Leadless Atrial Pacing Targeting Bachmann Bundle for Atrial Resynchronization: A Single Center Registry
Authors' conclusion
The BBLAP implant technique presented in this registry is feasible and reduced IACD. Further study on the effect of BBLAP on AF burden is needed.
Study context
- Population
- Adults with sinus node dysfunction and baseline P wave duration >120ms undergoing Bachmann bundle leadless atrial pacemaker implantationenrolled, 17 had successful BBLAP
- Participants
- 21 adults
- Exposure
- Baseline and BBLAP left atrial conduction time (LACT) and P wave duration (PWD), axis, and morphology were compared.
- BBLAPn = 17
- Outcome
- BBLAP implant success
Methodological detailsprospectively enrolled, consecutive adults
- Prospectively enrolled
- Consecutive adults
Main finding
As reported in the abstract
Successful BBLAP
17
81%
Observational data: associations, not effects.
Further findings
PWD, among those with successful BBLAP · reduction with BBLAP
reduction 37 (±13) ms · P < 0.001
LACT · decreased with BBLAP
mean difference 35 (±15) ms · P < 0.001
P wave axis with BBLAP
- Inferiorly directed in all cases
Negative terminal P wave in inferior leads at baseline
- Corrected with BBLAP
- 8/8
Coronary sinus (CS) activation shift from proximal-distal to mid- or distal-proximal during BBLAP
- Patients with shift
- 13/17
Safety
- No complications in all cases
