Queen of the Valley Medical Center among first hospitals in the North Bay to offer new FDA-approved implantable device to treat sudden cardiac arres


(Napa, Calif. – December 17, 2015) Queen of the Valley Medical Center is now offering patients the first implantable cardioverter defibrillator (ICD) system approved for use with magnetic resonance imaging (MRI) scans.

Sergio Manubens, MD, board-certified interventional cardiologist and director of the Cardiac Catheterization Laboratories at Queen of the Valley, was the first in Napa and Solano counties to implant the new device in a patient. “This is an important advancement for patients who rely on ICDs to detect irregular heartbeats and deliver life-saving therapy to restore a normal rhythm,” said Dr. Manubens. “Until now, these patients could not receive MRI scans on any part of their body.”

Dr. Manubens explained that older ICDs heat up when placed in a magnetic field and this in turn causes the heart muscle to heat up which can result in problems for the patient. The MRI restrictions of standard ICDs have resulted in a critical unmet need as data have shown that, within four years, more than one-third of patients with ICDs are likely to need an MRI, according to Medtronic, the maker of the new device.

Jeanette Mahoney, 58, a life-long Napa resident, was the first patient at Queen of the Valley Medical Center to receive the new device, after suffering a heart attack at her home in Napa.

An ICD is a small implantable heart device that is placed under the skin typically just below the collarbone on the left side of the chest. They are designed to continuously monitor heart rate and deliver an electrical signal to correct a life-threatening heart rate, if detected. MRI is an imaging test used regularly for a wide range of diagnoses including conditions such as stroke, cancer, Alzheimer’s disease, and muscle, bone and back pain, all which are prevalent among older adults.

On September 14, 2015, the U.S. Food and Drug Administration (FDA) approved the Evera MRI™ SureScan® ICD System from Medtronic for MRI scans on any part of the body. The system includes design enhancements from previous generation devices that allow it to safely undergo full-body MRIs, while maintaining the same longevity, proven shock reduction and physical size and shape of the original Evera ICD. The device is paired with the Sprint Quattro® Secure MRI SureScan® DF4 leads, backed by more than 10 years of proven performance with active monitoring, now tested for safe use during an MRI.

Queen of the Valley, a recognized leader in heart care and home to the area’s only Level III Trauma Center, is currently acquiring a new, multifunctional cardiac catheterization lab and a nuclear medicine imaging platform that will further increase the hospital’s ability to conduct minimally invasive procedures and treat a wide range of clinical problems including coronary artery disease — a leading cause of heart disorders in the U.S. For more information, visit
