3 The procedure
3.1 Insertion of implantable pulmonary artery pressure monitors is usually done under local anaesthesia. Using a percutaneous approach, commonly via the femoral vein, a passive radiofrequency sensor without batteries or leads is implanted into a distal branch of the pulmonary artery, with radiological guidance. The sensor is anchored within the artery.
3.2 Data are downloaded in a secure format via an antenna linked to a computer in the patient's home. The antenna can be housed in a pillow on which the patient lies for this purpose. Data are then forwarded daily by the patient to a remote secure database from where the information can be accessed by the heart failure team.
