Ambulatory AV synchronous pacing over time using a leadless ventricular pacemaker:
Primary results from the AccelAV study

Larry A. Chinitz, M.D., FHRS, Mikhael F. El Chami, M.D., FHRS, et al.


 

Results1 

Sustained resting AV synchrony

85.4% and stable through three months

Improved ambulatory AV synchrony

82.6% with optimized programming

No upgrades through three months

No major complications due to pacemaker syndrome

Improved ambulatory AV synchrony with optimized programming1

Podcast 

Listen now to the podcast on the Micra™ AccelAV study from Alphons Vincent, Medtronic Medical Affairs Director for Western Europe. 

|

Purpose1 

To report on the performance of the Micra™ AV leadless ventricular pacemaker with accelerometer-based algorithms that provide AV synchronous pacing. 


Study design1

Prospective, single-arm, multicenter, global study

- 152 subjects from 20 centers in the U.S. and Hong Kong were implanted with a Micra™ AV

– 54 with complete AV block and normal sinus function (primary analysis cohort)

- 20 with complete AV block, normal sinus function, and optimized programming (Optimized sub-study cohort)
