Brief Summary:
The purpose of this observational study is the assessment (safety and efficacy) of the St. Jude Medical Tendril MRI™ leads. The Tendril MRI™ leads are a full part of the Accent MRI™ System, consisting of Tendril MRI™ leads and Accent MRI™ pacemaker. The subject population includes patients with a standard bradycardia pacing indication.
Detailed Description:
Magnetic resonance imaging (MRI) is a diagnostic method to view high quality two and three dimensional images of the body. However, magnetic resonance imaging systems generate three electromagnetic fields that are used to produce an image. These include a static magnetic field, a time varying gradient magnetic field, and a radiofrequency field. All three of these fields interact with implanted devices and could create hazards for the device, the patient, or both. Due to these issues, currently marketed pacemaker systems may be contraindicated for use in an MRI environment.
St. Jude Medical has developed a system, the Accent MRI™ system, comprised of the Accent MRI™ device and the Tendril MRI™ lead, and an investigational MRI Activator™, designed to mitigate such interactions.
