Valvular & structural heart disease
Cardiac implantable electronic device implantation and function after transcatheter tricuspid valve replacement
Authors' conclusion
After TTVR, bradyarrhythmias necessitating pacemaker implantation were common, and CIED implantation, mainly consisting of leadless pacemaker implantation, was successful in all cases. In patients with preexisting CIEDs, all TTVR procedures were performed successfully, though lead-related complications did occur.
Study context
- Population
- Patients undergoing transcatheter tricuspid valve replacement (TTVR)
- Participants
- Sixty-three patients
- Exposure
- TTVR in patients with vs without existing cardiac implantable electronic devices (CIEDs)
- No CIEDn = 42
- Existing CIEDn = 21
- Outcome
- CIED outcomes after TTVR: incidence of bradyarrhythmias and pacemaker implantation, and outcomes with preexisting CIEDs
Main finding
As reported in the abstract
Bradyarrhythmias requiring pacemaker implantation (no CIED)
No CIED
30.1%
13
- Leadless pacemakers implanted successfully
- 13
- Tricuspid valve sparing transvenous pacemaker implanted successfully
- 1
Observational data: associations, not effects.
Further findings
Outcomes with existing CIED · postprocedurally and at short-term follow-up
- Remaining devices had normal function; all TTVR procedures with "jailed" leads performed successfully
Safety
- Patients with an RV pacing lead with acute lead dislodgment requiring leadless pacemaker
- 1
- Remaining devices: normal function postprocedurally and at short-term follow-up
