Confirmation of cardiac radiofrequency ablation treatment using intra-procedure acoustic radiation force impulse imaging

Conference Paper

Recurrence of atrial fibrillation after transcatheter ablation (TCA) is common because there is no imaging modality that can visually confirm the presence of radiofrequency ablation (RFA) lesions. We have previously shown that acoustic radiation force impulse (ARFI) imaging can visualize the relative tissue stiffness changes caused by RFA. The objective of this study was to determine if intra-procedurally acquired ARFI images could identify RFA lesions. © 2012 IEEE.
