricular arrhythmias, ventricular arrhythmias and bradyarrhythmias. One of the most common heart arrhythmias is atrial fibrillation, which is described as an irregular heartbeat that feels like a quivering heart, according to the American Heart/Stroke Association. If left untreated, arrhythmias can lead to complications such as stroke, heart failure, blood clots and sudden death.
“We’ve invested in this new cardiac mapping technology, along with physician and staff training, to ensure Southern Nevada residents and tourists have access to treatment options that can improve their quality of life and prevent related complications of heart arrhythmias and have access to the most advanced treatment options,” said Chris Loftus, CEO of Desert Springs Hospital. “We are very proud to partner with Dr. Gururaj on this advancement and we are already seeing incredible results.”
