Ambulatory AV synchronous pacing over time using a leadless ventricular pacemaker:
Larry A. Chinitz, M.D., FHRS, Mikhael F. El Chami, M.D., FHRS, et al.
Primary results from the AccelAV study
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)
