About Pulmonary Artery Pressure Monitoring

What is Pulmonary Artery (PA) Pressure?

Each time blood passes through your heart, the right ventricle of your heart (the chambers on the lower right side) pump blood to your lungs through a large blood vessel. That large blood vessel is the pulmonary artery.

The blood pressure of your pulmonary artery reflects the amount of force your heart is exerting to pump blood from your heart to your lungs. If your heart has to work harder to pump that blood, then your pulmonary artery (PA) pressure goes up.

What is Pulmonary Artery Pressure Monitoring?

A Swan Ganz™ catheter (also known as a PA catheter) has been used for more than 30 years to monitor heart and lung function but is not designed for permanent monitoring of heart failure.

Modern cardiac monitors, sometimes referred to as pulmonary artery (PA) pressure monitoring devices, such as the CardioMEMS HF System, includes a permanent pressure-sensing device that can track and analyze the pressure in your pulmonary artery remotely from the comfort of your own home.

CardioMEMS How it Works

The CardioMEMS HF System is:

  • A small, implantable wireless sensor and remote heart failure monitoring platform
  • Designed specifically for the remote pulmonary artery pressure monitoring and management of congestive heart failure
  • Fastest growing, clinically proven, remote PA pressure monitor that significantly reduces heart failure hospital admissions and improves quality of life.1

What does Pulmonary Artery Pressure Tell Doctors About Heart Failure Progression?

Changes in pulmonary artery pressure measurements are an early indicator of worsening heart failure. If doctors can see these early changes, they can potentially make simple adjustments to your care that will help with heart failure management. These adjustments might include changes to medications and/or lifestyle.

Other signs of worsening heart failure can appear too late to prevent hospitalization or other larger adjustments to care, which is why pulmonary artery pressure monitoring can be a beneficial treatment option.
