Salinas Valley Memorial Completes Successful Implant of MRI-Safe Pacemaker

SVMHS only west coast hospital chosen for clinical research trial

SALINAS, CA, July 26, 2011 At 8:30 A.M. today, Salinas Valley Memorial Healthcare System launched its clinical participation in a national research trial for the Medtronic SureScanTM-Advisa MRITM pacing system when Taylor Liu, MD, implanted the device in two patients. In the past, people who have an implanted pacemaker could not safely undergo a MRI (magnetic resonance imaging) scan that might be needed to diagnose other critical health problems. It is estimated that 50 to 75 percent of patients with an implantable cardiac device will need a MRI scan over the lifetime of the device.*

There are only fifteen sites in the country involved in this clinical trial, and SVMHS is the only one on the west coast to be selected by Medtronic for this study. "I think that is a reflection of the caliber of the cardiology, imaging and research programs that have been a major focus of this hospital," says the trial's principal investigator Timothy Albert, MD, cardiologist and medical director of Salinas Valley Memorial's Cardiovascular Diagnostic Center.

Pacemakers have complex electronic circuitry and contain some metal. Exposure to the powerful magnets in a MRI may put tension on the system, cause heating or disrupt the electronics. SVMHS completed a successful research trial for the REVO Pacemaker, the first generation of MRI-safe pacemakers. The REVO came with limitations on the area of the bodythat could undergo a MRI. "The breakthrough SureScan-Advisa MRI pacemaker does not have these limitations," says Dr. Albert. "This research study is designed to open doors to being able to do all sorts of imaging on patients with neurologic issues such as a stroke or orthopedic treatments such as a joint replacement. "

Through the Carelink® Network, the implanted SureScan-Advisa automatically transmits comprehensive threshold measurements and adjustments, and other diagnostic data to cardiologist's office. It includes features that enable it to diagnose and manage other problems that may develop in the patient in the future.

Salinas Valley Memorial's dedication to research is one part of a full continuum of care in the Harden Memorial Heart Program. Established more than 20 years ago, the program includes a range of services including the Stanford Cardiac Surgery Program at Salinas Valley Memorial Hospital, and the Cardiovascular Diagnostic Center at Ryan Ranch.
