Key result
Managing tricuspid regurgitation by extracting a long-indwelling lead is often unsuccessful in reversing the regurgitation and could result in further damage to the tricuspid valve apparatus.
Why the study?
Tricuspid regurgitation is common with transvenous RV pacing or ICD leads, but lead extraction often fails to reverse regurgitation and risks TV damage.
Extracting long-indwelling transvenous leads to manage tricuspid regurgitation is often unsuccessful and risks further damage to the valve apparatus.
Lead extraction for tricuspid regurgitation warrants caution; leaves open optimal management strategies in long-indwelling leads.
Tricuspid regurgitation (TR) is commonly encountered in patients with transvenous right ventricular (RV) pacing or implantable cardioverter-defibrillator (ICD) leads.1,2 Possible etiologies for TR in the presence of transvenous leads include lead impingement of the tricuspid valve (TV) leaflets or papillary muscles. Non-lead-related mechanisms for TR may also contribute, even if transvenous leads are present. Managing TR by extracting a long-indwelling lead is often unsuccessful in reversing the regurgitation and could result in further damage to the TV apparatus.

Ibrahim et al. (2022) conducted a review in Tricuspid regurgitation in patients with transvenous right ventricular pacing or ICD leads. Extracting a long-indwelling lead was evaluated. Managing tricuspid regurgitation by extracting a long-indwelling lead is often unsuccessful in reversing the regurgitation and could result in further damage to the tricuspid valve apparatus.
