The CardioMEMS System consists of a small pressure-sensing device that is implanted directly into your pulmonary artery during a minimally invasive procedure. Once implanted, the sensor measures and transmits your blood flow pressure and heart rate. A special electronic receiving unit allows patients to transmit pressure data from their homes to their provider. This data allows members of your heart failure care team to closely monitor any changes in your condition. By identifying changes early, before symptoms such as shortness of breath or weight gain occur, adjustments can be made to your medications and treatment plan to more effectively manage your heart failure.
