CardioMEMS HF System

Heart failure occurs when the heart is unable to pump enough blood to meet the body’s demands. According to the Centers for Disease Control and Prevention, more than 5.1 million Americans have heart failure, with 670,000 new cases diagnosed each year. Patients with heart failure are frequently hospitalized, have a reduced quality of life and face a higher risk of death.

The CardioMEMS HF System is the first and only FDA-approved heart failure monitoring device that has been proven to significantly reduce hospital admissions when used by physicians to manage heart failure.

The CardioMEMS HF System features a sensor that is implanted in the pulmonary artery (PA) during a non-surgical procedure to directly measure PA pressure. Increased PA pressures appear before weight and blood pressure changes, which are often used as indirect measures of worsening heart failure. The new system allows patients to transmit daily sensor readings from their homes to their health care providers allowing for personalized and proactive management to reduce the likelihood of hospitalization.

Quick Facts

  • Uses a miniaturized, wireless monitoring sensor that is implanted in the pulmonary artery
  • Features a wireless sensor powered by radio frequency energy that does not require batteries
  • Implanted during a minimally invasive, catheter-based procedure
  • Completely sealed capsule that uses microelectromechanical systems
    (MEMS) technology
  • Patients use a portable electronic unit and a special pillow containing an antenna to take daily sensor readings with the CardioMEMS HF System — a simple process that takes only a few minutes.
