Key result
Extracting looped transvenous leads reduces tricuspid regurgitation in small case series.
Why the study?
Transvenous leads cause iatrogenic tricuspid regurgitation, and it is commonly believed that lead extraction does not reduce regurgitation due to procedural valve trauma.
Does extraction of looped transvenous pacing leads reduce tricuspid regurgitation in patients with lead-induced TR?

Does extraction of looped transvenous pacing leads reduce tricuspid regurgitation in patients with lead-induced TR?
Extraction of looped transvenous pacing leads can lead to clinically significant reductions in tricuspid regurgitation, challenging the common belief that extraction causes inevitable valve trauma preventing improvement.
Montgomery et al. (2017) conducted a case report in Tricuspid regurgitation associated with looped transvenous pacing leads (n=3). Extraction of looped transvenous pacing leads was evaluated on Reduction in tricuspid regurgitation. Extraction of transvenous leads looped across the tricuspid valve resulted in clinically significant reductions in tricuspid regurgitation in three cases.
