CardioMEMS™ – a New Option for Monitoring Heart Failure

CardioMEMSDirectly measuring pulmonary artery pressure (PA) pressure via a procedure called a right-heart catheterization is a standard practice for managing worsening heart failure in patients who have been hospitalized. Since heart failure is a chronic disease, most patients do not remain in the hospital for extended periods of time. The new CardioMEMS™ Heart Failure System offers many advantages for monitoring patients outside the hospital.

How does the CardioMEMS™ technology work?

  • Until now, patients often had to be hospitalized so their condition could be monitored.  Otherwise, worsening heart failure could only be detected by checking daily signs such as changes in weight or blood pressure.
  • The CardioMEMS™ Heart Failure System is a miniature, wireless monitoring sensor that is implanted in the pulmonary artery in a non-surgical procedure.
  • The device measures pressures inside the heart, which is important in the management of heart failure because pulmonary artery pressure changes weeks before patients begin to experience signs or symptoms their conditions are deteriorating.
  • Simply by lying on a special pillow and pressing a button, patients can take daily sensor readings at home, and transmit the data to their healthcare providers via a secure, online portal.
  • By detecting changes in pulmonary artery pressure prior to the onset of symptoms, your clinician can proactively manage medications and other treatment options.
  • The implantable sensor (about the size of a paperclip) is a completely sealed capsule that uses microelectromechanical systems (MEMS) technology, which allows the creation of sensors with measurement stability and energy efficiency.
  • It is designed to last the lifetime of the patient and does not require leads or batteries. 
  • All of the sensor components are made of materials that have been chosen for their durability, robustness, biocompatibility, and insensitivity to changes in body chemistry or biology.
  • The sensor is powered by radio frequency (RF) energy.
  • Data from a clinical trial showed the CardioMEMS technology reduces heart failure hospital admissions by up to 37 percent.
