Gallant HF

Cardiac Resynchronization Therapy Defibrillator (CRT-D)

 Gallant HF device with myMerlinPulse app shown on phone


Optimize Patient Outcomes

Meet your heart failure (HF) patients' changing needs with our latest generation of CRT technology:

SyncAV™ Plus CRT technology offers dynamic AV timing to ensure electrical resynchronization.

22% fewer HF hospitalizations
for patients with SyncAV™ CRT technology enabled vs. patients with the technology disabled1

100% of patients
had a narrower QRS2

MultiPoint™ pacing delivers multiple LV pacing pulses per cardiac cycle in both LV-only and biventricular pacing modes.

87% response rate
shown in the IDE study subgroup with anatomically programmed separation3

In a separate study, MultiPoint pacing led to significantly more responders and fewer non-responders vs. biventricular pacing (p <0.05)4

Faster, More Intuitive Programming

Gallant HF CRT-D solutions offer simple setup and customizable programming:

  • 2X faster vector testing
  • 13 vectors and 4 pacing electrodes provide more options and greater control
