Contact force guided radiofrequency current application at developing myocardium.

Publication Type:Academic Journal

Source(s):Journal of cardiovascular electrophysiology [J Cardiovasc Electrophysiol] 2022 Aug; Vol. 33 (8), pp. 1757-1766. Date of Electronic Publication: 2022 May 28.

Abstract:Introduction: Catheter contact is a key determinant for lesion size in radiofrequency catheter ablation (RFA). Monitoring of contact force (CF) during RFA has been shown to improve efficacy of RFA in experimental settings as well as in adult patients. ...
