On Jan. 9, 2015, Rodney Horton, M.D., a cardiac electrophysiologist at the Texas Cardiac Arrhythmia Institute (TCAI) at St. David’s Medical Center, performed a live case during which he completed a complex cardiac ablation without the use of fluoroscopy (or radiation). The procedure, which was showcased for the first time during the 20th international AF Symposium in Orlando, Florida, gained significant interest, as limiting radiation exposure to patients and medical staff is of increasing importance.

Physicians and researchers at TCAI pioneered this approach by combining existing mapping technology with the unique advantages of an energy-assisted transseptal needle to perform an entire complex ablation procedure without the need for fluoroscopic visualization. This more fully utilized the commercially available technology, along with some connection modifications to achieve greater performance.

As a result of this novel approach, manufacturers worked with TCAI to develop an FDA-approved device to allow other physicians to accomplish what some TCAI physicians have already been doing for more than a year.
