Cardiac Resynchronization Therapy (CRT) Guided by 3D Mapping System

The use of an electroanatomic navigation system in Cardiac Resynchronization Therapy (CRT) implantation is an increasingly used approach in the field of electrophysiology. The possibility to minimize X-ray exposure both for patients and for physicians is not the only most attractive aspect. Indeed it is feasible, safe, and allows to obtain more detailed information during the coronary sinus lead placement, in terms of both 3D anatomy and ventricular activation time. This procedure can improve the pacing site choice optimization, making CRT implantation an electrophysiological procedure.
