CardioMEMS: The Future of Heart Failure Monitoring

Is CardioMEMS Right for You?

Contact the Saint Mary's Congestive Heart Failure Program (known as the PUMP Club) at 203-709-PUMP (7867) for an appointment.

At Saint Mary's, we want to help you monitor and manage your congestive heart failure (CHF) from the comfort of your own home.

We're one of the first hospitals in the nation to offer the CardioMEMS Heart Failure System, the first and only FDA-approved heart failure monitoring device that has been proven to significantly reduce hospital admissions when used by doctors to manage heart failure.

Who Is a Candidate for CardioMEMS?

If you have NYHA Class III heart failure, CardioMEMS could be an option for you. Roughly 1.4 million patients in the U.S. have this type of heart failure, and historically these patients account for nearly half of all heart failure hospitalizations.

How It Works

CardioMEMS deviceThe CardioMEMS HF System features a sensor that is implanted in the pulmonary artery (PA) during a non-surgical procedure to directly measure PA pressure, an important marker that can predict changes in your condition sooner than monitoring your weight or blood pressure.

With CardioMEMS, you can painlessly and quickly transmit daily sensor readings to your doctor from the comfort of home using a special sensor-equipped pillow.

The CardioMEMS sensor is designed to last a lifetime, and doesn’t require batteries. Once implanted, the wireless sensor sends pressure readings to an external patient electronic system when you lie on the special sensor pillow. You'll feel no pain, or any other sensation, during the readings, which take just minutes.

Sending data to your doctor with CardioMEMS allows him or her to detect worsening heart failure sooner and adjust your treatment accordingly. This fast response helps reduce the likelihood that you will need to be hospitalized for heart failure treatment.

What Our Patients and Physicians Are Saying

Pat Hunihan

Pat Hunihan, 75, of Waterbury recently was treated for heart failure at Saint Mary’s and was the first patient to benefit from the CardioMEMS HF System. “I think it’s great. It’s telling my doctor about all the fluid that I’m building up and that’s what they’re trying to get rid of—the fluid. Then maybe my heart won’t have to work as hard,” said Hunihan, whose cardiologist, Dr. Paul Kelly, recommended CardioMEMS.

A few years ago, Hunihan was hospitalized for heart failure treatment and subsequently discharged to a skilled nursing facility for physical therapy before she was able to return home. “I had gotten to the point where I was gaining a lot of weight. I had a lot of swelling in my feet and my legs. I couldn’t walk.”

She hopes to avoid repeating that experience and thinks the CardioMEMS HF System is a wonderful idea. The system is easy for her to use at home. “I love it,” she said. “It talks to me. It tells me, ‘Lay straight. Don’t move. OK, you can get up now.’”

Dr. Paul Kelly, Chief of Cardiology at Saint Mary's Hospital

“Saint Mary’s Hospital is committed to improving patient care and investing in innovative medical technology such as the CardioMEMS HF System,” said Dr. Kelly, Chief of Cardiology and Medical Director of Cardiac Services at Saint Mary’s. “The hospital is always pursuing new and innovative solutions that result in successful patient outcomes in the diagnosis or treatment of heart failure.”

Dr. Rebecca Scandrett, Interventional Cardiologist at Saint Mary's Hospital

“CardioMEMS is revolutionary in the treatment of heart failure patients, who are among the sickest patients we see and can often be the most challenging to treat,” said Dr. Rebecca Scandrett, an interventional cardiologist with Saint Mary’s and Franklin Medical Group, who performed the hospital’s first procedure in October of 2015. “CardioMEMS gives us another tool to help guide their therapy. It helps to improve their quality of life, extend their life, and keep them out of the hospital.”
