Online Supplemental Movie 1: Acoustic radiation force impulse (ARFI) images (21 total) showing the dynamic elasticity changes in a myocardial sample during a 120 second (temperature controlled at 65°C) radiofrequency ablation (RFA). The plane of the ablation catheter is into the page. The color bar units are microns of ARFI-induced displacement, and the growing region of lower displacement indicates local stiffening due to the RF treatment.
