Registry of Patients With CardioMEMS

Eligible patients will undergo implantation of a pulmonary artery sensor (CardioMEMS), a wireless implantable hemodynamic monitoring system in the cardiac catheterization laboratory. This system has a passive wireless, radiofrequency sensor without batteries or leads. Patients transmit data through a device in their home that interacts wirelessly with the sensor. Clinicians retrieve this data via a web interface to use in making management decisions for patients.
