MEMS-Based Hemodynamic Monitoring for Advanced Heart Failure Management
Abstract
Heart Failure (HF) is a chronic disease where heart function worsens
over time resulting in symptoms of shortness of breath, fluid accumulation, and
frequent hospitalizations. CardioMEMS™ is a medical device designed to
measure Pulmonary Artery (PA) hemodynamics to guide medical therapy. The
MEMS-based wireless pressure sensors are permanently implanted using
minimally invasive catheters and transmit blood pressure and heart rate data to
an external electronics system. Device effectiveness was proven by a
randomized clinical trial, where guided therapy using CardioMEMS™ resulted in
a 33% reduction in HF hospitalizations during an 18 month follow-up. Future
challenges include making hemodynamic monitoring a medical standard of care
for advanced heart failure management.
