Pacing Using Cardiac Implantable Electric Device During Transcatheter Aortic Valve Replacement (TAVR)
- Cohort study
Authors' conclusion
Internal pacing using a CIED is safe and feasible without differences of procedural time and technical success and might reduce bleeding rates.
Study context
- Population
- Patients with a cardiac implantable electric device (CIED) undergoing TAVR
- Participants
- 486 patients
- Exposure
- Pacing via CIED vs transient pacemaker during TAVR
- CIEDn = 150
- Transient pacemakern = 336reference
- Outcome
- Procedural safety and feasibility of internal pacing with a CIED in TAVR
Main finding
As reported in the abstract
Technical success (VARC-3) and procedure duration
- No differences in technical success (VARC-3) or procedure duration between groups
Observational data: associations, not effects.
Safety
| Outcome | P value |
|---|---|
| Bleeding (VARC-3 type ≥2) · 2.0% vs 13.1%; significantly higher with transient pacers | P < 0.01 |
CIED impairment and surgical revision after TAVR
- CIED impairment, only when pacing by transient pacer
- 2.3%
- Surgical revision of the CIED when transient pacemakers were used
- 1.3%
