Tricuspid Valve Dysfunction Caused by Right Ventricular Leads

Abstract

Tricuspid regurgitation is increasingly recognized as a clinically significant valvular condition. The role of multiple pacemaker and implantable cardiac defibrillator leads in distortion of the valve structure and the risk of trauma to the valve and subvalvular apparatus with lead extraction contribute to the development of tricuspid regurgitation (TR). There is a clinical imperative to better understand the optimal way to diagnose lead-related TR, risk factors for the development of TR, and optimal strategies to mitigate this problem.
