Presentation
History of coronary artery bypass grafting
Patient Data
Frontal chest radiograph shows an enlarged heart along with changes of coronary artery bypass grafting.
Magnified view centered on the right pulmonary vasculature demonstrates the Cardiomems device deployed in the right interlobar pulmonary artery.
Case Discussion
CardioMEMS™ HF System is an approved wireless heart failure (HF) monitor that is deployed in the central pulmonary arteries. This device remotely monitors changes in pulmonary artery (PA) pressure, an early indicator of the onset of worsening heart failure.
Two 10-mm-diameter polytetrafluoroethylene-coated nitinol loops maintain sensor apposition to the vessel wall following deployment.
Once the catheter is in the correctly positioned, the sensor is released into the artery, where it remains permanently.
