Successful Extraction of Entrapped CIED Lead After TTVR

Key Result

Extraction of entrapped RV leads was feasible, with leadless pacemakers being a viable alternative for RV pacing in TTVR cases.

Key Points

The research aims to evaluate the feasibility of extracting entrapped RV leads without affecting TTVR device positioning.
Analyzed techniques for lead extraction
Monitored device positioning pre-and post-extraction
Considered leadless pacemakers as alternative pacing options
Successful lead extraction was achieved in cases without device malposition
Leadless pacemakers were identified as viable alternatives for RV pacing

Structured PICO

Is extraction of entrapped RV leads after TTVR feasible without causing device malposition, and are leadless pacemakers a viable alternative?

Population

Patients with entrapped cardiovascular implantable electronic device (CIED) right ventricular (RV) leads after transcatheter tricuspid valve replacement (TTVR)

Intervention

Extraction of entrapped RV lead and implantation of leadless pacemaker

Outcome

Feasibility of lead extraction without TTVR device malposition

Extraction of entrapped RV leads post-TTVR is feasible without dislodging the valve, and leadless pacemakers offer a viable pacing alternative.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

Extraction of entrapped RV leads without causing TTVR device malposition may be feasible, and leadless pacemakers can be considered a technically viable alternative for RV pacing in TTVR.
