Maximise global contractility. SmartDelay™ AV delay optimisation is fast and automatic, and recommends personalised sensed and paced AV delays to maximise each patient’s haemodynamic response to CRT without resorting to echocardiography.

Smart-AV Study

Overall results showed SmartDelay was non-inferior to fixed AV and Echo. Additionally, SmartDelay is automated and much faster than an Echo.

1014 patients evaluated at 3 and 6 months

Results: No difference in improvement in left ventricular end-systolic volume at 6 months was observed between the SmartDelay and echocardiography arms (P=0.52) or the SmartDelay and fixed arms (P=0.66).1

LV-Only Considerations

SmartDelay recommends the pacing chamber based on the patient’s intrinsic AV conduction, offering potential to avoid unnecessary RV pacing in patients with intact RBB conduction (“If it’s not broken, don’t fix it”).2

In the ESC Guidelines, there is agreement that LV pacing alone seems to be non-inferior to biventricular pacing.3

Data from four Boston Scientific Sponsored studies: two acute (PATH-CHF4 and CRTAVO5) and two chronic (DECREASE HF6-7 and RENEWAL 4 AVT8) studies demonstrated the safety and efficacy of LV Only in Boston Scientific devices.
