Descripción detallada
Accent Cardiac MRI study was a prospective, randomized ,multi-center study conducted in Asia. Subjects indicated for dual-chamber pacemaker and who signed study consent form were considered enrolled and post implant were randomized to either Cardiac MRI Scan Group or Control Group.
Clinical evaluation and device interrogation were performed at baseline, pre- and post-MRI scan, and one month post-MRI for all subjects. At 9-12 weeks post-implant, patients in Cardiac MRI Scan Group underwent an elective non-diagnostic cardiac MRI scan at 1.5 Tesla (T) while patients in Control group underwent device interrogation and clinical evaluation twice with a 45-minute waiting period in between. The safety endpoint was freedom from MRI-related complications while efficacy endpoint was change in right atrial/ ventricular (RA/RV) capture threshold and sensing amplitude from pre-MRI scan to one month post-MRI scan.
