Real time three-dimensional echocardiography successfully clarified the mechanism of severe tricuspid regurgitation by visualizing the ventricular lead's interference with the tricuspid valve.

Real-time 3D echocardiography is useful for identifying the exact mechanism of pacemaker lead-induced severe tricuspid regurgitation when 2D echocardiography is insufficient.

May clarify pacemaker lead-related tricuspid regurgitation when 2D imaging is inconclusive; leaves open need for prospective validation.
Pacemaker leads may impair tricuspid valve coaptation and they are a well-known cause of mild tricuspid regurgitation. Occasionally, right ventricular leads worsen tricuspid regurgitation over time and patients develop late-onset symptoms of right-sided heart failure. The exact mechanism of this clinical entity is rarely identifiable by 2D-echocardiography only. This case report details a patient with severe tricuspid regurgitation secondary to immobilization of the anterior leaflet of the tricuspid valve by a permanent ventricular pacing lead. The mechanism of regurgitation was clarified by real time three-dimensional echocardiography that showed the location of the ventricular lead and its interference with the tricuspid valve.
