Permanent pacemakers and implantable cardioverter-defibrillators with right ventricular intracardiac leads can induce tricuspid valve dysfunction through various mechanisms.
What are the pathophysiologic effects, diagnostic strategies, and treatment options for tricuspid valve dysfunction induced by right ventricular intracardiac device leads?
This review outlines the mechanisms, diagnosis, and management of tricuspid valve dysfunction caused by right ventricular pacemaker or defibrillator leads.
Abstract Although thought to be a rare event, permanent pacemakers and implantable cardioverter‐defibrillators with right ventricular intracardiac leads have the potential to induce tricuspid valve dysfunction. Adverse lead‐valve interactions can take place through a variety of mechanisms including damage at the time of implantation, leaflet pinning, or long‐term fibrosis encapsulating the leaflet tissue. Clinical manifestations can display a wide range of severity, as well as a highly variable time span between implantation and hemodynamic deterioration. This review aims to describe the potential pathophysiologic effects of intracardiac device leads on the tricuspid valve, with a focus on ideal diagnostic strategies and treatment options once lead‐induced valvular dysfunction is suspected.
Trankle et al. (Mon,) conducted a review in Tricuspid regurgitation due to right ventricular intracardiac leads. Right ventricular intracardiac leads (permanent pacemakers and ICDs) was evaluated. Permanent pacemakers and implantable cardioverter-defibrillators with right ventricular intracardiac leads can induce tricuspid valve dysfunction through various mechanisms.
