Advanced technology and clinical expertise have completely eliminated X-ray radiation exposure for some patients during certain catheter ablation procedures to correct heart arrhythmias at Medical City Fort Worth of Fort Worth.

The ability to eliminate the use of fluoroscopy, a type of X-ray, during an ablation can prevent a patient from being exposed to radiation equivalent to up to 100 chest X-rays, according to cardiac electrophysiologist Senthil Thambidorai, MD, who practices at Medical City Fort Worth.

Fluoroscopy was traditionally used during the procedure to help the physician guide a catheter to the precise location inside a patient’s heart to perform the ablation, during which heat or cold is applied to the tissue to correct the arrhythmia.

With the use of ultrasound and new three dimensional electroanatomical mapping systems, the amount of fluoroscopy needed for ablations has been greatly reduced over the past several years. The team at Medical City Fort Worth has taken the next step to perform some of these procedures using only ultrasound and 3D mapping – without fluoroscopy, eliminating X-ray exposure for the patient, as well as for the physician and the rest of the electrophysiology clinical team.

“We can now perform even complicated cases safely, with zero fluoroscopy, without compromising the effectiveness of the procedures,” Dr. Thambidorai said. “The key to this is the experience and expertise of our staff working at Medical City Fort Worth.”
