If you have heart failure, changes in the pressure of blood through your pulmonary artery (PA) can indicate worsening heart failure—even before you notice symptoms such as shortness of breath or weight gain. The CardioMEMS™ HF System features a small pressure-sensing device that is implanted directly into your pulmonary artery. The sensor measures pressures in your lungs that rise when fluid increases because the heart is too weak or stiff to pump effectively. With these pressure readings, your care team can then take steps to manage your heart failure before it has serious effects on your quality of life or puts you back in the hospital.

The CardioMEMS HF System is the first and only FDA-approved heart failure monitor proven to significantly reduce heart failure hospital admissions and improve quality of life; it has been clinically proven to reduce hospital admissions by 58% over an average of 12 months.

  • The CardioMEMS HF System is indicated for wirelessly measuring and monitoring pulmonary artery (PA) pressure and heart rate in New York Heart Association (NYHA) Class III heart failure patients who have been hospitalized for heart failure in the previous year; the hemodynamic data are used by physicians for heart failure management and with the goal of reducing heart failure hospitalizations.

Benefits of the CardioMEMS™ HF System include:

  • Your doctor can use the sensor information to make changes to your treatment before you feel symptoms.
  • It is simple and easy to use, with a home electronics unit that wirelessly sends data to your doctor.
  • The sensor does not need a battery or replaceable parts.

How the CardioMEMS™ HF System Works

The CardioMEMS™ HF system measures your pulmonary artery pressure and heart rate through a sensor that is implanted in your pulmonary artery (the blood vessel that moves blood from your heart to your lungs). Once the device is implanted, you take daily pressure readings from the comfort of your home and wirelessly transmit the data to your doctor for continuous monitoring.

The sensor is small and does not require any batteries or wires. You will not feel it, and it will not interfere with your daily activities or other implanted devices such as a pacemaker or defibrillator.

The system includes an electronics unit that you use to take the daily measurements. This is a simple process that takes only a few minutes. There is no pain or sensation during the readings.
