SAN FRANCISCO — In this video, Vivek Y. Reddy, MD, director of electrophysiology at Mount Sinai Medical Center, discusses the SMART-AF trial, presented at the Heart Rhythm Society Annual Scientific Sessions.

The trial assessed AF ablation using the SmartTouch catheter (Biosense Webster), which includes a contact force sensor to determine when contact with tissue is made and the degree of force being applied. Prior data has indicated that the amount of force is relevant for the size and quality of ablation lesions; the results from SMART-AF indicated a significant improvement in success rate among operators able to maintain optimal force during the procedure compared with those that did not.

Reddy said that these results have important implications for the future, and suggested that the ability to determine the presence and force of tissue contact may "usher in a new era of AF ablation."
