Optimization of Device Programming for Cardiac Resynchronization Therapy
Key result
Echo-guided BiV pacing optimization targets the ~30% non-response rate in heart failure patients.
Why the study?
Approximately 20-30% of patients with heart failure do not respond to cardiac resynchronization therapy, potentially due to suboptimal device programming.
Population
Selected patients with heart failure receiving cardiac resynchronization therapy
Comparison
Optimization of AV and VV intervals vs standard device programming

Implication
Should not yet change CRT programming practice; leaves open efficacy of echocardiography-guided optimization in trials.

Intervention
Optimization of device programming (atrioventricular and interventricular intervals)
Optimization of AV and VV intervals using techniques like echocardiography is reviewed as a strategy to address the 20-30% non-response rate in CRT.
Cite This Study
Burri et al. (2006) conducted a review in Heart failure. Optimization of device programming for biventricular pacing was evaluated. Optimization of device programming for biventricular pacing, particularly using echocardiography, is reviewed to address the 20-30% non-response rate in heart failure patients.
