How do I prepare for the CardioMEMS HF System?

Your care team will discuss any changes you will need to make to your medications and daily routine.

Before the implant, you will be trained on how to take daily pressure readings.

What happens during the procedure?

The CardioMEMS™ PA Sensor is inserted into the pulmonary artery during a right heart catheterization.

  1. You may receive mild sedation to keep you comfortable.
  2. Your doctor will make a small incision and place the catheter into a vein in your neck or groin.
  3. Using an X-ray as a guide, your doctor will insert the catheter to your heart and into your pulmonary artery.
  4. Once the catheter is in the correct position, the sensor is released into the artery, where it remains permanently.
  5. The procedure will take an average of 30-45 minutes and most patients will go home the same day.

As with any medical procedure, there are risks associated with implanting the device, although complications are very rare.1

After the procedure, you may have mild pain or bruising at the incision site for a couple of days, but you should be able to resume normal activities soon afterwards.

  • You will not feel the sensor in your pulmonay artery
  • Since the sensor doesn't contain any batteries, it won't need to be replaced and won't need to be charged.
  • Your sensor won't interfere with daily activities or other implanted devices like pacemakers or defibrillators.

Implantation of the CardioMEMS PA Sensor is a safe, proven, common procedure.

Summary

Summary Checkmark

• Insertion of the CardioMEMS PA Sensor is a safe, proven, and commonly performed procedure.
