Tricuspid regurgitation ( TR ) produced by endocavitary leads ( EL ) from permanent pacemakers and implantable cardiac defibrillators is a well‐known complication of this procedure. The EL may damage or interfere with tricuspid valve function causing mechanical interference of the valve leaflets leading to incomplete valve closure. It is important to recognize this mechanical complication because it could be corrected by repositioning the lead. In this case report we demonstrate how three‐dimensional transthoracic echocardiography permits to obtaining an en face view, which allows simultaneous visualization of the 3 moving leaflets during the cardiac cycle, their attachment to the tricuspid annulus and the pattern of leaflet coaptation. Thus, we propose three‐dimensional transthoracic echocardiography as the tool of choice to evaluate TR related to EL , to evaluate the necessity of repositioning the lead if severe regurgitation or tricuspid valve malfunction are demonstrated.
