Key result
Quadripolar LV lead in the coronary sinus avoids a fourth surgery and achieves reasonable pacing thresholds.
Why the study?
In the presence of a prosthetic tricuspid valve, permanent pacing is challenging due to right ventricle inaccessibility, and single LV leads in the coronary sinus have limitations regarding sensing and threshold.

May avoid reoperation in select lead revision cases; hypothesis-generating and requires prospective validation.
Case Report (n=1)
Quadripolar LV-only single lead pacing in the coronary sinus offers a less invasive alternative to epicardial lead placement in patients with tricuspid mechanical valves and lead malfunction.
Grazina et al. (2022) conducted a case report in Prosthetic tricuspid valve and recurrent syncope due to lead malfunction (n=1). Quadripolar left ventricle single lead pacing in the coronary sinus was evaluated on Prevention of surgical intervention and achievement of reasonable LV sensing and pacing threshold. Placement of a quadripolar left ventricular lead in the coronary sinus prevented a fourth surgical intervention and achieved reasonable sensing and pacing thresholds.
