Clinical Evidence

Advanced CRT Optimization

Every patient deserves life-changing therapy. Abbott's next generation CRT-D solutions make it possible for you to achieve clinically meaningful outcomes:

100% of patients had a narrower QRS when SyncAV™ CRT technology was optimized1

  • CRT-induced QRS narrowing has been shown to improve clinical outcomes for heart failure patients2,3

22% fewer heart failure hospitalizations for patients with SyncAV CRT technology enabled vs. patients with the technology disabled4

87% response rate shown in IDE study subgroup with anatomically programmed separation using MultiPoint™ pacing5

  • In a separate study, MultiPoint pacing led to significantly more responders and fewer non-responders vs. biventricular pacing (p < 0.05)6
