Visia AF MRI™SureScan™and Visia AF™ICDs

The Medtronic Visia AF MRI™ SureScan™and Visia AF™implantable cardioverter defibrillators (ICDs)are single-chamberICDs that can detect atrial fibrillation (AF), while also treating life threatening rhythms in the lower chambers of the heart.The Visia AF ICDs include a proprietary algorithm that accurately detects AF episodes, captures AF burden frequency and duration[1], and alerts the physician from the patient’s home, enabling physicians to manage patients at increased risk for stroke and heart failure.

The ability to detect and monitor new onset, asymptomatic, and previously undiagnosed AF has not been possible in traditional single-chamber ICDs until now. When paired with the Sprint Quattro Secure MRI™ SureScan™ DF4 leads, the Visia AF MRI SureScan device also allows patients to undergo full-body MRI scans.

The Visia AF MRI SureScan and Visia AF ICDs received FDA approval in 2016 and CE Mark in 2015.

Specific Device Features

  • Paired with Sprint Quattro® Leads: The system utilizes the industry standard Sprint Quattro® single and dual coil leads, with more than 11 years of proven performance with active monitoring2. The Sprint Quattro Secure MRI™ SureScan™ DF4 leads have been demonstratedsafe for use in an MRI environment3.
  • SmartShock™ 2.0 Technology: Exclusive, industry-leading shock reduction algorithm that enables the devices to better differentiate between dangerous and harmless heart rhythms4.
  • PhysioCurve® Design: A contoured shape with thin, smooth edges that increases patient comfort by reducing skin pressure by 30 percent5.
  • Industry-Leading Projected Longevity6 and Warranty7: Battery longevity of 11 years, and a 10-year warranty.

Importance of Atrial Fibrillation Detection

  • An estimated 3 million people in the United States have AF8.
  • AF is a condition that involves an irregular quivering or rapid heart rhythm in the upper chambers (atria) of the heart, and patients with AF are five times more likely to have a stroke9and three times more likely to have heart failure10.
  • Approximately 20 percent of patients with single chamber ICDs who experience ventricular arrhythmias (irregular heart rhythms in the lower chambers) may develop AFin the first two years after their device implant11, which often goes undetected with traditional external monitors12-13.
  • Early detection of AF can help physicians better tailor treatment to the needs of the patient.
