Quantitative evaluation of atrial radio frequency ablation using intracardiac shear‐wave elastography

Purpose: Radio frequency catheter ablation (RFCA) is a well‐established clinical procedure for the treatment of atrial fibrillation (AF) but suffers from a low single‐procedure success rate. Recurrence of AF is most likely attributable to discontinuous or nontransmural ablation lesions. Yet, despite...
