The CardioMEMSTM heart failure (HF) system is an ambulatory pulmonary artery pressure monitoring system designed to help manage patients with difficult to control HF symptoms and to reduce the need for hospitalizations due to acute HF exacerbations. It is currently approved for use in patients with New York Heart Association class III symptoms and a previous hospitalization for congestive heart failure within the last year, regardless of ejection fraction.1,2 The entire system consists of a small pressure sensor (Figure 1) that is percutaneously placed in a branch pulmonary artery and can be remotely interrogated, in the hospital and at home, using a receiver.
Available evidence within the literature indicates that the device implant is a safe process with no major complications being reported.1–4 The implant procedure is simple and involves a pulling thread that secures the tightly bound sensor to the delivery catheter. Once pulled, the nitinol …
