Direct Left Atrial Pressure Monitoring in Ambulatory Heart Failure Patients
Key result
A permanently implantable direct left atrial pressure monitoring system was feasible and accurate, with 87% of measurements within ±5 mm Hg of simultaneous wedge pressure at 12 weeks.
Why the study?
Is a permanently implantable direct left atrial pressure monitoring system feasible, safe, and accurate in ambulatory patients with chronic heart failure?

Implication
Implantable LAP monitoring is feasible in ambulatory HF; leaves open whether LAP-guided therapy improves outcomes.
Structured PICO
Is a permanently implantable direct left atrial pressure monitoring system feasible, safe, and accurate in ambulatory patients with chronic heart failure?
P
Population
8 ambulatory patients with chronic heart failure and a recent heart failure hospitalization or unplanned visit, followed for 12 weeks.
I
Intervention
Permanently implantable, direct left atrial pressure (LAP) monitoring system, with patients measuring LAP twice daily and receiving aspirin 150 mg and clopidogrel 75 mg daily
O
Outcome
Accuracy of device LAP measurements compared to simultaneous pulmonary capillary wedge pressure readings at 12 weekssurrogate
A novel permanently implantable direct left atrial pressure monitoring system is feasible, safe, and accurate compared to right heart catheterization at 12 weeks in ambulatory heart failure patients.
Cite This Study
Ritzema et al. (2007) studied chronic heart failure (n=8). Permanently implantable, direct left atrial pressure (LAP) monitoring system was evaluated on Device LAP measurements within +/-5 mm Hg of simultaneous pulmonary capillary wedge pressure readings. A permanently implantable direct left atrial pressure monitoring system was feasible and accurate, with 87% of measurements within ±5 mm Hg of simultaneous wedge pressure at 12 weeks.
