1. A method of monitoring congestive heart failure in a patient, the method comprising:
- providing a pressure sensor secured to a proximal anchor and a distal anchor;
delivering the pressure sensor to a hole in an atrial septum of the patient'"'"'s heart;
deploying the pressure sensor with the proximal anchor on a proximal side of the septum, and the distal anchor on a distal side of the septum; and
monitoring a fluid pressure in the left atrium of the patient'"'"'s heart.
