Extraction of looped transvenous pacing leads to reduce tricuspid regurgitation.

Transvenous leads are a known source of iatrogenic tricuspid regurgitation. It is commonly held that extraction of chronic pacing and defibrillator leads will not reduce this, due to the inevitable trauma to the valve associated with the procedure. We demonstrate three cases of clinically significant reductions in tricuspid regurgitation after extraction of leads that were looped across the tricuspid valve.
