Name of Research Trial: CHAMPION:
CardioMEMS® Heart Sensor Allows Monitoring of Pressure to Improve Outcomes in NYHA Class III Heart Failure Patients (Protocol CM-06-04)

Principal Investigator: John B. O'Connell, MD

IRB Project Number: STU00001613

Description of Research Trial:
This research study is looking for patients who have been diagnosed with heart failure (HF). Heart failure is a disorder that causes damage to the heart over a period of time. This damage makes it difficult for the heart to pump enough blood to meet the demands of the body. Heart failure is a progressive disease that often gets worse over time.

The purpose of this study is to evaluate an investigational system developed for use in the medical management (helping your doctor decide what medications are best) of patients suffering from heart failure, the CardioMEMS® HF Pressure Measurement System. The study measurement system is not approved by the U.S. Food and Drug Administration (FDA) for treatment of patients with decreased heart function; therefore, its use in this study is considered experimental.

The study measurement system consists of a sensor, delivery system, external electronics (antenna), and a home monitoring unit. The system will be used in your home to transmit your pulmonary artery pressure measurements to a secure website for your physician to review and determine the best way to manage your disease based on the information provided by the study measurement system. The study sensor will be implanted during a heart catheterization procedure and is placed inside your pulmonary artery (one of the vessels close to the heart) with a special catheter.

Participation in this study will last approximately 3 years and will involve about 10 visits.
