The CardioMEMS™ HF-System. The CardioMEMS pulmonary artery (PA) pressure sensor is shown (top, left), with its placement in the left PA. The sensor has a vertical orientation if the patient sits upright. After implantation, while still in hospital, the patient is instructed by trained staff how to position him/herself on the pillow that contains the measurement unit and measure and transmit the PA pressures once daily. The transmitted values can be accessed via a safe website by the heart failure nurse. Individual PA measurements (with tracings, see bottom right) and PA trends over time are visualized on the dashboard, allowing to interpret values in the context of supplementary information
